Mercury Control

Selective Catalytic Reduction (SCR)


Whether you are buying or managing catalyst, assessing or installing SCR, or actively operating an SCR, W.S. Hinton & Associates can help.

Our significant experience within the U.S. in the design, operation, testing, and maintenance of SCR reactors can aid you in the purchase of an SCR reactor and catalyst, which optimizes NOx reduction with a minimum of downstream problems developed by ammonia slip. We have ongoing working relationships with various catalyst manufacturers including, Cormetech, Hitachi America, Johnson Matthey and Haldor Topsoe.

Our testing partners have capabilities which include the full range common to SCR testing as well as other specialized tests. Analyses such as ammonia distribution, ammonia slip, NOx reduction, etc. can be very difficult if the intricacies of the testing are not recognized. Our experience prevents these mistakes, allowing for accurate results the first time. We design and perform acceptance and performance tests to ensure maximum NOx reduction at a minimum cost.

We also have experience in catalyst development, and have worked with various firms to develop proprietary catalytic products for use in the pollution control industry.
