PURIFYING AND COOLING COAL GAS

摘要

Apparatus for purification of synthesis gas produced by coal gasification is provided with a vertical gas distribution chamber which is internally pressurized and within which the synthesis gas leaving the reactor is cooled. The chamber is formed with a gas take-off line which opens into the gas distribution chamber and extends therefrom at an angle, the gas take-off line leading to a serially connected waste heat boiler. A coolant bath is contained in a lower portion of the gas distribution chamber and a heat exchanger is formed in this lower portion by tube coils which are arranged in the wall of the distribution chamber defining the lower portion.
