GE To Provide Stewart & Stevenson With LM6000 Fueled by Naphtha Cracking Process Byproducts at Japanese Plant
DALLAS, Texas - GE Marine & Industrial Engines (M&I) announced it has secured a contract with Stewart & Stevenson International, Inc. to provide one LM6000 aeroderivative gas turbine-generator, M&I reported today at Power-Gen International '97. The unit will burn a combination of methane and hydrogen fuel which are byproducts from the naphtha cracking process at Tosoh's petrochemical plant in Yokkaichi, Japan.
This is a unique application for the 42-megawatt LM6000 because of the fuel it will burn as well as the captive power scheme. Tosoh is expanding its Yokkaichi facility which currently has 13 cracking furnaces that burn an externally introduced fuel to produce 400 tons of ethylene per year.
The expanded plant will feature an unusual gas turbine-based integrated simple-cycle configuration. The electrical power generated by the gas turbine will be used in the existing plant as well as for the expansion. The exhaust heat from the gas turbine will be used for a new naphtha cracking furnace, and will minimize the supplementary fuel required for the furnace. Total plant capacity will increase 25% to 500 tons of ethylene per year.
The LM6000 was manufactured at M&I's Evendale, OH manufacturing facility, and Engineering & Shipbuilding, Tokyo, Japan, contracted with Stewart & Stevenson through Sumitomo Corporation as the importer, for the LM6000 gas turbine package. Mitsui will also be responsible for the engineering, procurement and construction of the power generation portion of Tosoh's naphtha cracking plant expansion. Lummus and TEC will carry out the engineering and construction for the remainder of the plant expansion.
Stewart & Stevenson expects to deliver the LM6000 package to the Yokkaichi site in late 1998, and commercial operation of the LM6000 is slated for March 1999.
