Feasibility Study for a Petroleum Coke and/or Coal-Gasification Project

摘要

Cities Service Company (CSC), Gulf States Utilities (GSU), and Stone and Webster Engineering Corporation, with the assistance of Texaco Development Corporation and Beard Engineering, Inc., have performed a preliminary feasibility study for a petroleum coke and/or coal gasification project based on a commercial Texaco liquid feed gasification system for application in the Lake Charles, Louisiana area. The technical feasibility of an energy conversion system designed to allow sequential switching from liquid to solid hydrocarbon feedstocks or to use various hydrocarbon feedstocks, such as vacuum residue, petroleum coke, and coal, in a single gasification system has been confirmed and a decision has been made to continue with the development of a project plan based on the use of lower grade hydrocarbon feedstocks and/or coal to generate additional electricity or to replace a portion of the present liquid and gaseous fuel requirements of Cities Service and Gulf States Utilities. The study addressed a number of basic concerns related to the planning of such a project, including a review of the projected energy needs of CSC and GSU, an assessment of the availability of feedstocks, selection of a preferred energy conversion plant design and site, a preliminary cost estimate of the proposed energy conversion plant, and a review of environmental and licensing considerations. In addition, as a point of reference, a technical and economic update was prepared of the Louisiana Municipal Power Commission (LAMPCO) Project, which is a proposed 115 MW conmbined cycle power plant based on a commercial Texaco gasification system using vacuum residue. The results of these evaluations are discussed. (ERA citation 07:045522)
