Best Selling High Recovery 97%Purity Voc Filtration Membranes Plant for Gasoline Treatment And Recovery
Technical Principle
The organic steam separation membrane is a rubbery state polymer membrane, and its separation process is controlled by selective dissolution. Organic vapors with high molecular weight and boiling points, such as ethylene, propylene, chloromethane, light hydrocarbon components, etc., have a high solubility inside the membrane, allowing for fast permeation. This enables the separation from gases with smaller molecular weight and lower boiling points.

Applications In Industries
1.Polypropylene Industry
1) Working principle overview
In intermittent small-scale polypropylene production, the use of compression/condensation methods can reduce propylene consumption from 1.12-1.15 to 1.07-1.09 for each ton of polypropylene produced. Nevertheless, for every ton of polypropylene produced, a significant amount of propylene monomer, ranging from 70 to 90 kg, is still lost.
In a 200,000-ton BP-Amoco gas-phase propylene polymerization process, over 2,700 tons of propylene are lost annually during the polymerization reaction and resin degassing processes.

3）Key features
* Propylene Monomer Recovery Rate Exceeding 95%;
* Significant Reduction in Consumption for Small-Scale Production Processes;
* Significant Reduction in Consumption for Small-Scale Production Processes;
* Recycling of Purified Nitrogen to 97-99% Purity.
2.Polyethylene Industry
1) In the BP Innovene polyethylene production process:
In the polyethylene production process, the release gas of polymerization reaction and resin degassing process contains a lot of ethylene monomer and other hydrocarbons, which will cause a lot of economic losses.
During the synthesis of High-Density Polyethylene (HDPE) and Linear Low-Density Polyethylene (LLDPE), the single-pass conversion rate of ethylene monomers is less than 100%. Unreacted ethylene monomers and other hydrocarbons are directed through a recycling compressor and reintroduced into the reactor for further reaction. In this recycling process, to prevent the accumulation of inert gases such as nitrogen, a portion of the recycled gas is released as relief gas. Unfortunately, this relief gas contains approximately 40% ethylene and 20% other hydrocarbons, leading to significant economic losses.

3.Polyvinyl Chloride (PVC) Industry
1) In the production process
In the chloroethylene production process using the calcium carbide method, during the chloroethylene distillation and purification process, a distillation tail gas is separated.
Due to limitations in the operating pressure and temperature of the tail cooler, the tail gas typically contains 6-30% chloroethylene monomers. This not only pollutes the surrounding atmospheric environment but also leads to an increase in the consumption quota of calcium carbide and wastage of raw materials. As a result, it raises the production costs in the polyvinyl chloride (PVC) industry.

3）Key features
1. High Recovery Rates:
Achieves a recovery of 95% for chloroethylene and 85% for acetylene from the distillation tail gas.
2. Significant Reduction in Treatment Load:
Substantially decreases the processing load on adsorption or absorption devices.
3. Reduced Consumption Quota:
Lowers the consumption of calcium carbide per ton of PVC by 30 kg.
4. Elimination or Temperature Reduction of Tail Gas Condenser:
Allows for the elimination of the tail gas condenser or a reduction in its operating temperature.
