Angstrom Advanced Nitrogen Purifying System

Introduction
The purity of nitrogen generated by nitrogen generator can range from 95% to 99.99%. If higher purity is required, a non-hydrogen or hydrogen-using purifying system can be equipped.This system is installed after the Nitrogen Generator and further removes oxygen and other by-products. As a result, a final purity of 99.9995% or above is achieved. Angstrom Advanced Inc supplies the non-hydrogen deoxidizing purifying system and hydrogen deoxidizing purifying system.

Angstrom Advanced Nitrogen Generating Plant by Membrane Separation


 Introduction
The compressed air compressor filter into the polymer membrane filters, a variety of gas in the film in the solubility and proliferation of different factors, leading to different gases in the membrane penetration rate in a relatively different. According to the characteristics, various gases can be divided into "rapid gas" and "slow gas". After being compacted and purified (to remove oil, water and dust) the air will enter the membrane separation to separate. First, the O2, CO2 and some vapor will infiltrate into the membrane wall and then exit through the discharge port by air pressure; since the infiltrating speed of N2 is slower, it will flow out from the gas collector at the end of the pressure box and finally enter nitrogen buffer tank.

Electrolysis Process Overview
Electrolysis is the passage of a direct electric current through an ionic substance that is either molten or dissolved in a suitable solvent, resulting in chemical reactions at the electrodes and separation of materials. 
The main components required to achieve electrolysis are :
- An electrolyte : a substance containing free ions which are the carriers of electric current in the electrolyte.
- If the ions are not mobile, as in a solid salt then electrolysis cannot occur.
- A direct current (DC) supply: provides the energy necessary to create or discharge the ions in the electrolyte.
- Electric current is carried by electrons in the external circuit.
- Two electrodes: an electrical conductor which provides the physical interface between the electrical circuit providing the energy and the electrolyte. Electrodes of metal, graphite and semiconductor material are widely used. Choice of suitable electrode depends on chemical
reactivity between the electrode and electrolyte and the cost of manufacture.
