摘要:
A process and apparatus are provided for gasification of a carbonaceous material. The process produces a raw syngas that can be further processed in a tar destruction zone to provide a hot syngas. The process includes contacting said carbonaceous material with molecular oxygen-containing gas in a gasification zone to gasify a portion of said carbonaceous material and to produce a first gaseous product. A remaining portion of the carbonaceous material is contacted with molecular oxygen-containing gas in a burn-up zone to gasify additional portion of the carbonaceous material and to produce a second gaseous product and a solid ash. The first gaseous product and said second gaseous product are combined to produce a raw syngas that includes carbon monoxide (CO), carbon dioxide (CO 2 ) and tar. The raw syngas is contacted with molecular oxygen containing gas in a tar destruction zone to produce said hot syngas.
摘要:
A process 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.
