With its contribution to acid rain and the formation of fine particulate matter, the removal of SO2 continues to be one of the most important environmental issues and financial challenges facing the coal-fired power industry and coal-fired boiler operators worldwide.

With tightening National Ambient Air Quality Standards (NAAQS), the Cross-State Air Pollution Rule (CSAPR), Regional Haze, and Europe's Directive on Industrial Emissions 2010/75/EU (IED), the power industry is demanding cost-effective, "Best Available Technologies"  for SO2 control. Many are evaluating upgrading the performance of existing flue gas desulfurization (FGD) processes, a switch to the use of a lower sulfur coal, the addition of new scrubbers, or potentially having to retire electric generating units.

Since the early 1970s, AECOM Process Technologies has been providing Engineering (E);Engineering and Procurement (EP); and Engineering, Procurement, and Construction (EPC) services related to design, optimization and implementation of SO2 removal technologies. We offer clients multiple alternatives for reducing SO2 emissions. The best fit is often site specific. We maximize the use of existing equipment and infrastructure to deliver the lowest cost solutions.
