Adsorption technologies of air separation allow to generate oxygen in quantities of several hundred tons per day. The basis of adsorption technology is the variable absorptive capacity of the adsorbent depending on temperature and pressure. The driving force is given by the difference between the actual and the equilibrium concentration of substance adsorbed on surface of the adsorbent. There are two main technologies of adsorption air separation: Pressure Swing Adsorption (PSA) and Temperature Swing Adsorption (TSA). In order to carry out air separation by PSA methods, it is required to provide electricity to the compressor or vacuum pump. In case of the TSA method, it is necessary to provide heat to the adsorption bed during regeneration stage. There are also combinations of these processes. In the case of mixed methods, the adsorption process takes place under elevated pressure, whereas the regeneration - under vacuum or at elevated temperature. The article presents an economic a...

Thanks to all the students of the Center for Space Exploration and Technology Research (cSETR) at UTEP for their help throughout my graduate career. Also, I extend my thanks to Angle Lerma, David Powell, and Alberto Delgado from the Machine Shop at UTEP as well as Victor Amezquita from Amezco Precision for their support and aid in manufacturing the parts for the assembly. My utmost gratitude I offer to my companion in this path. Her ever-present love and support has given me the inspiration to carry out profession as an engineer, and to carry out my life.

A twisted aerosol singlet oxygen generator (TA-SOG), which is a new high-pressure SOG for the supersonic chemical oxygen-iodine laser (COIL), was developed. Its operational characteristics were compared to those of a conventional liquid-jet-type singlet oxygen generator. It was shown that TA-SOG is operated at an internal gas velocity of 85 m/s, which is three times higher than that of the jet-type SOG. Cl2 utilization of 70% and singlet oxygen O2(1 1) yield of 85% were obtained under this condition. The results of our two-dimensional model calculation suggested that there must be some enhancement of a specific surface area in the reaction zone. The mechanism of this effect is discussed.

Producing large volumes of life saving oxygen at high purity and low cost is of utmost importance . Some Methods of oxygen generation are Pressure Swing Adsorption, Cryogenic Air Separation, Ion Transport Membrane. PSA devices are suited for producing small volume of oxygen, on the order of 10 tonnes per day. Cryogenic Air Separation Unit is used for producing for large volume of oxygen but this method involves high cost. As compared with Cryogenic Air Separation method Ion Transport Membrane is more efficient and produces large volume of oxygen at low cost with highest purity oxygen (>99.5%)

This paper reports the design, fabrication, and proof of concept demonstration of a singlet oxygen generator (SOG) that operates on the microscale. The micro-SOG (µSOG) chip is implemented in a three-wafer stack using deep reactive ion etching (DRIE) and wafer bonding as key technologies. The device creates singlet delta oxygen (O 2 (a)) in an array of packed-bed reaction channels fed by inlet manifolds with pressure drop channels that ballast the flow. An integrated capillary array separates the liquid and gas by-products, and a microscale heat exchanger removes excess heat of reaction. The fabrication process and package are designed to minimize collisional losses and wall deactivation of O 2 (a). The design, fabrication, and package of the device are documented. Proof of concept demonstration of the device is given by optical emission measurements of the spontaneous decay of the O 2 (a) molecule into its triplet state and by the observation of the emission from dimol pairs of O 2 (a) molecules.

As we know that nowadays, air pollution is increasing because of gases present in the atmosphere. Gases such as Carbon Dioxide, Methane, Carbon Monoxide are increasing rapidly. So, Air Quality Index is not upto the health mark. So, it is definite that we would be having more breathing problem in the future. There would be the time when we won't be able to get any oxygen on this planet. So, Our main motive is to reduces such harmful gases and purify the oxygen artificially.
