A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

A system for simultaneously preparing alcohol-free wine and high-alcohol liquor, comprising a primary membrane separation system and a secondary membrane separation system. An inlet of the primary membrane separation system is connected to raw materials, and a permeation side of the primary membrane separation system is connected to an inlet of the secondary membrane separation system; both the primary membrane separation system and the secondary membrane separation system comprise an organic matter preferentially-permeable pervaporation membrane. The method for simultaneously preparing the alcohol-free wine and the high-alcohol liquor comprise the following steps: feeding the wine produced by fermentation into the primary membrane separation system, ethanol and aromatic substances therein permeating the membrane in a vapor form to form a primary permeating fluid with alcohol content of 28-32, and a primary residual permeating fluid being the alcohol-free wine with alcohol content of less than 0.5.

The present invention provides a membrane separation system that makes it possible, by a process using a pervaporation membrane, to obtain a non-permeated fluid sufficiently suitable to be reused. A membrane separation system of the present invention includes a membrane separation device. The membrane separation device has a pervaporation membrane. The pervaporation membrane separates a fermented liquid containing a volatile organic compound and a microorganism that generates the organic compound into a permeated fluid and a non-permeated fluid. The membrane separation system adjusts a temperature of the membrane separation device so that an absolute value of a difference between a temperature T1 ( C) of the fermented liquid to be supplied to the membrane separation device and a temperature T2 ( C.) of the non-permeated fluid discharged from the membrane separation device is less than 10 C.
