Material berrien aplikazioa industria petrokimikoan

Mainly used for chemical raw material gas, pipeline blowing, atmosphere replacement, protective atmosphere, product transportation, etc. Mainly used in industries such as chemical, spandex, rubber, plastics, tires, polyurethane, biotechnology, intermediates, etc. Many chemical industries do not have high requirements for nitrogen purity, and many can be used with a purity greater than 98%. Acrylic oxidation explosion-proof, float glass process flow, protecting the chemical industry by creating an oxygen free atmosphere in chemical processes to improve production safety, fluid transportation power source, etc.

The chemical industry is the most widely used industry for nitrogen equipment, with polyvinyl chloride (PVC) being the most commonly used with a purity of 99.5% and a high flow rate. Polypropylene (PE), with a purity of 99.9% and a high flow rate, is divided into two parts for nitrogen application. The first part requires 99.9% nitrogen (small amount) for the loading and emptying of activators and catalysts. The reaction kettle uses 99.5% nitrogen (large amount), and it is customary to take a purity of 99.9%.

Polyethylene and aniline, with a purity of 99.95%, are used for catalyst regeneration of petrochemical product aniline with nitrogen gas, which is about four times higher than usual, but has a short service life.

Maleic anhydride and ethanol generally have a purity of 99.9%, while the petrochemical product polyoxymethylene (currently not many domestic manufacturers, with strong demand) has a purity of 99.9%.

Petroleum can be used for nitrogen purging of pipelines and containers in systems, nitrogen filling, replacement, leak detection of storage tanks, protection of flammable gases, as well as diesel hydrogenation and catalytic reforming. Its purity is generally 99.9%.

Phthalic anhydride, with a purity of 99%.

Polyester, upstream raw material PTA (refined p-phenylenedimethanol), with an actual purity of 95%, is generally taken as 99%.

In the PTA production process, high-purity nitrogen is used to blow bubbles, measure the liquid level of ethylene glycol raw materials in high and low temperature reaction vessels, measure the pressure difference between the high and low pressure ends, and transmit a 4-20mA standard signal, which is then converted into liquid level height. And use high-purity nitrogen to measure the pressure of the vacuum system, and use high-purity nitrogen to backwash the filter in PTA production process. Polyester chips are generally 99%~99.999% depending on the actual process. The downstream products of the chips are long and short fibers,99.9~99.999%.
