example 1

[0063] The following feed streams are supplied to the gasifier through a suitable mixing nozzle:

[0064] Chlorine-containing organic materials: 9037kg / hr

[0065] Oxygen (99.5% purity): 4419kg / hr

[0066] Recovered steam or moderator: 4540kg / hr

[0067] [58.8 wt% water vapor, 41.2 wt% hydrogen chloride]

[0068] Such a gasification reaction produces a hydrogen chloride-enriched synthesis gas stream and chamber conditions at a temperature of about 1450° C. and a pressure of 5 bar. In this example, the reactor is equipped with 6" (1524cm) thick hot-faced high-alumina refractory bricks, and the brick is covered with 9" (22.86cm) thick insulating refractory bricks. This refractory mounting design prevents heat loss to the vessel wall. The pressure vessel is a low alloy stainless steel cladding of 3mm thick nickel base alloy C-276. The container includes an integral jacket covering substantially all of the surface of the container. The jacket includes internal baffles to dir...

Abstract

A reactor for gasifying carbonaceous materials including an interior lining of one or more refractory materials, a pressure vessel enclosing the refractory lining, preferably a corrosion resistant cladding lining the pressure vessel and one or more channels for circulating a heat transfer fluid substantially jacketing the pressure vessel to control pressure vessel wall temperature and preferably also lining temperature during down time.

Description

technical field [0001] The invention relates to a refractory container for gasifying carbonaceous materials, in particular to a container wall structure and a temperature control system. Background technique [0002] Related inventions include a prior patent application entitled Method and Apparatus for the Production of One or More Useful Products from Less Valuable Halides, PCT International Application PCT / US / 98 / 26298, disclosing Dated July 1, 1999, International Publication No. WO99 / 32937. This PCT application discloses a method and apparatus by which, via a local oxidative reformulation step in a gasification reaction vessel, it is possible to achieve a process that will substantially contain halides, especially by-products obtained through a series of chemical manufacturing processes, as well as waste chlorine Convert hydrocarbons to one or more "higher value products". [0003] In this regard, gasification is a well-known technique for consuming by-products and usel...
