Chinese company to convert coke oven waste gas into power for region with three GE aeroderivative gas turbines
06 January 2011
Jiangsu Tianue Energy & Chemical Group Co. Ltd is building a high-efficiency gas turbine power plant to utilize coke oven gas (COG) into power and steam to meet increasing energy needs in its region. The power plant will be equipped with three GE aeroderivative gas turbines, which are the first LM2500+G4 units sold in China.
GE’s innovative technology allows us to turn a previously environmentally harmful gas into a useful tool to produce energy for our customers. In addition, we will be able to reduce CO2 emissions by 300,000 tons per year and supply stable electricity to Pei County.
—Teng Daochun, chairman, Jiangsu Tianue Energy & Chemical Group Co. Ltd.
COG is a byproduct of the coking manufacturing process. GE claims that among all of the current treatment methods, its solution is more reliable, cleaner for the environment and uses the residual energy at a higher efficiency rate. GE also is providing a 12-year services agreement with one spare engine to ensure maximum operability at the new plant.
Using our aeroderivative technology for low-calorie, coke-oven gas is a technology breakthrough, and this project is another example of GE’s commitment to invest in progressive solutions to meet environmental challenges throughout the world. Through this endeavor, GE and Tianue are responding to the Chinese government’s call to reduce greenhouse gas emissions by conserving energy and making contributions to a cleaner economy in the country.

On 9 November 2010, GE announced plans to invest more than $2 billion into its efforts in China through 2012 to help tackle the country’s pressing energy and infrastructure needs. GE Chairman and CEO Jeff Immelt announced that the company plans to commit $500 million to enhance China R&D capabilities and establish new Customer Innovation Centers to better serve west, north, central and south China.
Jiangsu Tianue Energy and Chemical Group Co. Ltd. is a large and advanced private enterprise group, dealing mainly in coal washing, coking, power generation, coal-gas supply, mining, etc. Formerly known as Xuzhou Huanyu Molybdenum Industry, it is the first Sino-foreign joint venture in Xuzhou. It has passed ISO9002 quality system authentication, gained coking industry access in 2008 and also passed OHSMS occupational health and safety management system authentication.
GE has listed coke-oven gas in its gas turbine literature for as long as I've been reading it. I have to wonder if this is the first application, or just the first in China.

Yes, GE has been making liquid fuels and gaseous fuels heavy duty turbines since the early 1950s. This could not be their first coke oven waste gas installation. GE's heavy duty gaseous fuels turbines are tunned for various types of gaseous fuels and have been improved during the last 5+ decades. The model been installed in China may have a few added features to match the specificity of the gaseous fuel available.
Also, it could be part of the PR campaign to sell those turbines to China.
