Gas Research Institute United States

In April 2000, GRI merged with the Institute of Gas Technology (IGT) to form the Gas Technology Institute (GTI) geared to meet the needs of a more competitive, 

The R D activities of GRI led to a group of two patents, for gas sweetening (and also useful for flue gas treatment), based on biocatalytic processes for the selective removal of sulfur compounds in the presence of other reactive gases. 

While the temperature and pressure conditions and inoculum usage may be practical, the reaction time, the investigated scale and the discontinuous nature of the process contribute to the difficulty of using this process for pretreatment operations. However, in cases where low throughput is needed, such as in the post-treatment of exhaust gases, this process would probably become a candidate to be considered.
