Still another process, called BI-GAS, was developed by Bituminous Coal Research in a 73 t/d pilot plant in Homer City, Peimsylvania. In this entrained-bed process, pulverized coal slurry was dried and blown into the second stage of the gasifier to contact 1205°C gases at ca 6.9 MPa (1000 psi) for a few seconds residence time. Unreacted char is separated and recycled to the first stage to react with oxygen and steam at ca 1650°C to produce hot gas and molten slag that is tapped. 

Bi-Gas [Bituminous Gas] A coal gasification process using a two-stage, entrained-flow slagging gasifier. Developed by Bituminous Coal Research. A 120-tons-per-day pilot plant was built in 1976 at Homer City, PA, under sponsorship from the U.S. Energy Research and Development Administration and the American Gas Association. 

The submerged-flame technique developed by BASF represents the latest de> cIopment in autothermal processes. Within a liquid hydrocarbon, a flame creates a suf ciently high temperature in its vicinity to cause the formation of light products, tnduding acetylene. The gases are quendied in the cold zones of the liquid, and the carbon black formed is sent with the hydrocarbon to the burner. The reactor can operate undo pressure with any hydrocarbon oomponnd, without the substandal producdon of carbon black. The weak point of the device is the control of the burner, which is difficult to achieve due to the bi gas flow velocity (Fig. 5.13). 

Some of these processes which are in the stage of pilot plants or design of demonstration plants are the HYGAS, BI-GAS, GO2 Acceptor, Synthane, and Self-Agglomerating Ash gasification processes (5). These processes are designed to fill the pipeline distribution systems and to mix... 

Bis-GA is an epoxy diaciylate. It caused contact dermatitis in a process worker it was contained in UV-light-curable acrylic paints. 

The other processes under development, the main ones being Hygas, C02 Acceptor, Synthane, Bi-Gas, COED, COGAS, Atgas-Patgas, Molten Salt, B W, and Exxon Catalytic, are designed with three main objectives in mind ...
