Benefits of technology

[0009]A process is provided for producing syngas that is effective for use in downstream processes. The process for producing syngas includes operating a gasification apparatus in a start-up mode until the gasification apparatus and equipment downstream of the gasification apparatus are adequately warmed up to a first target temperature.

Problems solved by technology

However when carbon monoxide is cooled, carbon monoxide may oxidize into carbon dioxide, and produce carbon (graphite) that precipitates as soot:
This reaction is generally known as Boud

Solid Load of Syngas Produced by Gasification in Production Mode

[0061]The gasification apparatus was operated in a start-up mode by providing carbonaceous materials to the gasifier at a feed rate of about half as much as that used in a production mode. Oxygen was supplied to the gasifier at a feed rate of about 40 to 50 lb-mole ton of carbonaceous material on a dry basis. As described previously, some air leakage into the gasifier was allowed that increase oxygen availability.

[0062]Upon starting up a gasifier under start-up mode as described above to obtain a first target temperature in a range of about 700° C. to about 1000° C., a carbonaceous material feed rate was increased into the gasification apparatus. A molecular oxygen containing gas was supplied to the gasification apparatus at the rate of about 50 to about 90 lb-moles per ton of water-free carbonaceous material. The gasifier was also fed a stream of carbon dioxide at the rate of about 10 to about 15 lb-moles per ton of wa...

Abstract

A process is provided for producing syngas that is effective for use in downstream processes. The process for producing syngas includes operating a gasification apparatus in a start-up mode until the gasification apparatus and equipment downstream of the gasification apparatus are adequately warmed up to a first target temperature. Upon reaching a first target temperature, the process is then operated in a production mode to produce a second syngas with a higher CO/CO2 molar ratio. Operation in a start-up mode until reaching a first target temperature, provides a process that is effective for reducing fouling in downstream equipment and for providing a second syngas can be more effectively cooled and cleaned.

Description

[0001]This application claims the benefit of U.S. Provisional Application Nos. 61 / 516,646, 61 / 516,704 and 61 / 516,667 all filed Apr. 6, 2011, all of which are incorporated in their entirety herein by reference.[0002]A process is provided for gasification of carbonaceous materials to produce producer gas or synthesis gas or syngas comprising carbon monoxide and hydrogen. More specifically, the process is effective for producing cooled syngas for downstream use. The process utilizes gasification of carbonaceous materials to produce a syngas followed by cooling of said syngas to produce cooled syngas and optionally cleaning said cooled syngas to produce a clean syngas for several downstream processes.BACKGROUND[0003]Gasification of carbonaceous materials to produce producer gas or synthesis gas or syngas comprising carbon monoxide and hydrogen is well known in the art. Typically, such a gasification process involves a partial oxidation or starved-air oxidation of carbonaceous material i...
