DMDS Applications in the Saudi Arabian Energy and Petrochemical Sectors

The petrochemical and refining landscape in Saudi Arabia represents one of the most demanding industrial environments globally. For operators seeking to optimize catalyst performance and extend the lifespan of high-temperature equipment, Dimethyl Disulfide (DMDS) has emerged as the industry-standard chemical agent.

This article explores the primary industrial applications of DMDS within the region and the logistical frameworks that support its distribution.

Catalyst Presulfiding in Hydroprocessing

In the refining sector, the efficiency of hydrodesulfurization (HDS) and hydrocracking units depends heavily on the activation of catalysts. These catalysts are typically delivered in a metal-oxide state and must be converted to an active metal-sulfide state through a process known as presulfiding.

DMDS is the preferred agent for this process due to its high sulfur content (approximately 68%) and its controlled decomposition temperature. When injected into the reactor, it decomposes into hydrogen sulfide ($H_2S$), ensuring a uniform and deep sulfidation of the catalyst bed. This precise activation results in higher activity levels, longer cycle lengths, and improved product quality for ultra-low sulfur diesel (ULSD) and gasoline.

Coking Inhibition in Ethylene Cracking

Ethylene production is a cornerstone of regional industrial output. One of the primary operational challenges in steam cracking is the accumulation of coke on the internal surfaces of radiant furnace tubes.

The application of DMDS serves as a critical anti-coking strategy. When introduced into the hydrocarbon feed, DMDS facilitates the formation of a protective metal-sulfide layer on the furnace tube walls. This passivation layer offers two distinct advantages:

1. Extension of Run Length: By reducing the rate of carbon deposition, plants can operate for longer periods between decoking cycles.
2. CO Reduction: It minimizes the catalytic formation of carbon monoxide, thereby improving the purity of the effluent stream.

Emerging Agricultural and Soil Treatment Uses

Beyond the oil and gas value chain, there is a growing focus on sustainable agricultural practices in the region. DMDS is increasingly utilized as a high-performance soil fumigant. As a viable alternative to phased-out chemicals like methyl bromide, DMDS effectively controls nematodes and soil-borne pathogens. Its rapid degradation in soil makes it a preferred choice for modern greenhouse operations and high-value crop production.

The Role of Local Distribution and Specialized Logistics

The effective utilization of DMDS in the Kingdom relies on a sophisticated supply chain managed by specialized industrial distributors. These local partners act as the essential bridge between global chemical manufacturers and domestic end-users.

Supply Chain Integration

Major holding groups and their dedicated petrochemical subsidiaries provide the necessary infrastructure for the safe handling of DMDS. Given the chemical’s distinct odor and hazardous nature, local distributors maintain specialized storage facilities and transport fleets that comply with stringent safety regulations.

Technical Support and Injection Services

The application of DMDS is often accompanied by specialized onsite services. Local providers often coordinate with technical experts to monitor injection rates and ensure optimal sulfiding during refinery turnarounds. This localized expertise reduces downtime and ensures that large-scale industrial projects remain on schedule.

Conclusion

As the regional energy sector continues to evolve toward higher efficiency and environmental compliance, the role of specialized chemicals like DMDS becomes even more vital. From ensuring the potency of refining catalysts to protecting ethylene furnaces and modernizing agriculture, DMDS remains a versatile tool in the Kingdom’s industrial arsenal.

For operators and plant managers, partnering with established local distributors remains the most effective way to secure a reliable supply of high-purity DMDS while benefiting from localized logistical support.

This analysis focuses on the price trend of 99% pure n-Heptane in the Central China region from April 14 to April 25, 2025. The data reveals a significant price change within this period.

On April 14, the price of 99% n-Heptane was relatively high in the Central China market. However, the price began to decline soon after, marking a noticeable and continuous downward trend. By April 25, the price stabilized at RMB 15,200/ton (~USD 2,080/ton), with no further changes on that day, showing a price fluctuation of 0.00%.

For purchasers, this price trend highlights several key points to consider. First, whether this downward trend is temporary or indicative of a long-term market shift is crucial. If the decline is only a short-term adjustment, prices may stabilize or even increase later. In this case, excessive stockpiling at the current low prices could lead to higher costs if prices rebound. On the other hand, if the price drop is due to fundamental industry changes, such as increased raw material supply or heightened market competition, buyers could take advantage of this opportunity to increase their purchasing volume within reasonable limits to lower their average procurement costs.

The supply side dynamics are also essential for purchasers to monitor closely. If new n-Heptane production facilities are launched or existing companies expand production, market supply could significantly increase. If demand remains stable or grows slowly, prices may continue to face downward pressure. Conversely, if production plants shut down or face maintenance issues, leading to reduced supply, prices could stabilize or rebound. Therefore, purchasers should stay informed about supply-side changes through communication with suppliers and industry news.

