This oxygen and nitrogen generation system uses pressure swing adsorption principles at normal temperatures, along with clean, compressed air as the raw material, and a carbon molecular sieve as the adsorbent. Due to different adsorption of oxygen and nitrogen onto the carbon molecular sieve surface as well as different diffusion rates through the open or closed program control valve, separation of the two gasses is achieved, and nitrogen of required purity is produced.
The system vaporizes liquid ammonia, and heats it with a catalyst until decomposition occurs, creating a mixture of gas consisting of 75% hydrogen and 25% nitrogen. Based on the principle that the molecular sieve adsorbs ammonia and water at different temperatures, high purity gas is produced by heat regenerating through the mixture working at normal temperature.Hydrogen production 5-500nm3/h Impurity oxygen 2ppm Residual ammonia 3ppm Dew point -65°c Working pressure 0.05-0.2mpa
Methanol is converted to co and h2 with the action of the catalyst; -co and h2o are converted to co2 and h2 with the action of the catalyst; -co2 and trace co are separated from the decomposed gases by psa technology, and high purity of h2 is generated.
This separation process occurs in an adsorption tower and is advantageous in its low cost, low capacity, minimal maintenance requirements and user-friendly interface. The h2 purifying system removes oxygen from hydrogen via a catalyst to obtain high purity h2 after adsorption and drying through the dust filter. The system can remove oxygen down to levels of 1ppm. Through one step of purification, the purity of the hydrogen generated can reach between 99.999~99.9999% and the dew point can be lower than -70°c; through a second purification step, impurities can be , 0.8mpa H2 purity % >98-99.999% Dew point , -60°c Oxygen content , 1ppm
Introduction: Hydrogen electrolyte and oxygen electrolyte circulate separately, hydrogen electrolyte pumps into hydrogen fuel cell directly and oxygen electrolyte pumps into oxygen cell directly, and therefore gets higher purity of hydrogen and oxygen gas. Specifications: O2 purity % >99.5 Power consumption (dc) < 4.5 kw.H/m3h2 Electrolyte 30% koh Work pressure 0.5-5.0mpa
We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.
