Columns, Strippers & Scrubbers

Custom fabricated stainless steel strippers & scrubbers

SFI builds stainless steel stripper and scrubber columns that are used to filter/remove VOC's (volatile organic compounds) from liquid or vapor stream and we provide them to any level of integration required.  We do not engineer the process, but based on customer specifications, SFI will provide:

  • Stand-alone units with fully welded internal supports, ready for field installation of customer furnished internals
  • Complete integrated assemblies with bed limiters, packing supports, sieve trays, mist eliminators and internal packing

Our 35 years experience building stainless equipment for customers across numerous industries has given us the knowledge and skills necessary to fabricate high quality vessels such as these.  Stripper and scrubber columns share many design elements similar to the pressure vessels, mixers and storage tanks we build:

  • ASME designed and stamped pressure vessels
  • 300 series stainless or nickel alloys such as hastelloy or 2205 duplex
  • Manways
  • Sight glasses
  • Insulation rings, vacuum rings
  • Skirt supports
  • Shop or field fabricated

Below is a sampling of stainless steel columns built by SFI for customers in various industries.
