Patent ID: 8821598

Claim:
A system, comprising: a gasifier, comprising: a reaction chamber configured to convert a hydrocarbon feedstock, oxygen, and steam into a synthetic gas; and a quench chamber configured to cool the synthetic gas; a gas scrubber configured to remove contaminants and water from the synthetic gas; a synthetic gas transfer line from the quench chamber to the gas scrubber, wherein the synthetic gas transfer line is configured to transfer the synthetic gas from the quench chamber to the gas scrubber; a first water return flow line from a gas scrubber sump of the gas scrubber to a quench ring of the quench chamber, wherein the first water return flow line is configured to transfer a first flow of the water to the quench ring of the quench chamber; a second water return flow line from the gas scrubber sump of the gas scrubber directly to a quench chamber sump of the quench chamber, wherein the second water return flow line is configured to transfer a second flow of the water removed from the synthetic gas to the quench chamber sump of the quench chamber; and at least one pump configured to pump the first flow of water through the first water return flow line and configured to pump the second flow of water through the second water return flow line.
