Which factory produces hydrogen sulfide as a by-product?
Thread Content
One of our projects requires hydrogen sulfide, with an annual supply volume of at least 1,000 tons preferred. If anyone knows anything about this, please help!
This reminds me of a previous project in which ethanethiol was synthesized using hydrogen sulfide and ethylene, which are by-products of petroleum; the economic benefits were much better than those of producing sulfonic acid.
Many companies use hydrogen sulfide to produce sulfur!
Hehe, I got it wrong for the second floor; it’s for producing ethanethiol!
The purity of the hydrogen sulfide produced as a by-product is quite low, and since factories generally produce sulfur using the Claus process, hydrogen sulfide is usually synthesized by combining sulfur with hydrogen. This post was last edited by dqlhb on 2008-3-6 09:52]
Refineries equipped with secondary processing units generate acidic gases, especially those that process high-sulfur crude oil, as they produce more such gases. The main component in acidic gas is hydrogen sulfide; I wonder if this is the gas you need?
Most local refineries in Shandong process high-sulfur fuel oil, resulting in a relatively high volume of acidic gases.
The project we have developed uses hydrogen sulfide as a raw material; therefore, any manufacturer that has easy access to hydrogen sulfide resources will have a significant advantage by adopting this project, as it not only ensures profitability for the manufacturer but also eliminates the need for further processing of hydrogen sulfide.
Almost every oil refining company has H2S, but most produce sulfur using the Claus process. Moreover, the price of sulfur has now risen from 500 RMB per ton to 4800 RMB per ton. When working on other projects such as thioethers and dimethyl sulfoxide, the costs need to be taken into consideration. Upstairs, in the vicinity of Tianjin, there are refineries such as Yanshan Petrochemical, Sinopec Tianjin Branch, Dagang Petrochemical, Huabei Petrochemical (Renqiu), Cangzhou Refining & Chemical, and Zhongjie Petrochemical (Huanghua)
Now that sulfur prices have dropped, the market for hydrogen sulfide projects is doing well.
All refineries that process high-sulfur oils and sulfur-containing oils produce large amounts of hydrogen sulfide.
