One of the world’s leading producers of high purity quartz sands (which are the raw materials of choice for the production of fused quartz crucibles, semiconductor quartz ware, and quartz lighting products) needed a solution to control the amount of highly concentrated HCL fume emissions being generated by the processes at their facility.
KCH Services, Inc. Engineered Services located in Forest City, North Carolina was given the task of providing a state-of-the-art solution needed to control the extremely high concentrations of HCL emissions being generated from this process. KCH engineers developed a multi-stage, counter current, vertical flow fume scrubber control system that would provide the required efficiencies needed for this type of aggressive acid. It was decided that a system which included a vertical cyclonic pre-control unit, followed by a wet fume scrubber with a total packing height of 14’-0”, and a final Fiber Bed mist eliminator would be the best design to meet the required emission rate. Due to height restrictions at the facility the fume scrubbers had to be designed into (3) different vessels, stage # 2, stage # 3, and stage # 4, with a pre-control stage and final post control stage.
