Increases in the value of petrochemical feedstocks often drive revamp projects to increase the capacity of NGL liquids plants that feed the petrochemical plants. A systematic approach involving definition of objectives, plant testing, plant modeling, modification evaluation, and final design has been successfully applied to NGL plant revamps. Definition of objectives includes determining the processing targets for future operation. Plant testing provides the basis of understanding the current limits. Modification evaluation incorporates both plant simulation and equipment design review to determine the revamp requirements. Final design integrates all aspects of the equipment and process changes to meet the overall objectives. This approach is detailed in a successful example in revamping a 500 MMSCFD (12,500 kNCMD) cryogenic gas processing plant to a capacity of 625 MMSCFD (15,625 kNCMD). The low-cost revamp was made without modification to the gas processing plant's compressors or expanders.
