BASF, Toyo in gas purification link

Technology for IGCC power plants and chemical products such as methanol.
Ludwigshafen, Germany -- BASF and Toyo Engineering Corp of Chiba, Japan, are to cooperate in supplying technology to purify synthesis gas streams for Integrated Gasification Combined Cycle (IGCC) power plants and chemical products such as Methanol.
The technology, which will be marketed under the brand name PuraTreat A, is designed to selectively remove sulphur compounds such as hydrogen sulfide or carbonyl sulfide from synthesis gas streams based on coal.
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, BASF claims.
Toyo and BASF have already worked together on various projects including acid gas sweetening using the German group’s activated methyl diethanolamine-based amine scrubbing technology for the removal of acid gases such as CO2.
The BASF process has been used in over 220 plants worldwide to scrub natural and synthesis gases, said Dr. Rupert Wagner, a gas scrubbing expert at BASF Intermediates division. “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.”
