Reducing energy consumption and CO2 emissions of Coke Plant

Abstract

The efficient energy use of Coke Oven Plant is considered in this paper. The main objective is the reduction of energy consumption and reducing CO2 emissions per production unit by use of waste heat for various needs of production site demands. The considered process consumes the external hot utilities 25.4 MW and cold utilities 24.9 MW. The use of waste heat for district heating and hot water supply allow reducing the external cold utilities by 23.5 MW. This heat can be used for heating of 1,869,825.6 m3 in apartment buildings, municipal facilities, shopping malls and etc. The use of waste heat from flue gases for electricity production allows obtaining additionally about 7.5 MW of power that can be utilized for production needs and exported outside. The provided case studies show the pathway for an efficient retrofit of coke production and most profitable ways for investment.
