Petroleum Products Made from a Barrel of Crude Oil

What is crude oil and what are petroleum products?

We call crude oil and petroleum fossil fuels because they are mixtures of hydrocarbons that formed from the remains of animals and plants (diatoms) that lived millions of years ago in a marine environment before the existence of dinosaurs. Over millions of years, the remains of these animals and plants were covered by layers of sand, silt, and rock. Heat and pressure from these layers turned the remains into what we now call crude oil or petroleum. The word petroleum means rock oil or oil from the earth.

Crude oil and other hydrocarbons exist in liquid or gaseous from in underground pools or reservoirs, in tiny spaces within sedimentary rocks, and near the earth’s surface in tar (or oil) sandsPetroleum products are fuels made from crude oil and hydrocarbons contained in natural gas. Petroleum products can also be made from coal, natural gas, and biomass.

Products made from crude oil

After crude oil is removed from the ground, it is sent to a refinery where different parts of the crude oil are separated into useable petroleum products. These petroleum products include gasoline, distillates such as diesel fuel and heating oil, jet fuel, petrochemical feedstocks, waxes, lubricating oils, and asphalt. Learn more in Refining crude oil—inputs and outputs

A U.S. 42-gallon barrel of crude oil yields about 45 gallons of petroleum products in U.S. refineries because of refinery processing gain. This increase in volume is similar to what happens to popcorn when it is popped. A corn kernel is smaller and more dense than a popped kernel. The amount of individual products produced varies from month-to-month and year-to-year as refineries adjust production to meet market demand and to maximize profitability.

What’s in a Barrel of Oil? The 42-Gallon Breakdown

Have you ever wondered what, exactly, is in a barrel of oil? It’s certainly not full of monkeys, that’s for sure. The obvious answer, you might be thinking, is 42-gallons of gooey, black crude. And that’s technically correct. However, there is so much more potential in that barrel of oil than fossil fuel alone.

One barrel = 42 US gallons = 159 litres = an abundance of possibilities.

What is crude oil?
First, we’ll start with the basics: what is crude oil? Also known as petroleum, crude oil is a liquid mixture of hydrocarbons, organic compounds, and some small amount of metal found below the earth’s surface. Petroleum is created through the heating and compression of very old organic matter (prehistoric plants and animals) over a long period of time. Crude oil is considered a fossil fuel because it is the natural byproduct of decaying plants and animals.

Over this long period of time, the prehistoric algae, zooplankton, and other organic matter settled to the bottom of ancient bodies of water where it all combined with mud. The pressure from layers of sedimentation exposed the organic matter and mud to high temperatures. Through diagenesis, the chemical composition first turned to a waxy compound called kerogen. Then, with increased heat, the matter turned into a liquid through catagenesis. That liquid is crude oil.

So far, our barrel is full of 50-97% hydrocarbons, between 6-10% organic compounds, and less than 1% metal.

What else is in a barrel of oil?
Untapped possibilities.

Every barrel of unrefined oil also has the potential to be transformed into a number of different products. But before anything can be made, the petroleum must first be refined.

Since crude oil contains various types of hydrocarbons, these need to be separated to form the desired end product (because not all petroleum products are created equally). Fractional distillation occurs when crude oil is heated and the different components of the oil are extracted in stages through their different vaporizing temperatures.

Once refined, crude oil can be transformed into all sorts of useful products, including fuels and other oil-based lubricants.

However, while gasoline production is one of the largest petroleum-based products currently manufactured, gas makes up less than half of a barrel of crude oil.

If gasoline accounts for 46% of our oil barrel, what’s happening to the other 54%?

Let’s break it down for you:

Twenty-six percent of the remaining crude oil goes into the production of diesel and other fuels.

About nine percent is used to make jet fuel.

Three percent of the crude oil goes into the production of asphalt to pave roads and parking lots.

One percent of this goes into the manufacturing of lubricants: the greases and fluids that help keep our world running smoothly.

The remaining fifteen percent is classified as other. These —bottom of the barrel ” petrochemical products include thousands of different items, ranging from makeup to medicine.

In fact, we highlight these —Bottom of the Barrel ” products in our Petroleum Product of the Week series to showcase just how many products we rely on daily are made using petroleum (at some point in the process).

Did you know that aspirin is a petroleum product? How about food coloring and vape juice? If you dress up your smile with some lipstick, your favorite brand might just be a petroleum product, too.

