Toyo Engineering Corporation and BASF have entered into a cooperative agreement to market and sell a gas purification technology specifically designed to purify synthesis gas streams for use in Integrated Gasification Combined Cycle (IGCC) power plants or for processing for chemical and fuel products.
The technology, which will be marketed under the brand name PuraTreat A selectively removes sulfur compounds such as hydrogen sulfide or carbonyl sulfide from synthesis gas streams based on coal.
Two other BASF products in the family, PuraTreat F and R, are high-performance solvents used for the removal of CO2 and H2S, and the selective removal of H2S respectively, specifically in gas streams containing olefins and/or oxygen. In addition to high stability in the presence of olefins and oxygen, the use of PuraTreat is associated with negligible vapor pressure. The products also offer particularly low hydrocarbon solubility (lower than water). PuraTreat F and R contain no ethanolamines. Both are non-toxic and biodegradable.
Compared to currently used processes, the new PuraTreat A technology is more energy efficient, more flexible and requires significantly less capital investment for grassroots plants, according to BASF.
This partnership strengthens the relationship between Toyo and BASF as both companies have already successfully worked together on numerous projects including acid gas sweetening using BASF’s aMDEA technology—short for “activated methyl diethanolamine.”
The BASF process has been known for a long time, and is used in more than 220 plants worldwide to scrub natural and synthesis gases.
Due to the high oil and gas prices coal gasification has gained importance over the last few years. We see the cooperation as an opportunity to diversify into new segments.—Dr. Rupert Wagner, BASF Intermediates division
