The hot raw synthesis gas stream leaving the reaction zone of a free flow partial oxidation gas generator at a temperature in the range of about 1800°to 3000°F. is passed through a first gas diversion and residue separation zone where the velocity of the gas stream is reduced and its direction is diverted into a side transfer line. Solid material and molten slag separate by gravity from the gas stream. The hot gas stream is then introduced into a second gas diversion and residue separation zone where the direction and velocity is changed and additional residue is separated. About 0.5 to 20 vol. % of the hot gas stream may be passed through bottom outlets in said first and second gas diversion zones in order to prevent bridging. The hot gas stream from the second gas diversion zone is passed upwardly through a radiant cooler where additional solid matter is removed by gravity and the gas temperature is reduced to a temperature in the range of about 900°to 1800°F. In this embodiment, the second diversion and residue separation zone comprises a plurality of high temperature resistant thermally insulated cyclones connected in series or in parallel. Entrained solid matter and slag are removed from the gas stream by means of said cyclone separators without substantially reducing the temperature of the gas stream.

A process for separating entrained solid matter and slag from a hot raw gas stream comprising H2, CO, CO2, entrained solid matter and slag, and one or more materials from the group H2O, H2S, COS, CH4, NH3, N2, and A as produced in the reaction zone of a gas generator by the partial oxidation of soli
A process for separating entrained solid matter and slag from a hot raw gas stream comprising H2, CO, CO2, entrained solid matter and slag, and one or more materials from the group H2O, H2S, COS, CH4, NH3, N2, and A as produced in the reaction zone of a gas generator by the partial oxidation of solid carbonaceous fuel at a temperature in the range of about 1800°to 3000°F. and a pressure in the range of 10 to 190 atmospheres, and cooling said hot raw gas stream comprising: (1) passing said hot raw gas stream directly from said reaction zone downward through a connecting passage at high velocity into a thermally insulated unobstructed free-flow gas diversion and residue separation chamber where the velocity of the gas stream is reduced, said residue separation chamber having a net internal volume which is smaller than that of said reaction zone and having bottom and side outlets, separating by gravity a portion of said solid matter and slag from the gas stream without substantially reducing the temperature of the gas stream, and passing said portion of separated material by gravity through said bottom outlet into a first slag pot located directly below said first gas diversion and residue separation chamber; (2) passing about 80.0 to 100 vol. % of the hot gas stream from said first gas diversion and residue separation chamber with a portion of said solid matter and slag removed through said side outlet then through a thermally insulated transfer line and then through a plurality of thermally insulated cyclones connected in series, parallel or both, said cyclones having inlet means and upper and lower outlet means and being located in a separate vertical pressure vessel from that containing said gas diversion and residue separation chamber, separating additional solid matter and slag from the gas stream by said cyclones without substantially reducing the temperature of the gas stream, and passing said separated portion of material into a second slag pot located directly below the cyclones; (3) passing about 80.0 to 100 vol. % of the hot gas stream with a portion of said solid matter and slag removed by said cyclones directly into the bottom of and upward at a reduced velocity through the unobstructed central vertical passage of a radiant cooling zone having a plurality of vertical tubes lining the inside walls, simultaneously cooling said upflowing hot gas stream to below the maximum safe operating temperature for a downstream energy utilizing means by indirect heat exchange with a coolant flowing in said vertical tubes and at least partially solidifying any remaining ash particles in the gas stream, and removing additional solid matter and slag from said gas stream by gravity, and passing said separated portion of material into said second slag pot; and (4) removing a cleaned gas stream from said radiant cooling zone at a reduced temperature.