Every time you reach for something plastic or something made from synthetic rubber, you’ve got yourself your very own petroleum product. Glasses? Check. Styrofoam? Check. Toothbrush? Check. Even money contains elements of petroleum.

How much oil do we consume?
This is an incredibly difficult question to answer, to be quite honest. One person’s oil consumption is entirely dependent on another person’s consumption, as well as some random company’s consumption. Oil consumption extends well beyond transportation (even if that’s the biggest consumer of oil).

For some perspective, though, the US consumed approximately 19.7 million barrels of petroleum per day (b/d) in 2016. That same year, motor gasoline consumption averaged about 9.3 million b/d. Even if you could account for how much fuel you consume, there’s difficulty in accounting for how much fuel went into transporting your groceries— or what percentage of a —barrel ” went into manufacturing your t-shirt or dish soap.

2020/11/13. USD TO CNY TODAY.

Actual USD to CNY exchange rate equal to 6.6075 Chinese Yuans per 1 Dollar. Today’s range: 6.6050-6.6260. Previous day close: 6.6130. Change for today -0.0055, -0.08%

Separated products:
The mixed C5 in Shandong increased by 20 yuan / ton to 3100-3230 yuan / ton, while that in East China stabilized at 2950-3060 yuan / ton. The remaining C5 is 3050-3300 yuan / ton in Northeast China, 2950-3050 yuan / ton in North China, 3000-3050 yuan / ton in Central China and 3000-3130 yuan / ton in South China.
The main delivery price of isoprene in China remained stable at 8200 yuan / ton, and the market inquiry was positive. SIS increased production and increased demand for isoprene. At present, the profits of isoprene rubber and sis are better, which supports the isoprene market, and isoprene maintains firm.
The mainstream self raised price of m-pentadiene in China is 8400-8700 yuan / T. Sinopec is still in shutdown, and the price of adhesive resin is firm, which has certain support for the isoprene market. The supply of m-pentadiene is slightly tight, and the market is slightly firm.
The domestic market of dicyclopentadiene continues to be weak, and the self raised price is around 4400-4850 yuan / ton, and the enthusiasm for receiving goods from downstream has not significantly increased. In terms of UPR, affected by the high price of maleic anhydride, the start-up of DC series is difficult to recover. Although DCPD hydrogenated resin has a stable demand for bicycles, it mostly uses digestion inventory or its own raw materials, so it has limited procurement in the spot market, and the market continues to maintain a weak trend in the near future.
rosin
At present, it is difficult to reduce the price of resin, and the downward rate of rosin price slows down. However, in the short term, the price of rosin is temporarily unstable, and rosin resin factories will wait and see. The market price of turpentine is 27000-28500 yuan / ton in Jiangxi, 11400-15100 yuan / ton in Guangdong, 11400 yuan / ton in wetland, 13500 yuan / ton in Yunnan, 15000 yuan / ton in Fujian, 11400 yuan / ton in Jiangxi, 14500-15000 yuan / ton in 138 resin, 14700-15500 yuan / ton in 145 resin, and 27000-28500 yuan / ton in market price of turpentine. In the short term, the rosin market is still out of stock. Most of the manufacturers think that the price of rosin will rise after the adjustment of rosin stage by stage. However, in the short term, the rosin price fluctuates, and the purchase quantity of rosin resin factory is scarce, and the supply of rosin resin is scarce, so there is more single discussion.
C5 petroleum resin:
At present, the mainstream transaction price of C5 petroleum resin for road marking paint is 10000-10600 yuan / ton. Although the demand in the north is low, the supply of the manufacturer is insufficient, and the manufacturer mainly supplies adhesive resin, and some parts are still out of stock. The manufacturer has few stock, and the price is stable within the overall range; the transaction price of C5 petroleum resin for adhesive (M-E) is operating in the range of 12000-13000 yuan / T Due to the concentration of orders, the continuous shortage situation, and the fluctuation of rosin price, the operating rate of resin factory is low. In the short term, C5 petroleum resin manufacturers mainly execute orders and operate stably in the price range.

Weekly Product Price Review
The price of n-Alkanes series products is stable this week. 1. The price of gasoline rose, and the price of pentane foaming agent / pentane blends increased slightly; 2. The domestic price of Isohexane and Isopentane was stable, the price of n-Octane was stable, and the price of dearomatized solvent oil fell; 3. High purity n-Hexane was still out of stock in the short term, and the price rose steadily.

