Abstract
A system includes a heat exchanger including a first channel having a syngas flow path and a second channel having a slurry flow path. The heat exchanger, when in operation, causes a heat transfer from a syngas along the syngas flow path to a slurry along the slurry flow path. The heat transfer causes heating of the slurry from a first slurry temperature to a second slurry temperature and causes cooling of the syngas from a first syngas temperature to a second syngas temperature.
Claims20
A system, comprising:
- a heat exchanger, comprising
- a first channel having a syngas flow path;
- and
- a second channel having a slurry flow path, wherein the heat exchanger, when in operation, causes a heat transfer from a syngas along the syngas flow path to a slurry along the slurry flow path, wherein the heat transfer causes heating of the slurry from a first slurry temperature to a second slurry temperature and causes cooling of the syngas from a first syngas temperature to a second syngas temperature.
A system, comprising:
- a controller having a processor, a memory, and instructions stored on the memory and executable by the processor, wherein the instructions comprise:
- temperature control instructions to control a heat transfer in a heat exchanger from a syngas along a syngas flow path to a slurry along a slurry flow path;
- and
- contamination detection instructions to detect a slurry contamination of the slurry with the syngas or a syngas contamination of the syngas with the slurry.
A method, comprising:
- receiving a slurry at a first temperature through a first inlet of a heat exchanger;
- receiving a syngas at a second temperature through a second inlet of a heat exchanger, wherein the second temperature is higher than the first temperature;
- and
- exchanging heat from the syngas to the slurry through the walls of the heat exchanger to heat the slurry to a third temperature.
