Pre-Packaged Heating System
Application:
Chemical processing plant required a complete temperature control module for processing of specialized lubricants. A safe method of heating a 4000 gallon Pfaudler glass lined jacketed vessel was require to heat product to 310°F.
Upon an exothermic reaction the process needed to be maintained at 325°F for 3.5 hours, then cooled to 210°F.
A steam jacketed system was rejected due to potential damage to the glass lining. The transition between heating and cooling was also troublesome.
Solution:
A Pick steam injection water heater was incorporated to provide jacket temperature up to 316°F. 80 psig back pressure was applied to the hot water loop to keep the process in liquid state, providing even and uniform jacket temperature. Process temperature was controlled so not to exceed rating of the glass-lined vessel.
A cooling valve was incorporated in the system to allow for “metered out” cooling of the jacket during the exothermic stage of the process and for final cooling. As the valve opened, hot water discharged the loop, allowing for cool make up water to enter.
A secondary Pick heater body was installed as an after-cooler, blending cold water make up to blend with discharge. This eliminated the flash that would have otherwise occurred as 316°F water was metered from the system. Blended water controlled at 150°F was returned to the cooling tower.
Features and Benefits:
• Accurate Temperature Control
• Fully Automatic Operation
• Compact Design
• Smooth Transition from Heat to Cool
Why Choose Direct Steam Injection for Chemical Processing?
Chemical manufacturers rely on precise temperature control to maintain product quality and process consistency. Pick Heaters' direct steam injection systems provide instantaneous heating, accurate temperature control, and efficient energy transfer for a variety of chemical processes. The technology helps reduce processing time, improve operational efficiency, and support reliable performance in demanding industrial environments.
