Closed final gas cooling systems save energy and eliminate emissions at coke plant

Avdeevskiy coke processing works is Ukraine’s leading coke processing plant. To comply with European emission and process regulations for the coke industry, the plant has replaced two open final gas cooling systems,using scrubbers, with Alfa Laval closed systems utilizing 11.5 metre high spiral heat exchangers (spiral columns).

Upgrading the desulphurization department

Prior to the installation of the new systems, the coke oven gas (COG) was scrubbed and cooled in an open system using water. This arrangement resulted in considerable emissions of harmful substances to the atmosphere from the cooling towers.

After hearing about Alfa Laval’s technical solution, Avdeevskiy coke processing works decided to install closed final gas cooling systems in the desulphurization department.


The all-round heat transfer solution. Exceptional compactness and self-cleaning design make Alfa Laval spiral heat exchangers extremely versatile. Ideal for everything from dirty fluids to high vacuum condensation.
