    摘要： Olefins may be recovered from a methanol to olefins reactor effluent by initially feeding the effluent to an absorber demethanizer to contact the effluent with an absorbent to recover an overheads including methane and ethylene and a bottoms including the absorbent, ethylene, and ethane. The bottoms are separated to recover an ethylene fraction and an ethane fraction. The overheads are cooled and partially condensed in a first heat exchanger to a temperature of −40° C. or greater. The resulting stream, or a portion thereof, may be further cooled and condensed via indirect heat exchange with a mixed refrigerant to a temperature of less than −40° C. The non-condensed vapors are separated from the condensed liquids to form a liquid fraction and a methane fraction. The liquid fraction is fed to the absorber demethanizer as reflux, and the methane and ethane fractions combined to form the mixed refrigerant.

    摘要： Liquid nitrogen is filled in a low temperature vessel; an ejector that sucks liquid nitrogen by blowing a cooling agent (liquid or gas) such as low temperature helium gas or liquid helium of pressure higher than in the space within the vessel is disposed in the vessel; the liquid nitrogen blown with the cooling agent is cooled by the cooling agent to become fine particles of solid nitrogen which fall down; and gas in a space of the vessel is discharged out of the vessel so as to maintain the pressure of the space higher than the atmospheric pressure.A gaseous phase of liquid nitrogen in an adiabatic vessel is depressurized to vaporize nitrogen in a liquid phase so that a temperature of the nitrogen is reached to the triple point of nitrogen by lowering temperature thereby and solid nitrogen is produced by keeping at the triple point, and that the produced solid nitrogen is transformed into slush by stirring the content of the adiabatic vessel.In a method for cooling a super conductive body in which a material showing a state of super conductance in the vicinity of the temperature of liquid nitrogen or of the temperature liquid nitrogen and solid nitrogen coexist is used, a method for cooling a super conductive body characterized in that the super conductive body is immersed in slush nitrogen held in an adiabatic vessel, and that the body is contacted with slush nitrogen to cool.

    摘要： A wet hydrocarbon stream comprising at least methane and water is dried thereby forming an effluent stream and a wet disposal stream. Before drying the wet hydrocarbon stream is cooled by indirectly heat exchanging against the effluent stream followed by indirectly heat exchanging against an auxiliary refrigerant stream. The effluent stream is subsequently passed to a further heat exchanger where the effluent stream is cooled against an evaporating refrigerant stream which is subsequently discharged from the further heat exchanger as a spent refrigerant stream. A refrigerant stream in compressed condition is formed by compressing the spent refrigerant and the auxiliary refrigerant stream that is discharged from the indirectly heat exchanging with the wet hydrocarbon stream, whereby allowing direct heat exchanging between the discharged auxiliary refrigerant stream and the spent refrigerant stream before said compressing.
