Abstract [en]

Eco-industrial parks (EIP) are clusters of industry corporations that collaborate with reusing waste and energyefficient use of resources with no or minor impact on the environment. This paper presents a case study that examines the feasibility of using gas turbine technology in one industrial park, located in Dongguan city of Guangdong province in China.

A model of a gas turbine based combined heat and power (CHP) plant with a heat recovery steam generator (HRSG) for absorption cooling was developed and simulated. A steam-injected gas turbine (STIG) has been selected in the system to increase electricity production while generating steam. The study includes performance analysis of the cogeneration plant in terms of thermal efficiency, cost estimation, and greenhouse gas emission. The gas turbine based cogeneration system has been compared to a baseline reference case that is defined as if all energy to the industrial park is supplied from the local electricity grid. The results show that the gas turbine based cogeneration system can reach a thermal efficiency of 58 % and reduce the CO2 emissions with 12,700 tons per year. A sensitivity analysis on the costs of the system has also been made based on fuel costs and interest rate which shows that the investigated system is economically profitable at natural gas prices below 4.4

yuan/m³ with fixed electricity prices and at electricity prices above 736 yuan/kWh with fixed natural gas prices. The sensitivity analysis based on interest rate showed that the proposed system is economically feasible with interest rates up to 16 %.
