Abstract: A process for treating a flue gas produced in at least one upstream unit operating at a nominal operating pressure, the flue gas containing from 5 mol % to 90 mol % of CO2 on a wet basis and being at a pressure between 0.5 and 2 bar absolute. The process includes treating, via at least one downstream treatment unit, all or virtually all of the stream of flue gas originating from the upstream unit or upstream units, thereby producing, from the flue gas, a gaseous or liquid stream rich in CO2 which contains more than 50 mol % of CO2. Then enabling the stream of flue gas to communicate, between the upstream unit and the downstream unit with a stack opening to the atmosphere, and this outlet line is left open or partially open in nominal operation thereby equilibrating the pressure in the stream of flue gas to atmospheric pressure.

Abstract: A method for selection an adsorbent selection, a pressure swing adsorption method, and a system therefor are provided. The selection method includes obtaining the slope at an initial pressure of an adsorption isotherm with respect to a target adsorbate of each adsorbent among a plurality of adsorbents, in which each adsorption isotherm is a curve representing adsorption capacity varying with pressure at a specific temperature; obtaining the adsorption capacity of each adsorbent on the target adsorbate under the specific temperature and a specific pressure; and selecting a target adsorbent for adsorbing the target adsorbate from the plurality of adsorbents according to the slope and the adsorption capacity of each adsorbent. In a pressure swing adsorption process, a pressure swing adsorption cycle can be optimized, the amount of an adsorbent used can be reduced, and operation and production costs of pressure swing adsorption can consequently be reduced.

Abstract: The present invention relates to a computer-implemented method for monitoring at least one exhaust gas purification system for purifying an exhaust gas stream to be purified of an industrial system or an industrial process. The method comprises retrieving system data of the exhaust gas purification system from a data cloud. The system data stored in the data cloud were at least partially received beforehand by the data cloud from the exhaust gas purification system. The system data relate to at least measurement data of at least one sensor of the exhaust gas purification system and/or data about at least one adjustable parameter of the exhaust gas purification system. The method further comprises determining at least one quantity characterizing the exhaust gas purification system based on the retrieved system data.

Abstract: Methods and systems for measuring the concentration of a light gas in a main flow stream are disclosed herein. The methods include calculating a control parameter as a function of the concentration of the light gas in the main flow stream; dividing a portion of the main flow stream to produce a feed stream; and separating the feed stream by selective permeation across a semi-permeable membrane to produce a permeate stream enriched in the light gas and a retentate depleted in the light gas. A ratio of the flow rate of the feed stream to the flow rate of the main flow stream may be increased or decreased according to the control parameter. In addition, an area of the semi-permeable membrane may be increased or decreased according to the control parameter.

Abstract: An ionization device may be configured to be portable, and to rest on a surface such as a floor or desk top. The ionization device includes an air-intake port, an ion generator, an ozone catalyst for removing at least some ozone from air, and an air discharge. Air enters the device through the air-intake port, and at least some of the air is ionized to remove particulates. The air is then moved past or through the ozone catalyst to remove at least some of the ozone from the air. A controller may be used to monitor particulates, temperature, humidity, and/or other relevant factors and/or to adjust the ionization level.
