Armstrong Chemtec vertical bayonet vaporizers are a superior general purpose vaporization option, versatile enough to be trusted in refineries and in the chlorine industry. Armstrong Chemtec is the only chlorine vaporizer manufacturer who is a member in both the Chlorine Institute and Euro Chlor.

Armstrong Chemtec has built over 4,500 vertical bayonet vaporizers for a wide ranging catalog of process fluids, with over 1,000 vaporizers in chlorine service. Some of the more common applications are:

  • Ammonia
  • C3-C6 Hydrocarbons (including LPG)
  • Carbon Dioxide
  • Chlorine
  • Di/Trichlorosilane
  • Methanol/Ethanol
  • Silicon Tetrachloride
  • Sulfur Dioxide

Armstrong Chemtec manufactures vertical bayonet vaporizers using carbon steel, stainless steels, and high nickel alloys. The unique bayonet (tube in tube) construction, developed by Armstrong Chemtec, produces a number of advantages over other types of vaporizing equipment:

  • Freeze Protection. Incoming steam (or other heating fluid) continuously heats outgoing condensate.
  • Superheat. Integral superheat capability may be provided.
  • Small Footprint. Vertical equipment occupies significantly less plot space than horizontal options.
  • Unlimited Turndown. The unit can operate at turndown approaching 100%.
  • Holdup Volume. The retained liquid volume is much smaller than alternative designs.
  • Capacity Control. The vaporization rate and liquid level are self regulating with downstream demand.
  • Unrestrained Tube Expansion & Contraction. Thermal stress is eliminated because tubes are only fixed at one end.
  • Removable Bundle. The tube bundle can be inspected and replaced easily in the field.

Armstrong Chemtec is the preferred vertical vaporizer supplier for multiple licensed refinery processes.