Additionally, the availability of substitutes should not be overlooked. In the chemical raw materials market, multiple alternatives with similar functions often exist. If the price of n-Heptane continues to fall, its relative cost-effectiveness may change. If comparable substitutes with better pricing emerge, purchasers may need to reassess their procurement strategies or even consider adjusting product formulas to incorporate these substitutes and reduce costs.

Industry policies and the development of upstream and downstream industries also influence n-Heptane prices. For instance, stricter environmental regulations could limit the production of n-Heptane, impacting both supply and prices. Similarly, changes in the demand from n-Heptane’s downstream industries will directly reflect on its price. Purchasers should stay attuned to industry policies and the trends in upstream and downstream industries to make more informed purchasing decisions in a complex market environment.

In summary, the price of 99% n-Heptane in Central China decreased in April 2025 and stabilized by the end of the month. In future procurement activities, buyers should carefully consider factors such as the su

As of April 25, 2025, the market price of industrial-grade n-Hexane, 60% in China remained at RMB 8,500/ton (~USD 1,160/ton), with zero fluctuation observed during the 11-day period from April 14 to April 25. This stability highlights several underlying features and trends within the domestic hexane market.

I. Analysis of Price Stability

The rare “zero-volatility” trend during this period may be attributed to a combination of the following factors:

1. Supply-Demand Equilibrium: The current balance between supply and demand in the chemical sector appears strong. Neither seasonal variations nor unexpected disruptions (such as transportation issues) occurred. Downstream procurement remained steady, and upstream production capacity experienced no major adjustments.

2. Cost and Policy Support: The cost of producing n-Hexane—linked to feedstocks like crude oil and natural gas—remained stable, preventing cost-driven price shifts. In addition, government oversight or industry coordination may have contributed to market stability by discouraging price surges that could pressure manufacturing costs.

II. Industry Context

This data reflects trends specific to the Chinese market and must be interpreted in the broader context of the industry:

• Demand Structure: n-Hexane is widely used as a solvent and chemical intermediate, especially in coatings, adhesives, and rubber processing. Its relatively low demand elasticity means usage doesn’t rapidly rise or fall. The current stability may indicate a flat downstream demand or improved efficiency reducing per-unit consumption. Notably, rising demand for high-purity solvents in the new energy sector (e.g., lithium battery adhesives) has not yet significantly impacted this traditional hexane segment.

• Market Competition: The domestic n-Hexane market is likely dominated by leading local producers, with moderate pressure from imports. Price stability suggests a relatively balanced and cautious competitive environment.

III. Risk Outlook: What Could Disrupt This Balance?

Despite the short-term calm, the following risks could cause price shifts:

1. Upstream Volatility: A surge in global crude oil prices—driven by geopolitical events or OPEC policy—could increase production costs and exert upward pressure on n-Hexane pricing.

2. Environmental and Regulatory Pressures: Stricter environmental regulations may cause plant shutdowns or capacity reductions, tightening supply. Carbon reduction targets could also increase costs for feedstock processing methods such as gas-to-olefins (GTO).

3. Substitution Risk: As VOC (Volatile Organic Compound) regulations tighten, alternatives like Isopentane may gain market share, diverting demand from traditional n-Hexane products.

IV. Strategic Recommendations

To navigate current conditions and prepare for potential changes, businesses should consider:

• Procurement Strategy: Continue just-in-time purchasing in the short term. Mid- to long-term, build a pricing alert system focusing on crude oil futures and policy developments.

• Production Efficiency: Chemical producers should optimize processes to reduce energy consumption and offset potential cost hikes. Explore high-value downstream applications such as electronic-grade solvents to enhance product margins.

• Market Diversification: Closely monitor regional demand within China. While national data shows stability, local pricing may vary due to logistics and other regional dynamics. Flexible resource allocation is key.

V. Long-Term Outlook

This current period of price stability may be temporary. Two key forces will shape the long-term trajectory:

1. Global energy transitions and their ripple effect on petrochemical chains.

2. Industrial upgrading in China, especially the shift toward high-end chemical materials.

If the new energy industry accelerates, demand for specialty solvents could surge, possibly triggering a structural transformation of the n-Hexane market. On the other hand, continued stagnation in traditional sectors may narrow future price fluctuations even further.

In summary, the stable price of n-Hexane, 60% in recent weeks is the result of balanced supply-demand dynamics, cost control, and a cautious market environment. Industry players should adopt a dynamic and flexible strategy to respond to potential disruptions and long-term transformation opportunities.
