Abstract
A process and system for cooling syngas provides effective syngas cooling and results in reduced levels of fouling in syngas cooling equipment. A process for cooling syngas includes blending syngas with cooled recycled syngas in an amount effective for providing a blended syngas with a temperature at an inlet of a syngas cooler of about 600° F. to about 1400° F. The blended syngas changes direction of flow at least once prior to the inlet of the syngas cooler.
Claims29
A process for cooling syngas, the process comprising:
- blending syngas with cooled recycled syngas in an amount effective for providing a blended syngas with a temperature at an inlet of a syngas cooler of about 600° F. to about 1400° F.,
- wherein the blended syngas changes direction of flow at least once prior to the inlet of the syngas cooler.
A syngas mixing system comprising:
- a gasification chamber having a diameter DH;
- a syngas recycle inlet having a diameter DC, the syngas recycle inlet entering the gasification chamber at a distal end of the gasification chamber;
- and
- a gasification outlet having a diameter DM, the gasification outlet continuous with the distal end of the gasification chamber, the gasification outlet including at least one change of direction prior to entering a syngas cooler.
