Tri-Mer packed bed scrubbers are ideal for the efficient removal of inorganic gases, odors, and fumes.
They are well-suited as primary or secondary systems in conjunction with thermal oxidizers, and are used in a series where there are multiple-contaminant gas streams.
Vertical Flow Scrubbers are suitable for chemical processes, metal finishing, semiconductor manufacturing and other industrial operations generating fumes and gases.
Optimum system performance is achieved with systems that combine intimate gas/liquid mixing and low pressure drop.
Design Considerations include:
Volumetric airflow rate through the srubber, generally expressed in cubic feet per minute (CFM). This is determined by the process to be handled by the scrubber, through information provided by customer and/or Tri-Mer analysis. System capacities range to 100,000 cfm and above.
Internal vs. external recirculation system, fan location in relation to tower, duct sizes, inlet and outlet, plus location of pump systems, tower access service ports, and service platform requirements all influence layout.
Standard construction materials are polypropylene, fiberglass and PVC. Optional materials include high alloy metals such as stainless and Hastelloy®. Dual-laminate structures incorporating FRP over PVC, PP, PVDF and Teflon® liners are available.
Removal efficiency of scrubber: inlet vs. outlet requirement, based on mass emission in lbs/hr. in vs. lbs./hr. out.
Factors to consider in calculating removal efficiency are:
Contaminant flow composition
Chemistry that will react with contaminants
HTU (height transfer unit) factors required for specified removal efficiency (packing depth)
Gas temp. - up to 2000°F with Q-Scrub quench option
