According to market news, the Ministry of Commerce recently approved and issued the allowable import volume of the first batch of crude oil for non-state trade in 2022, with a total amount of 109.03 million tons, a decrease of 11% compared with the same period in 2021. The quota of some independent refineries in Shandong and Northeast China was reduced.
After the impact of the epidemic on the national economy in 2020, Saudi Arabia, the world’s largest oil exporter, continued to pick up its foreign trade in 2021. According to the statistics released by the Saudi National Bureau of statistics on the evening of the 26th local time, Saudi Arabia’s foreign exports in October 2021 increased by 90% over the same period last year. Affected by the rising oil price, crude oil exports reached 82.4 billion Saudi Riyals (about 140.08 billion yuan), an increase of 123.1% over October 2020; The export volume of non oil commodities increased by 25.5% over the same period last year, and the total export volume also increased by 12.2% over September 2021.
Earlier this month, the Saudi Ministry of Finance announced the national budget for 2021-2022, which is expected to have a fiscal surplus for the first time in nine years. The world economic outlook report released by the International Monetary Fund in October also predicts that Saudi Arabia’s economic growth will reach 2.8% in 2021 and further increase to 4.8% in 2022.

Product Description
Iso-pentane(2-Methylbutane)  Applications.
Isopentanes are some of the primary blowing agents used in the production of polystyrene foam and other foams. Usually, a mixture of n-, i-, and increasingly cyclopentane is used for this purpose. Because of its low boiling point, low cost, and relative safety, pentane is used as a working medium in geothermal power stations. It is added into some refrigerant blends as well.
Isopentanes are relatively inexpensive and are the most volatile alkanes that are liquid at room temperature, so they are often used in the laboratory as solvents that can be conveniently evaporated. Pentanes are miscible with most common nonpolar solvents such as chlorocarbons, aromatics, and ethers. They are also often used in liquid chromatography.  Isopentane is also used in a closed loop in geothermal power production to drive turbines. Isopentane is used, in conjunction with dry ice or liquid nitrogen, to freeze tissues for cryosectioning in histology.
