A separation method including: preparing a separation device including an absorption processor absorbing into an absorption liquid a target component in a fluid to be processed, by an absorption microduct and a cooling medium microduct positioned for heat exchange; causing the fluid to be processed and the absorption liquid to pass through the absorption microduct in mutual contact, thus causing the target component to be absorbed into the absorption liquid from the fluid to be processed; cooling the fluid to be processed and the absorption liquid by flowing a cooling medium through the cooling medium microduct, and causing heat exchange between the fluid to be processed and absorption liquid flowing through the absorption microduct and the cooling medium; and separating, into the fluid to be processed and the absorption liquid, the mixed fluid of the fluid to be processed after the target component has been absorbed by the absorption liquid.
摘要:
An compressor utilizing a flow of fluid down a vertical column to entrain air, or other gas, and compress it under the head of the flow. Compressed air is then separated from the flow in an air separation chamber at the bottom of the vertical column. In one application, the compressed gas is used to cool a deep underground mine. In another application, the system is used to separate chemical compounds from gaseous mixtures, such as the exhaust gases of fossil fuelled power plants. In a further application, the system is integrated into a domestic or commercial air conditioning system. The system can also be used as part of a minimum work vapour compression refrigerator.

The invention is directed to a treatment fluid comprising electrolyzed water and an amine, and methods for producing and using same in the treatment of a gas or liquid containing a contaminant such as an acid gas or a sulphur compound.
摘要:
A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

摘要:
A desiccant air conditioning system for cooling an air stream entering a building space includes a conditioner and a regenerator. The conditioner includes structures arranged in a substantially vertical orientation that are spaced apart from each other with an air stream gap between each pair of adjacent structures. Each structure has a surface facing an air stream gap across which a liquid desiccant can flow. The air stream flows through the air stream gaps between the structures such that the liquid desiccant dehumidifies the air stream. Each structure further includes a separate desiccant collector at a lower end of the surface for collecting liquid desiccant that has flowed across the surface of the structure. The desiccant collectors are spaced apart from each other to permit airflow therebetween. A photovoltaic-thermal module heats a heat transfer fluid used to heat the liquid desiccant in the regenerator.
摘要:
Various exemplary embodiments relate to a method and apparatus to reduce emissions of target emission gasses such as sulfur oxides, nitrogen oxides, and carbon oxides from combustion exhaust such as marine engine exhaust by gas membrane separation and liquid carrier chemical absorption. The membrane separation system consists of an absorption system containing semi-permeable hollow fiber membranes through which is circulated a liquid absorbent. Exhaust gases contact the exterior surface of the membranes and the target gasses selectively permeate the membrane wall and are absorbed by the liquid carrier(s) within the bore and thereby are removed from the exhaust stream.
