Condensation corrosion in gas phase areas of High Pressure Equipment and Piping systems plays a significant role in the safety and reliability of urea plants. Industry practice has proven that 9-bar steam tracing with typical insulation is inadequate to avoid condensation corrosion. This is especially evident at heat sinks such as lifting trunnions, supports, platforms thermowells, Tee’s, weldolets, etc.
More attention and additional measures are required to avoid condensation corrosion and to assure safety and reliability. Controls Southeast Inc. provides engineered heating solutions to specifically address these risks, resulting in a higher safety standard, higher reliability and a longer lifecycle. This paper is presented at the Nitrogen & Syngas Conference 2013 in Berlin.
