Shell-and-tube heat exchangers, absorber columns, separators, and shop-fabricated ASME vessels and tanks for LNG gas treatment, liquefaction, and low-temperature process service.
The LNG process begins with pre-treatment of feed gas to remove impurities such as H₂S, CO₂, H₂O, mercury and heavier hydrocarbons, before cooling to cryogenic temperatures around −145 °C to −163 °C (−229 °F to −261 °F) for storage and transport.
Harris Thermal has fabricated equipment for LNG producers, EPCs and OEMs across that chain — the ASME-code exchangers, columns, separators and vessels the process requires, including Lethal Service and Cyclic Service designs per ASME Section VIII.
Harris Thermal fabricates pressure vessels and tanks for low-temperature service in our own shop and ships them complete. Design temperature drives the material, the impact-testing requirement and the weld qualifications, and all three come from the code and the project specification.
Field erection is outside our scope, so facility-scale field-erected LNG storage tanks are not equipment we supply. See our shipment planning for how equipment envelope and transportation are worked out early.
Low-temperature duty and contaminant-bearing feed gas pull in different directions, and the alloy has to answer both. See our materials and metallurgy capability and current certifications.
Shell-and-tube heat exchangers, process coolers and heaters, condensers, replacement exchangers and tube bundles, ASME Section VIII pressure vessels, separators and knockout drums, accumulators, process vessels, absorber and scrubber columns, custom shop-fabricated tanks within our scope, and stainless and high-alloy equipment for low-temperature service. Harris Thermal fabricates equipment for integration into LNG processing and handling systems; pumps, valves, instrumentation, controls and complete packaged systems are supplied by others.
Yes, within Harris Thermal's qualified shop-fabricated capabilities and subject to the project's design temperature and pressure, material, code, fabrication, testing and transportation requirements. Equipment is shop-fabricated and shipped complete; Harris Thermal does not perform field erection, so facility-scale field-erected LNG storage tanks are outside this scope.
Stainless steels including 304L and 316L, duplex stainless, AL-6XN, high-nickel alloys for contaminant-bearing streams, and carbon steel on structural and non-cryogenic duty. Low-temperature service brings its own impact-testing and weld-qualification requirements, and those follow the code and the project specification.
From liquefaction trains to facility upgrades, tell us the duty, the design temperature, and the code requirement.
