COG is either used as fuel in combined cycle power plant [9-11], for methanol synthesis [12, 13], for natural gas synthesis [14], or as a source of H2 through extraction [6, 15]. Coke gas is a by-product of industrial coke production from pit coal, coke gas is created by high-temperature dry distillation of coking coals in the absence of oxygen. 0000041710 00000 n h�261�P0P���w�/�+Q0���L)�66�0 0000008964 00000 n heat exchanger positions in the coke oven gas (COG) cleaning process, causing high maintenance costs and bus m. or ecna mf pr el aopti Alfa Laval is one of the world’s leading suppliers of heat exchangers.

Flushing liquor is formed from the cooling of coke oven gas and it contains tar. Coke Oven Gas Renaissance of a fuel In the 19th and the first half of the 20th century coke oven gas was one of the main sources of energy for urban households. coke-oven gas, as a rule, it is no more than 2.5 kPa. 0000013399 00000 n At the same time, there is 7 × 1010 m3 coke-oven gas (COG) produced in coke plants annually in China. h޴Vmk�0�+�E��fA $m� �2��J?h�I�luk��t��*Y��n�\t���yNI�ĸV�V�h.Aa�i�Bg>$GB)�0���4����R��5�BQpf(#���ip��9���ۦݘ 0000029710 00000 n Typically, coke-oven gas is obtained from a battery comprising a number of narrow, vertical chambers, or ovens (0.5m wide, 5m high and 12m long) built of silica brick that are separated by heating ducts, such that heat is transmitted to the coal through both sides of the chamber walls. startxref 159 0 obj<> endobj 0000003241 00000 n Combusted gases collect in a common tunnel and exit via a stack which creates a natural draft in the 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.

The evolved coke oven gas leaves the coke oven chambers at high temperatures approaching 1100 deg C. This hot gas is immediately quenched by direct contact with a spray of aqueous liquor (flushing liquor).
