A quench system includes a housing having a longitudinal axis, a gas path for a gas within the housing, a steam input and output, and a dip tube within the housing. The dip tube includes tubing arranged to form a wall. A steam path, separate from the gas path, is disposed within the tubing in a thickness of the wall. The dip tube is configured to allow passage of the gas along the gas path. The steam input is fluidically connected to the steam output by the tubing. The quench system is configured to cool the gas along the gas path and heat steam along the steam path within the tubing of the dip tube.

The present application provides a gasifier for creating a flow of a syngas. The gasifier may include a reaction chamber and a quench chamber. The quench chamber may include a number of integrated scrubber trays therein such that the syngas first enters a quench pool via a dip tube and then passes through the scrubber trays before leaving the quench chamber.

Quench chamber with integrated scrubber system

A system includes a syngas cooler and a compatible seal gas system. The syngas cooler may be configured to cool a syngas. The compatible seal gas system may be configured to supply a compatible seal gas to a seal of the syngas cooler. The seal may be configured to block the syngas from a passage between an outer wall of the syngas cooler and a tube cage of the syngas cooler.

System and method for sealing a syngas cooler

A system includes a gasifier. The gasifier includes a reaction chamber configured to convert a feedstock into a synthetic gas, a quench chamber configured to cool the synthetic gas, and a transition section between the reaction chamber and the quench chamber. The gasifier also includes a quench ring configured to provide a first flow of a coolant to the quench chamber and a shielding gas system configured to provide a second flow of a shielding gas to protect at least one of the quench ring or the transition section.
