Title:
GASIFIER INJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/056334
Kind Code:
A3
Abstract:
The present invention relates to an improved gasifier injection system. In particular, the present invention provides an improved apparatus and operating scheme to improve the control flow of solid particulates in a multi-burner gasifier. The system also provides for integrated flow control and emergency shutoff in the case of abnormal operating conditions or unexpected backflow of the process burners. This improved design simplifies the mechanical systems required for large multi-burner gasifiers thus providing a more reliable and compact gasifier feed system. In preferred embodiments, the gasifier hydrocarbon feed is substantially in a solid particulate state and is preferably comprised of coal, petrochemical coke, and/or solid biomass.
