Method for cleaning gas produced from solid carbonaceous material in a two-stage gas producer
This patent describes a method for cleaning gas produced from solid carbonaceous material in a two stage gas producer consisting essentially of the steps of: (a) passing second stage gas from the two stage gas producer through a first precipitator means to remove oil mist and particulates from the second stage gas; (b) passing first stage gas from the two stage gas producer through a cyclone means to remove particulates from the first stage gas; (c) cooling the first stage gas from the cyclone means; (d) mixing the cooled first stage gas and the second stage gas from the first precipitator means; while maintaining the temperature of the gas mixture at least at the temperature of the second stage gas; (e) cooling the gas mixture to a temperature in the range of about 25/sup 0/F to about 125/sup 0/F above the water dew point of the gas mixture; and (f) passing the cooled gas mixture through a second precipitation means to remove oil mist and particulates from the gas mixture and yield an industrial usable gas.
