- W2591938758 abstract "Modern oil and gas processing plant comprise a complex arrangement of piping and equipment with many interfaces between the overall design and packaged equipment, as well as the commissioning and operations teams during design and start-up. Notwithstanding the efforts and planning of these teams, a number of start-up problems in new facilities inevitably arise. The key objective of the commissioning team is to complete start-up to schedule, often resulting in a number of shortcomings left for operations to resolve later. This paper presents two case studies which demonstrate how an understanding of process systems and a rigorous analysis of available site information resolved such start-up problems. In the first case an unnecessary design constraint on a gas plant's low temperature separator resulted in hydrating in the relief header during the initial plant start-up. In a further case less than 50% of the design hydrogen recovery rate from the de-ethaniser overheads in an ethylene plant was achieved from plant commissioning in spite of significant plant rectification works. Analysis of plant data over a number of years failed to identify a simple piping design error by the process licensor even though plant field data was available, which was consistent with the incorrect piping line-up. In these two cases following analysis and relatively minor modifications the plant was able to operate as originally intended, in the second case after 5 years of operation at sub design hydrogen recovery." @default.
