Pressure Swing Membrane Absorption-Permeation Separation of VOCs From Nitrogen

在本SGER项目中，将演示和检验变压膜吸收-渗透(PSMABP)技术对挥发性有机物(VOCs)的去除。在PSMABP中，含有VOCs的空气或氮气将被引入中空纤维组件中，并通过循环过程进行分离。在氮气/空气中，VOCs将选择性地渗透到一组微孔中空进料纤维的壁上，吸收到惰性高沸点矿物油中，然后出现在第二组真空条状纤维中。该项目可以帮助行业和政府解决《清洁空气法》规定的VOC污染气流的清理问题。预计将探索的技术将克服现有技术的某些问题。

Pressure swing membrane absorption-permeation (PSMABP) is to be demonstrated and examined for the removal of volatile organic compounds (VOCs) in this SGER project. In PSMABP, air or N2 containing VOCs will be introduced into a hollow fiber module and separated by a cyclic process. VOCs in N2/air will selectively permeate the walls of one set of microporous hollow feed fibers, absorb into an inert high boiling mineral oil, and then emerge into a second set of evacuated strip fibers. This project can help industry and government to address the cleanup of VOC contaminated air streams mandated by the Clean Air Act. The technique to be explored is expected to overcome certain problems with current technologies.
