Utilizing Hot Condensate/Flash Steam for Auxiliary Heating

From Therm-Omega-Tech, Inc.
 

 
THERM-OMEGA-TECH's HAT/MIX valves can be used to provide a convenient, economical, reliable and effective hot water tracing system. Steam and water supplies are all that must be connected to the valve. At an eastern specialty chemicals plant, it was required to maintain formaldehyde lines at about 100°F. Lower temperatures would affect product quality, while higher temperatures would cause the formation of formic acid and other undesirable side products. The solution was to install THERM-OMEGA-TECH's HAT/MIX-100 and HAT-100 valves which together provide both temperature control and backup safety high limit control. Approximately 100 psig steam and 50 psig water were piped to each HAT/MIX valve. The outlet from the valve then supplied the 3/8" tracer lines on various formaldehyde process piping. At the end of each tracer line just before connection to the return system, a HAT-100 valve was installed. After the system was started-up, the water temperature at the outlet of the HAT/MIX was approximately 100°F, exactly as the system design specified.
