摘要

The Statoil-Linde LNG Technology Alliance, established in 1996, reflects the LNG industry’s desire for reduced cost and schedule for the development of base-load LNG plants. In May 1997, the Statoil-Linde LNG Technology Alliance decided to install an industrial scale prototype of a spiral wound heat exchanger (SWHE) for liquefying natural gas in parallel to the existing plate-fin heat exchanger Cold Box of the NG liquefaction plant built by Linde in the PetroSA GTL Refinery (former Mossgas Refinery) in the Republic of South Africa. rnThe PetroSA facilities comprise an LNG plant with a nameplate capacity of 13.5 tons per hour using a single-flow mixed refrigerant cycle consisting of nitrogen, methane, ethylene and isobutene for the liquefaction of natural gas. rnRigorous LNG process- and heat exchanger models have been developed both by Linde and Statoil during several years, and these formed the backbone of the data acquisition and analysis. A test program was established to demonstrate the mechanical integrity during several tests as well as the correctness of the thermal, hydraulic and geometrical design for different operation scenarios. rnMajor emphasis was put on the scientific analysis to verify design tools for thermal and hydraulic design of SWHEs based on high quality operational data. The tests and analytical results, from two test periods in 1998 and 2001 and a continuous involvement of the heat exchanger in daily operations at the facility, provides an extremely comprehensive database. rnLogging of more than five years of daily operation with frequent start ups and shut downs with quite high temperature gradients has proven mechanical integrity.