Daily Price Changes on Pentanes, Hexanes, Heptanes and Octanes | November 12, 2020

Information Morning Post : n-Pentane, n-Hexane, n-Heptane, Octane, Isopentane, Isohexane, Pentane Blends and D Solvents

Release Time: November 12, 2020 08:22

The energy minister of Algeria said that OPEC may extend the current scale of production reduction to 2021, and the possibility of increasing the reduction is not ruled out. International oil prices continue to rise, but the epidemic situation in Europe and the United States is still very serious, which has restrained the increase. In terms of n-Pentane, Isohexane, Isopentane, n-Hexane, n-Heptane and Pentane Blends, the sales situation of each manufacturer was not satisfactory yesterday, at present, n-alkane series products like n-Pentane and n-Octane are sold less, and they mainly focus on delivery of the backlog orders today. In the aspect of pentane blends, the manufacturers are operating in low invertory level, and therefore there is enough confidence for price stability support because the market is out of stock. However, the current price is close to the high level, and some downstream regions are in a state of resistance. It is expected that the market will maintain stable operation today.

Positive progress in vaccine research and development in Europe and the United States has boosted demand confidence. In addition, Saudi Arabia suggested that oil producing countries could adjust their current production reduction policies, and international oil prices continued to rise. However, the overseas epidemic situation still worried the market and restrained the increase. In terms of n-Pentane, n-Hexane, n-Heptane, Isopentane, Isohexane, pentane blends and D20 Solvent, at present, for non-n-alkane hydrocarbon products, although the market price of raw materials is lower, and the cost pressure of manufacturers is relieved, it is still in the loss range. The resumption of downstream work is basically normal, but there is still a certain distance to return to normal demand. Especially, the sharp drop of pentane foaming agent product price has reduced the planned production of pentane foaming agent products of various manufacturers more or less, as for pentane blowing agent products, although product price competitiveness has increased, but sales price pressure increases, from all aspects are negative leading. The refinery’s shipment was poor yesterday, and it is expected to be dominated by shipment today. In the aspect of mixed C5, the refinery inventory is running at a low level, and there is sufficient base gas for price rising. However, the current price is close to the high level, and some downstream units are in a state of resistance. It is expected that the market will maintain stable operation and rise sporadically. The mainstream ex factory price in Shandong is 3100-3230 yuan / ton, and that in East China is 2950-3060 yuan / ton.

2020/11/11. USD TO CNY TODAY.

Actual USD to CNY exchange rate equal to 6.6026 Chinese Yuans per 1 Dollar. Today’s range: 6.5910-6.6050. Previous day close: 6.6140. Change for today -0.0114, -0.17%. 

Separated products:
Mixed C5: Shandong increased by 100 yuan / ton to 3100-3200 yuan / ton, while eastern China stabilized at 2950-3060 yuan / ton. The amount of C5 surplus is 3050-3300 yuan / ton in Northeast China, 50 yuan / ton in North China, 3000-3050 yuan / ton in Central China and 3000-3130 yuan / ton in South China.
The main delivery price of isoprene in China is 8000 yuan / ton, and the market inquiry is positive. SIS is expected to increase production and demand for isoprene this month. At present, the profits of isoprene rubber and sis are better, which supports the isoprene market. Isoprene is expected to rise today.
The mainstream self raised price of m-pentadiene in China is 8400-8700 yuan / T. Sinopec is still in shutdown, and the price of adhesive resin is firm, which has certain support for the isoprene market. The supply of m-pentadiene is slightly tight, and the market is slightly firm.
The domestic market of dicyclopentadiene is still weak. With the increase of maleic anhydride price, the bicyclic pressure will increase, and the price may continue to run downward. At present, DCPD hydrogenated resin is in operation and maintained, but the raw material inventory is relatively sufficient, and the intention of large-scale purchase is not high, and the double ring export is also reduced, and the domestic inventory is facing the risk of recovery. Affected by the sudden shutdown of LG cracking unit in South Korea, the export market may recover, and the industry will wait and see.
rosin
At present, it is difficult to reduce the price of resin, and the downward rate of rosin price slows down. However, in the short term, the price of rosin is temporarily unstable, and rosin resin factories will wait and see. The market price of turpentine is 27000-28500 yuan / ton in Jiangxi, 11400-15100 yuan / ton in Guangdong, 11400 yuan / ton in wetland, 13500 yuan / ton in Yunnan, 15000 yuan / ton in Fujian, 11400 yuan / ton in Jiangxi, 14500-15000 yuan / ton in 138 resin, 14700-15500 yuan / ton in 145 resin, and 27000-28500 yuan / ton in market price of turpentine. In the short term, the rosin market is still out of stock. Most of the manufacturers think that the price of rosin will rise after the adjustment of rosin stage by stage. However, in the short term, the rosin price fluctuates, and the purchase quantity of rosin resin factory is scarce, and the supply of rosin resin is scarce, so there is more single discussion.
C5 petroleum resin:
At present, the mainstream transaction price of C5 petroleum resin for road marking paint is 10000-10600 yuan / ton. At the beginning of the week, the orders of various manufacturers are concentrated, and the inventory is almost empty. The sporadic load of manufacturers is reduced, the supply is tight, and there is still partial shortage in the short term, and the price is mainly stable. The transaction price of C5 petroleum resin for adhesive is between 12000-13000 yuan / ton, and the price of rosin resin is at the beginning of the week In the short term, C5 petroleum resin is out of stock, and the focus is on the high-end price range.

