Macrotek Successfully Commissions its Innovative SULFCAT® Gas Cleanup System

Global air pollution control provider, Macrotek Inc., announced successful start-up of its innovative SULFCAT® H2S removal system for a large landfill gas power plant in the Midwestern United States.

The system will be replacing a conventional chemical oxidation scrubber that was costly to operate. The landfill gas is being cleaned by Macrotek’s proprietary SULFCAT technology, an innovative process that efficiently removes Hydrogen Sulphide from a variety of industrial gas streams. SULFCAT uses a non-hazardous, regenerative reagent to remove H2S from industrial gas streams while minimizing operating costs.

One of the key benefits of Macrotek’s new H2S removal systems is the high degree of operating flexibility. The system will be capable of handling wide fluctuations in flow and composition.

The landfill gas entering the SULFCAT system contains levels of 4,000-6,000 ppm. The gas leaving the system is cleaned to levels well below the design range requirements of engines and is exceeding contractual design guarantees.

Macrotek engineers assisted to ensure a smooth commissioning process in June 2019.
