A waste oil re-refiner in the Western United States will increase production to nearly 20 MM gpy. The state requires a direct fired heater to reduce SO2 emissions by 95%. Although packed bed scrubbers are common for this type of process, a vertical scrubber design can be expensive to retrofit into an existing facility. The facility was looking for a solution to meet or exceed emission standards and be relatively simple to install and maintain.
A case study is now available to describe how an Envitech high efficiency SO2 scrubber was used to solve this problem.
