摘要： The present provides a helium gas separation and recovery process involving cryogenic fractionation process, which comprises cooling a dehydrated high-pressure gas stream while maintain velocity and pressure of the stream; reducing pressure of the dehydrated high-pressure gas stream via a Joule-Thompson's process to obtain a partially liquefied gas stream; and iii) subjecting the partially liquefied gas stream to at least one gas-liquid separation process to obtain at least one liquid stream and a gaseous stream comprising helium, and a residual amount of the gaseous components; recycling the liquid stream obtained in step iii) for use as cooling refrigerant to cool the dehydrated high-pressure gas stream; and purifying the unrefined helium gas stream using pressure swing adsorption (PSA) and/or membrane separation process to obtain a helium product stream having a purity of 98.0 mole % or more.

摘要： A method for treating arsenic-containing flue gas is disclosed. In the method, the arsenic-containing flue gas is subjected to a dry pre-dedusting treatment, and the dedusted flue gas is pre-cooled and then introduced into a vortex quenching system. The arsenic-containing flue gas is divided into high-temperature flue gas and low-temperature flue gas through the vortex quenching system. The outlet temperature of the low-temperature flue gas is dropped below the desublimation temperature of gaseous arsenic trioxide. The low-temperature flue gas is subjected to a gas-solid separation to obtain solid arsenic trioxide and treated flue gas.

摘要： Provided is a cyclonic fluid separator, method of fluid separation, and a method of installing a cyclonic fluid separator. The cyclonic fluid separator includes a throat portion arranged between a converging fluid inlet section and a diverging fluid outlet section including an inner primary outlet for condensables depleted fluid components and an outer secondary outlet for condensables enriched fluid components. A central body extends along a central axis of the cyclonic fluid separator through at least part of the inlet section of the separator. The central body has, at a location upstream of the throat portion, a larger outer width than a smallest inner width of the throat portion; swirl imparting means arranged in the inlet section for creating a swirling motion of the fluid within at least part of the separator. The swirl imparting means are adjustable; and an adjusting mechanism configured for adjusting the swirl imparting means for varying the swirling motion of the fluid.

摘要： A system and method separate a process fluid stream into a liquid-phase carbon dioxide stream and a carbon dioxide-depleted stream containing the remaining light gases. The system and method use a drying heat exchanger to contact the process fluid stream with a dryer contact liquid to remove moisture from a process fluid stream. The gaseous process fluid stream is separated from the wet dryer contact liquid stream and is directed to an extraction heat exchanger where it is contacted with an extraction contact liquid so that carbon dioxide is removed from the process fluid stream with a treated process fluid stream and a carbon dioxide enriched extraction contact liquid stream being formed.

摘要： A method is disclosed. The method includes directing a stream into a compressor station, the stream being a pre-cooled effluent gaseous stream including N2, O2, CO2, water vapor, and hazardous emissions when it is directed into the compressor station, bringing the stream to a medium range pressure by performing an isothermal compression using the compressor station, sending the stream into a first regenerative heat exchanger, at which a temperature of the stream is lowered to below a condensation temperature of CO2 by the purified cold stream after its expansion in the downstream expander and causing partial stream liquefaction thereby transitioning or transforming the incoming stream into a two-phase stream, directing the two-phase flow into one or more inertia separators to collect said liquid phase including liquefied emissions and CO2 in a pressurized storage, and directing a thusly purified gaseous portion of a two-phase stream that leaves the one or more inertia separators into an expander.

摘要： Embodiments presented provide a compressed air and liquid separator having a shell adapted to be vertically or horizontally oriented in use. The shell has an inlet end and an outlet end and defines a separating chamber therein. An inlet plate is coupled to the inlet end of the shell and provides a compressed gas ingress into the separating chamber, the compressed gas including a liquid therein. A plurality of inlet nozzles is disposed in the inlet plate, each inlet nozzle having an inner diameter and a length that are selected so as to accelerate the compressed gas therethrough to below a dew point thereof. A plurality of separating baffles positioned within the separating chamber above the compressed gas ingress, the separating baffles providing a means for separating the liquid from the compressed gas. An outlet plate is coupled to the outlet end of the shell, the outlet plate providing a compressed gas egress out of the separating chamber.
