Nitrogen drying device

Chlorine drying technology:

Technical introduction

Traditional chlorine gas drying adopts concentrated sulfuric acid dehydration process, but the water content can only reach about 50ppm, and waste acid is produced during the process; Moreover, the dehydration depth of the product cannot meet the requirements of some special industries. Therefore, the special process and special adsorbent developed by our company can reduce the water content of chlorine gas to below 10ppm by temperature swing adsorption dehydration and drying, which exceeds the level of other advanced countries in the world.

Unit scale: 100~5000Nm3/h

Technical features:

The process flow is simple, the dehydration precision is high, and there is no waste liquid and waste gas generated;

High degree of automation, simple operation, convenient and fast driving;

Low investment, low operation cost and remarkable economic efficiency.

Application field:

Fine chemical industry, trichlorosilane, polycrystalline silicon and other industries.

Hydrogen chloride drying technology

Technical introduction:

The traditional hydrogen chloride dehydration and drying adopts concentrated sulfuric acid dehydration or freezing dehydration process, which has low dehydration accuracy, produces waste acid in the sulfuric acid drying process, and requires high equipment materials; For this reason, the special process and special adsorbent developed by our company for temperature swing adsorption dehydration drying can reduce the water content of hydrogen chloride to below 20ppm, surpassing the level of other advanced countries in the world.

Unit scale: 100~5000Nm3/h

Technical features:

The process flow is simple, with high purity and little corrosion;

High degree of automation, simple operation, convenient and fast driving;

Low investment, low operation cost and remarkable economic efficiency.

Application field:

Chlor alkali chemical industry, fine chemical industry, pharmaceutical chemical industry, trichlorosilane, polycrystalline silicon and other industries.

Acetylene drying technology

Technical introduction:

Due to the special nature of acetylene gas, the traditional acetylene drying method adopts the freezing method, which has high operation cost and low dehydration accuracy, affects the subsequent product quality and high selection of equipment materials, and its investment is too high; For this reason, the special process and special adsorbent developed by our company for PSA dehydration and drying can make the water content in acetylene gas lower than 20ppm, and the device operates safely and reliably, reaching the domestic advanced level.

Unit scale: 100~5000Nm3/h

Technical features:

The process flow is simple and the dewatering precision is high;

High degree of automation, simple operation, convenient and fast driving;

Low investment and operation cost

Environmental protection, safety and stability.

Application field:

Chlor alkali chemical industry, fine chemical industry, pharmaceutical chemical industry, etc.

Hydrogen chloride purification technology

Technical introduction:

Some industrial units will produce hydrogen chloride tail gas. Most of the previous treatment methods used water adsorption to produce hydrochloric acid, which is difficult to sell due to limited transportation and use; For this reason, the special process and special adsorbent developed by our company are used for temperature (pressure) adsorption purification process, which can get high-purity chlorine chloride return system for reuse and improve the added value of products.

Unit scale: 50~5000Nm3/h

HCl purity: 98~99.999%

Technical features:

The process flow is simple, with high purity and little corrosion;

High degree of automation, simple operation, convenient and fast driving;

Low investment, low operation cost and remarkable economic efficiency.

Application field:

Chlor alkali chemical industry, fine chemical industry, pharmaceutical chemical industry, trichlorosilane, polycrystalline silicon and other industries.
