Heat recovery from the crude and hot coke oven gas by oil or tar quenching
Almost one third of the coking energy is transformed into detectable heat in the crude and coke oven gas rising through the ascension pipe. It is recovered industrially by indirect exchange by means of a liquid heat carrier. In this ECSC project, the oil quenching technique has been simulated at the 400 kg coking oven scale, after preliminary heat calculations. The quenching section, having been designed and implemented, not only confirmed the recoverability of the heat energy by tar or oil, cooled and recycled, acting as a heat carrier, but in addition showed qualitatively the benefits of selective condensation of the organic products (benzols, phenols, tars) and water. Supporting experiments were carried out on the primary condensers and on a benzol scrubber.
