Coking, the formation of undesirable carbon deposits within refinery equipment, is a persistent challenge that can lead to reduced efficiency, increased operational costs, and unplanned shutdowns. Di-Tert-Butyl Polysulfide (DTBPS) has emerged as a valuable chemical solution that not only functions as a sulfiding agent but also plays a significant role as a coking inhibitor for refineries. NINGBO INNO PHARMCHEM CO.,LTD. provides DTBPS that aids in mitigating these coking issues, contributing to more stable and productive refinery operations.

The mechanism by which DTBPS inhibits coking is rooted in its chemical structure and decomposition pathway. Unlike some other sulfur compounds, DTBPS, when subjected to the high temperatures and pressures within refinery units, decomposes in a manner that helps to passivate active sites on metal surfaces that would otherwise catalyze coke formation. By converting to hydrogen sulfide (H2S) and other byproducts like isobutane, it helps to maintain a cleaner process stream. This is particularly important in processes like hydrotreating and hydrocracking where high temperatures can accelerate the polymerization of hydrocarbons and the subsequent formation of coke.

The comparison between DTBPS and DMDS highlights these differences. While both are used for catalyst sulfiding, the decomposition products and stability of DTBPS can be more advantageous in preventing fouling. Reports on DTBPS vs DMDS performance often indicate that DTBPS can lead to a more stable operation with less risk of intermediate product formation that could contribute to fouling. The fact that DTBPS is a safer sulfiding agent alternative to DMDS also means that handling and injection protocols can be less complex, making it easier to implement effective anti-coking strategies.

Moreover, as an industrial lubricant additive, DTBPS contributes to the overall performance of lubricants by enhancing their thermal stability and reducing oxidative breakdown, which can also be linked to deposit formation. This dual functionality makes it a versatile component in the chemical industry.

For refineries looking to optimize their operations and minimize the impact of coking, incorporating DTBPS into their chemical treatment programs is a strategic move. The chemical properties of DTBPS, particularly its role in maintaining catalyst activity and inhibiting coke formation, make it a preferred choice for many modern facilities. NINGBO INNO PHARMCHEM CO.,LTD. offers DTBPS that embodies these benefits, supporting the industry's drive for efficiency and sustainability.
