A petrochemical company, as part of its manufacturing process, will utilize four steam-heated drum cabinets to heat material to 200°F (93°C) prior to mixing and blending with other ingredients. Supplied by Lewco Inc., each cabinet can hold up to 32 55-gallon drums and is heated using live steam.
The heating process transfers energy into the drum much faster than traditional convection heating. The live steam condenses on the outside surface of the drums and gives off energy directly into the drum when the steam changes to liquid. The cabinet’s stainless steel construction helps minimize the live steam from escaping and keeps condensate leakage to a minimum.
The temperature of the cabinets is controlled by the steam pressure and a thermocouple-actuated modulating control valve.
