HVM ASME, PED & CRN Demister Vessels, Mist Eliminators, and Knock Out Drums

HVM demister vessels effectively remove dry and liquid contaminants commonly found in vapor streams. When designing a demister vessel, operating pressures, temperatures, viscosities and liquid entrainment are important considerations. HVM engineers its demister vessels for effective separation across the board. HVM makes demisters of any size and shape from a wide range of materials.

HVM demisters achieve optimal removal of dry or liquid contaminants from gas streams.

  • Vertical and horizontal.
  • Internals designed to application.
  • Sizes to meet exact specification.
  • Carbon and stainless steel.
  • Internal and external coatings.
  • Skid mounting available.


Among other specifications, Houston Vessel Manufacturing’s design and fabrication of demister vessels, knockout drums and closed-drum tanks meets the following: Manufacturing certification to ASME, Section VIII, Division 1 and Division 2; PED (Pressure Equipment Directive); CRN and third-party certifications; i.e. ABS, DNV, BV.
