  • Tar recovery from gasification of a carbonaceous feedstock
    Patent number: 9051517
    Abstract: A method (100) of recovering tar from the gasification of a carbonaceous feedstock includes gasifying (12) a carbonaceous feedstock (14) to produce a raw gas (20) which includes at least CO, H2, tar and entrained solids, the raw gas (20) being at a temperature of at least 250° C. and a pressure of at least 15 bar (g). The raw gas (20) is quenched and washed (22) with a quench liquid (24) producing a solids-containing liquid stream (32) which includes tars, the solids-containing liquid stream being at a temperature of at least 150° C. and a pressure of at least 15 bar (g). Solids (56) are separated (46) from the solids-containing liquid stream (32) to provide a tar recovery stream (102). The tar recovery stream (102) is treated by at least cooling (34) and pressure expansion (36) thereof to produce a tar stream (58).
