IEC Fabchem - Vertical Bayonet Steam Heated
IEC vertical bayonet style vaporizers are high-quality chemical evaporation systems. They are versatile enough to be used for a variety of process liquids in a wide variety of plants, they come with the option of ASME U-stamp.
IEC FABCHEM has constructed over 500 vertical bayonet vaporizer systems for a wide ranging catalog of process fluids Some of the more common applications are:
- Ammonia
- Chlorine
- Tri-methyl amine
- Di-methyle amine
- Tri-fluoro acetyl chloride
- C3-C6 Hydrocarbons (including LPG)
- Carbon Dioxide
- Di/Trichlorosilane
- Alcohols
- Silicon Tetrachloride
- Sulfur Dioxide
IEC manufactures vertical bayonet style vaporizers using carbon steel, stainless steels, and speciality alloys such as Hastelloy B/C series and Inconel grades. The unique bayonet (tube in tube) construction provides some key benefits over horizontal type vaporizers.
- Anti-freeze safety. 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%.
- Low 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.
- Free tube expansion and contraction. Thermal stress is eliminated because tubes are only fixed at one end.
