Zr - fum - fcu - MOF membrane distillation under practical conditions C3H6 / Zr - fum C3H8 separation performance: (a) - fcu - MOF membrane distillation in 3 independent experiments, C3H6 / C3H8 mixed gas separation performance with feed pressure (1-7 ATM), the relationship between the C3H8 through 30 times the amount of amplification to clarity; (b) when the feed pressure more than 1 ATM, C3H6 / C3H8 separation wiped film evaporator factor of change (straight line, the right Y axis) and the percentage change (columns, left the Y axis), by putting the Zr - fum - fcu - MOF membrane found comparing with other MOFs membrane distillation, Zr - fum - fcu - MOF film is only a kind of a positive change with the increase of the pressure of membrane distillation; (c) Zr - fum - fcu - C3H6 / C3H8 Moore mixture of MOF membrane distillation separation factor and flux C3H6; (d) Zr - fum - fcu - MOF membrane distillation in continuous operation during the long-term stability of the test.

Traditional distillation and technical and economic analysis and comparison of the new hybrid membrane distillation system: (a) two system between 7 and 15 bar under the consumption of energy and the public; (b) of two systems under 7 bar cost distribution; (c) hybrid system under 7 bar cost allocation of equipment, including DISTCOL - reb for rectifying column and reboiler HEATX is compressed heat exchanger, DISTCOL - cond cbd crystallization equipment for distillation tower condenser, COMP for compressor, DISTCOL - tower for distillation tower; (d) two systems under 7 bar propylene purification cost per ton.

In order to solve the difficulties in separation of hydrocarbons, the author by building a intrinsic molecular sieve properties of continuous and stable zero defect fcu - MOF membrane distillation, proved successful mesh combination of chemical and electrochemical synthetic methods. According to the technical and economic analysis, adopt such MOFs membrane distillation can make mixed distillation system in C3H6 / C3H8 separation save about 90% energy and 67% of the cost. In addition, the electrochemical assembled continuous MOFs membrane distillation strategy, also can be customized in addition C3H6 / C3H8 and nC4 separation/iC4 mixture of other applications. In this work, through the successful combination of the directional hypothesis and practice as a rapid and high-throughput screening decarboxylation after extraction methods, to explore various polycrystalline MOFs previously undeveloped film, and choose the best candidate materials for a given target separation. This kind of simple and mild MOFs membrane preparation process for mass production to provide the excellent prospects, make MOFs membrane distillation is closer to the actual application, and made a reasonable contribution to sustainable energy future.
