Alternative metallurgies reduce the cost of amine gas treating units
International audienceProduction facilities, including platforms or FPSO, are becoming more and more complex structures. Reducing the weight of the process units is an important challenge, and represents a huge source of costs savings. IFPEN, PROSERNAT and INDUSTEEL have evaluated two alternative metallurgies with high mechanical properties to reduce the weight of equipment of amine gas treating units (AGRU). Duplex stainless steels are considered as an alternative to more conventional austenitic stainless steel grades. High strength alloy steel ASME SA-533 type E class 2, having an UTS above 90 ksi, can be an alternate to carbon steel ASME SA-516 Gr65 type (UTS 65 ksi). The compatibility of these steel grades with amine service was checked through autoclave corrosion tests in amine solutions. Various experiments were performed in conditions representative of the bottom part of absorber and of upper section of regenerator of AGRU, with variable loadings of CO 2 and H 2 S. Study used different specimens: weight-loss coupons, four-point-bend assemblies, and U-bends. For all these tests, alternative metallurgies proved to behave at least as well as the reference ones generally considered in amine plants with no significant corrosion nor cracking. In addition to experimental tests and presentation of steel properties, the paper describes a case study of AGRU where the mass gain and CAPEX benefits are elaborated for a 75 bar, 4.5 meters diameter absorber, and for a 4.8 meters diameter, low pressure, stripper
