    摘要： A system for enhanced oil recovery from an oil field that uses the associated gases collected to produce synthetic crude oil from a GTL plant. The pressure in the oil field is maintained by injecting nitrogen obtained from an ASU. The ASU is powered by an associated power plant that uses oxygen produced by the ASU and the Fisher Tropsch tail gases (hydrogen and steam) of the GTL plant. Nitrogen recovered from the tail gas of the power plant boosts the available nitrogen needed for the enhanced oil recovery operation.

    摘要： A method for increasing oil recovery from an oil reservoir by injection of gas into the reservoir, is described. The method comprises separation of air into an oxygen-rich fraction and a nitrogen-rich fraction, reformation of natural gas together with oxygen to produce a synthesis gas for production of methanol or other oxygenated hydrocarbons or higher hydrocarbons. The raw synthesis products and a waste gas from the synthesis are separated, and the nitrogen-rich fraction and at least a part of the waste gas are injected into the oil reservoir to increase the oil recovery from the reservoir. A plant for performing the method is also described.

    摘要： A method for recovering oil (24) from a natural oil reservoir (18) includes the steps of separating air to produce an oxygen rich stream (40) and a nitrogen rich stream (34), providing a natural gas stream (12) and feeding at least part of the oxygen rich stream (40) and the natural gas stream (12) into a gas to liquid or GTL conversion installation (42) to produce hydrocarbon products (44) and heat. The heat produced in the gas to liquid conversion installation is used to produce energy (20) to pressurize (16) the nitrogen in the nitrogen rich stream (34) to produce a pressurized nitrogen rich stream (22). The pressurized nitrogen rich stream (22) is passed into a natural oil reservoir (18) to enhance the recovery of oil (24) from the reservoir.

    摘要： A gas turbine is employed in a combined cycle system to produce one or more chemically useful products. Selected exhaust gases are fed back into the gas turbine compressor so as to establish a stable mixture of working fluid constituents for the gas turbine. The gas turbine is preferably configured in a combined cycle arrangement and both mechanical and thermal energy is extracted from the flow of gases through the load turbine, this energy being used in the production of useful process fluids. The methods and apparatus of the present invention are particularly unique in that here the principal output of the combined cycle plant is not electrical energy but rather valuable chemical products. In short, the gas turbine is being employed as a high-temperature reactor from which both mechanical and thermal energy may be extracted as a result of the energy in the gaseous reaction products.
