Title: Selective removal of dust or tar type substances from gases - to facilitate and improve desulphurising of coking and reactor gases
Inventor: HOELTER HEINZ
IPC: C10K1/20
Filed: 1977-01-27
Abstract: Gases containing and/or able to form dusty, tarry and/or resinous material sas well as salts at temps. between 25-1,000 degrees C are cleaned selectively by passing them through a loosely stacked mass of inflated, sharply edges particles, esp. perlite, with a granular dimension of 2 to 5mm. For pref. the moisture content of the mass is 15% and its pH value is about 4. The insertion of a cleaning column with perlite, through which the gas flows at around 100 mm/sec, makes it possible to remove large quantities of polymerisable material, with tar, dust, etc. The absorption of hydrogen sulphide in the iron oxide of the fine cleaning column, is thus increased by 50% and the mass can be emptied and cleaned more easily. The plant can be installed behind a high pressure coal gasifying reactor, and coke oven gases can be desulphurised at low pressure when the heavy hydrocarbons have been removed by this process instead of by electrical gas cleaning.
