Oxygen and nitrogen supply mode at the hottest sit

  • Detail

On site oxygen and nitrogen supply mode

I. on site gas production

1. Low temperature gas production (oxygen and nitrogen)

low temperature gas production technology, namely deep freezing air separation technology, is a relatively traditional air separation method with a history of more than 100 years. Its basic principle is to freeze the air to liquefy it, and use the different boiling points of each component in the air to separate each component through distillation

2. Non low temperature gas production (membrane separation, pressure swing adsorption system)

pressure swing adsorption (PSA) is a high-tech used to separate gas mixtures in adsorption and separation technology. PSA gas separation technology was born in the 1960s when the world was in an energy crisis. The initial PSA technology was applied to the production of oxygen from the air and gas drying. With the development of technology, it has been widely used in the production of nitrogen, hydrogen, carbon dioxide and other industrial gases. PSA Technology, especially PSA nitrogen and PSA oxygen production technology, has been developed by leaps and bounds in the past 10 years, including new processes New technologies continue to emerge

membrane separation technology is a new separation technology developed in recent decades, which is mainly used to produce nitrogen and oxygen in the air separation industry

II. Tank car is the first industrialized base based on graphene material and utilization in China to transport liquid bulk gas

and coated with high-purity graphite and salt free butter. It is a way to fill liquid bulk gas from cryogenic air separation station with tank car, transport it to gas consumption site, transfer it to on-site low-temperature storage tank, and then supply gas to all gas consumption points

III. transporting gaseous bulk gas with torpedo tank car

is a gas supply method similar to transporting liquid bulk gas with tank car, but the transported medium changes from liquid to gas

IV. pipeline gas supply

centralized gas transmission from the gas generation station to each gas consumption site through the pipeline

v. industrial steel cylinders

from the gas generation station to the high-pressure steel cylinders, Japan Steel in East China reduced the coke purchase price by 30 yuan/ton, and the high-pressure gas was transported to each gas consumption site (end)
