We take the basic principle of good faith in business, create interests for customers as the main purpose and establish long-term and friendly cooperation relationship with the majority of peers as the goal. We insist on using the rule of law to promote development, solve problems, make decisions and operate in accordance with the law. In order to know our solutions and organization.

Production Introduction

The pore size of 3A molecular sieve is 3A. It is mainly used to adsorb water and does not adsorb any molecules with a diameter greater than 3A. According to industrial application characteristics, molecular sieve has fast adsorption speed, regeneration times, crushing strength and anti-pollution ability, which improves the molecular sieve Utilizes efficiency and prolongs the service life of molecular sieves. It is a desiccant necessary for deep drying, refining and polymerization of gas and liquid phases in the petroleum and chemical industries.

Product feature and application

3A molecular sieve is mainly used for drying petroleum cracking gas, refinery gas, oilfield gas and olefin, etc. Such as ethylene, acetylene, propylene, butadiene drying, alcohol and various solvents dehydration. In order to prevent the adsorption of hydrocarbons above ethane, it is also used in the dehydration of rich natural gas.

Regeneration method:

(1) Removal of water: dry gas such as nitrogen, air, hydrogen, saturated hydrocarbon, etc. can be heated to 150-320°C and passed into the molecular sieve bed at a pressure of 0.3-0.5kg/m2 for about 3-4 hours, then Dry cold gas is introduced into the adsorber for about 2-3 hours, and the air is cooled to room temperature.

(2) Removal of organic substances: The adsorbent can be replaced from the molecular sieve with water vapor, and then heated to 150-320°C; regeneration can also be carried out by superheated steam or over-inert gas at 200-350°C. (Do not use gases that generate explosive mixtures in contact with adsorbates).

(3) The degassing substances can be regenerated by decompression method.
