摘要
The present process is directed to the cooling and cleaning of hot crude synthesis gas leaving a gas generator (solid hydrocarbon gasification reactor) wherein the hot crude synthesis gas leaving the top of the gas generator in an upflow direction is quenched by injection of cold purified synthesis gas. The gas velocity is then reduced and the gas stream is reversed in a downflow direction whereupon the gas velocity is increased again. The gas stream is again reversed in an upflow direction and the gas velocity is decreased whereafter the gas is indirectly cooled and flyash is separated therefrom.
