Характеристики
Membrane-Assisted Organic Steam Recovery Membrane Steam Organic Recovery Membrane-Based Organic Steam Reclamation
All Wholesale High Performance 99%Purity Organic Steam Recovery Membrane System for Ethylene Recovery
Technical Principle
Membrane Organic Steam Recovery Equipment
Organic vapor separation membranes are rubbery polymer membranes. The separation process relies on solubility selectivity, where differences in the solubility and permeation rates of organic vapors in the membrane are utilized. Gases with larger molecular weights and higher boiling points (e.g., ethylene, propylene, chloromethane, vinyl chloride, butadiene) dissolve more readily and permeate faster through the membrane. This enables their separation from gases with smaller molecular weights and lower boiling points (e.g., H2, N2, CH4).
Driven by the pressure difference across the membrane, the feed stream entering the membrane system is divided into two streams: permeate and retentate. The permeate is enriched with organic vapors, while the retentate is purified light component gases.

Application case
Ethylene Recovery in Ethylene Glycol Production Unit
methane as a stabilizing gas. To prevent the accumulation of argon (Ar) introduced with the oxygen from air separation, a portion of the recycle gas needs to be vented, leading to losses of ethylene and methane gases.
Membrane Separation Recovery Technology Features:
* Ethylene recovery rate greater than 85%
* When methane is used as a stabilizing agent, methane recovery of over 50%
* Ethylene recovery rate greater than 85%
* When methane is used as a stabilizing agent, methane recovery of over 50%
Recovery of Tail Gas from Station and Bridge Loading and Unloading
compression/condensation, followed by gas-liquid separation to separate the liquid-phase products. The non-condensable gas from the separation tank enters the membrane separation system, where permeate gas and vacuum desorption gas return to the compressor inlet. The tail gas from the membrane separation system is enriched nitrogen gas, with non-methane hydrocarbons less than 15q/㎡ directed to the nitrogen buffer tank or further sent for adsorption purification <60mg/m, achieving an overall hydrocarbon recovery rate greater than 97%.
Recovery of Light Hydrocarbons in Polyethylene Production Processes
In BP's fluidized bed process, where ethylene monomer conversion rates are not 100%, the membrane separation system recovers over 85% of emitted ethylene, maintaining production stability and efficiency by recycling gases effectively.
Polypropylene Production: Recovery of Propylene
Polyolefin Plant Tail Gas Recovery: Olefin and Nitrogen Recovery
