    Abstract: PARTIAL OXIDATION PROCESS (D#73,184-1 FB) Sensible heat in the hot effluent gas stream leaving a partial oxidation gas generator for the production of gaseous mixtures comprising H2+CO i.e. synthesis gas, reducing gas, or fuel gas, is used at maximum temperature to heat a stream of gaseous heat transfer fluid comprising a portion of the product gas circulating in a substantially closed loop. The heat transfer fluid serves as the working fluid in a turbine that produces mechanical work, electrical energy, or both. Further, the heat transfer fluid leaving the turbine may be used to preheat hydrocarbonaceous feed and free-oxygen containing gas which is then introduced into the gas generator. A shell and tube heat exchanger in which cleaned and optionally purified generator gas is continuously bled from inside the tubes to the outside, or the reverse may be employed. By this means the surfaces of the tubes and headers in the heat exchanger may be protected from the surrounding hot effluent gas stream from the gas generator which enters the heat exchanger at maximum temperature. The bleedstream mixes with the effluent gas stream passing through the heat exchanger and a portion of this mixture is recycled as make-up. -I-

    Abstract: PARTIAL OXIDATION PROCESS (D#73,184-FB) Sensible heat in the hot effluent gas stream leaving a partial oxidation gas generator for the production of raw synthesis gas, reducing gas, or fuel gas is used at its maximum temperature to produce a continuous stream of superheated steam at a pressure which may exceed the pressure in the gas generator. The by-product superheated steam may be used as a dispersant or carrier of the fuel feed to the generator or as a temperature moderator. Optionally, a portion of the by-product superheated steam may be used as the working fluid in a turbine to produce mechanical work or electrical energy or both. The high steam superheat temperature results in a higher conversion efficiency. A shell and tube heat exchanger in which a stream of steam or cleaned generator gas is continuously bled from inside the tubes to the outside, or the reverse may be employed. The bleed stream mixes with the effluent gas stream passing through the heat exchanger. By this means the surfaces of the tubes and headers, if any, in the heat exchanger may be protected from the surrounding hot effluent gas stream from the gas generator, which enters the heat exchanger at maximum temperature. -I-

    Abstract: A process for the efficient production of power from non-gaseous carbonaceous fuels, such as coal, or heavy fuel oil, in a steam power plant in which the carbonaceous fuel is first gasified at relatively high pressure and temperature by partial oxidation with oxygen to produce a fuel gas, the fuel gas from the partial oxidation reaction is expanded to a lower pressure in a turbine. Undesirable compounds, e.g., sulfur compounds, are removed from the fuel gas, and the fuel gas supplied to a steam boiler for the production of power. The process of this invention provides an effective means for conversion of gas-fired steam generation facilities to coal or heavy fuel oil while at the same time increasing the power generating capacity of the installation, all with minimal atmospheric pollution. The process is effective for the conversion of other types of gas-fired heaters and boilers to coal or heavy fuel oil.
