摘要:
The present invention relates to a process for removing carbon dioxide from a mixture of gases, and to a process for reducing the partial pressure of carbon dioxide in an enclosed space. The processes of the present invention employ a carbon dioxide adsorbent comprising benzyl amine moieties immobilised on a solid support. The process comprises regenerating the adsorbent by heating to a temperature in the range from 40°C to 75°C.

A cartridge (20) mounting an air treatment material in a housing (26) defining a housing in a perimeter. The air treatment material is received within the housing (26), and spaced from the inner wall of the housing by a plurality of resilient sheets. There is an inlet direction into the housing (26) for air flowing across the air treatment material and an outlet opening on an opposed side of the housing. There are top (32) and bottom (28) surfaces and side surfaces forming a perimeter about the air treatment material. The resilient sheets extend substantially continuously across the side surfaces and the top (32) and bottom (28) surfaces at least at the inlet end to increase airflow across the air treatment material. An enclosed inhabited space is also disclosed and claimed.

An air inert gas generating system consists of heat exchangers, a heating element, and a plurality of solid oxide electrochemical gas separator (SOEGS) cells (2). The SOEGS cells (2) are interconnected in series to create a stack (14A). A voltage is applied to the stack causing oxygen ions to be transported from the air flowing through the cathode through the electrolyte (8) to the anode side of the SOEGS, resulting in oxygen-depleted gas. The oxygen-depleted gas can be used to inert the ullage of aircraft fuel tank or support the fire suppression system in the cargo hold. The oxygen-enriched gas can be used for other purposes.

A nitrogen generation system includes a heat exchanger (12, 112, 212) for receiving supply air and cooling air and providing temperature conditioned supply air, a flow control valve (16, 116, 216) for controlling a flow of the cooling air through the heat exchanger, and an air separation module (26, 126, 226) for receiving the temperature conditioned supply air and generating nitrogen-enriched air. The nitrogen generation system also includes a sensor (34, 134, 234) for measuring a parameter of the nitrogen-enriched air selected from the group consisting of a temperature, a flow rate, an oxygen concentration, and combinations thereof, and a controller connected to the sensor and the flow control valve for controlling the flow of the cooling air through the heat exchanger based on the parameter of the nitrogen-enriched air measured by the sensor.
