Abstract

PURPOSE: To obtain the titled gas without causing the corrosion of a device useful for an electricity generation system with high efficiency and low pollution, by desulfurizing a gas evolved from a gasification furnace and removing dust from it efficiently through a catalyst contact treatment of COS conversion, dry type dust collection, alkali treatment, wet type electric dust collection, etc.
CONSTITUTION: A gas produced from the gasification furnace 1 is subjected to heat exchange by the super heater 2, etc., made at 250W450°C, brought into contact with the active face A of a conversion catalyst by the oxidizing device 3 of carbonyl sulfide through a parallel flow process, and converted into hydrogen sulfide. The gas is then subjected to heat exchange by the economizer 4, made at 100W150°C, introduced into the dry type dust collector 5 so that dust is removed, the dust is fed through the line a to the gasification furnace 1. The gas is sent to the device 6 for washing with water and for cooling, brought into contact with an alkali solution by the desulfurizing device 7 so that hydrogen sulfide is removed, sent to the wet type electric dust collector 8 so that the dust is removed, and waste water from every device is sent through the lines g, h, and i respectively and treated by the device 9 for treating the waste water.
