Separation and purification technology of pressure swing adsorption nitrogen production

The principle of pressure swing adsorption nitrogen production technology:
The zui simple application unit of pressure swing adsorption nitrogen production technology consists of two adsorption towers, inlet and outlet pipelines, PLC, program-controlled valves, analysis and field instruments filled with carbon molecular sieves. When compressed air enters from the inlet end and flows through the adsorbent (carbon molecular sieve) in the adsorption tower, oxygen molecules in the compressed air are adsorbed, while unabsorbed nitrogen molecules are enriched and flow out from the outlet end; When the carbon molecular sieve is saturated, the intake valve and the outlet valve are closed, and the exhaust valve is opened to desorb the adsorbent, and the regeneration gas is completely regenerated and used for the next adsorption cycle. Sichuan Yimai Technology PSA-N 2 process adopts the advanced process and supporting technology of “unequal potential equalization”, which greatly improves the yield and yield of pressure swing adsorption nitrogen production. Received national patents.

The technical characteristics of the first pulse technology pressure swing adsorption nitrogen production equipment:
1) Have independent patent technology, adopt advanced patent adsorber and unequal equalization process;
2) Modular design for quick installation and commissioning;
3) Energy consumption is 8%-15% lower than conventional pressure swing adsorption nitrogen production equipment;
4) Unique air intake mode, using advanced gas distribution and adsorption tower structure;
5) Adopting “storm-type” molecular sieve filling technology matched with foreign molecular sieves;
6) Fully automatic unmanned operation, automatic emission of unqualified gas;
7) The adsorption tower technology matched with the imported molecular sieve can realize the normal service life of the molecular sieve for 10 years.

Most of the Fluorine-Containing Phenylamine products are a light yellow oily liquid, relatively high density, insoluble in water. Most of them are used in the manufacturing of pesticides and dye intermediates, small part of them can be used as an analytical reagent. The steam or smoke of fluorine-Containing Phenylamine series is irritated to eyes, mucous membranes and upper respiratory. Vapor and air can form explosive mixtures, in case of fire, high-heat combustion caused the explosion. And oxidant may react. Decomposition by high fever and emit toxic gases. In case of high fever, increased pressure within containers, cracking and the risk of explosion. Protective measures must be done carefully during product storage. Once the fire occurred, it must be immediately evacuated from air leakage,personnel to a safe area, prohibit access to the contaminated area. Recommended emergency personnel wearing self-contained breathing apparatus and wear chemical protective clothing. In the ambulance personnel to ensure proper safety measures, immediately use foam, carbon dioxide, dry, sandy soil to put out a fire.
