Detailed introduction

The three-inch organic vapor membrane is a roll-type organic vapor separation membrane element with a diameter of 3 inches, belonging to a small standardized membrane module. It relies on the principle of vapor permeation to achieve selective separation of organic vapor from inert gases such as air and nitrogen. It is suitable for use in small and medium-sized VOCs solvent recovery projects and in conjunction with skid-mounted complete equipment. The mixed gas containing organic solvent vapor enters the interior of the membrane element, where organic molecules undergo dissolution and diffusion on the surface of a special solvent-resistant polymer membrane, preferentially penetrating the membrane separation layer. On the permeate side, high-concentration organic vapor is enriched by the vacuum system, while inert gases are difficult to penetrate the membrane and are discharged from the retentate side, achieving concentration and enrichment of volatile organic compounds and providing conditions for subsequent solvent liquefaction recovery.

The membrane element is made of solvent-resistant composite polymer materials, capable of withstanding alcohols, esters, ketones, aromatics, halogenated hydrocarbons, and hydrocarbon oil and gas media. In the face of intermittent exhaust and concentration fluctuations, the membrane is less prone to swelling and deformation, maintaining stable permeate flux and separation selectivity. The three-inch membrane element is compact in size, with high packing density, and comes with a corresponding small membrane housing, making installation and replacement simple. It can be used individually or in multiple series or parallel combinations, flexibly adjusting the system's processing capacity. This membrane module is compatible with condensation membrane coupling processes. High-concentration tail gas first passes through a condensation unit to recover most of the solvent, and the residual low-concentration organic tail gas after condensation is sent to the three-inch organic gas vapor membrane for further enrichment. The concentrated organic vapor is then condensed and liquefied again, and the recovered solvent can be returned to the production process for recycling after simple treatment. Under medium and small air volume conditions, this membrane element can also be directly used to complete organic vapor enrichment, reducing the load on downstream processing.

The entire separation process is purely physical, without any chemical reactions. It eliminates the need for frequently replaced adsorption consumables such as activated carbon and molecular sieves, and produces no large amounts of hazardous solid waste. This process mitigates the risk of overheating and spontaneous combustion inherent in adsorption processes, thereby reducing hazardous waste disposal costs. The system is equipped with a pre-treatment unit that removes liquid droplets, dust, and corrosive impurities carried in the inlet airflow. This prevents pollutants from adhering to the membrane surface, which could lead to membrane pore blockage, slows down membrane performance degradation, and extends the service life of membrane components. Coupled with an automated control system, it allows for real-time monitoring of inlet pressure, temperature, and VOC concentration, automatically adjusting the operating parameters of the vacuum system to accommodate fluctuations in working conditions.

Three-inch organic gas vapor membranes are primarily used in small and medium-sized tail gas treatment scenarios, and are widely applied in projects such as pharmaceutical active ingredient workshops, small-scale fine chemical plants, laboratory tail gas recovery, small storage tank breathing gas, and tertiary oil vapor recovery at gas stations. The equipment occupies a small space, making it easy to integrate into skid-mounted recovery units. It can be used in explosion-proof areas, requires minimal maintenance, and is suitable for VOCs resource recovery projects that require modular expansion and have low air volume. While meeting environmental emission requirements, it recovers organic solvents and achieves resource utilization of waste gas.
