PROCESS FOR PRECOOLING RAW COKE-OVEN GAS AND FOR DESORBING COKING WASHES AND CONDENSATES

摘要

The present invention relates to a process for the crude gas precooling of coke oven and for the desorption of water, ie washing water and condensate from the coke oven using hot coke oven gas. According to the invention, a) the pre-cooling the refrigerated raw gas directly into the collecting container to approximately the water vapor saturation temperature is preferably entirely, but at least to above the dew point naphthalene between approx. 30 and 50, against the flow of condensate formation, ie with a gas stream from bottom to top and b) desorbing the water between the collecting vessel and precooling outlet are exchanged against the current with the raw gas.
