摘要： A method to recover olefins and C2+ fractions from refineries gas streams. The traditional recovery methods employed at refineries are absorption with solvents and cryogenic technology using compression and expansion aided by external refrigeration systems. In contrast to known methods, there is provided first a pre-cooling heat exchanger on a feed line feeding the gas stream to a in-line mixer, secondly by injecting and mixing a stream of LNG to condense the C2+ fractions upstream of the fractionator. The temperature of the gas stream entering the fractionator is monitored downstream of the in-line mixer. A LNG stream is temperature controlled to flow through the injection inlet and mix with the feed gas at a temperature which results in the condensation of the C2+ fractions before entering the fractionator. A LNG reflux stream is temperature controlled to maintain fractionator overhead temperature. The fractionator bottoms temperature is controlled by a circulating reboiler stream.

摘要： A method to pre-treat an inlet natural gas stream at gas pressure reduction stations to produce LNG removes water and carbon dioxide from a natural gas stream. The energy required for the process is provided by recovering pressure energy in the inlet gas stream. The process eliminates the conventional gas pre-heating process at pressure reductions stations employing gas combustion heaters. The process provides a method to produce LNG at natural gas pressure reduction that meets product specifications.

摘要： A method to produce LNG at straddle plants. In contrast to known methods, there is provided a slipstream of a high pressure, pre-treated, pre-cooled natural gas stream to a straddle LNG plant section. The slipstream is further cooled, and processed in a high pressure column to a methane content of 85% or 85 plus by mole. The processed stream is further treated to remove carbon dioxide. The de-carbonated high pressure stream is further cooled in a heat exchanger by a counter-current vapor fraction of the expanded gas before entering an expander apparatus. The processed, treated and cooled gas is expanded into a separator. The produced LNG fraction is pumped to storage. A portion of the LNG fraction is used as a reflux stream to the high pressure column. The cold vapor fraction from the separator flows through counter-current heat exchangers, giving up its coolth energy before being re-compressed into the high pressure transmission gas pipeline.

摘要： A method for liquefying gas involving pre-treating the gas stream in a pre-treater to remove impurities, and then passing the gas stream through a first flow path of a first heat exchanger to lower a temperature of the gas stream. The gas stream is then passed through the gas expansion turbine to lower a pressure of the gas stream and further decrease the temperature of the gas stream. The gas stream is then passed into a primary separator to separate the gas stream into a liquid stream and a cold gas stream. The liquid stream is collected. Selected quantities of the cold gas stream are passed through a second flow path of the first heat exchanger whereby a heat exchange takes place to cool the gas stream flowing through the first flow path to maintain the temperature of the gas stream entering the gas expansion turbine at a temperature which promotes the production of liquids.

摘要： A method that combines a fuel cell with a Gas Recovery Unit (GRU) to a methanol plant to produce methanol at near zero GHG emissions. The fuel cell generates steam, carbon dioxide and electricity. A GRU unit condenses, separates, recovers, pressurizes and reheats the fuel cell anode exhaust stream. The GRU prepares a stream of natural gas and steam to feed the fuel cell anode and a stream of carbon dioxide and air to feed the fuel cell cathode. The GRU also prepares streams of carbon dioxide and steam as reactants for the stoichiometric mixture with natural gas to produce synthesis gas in an electric catalytic reformer at a methanol plant. The electric catalytic reformer uses electricity, steam and/or carbon dioxide reactants produced by the fuel cell to produce synthesis gas for conversion to methanol with low GHG emissions.

摘要： A method of upgrading oil using supercritical fluids generated by a fuel cell. The process uses supercritical carbon dioxide to control the specific gravity of the oil and supercritical water, the amount of which is controlled to achieve a desired oil/water ratio in processing oils to be upgraded. The process recovers the GHG emission stream from a fuel cell anode exhaust to produce supercritical fluids.

摘要： A method of stripping carbon dioxide from a stream of natural gas to be used in the production of liquid natural gas (LNG) comprises the steps of: passing a stream of natural gas through a stripping column; injecting a stripping agent into the stripping column, the stripping agent stripping carbon dioxide from the stream of natural gas and exiting the stripping column as a liquid phase; passing the stripping agent exiting the stripping column through a regenerator column to generate a carbon dioxide gas stream and a recovered stripping agent stream; and cooling the recovered stripping agent stream using a cryogenic vapour generated in the production of LNG and injecting the cooled, recovered stripping agent stream into the stripping column as the stripping agent.

摘要： A method for producing liquid natural gas (LNG) includes the following steps. Compressor stations forming part of existing natural-gas distribution network are identified. Compressor stations that are geographically suited for localized distribution of LNG are selected. Natural gas flowing through the selected compressor stations is diverted to provide a high pressure first natural gas stream and a high pressure second natural gas stream. A pressure of the first natural gas stream is lowered to produce cold temperatures through pressure let-down gas expansion and then the first natural gas stream is consumed as a fuel gas for an engine driving a compressor at the compressor station. The second natural gas stream is first cooled with the cold temperatures generated by the first natural gas stream, and then expanded to a lower pressure, thus producing LNG.
