Safe and economical, the MOS Oxygen Plant from MOS TECHNO ENGINEERS is a medium pressure plant, with an efficient expansion engine, that lowers operating pressures to a remarkable 32-35 Kg/cm2g, reduces power consumption and adds to safety.
A molecular sieve battery assembly for adsorption of ;moisture and carbon Dioxide is another money-saving device in the MOS plant.
Capable of simultaneously producing Oxygen and Nitrogen, the MOS plant has an internal compression liquid oxygen pump to fill dry gaseous Oxygen and Nitrogen in cylinders.
It is also capable of producing bone-dry Nitrogen up to 1ppm ( in modified version plant ).
The installation and commissioning of the plant can be also arranged under our supervision..
Description of MOS Oxygen Plant
The free atmospheric air is sucked by a multistage air compressor through a filter and compressed to the working pressure. After each stage, intermediate cooler and water separators are provided. The compressed air and then passes through the evaporation pre-cooler and then to the molecular sieve battery where the moisture and carbon dioxide are removed from the process air. It then passes through the heat exchanger No. 1 where it is cooled by the out-going waste Nitrogen and product Oxygen.
A part of this cold air then flows through and Expansion machine and the balance through the 2nd heat exchanger. The ratio of the two air streams is controlled by an expansion valve, R1.
Both these streams of air then unite in the lower pressure column where it partially liquefies.
The liquid air (rich liquid) then passes through the expansion valve R2 to Upper column which is at a lower pressure than the lower column. Similarly the liquid nitrogen (poor liquid) travels from the lower column to the upper column through and expansion valve R3 where the separation of Oxygen and Nitrogen occurs. Nitrogen being more volatile, passes out as a gas from the top of the column and this waste Nitrogen flows through both the heat exchangers cooling the incoming air.
Similarly the product oxygen is also passed through the two heat exchangers to cool the incoming air and then to the filling manifold via a liquid pump. If a small amount of air is Vented out from the upper column, higher purity Nitrogen can also be obtained from this plant. R4 valve is all is provided in order to fasten cooling during start-up.
