CREATIVE DEBOTTLENEKING PROJECT

摘要

United Gas Derivatives Company, UGDC, is an Egyptian joint venture company with equal ownership among BP, ENI and GASCO. UGDC owns and operates Natural Gas Liquids (NGL) extraction plant located at Port Said, Egypt. The facility receives gas from Mediterranean off shore concessions after passing through an on shore separation facility. The NGL extraction plant was originally designed for 1100 MMSCFD of feed gas. In view of the available feed gas from upstream facilities UGDC initiated a debottlenecking project to increase the capacity of the plant from 1100 MM SCFD to 1300 MMSCFD in a single train. The paper describes how the debottlenecking was achieved with a very low capital cost, although the initial study from an engineering contractor indicated requirements of major plant modifications and CAPEX spend of several millions of dollars. The paper details the investigations and analysis that were subsequently carried out in house which included some out of the box thinking. The result was that the increased capacity was achieved with minimum plant modifications. The paper contains interesting information on the successful debottlenecking at less than 10% of the original cost estimate.
