Reapplication Of An Induction Steam Turbine To Extraction Cogeneration Service.

LecturePg. 77-84Reapplication of used power equipment can shorten project schedule and decrease capital cost significantly. The following is a broad overview of the reapplication of an FCC airblower steam turbine to 15 megawatt cogeneration service in B.P. Chemicals, acrylonitrile plant in Green Lake, Texas. The turbine, an Elliott 2NV9 with 40 psig induction, was originally installed in a Louisiana refinery in 1965. A 1982 refinery revamp left this equipment mothballed in place until March 1988, when it was purchased by B.P. Chemicals. This turbine was then salvaged and modified to meet a new operating requirement, 55 psig extraction instead of 40 psig induction. This project was developed and managed by plant engineering at the Green Lake plant. The development, reapplication, remanufacturing, and startup phases of the steam turbine generator are documented. Contributions from the OEM, after market suppliers, and independent consultants were vital to the project's success. Measures taken to ensure the performance of the contractors and confidence in the reliability of the end products are described
