In hydroprocessing applications, the Reactor Effluent Air Cooler is one of the most critical components in the high-pressure recycle gas loop.
REAC units operate in challenging conditions where ammonium bisulphide and ammonium chloride precipitation, pressure drop, corrosion and erosion-corrosion must all be considered.
Selecting the correct air cooler type, metallurgy, fabrication approach and NDT regime is therefore essential. Therco Serck has delivered REAC bundles in carbon steel with plugged headers, as well as high-nickel alloy designs with pipe manifold headers.