What is the difference between GMP and GLP?

What is the difference between GMP and GLP?
Both Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) regulations are vitally related to laboratory testing. However, the two categories of regulation have notable differences, beginning with their end goal.

Good Manufacturing Practice

GMP is part of a quality system covering the manufacture and testing of pharmaceutical dosage forms or drugs and active pharmaceutical ingredients, diagnostics, foods, pharmaceutical products, and medical devices. GMPs are guidelines that outline the aspects of production and testing that can impact the quality of a product. Good manufacturing practices (GMP) are the practices required in order to conform to the guidelines recommended by agencies that control the authorization and licensing of the manufacture and sale of food and beverages, cosmetics, pharmaceutical products, dietary supplements, and medical devices. These guidelines provide minimum requirements that a manufacturer must meet to assure that their products are consistently high in quality, from batch to batch, for their intended use. The rules that govern each industry may differ significantly; however, the main purpose of GMP is always to prevent harm from occurring to the end user. Additional tenets include ensuring the end product is free from contamination, that it is consistent in its manufacture, that its manufacture has been well documented, that personnel are well trained, and that the product has been checked for quality more than just at the end phase. GMP is typically ensured through the effective use of a quality management system (QMS).
A Good Manufacturing Practices (GMP) Certificate can be issued by companies, which are able to document adherence to Good Manufacturing Practices, as outlined by the U.S. FDA, State Health Departments, or by another set of standards. Most countries prefer that GMP certificates be issued from a trade association, such as ACMA.

What are Good Manufacturing Practices (GMP)?

Good Manufacturing Practice (GMP)

  1. Establish Good Written Procedures.
  2. Qualify and Validate Processes.
  3. Identify Roles and Responsibilities.
  4. Keep All Records.
  5. Use the Right Facilities and Equipment.
  6. Assemble a Competent Team.
  7. Practice Good Hygiene.
  8. Maintain Facilities and Equipment.
  9. Ensure Quality.
  10. Use GMP Audit Checklists.

What is GMP contract manufacturing?
A GMP technical agreement ensures compliance to the current good manufacturing practices (cGMP). Need for a Technical Agreement. By defining a clear technical agreement, both parties know who will be responsible for what, thus avoiding conflicts and have defined a clear escalation route.

Is GMP the same as cGMP?
GMP is widely being used in the world when compared to CGMP. In fact, more than 100 different countries out there in the world tend to use GMP. However, only handful countries adhere to the guidelines of CGMP. GMP is widely applicable to a large number of situations out there in the world, when compared to CGMP.

What countries use GMP?
The World Health Organization version of GMP is used in over 100 other countries, mostly in the developing world. Similar GMPs are found in the EU, Australia, Canada, Japan, Singapore, and the Philippines. HACCP is used in the US, and is enforced by the FDA (for seafood and juice) and USDA (for meat).

What is a GMP lab?
GMP laboratories are laboratories that follow and systematically document adherence to Good Manufacturing Practice regulations, recognizing the importance of putting quality first and upholding production excellence at every step of the pharmaceutical manufacturing process.
