Alfa Laval - Coke oven gas plant

Traduire cette page

Coke oven gas is an abundant by-product of coverting coal into coke used in steel production. But the impurities it contains make it unsuitable for use as fuel or feedstock. To reduce costs, improve yields and treat gas in an environmentally responsible way, Alfa Laval provides highly efficient solutions for refining – from primary gas cooling to light oil processing.
