Process for producing a lean gas by the gasification of a fuel mainly in lump form |
May 16, 1978 |
| A process for producing lean gases in which solid fuels are gasified under superatmospheric pressure by a treatment with free oxygen-containing gases, water vapor, and other gasifying agents. In the process, fuel and gasifying agent are caused to flow in opposite directions, about 1.5 to |

Process for breaking emulsions in a tar-containing aqueous condensate |
December 27, 1977 |
| Gravity separation process for removing tar from water in a condensate formed by the cooling of a raw gas produced by the gasification or dry distillation of solid fuel such as coal. The tar and water condensate formed by cooling the raw gas to about 100.degree. C is enriched in a ta |

Process of desulfurizing hot gases |
June 15, 1976 |
| Gases produced by reacting fuels with oxygen containing gases and water vapor under pressure are desulfurized by scrubbing with a concentrated solution of one or more alkali salts of weak inorganic acids at a temperature near the atmospheric-pressure boiling point of the solution in |
| 3959972 |
Power plant process |
June 1, 1976 |
| Fossil fuels such as coal or oil are gasified by treatment under superatmospheric pressures with oxygen containing gasifying agents to produce a primary gas containing carbon monoxide and hydrogen. The primary gas is desulfurized and converted in increasing portion into methanol whic |
