This Small Business Technology Transfer Phase I project will develop novel chemically and thermally stable, highly fluorinated mixed matrix polymeric membranes with high selectivity. The program's objective is to apply enhanced membrane separation as an alternative to distillation separations that deal with high temperature and aggressive chemicals. Distillation is a major separation process in the chemical industry and consumes significant energy and capital costs. Many aggressive chemicals are difficult to separate by distillation. While membranes offer potential, most are limited by difficulties with aggressive chemicals and temperature limitations. Compact Membrane Systems has developed a family of perfluorinated membranes featuring high temperature capability, ability to operate in aggressive chemicals, and high flux. The chemical process industry would benefit from perfluorinated membranes with high upper use temperatures of 240ºC with improved separation factors. This program addresses this particular need by developing mixed matrix membrane having perfluorinated base polymer and highly fluorinated additives. By introducing greater quantities of additives as well as appropriate choice of additives, we expect to significantly modify flux and separation properties of the base perfluoropolymers while retaining their unique stability.The broader impact/commercial potential from this technology could reduce energy consumption in the chemical process industries. Distillation consumes one-third of chemical process industry energy. Enhanced membrane processes with superior chemical and thermal properties can be used to replace/improve many of these distillation separations. The largest market is the ethanol dewatering market. Ethanol is expected to grow to upwards of 40% of U.S. fuel. If this occurs the market is 50-60 billion gallons of fuel per year. This project could lead to an energy-efficient process to produce ethanol as well as reduce the energy consumption of the chemical process industries.

该小型企业技术转让第一阶段项目将开发具有高选择性的新型化学和热稳定、高度氟化的混合基质聚合物膜。该计划的目标是应用增强膜分离作为处理高温和腐蚀性化学品的蒸馏分离的替代方案。蒸馏是化学工业中的主要分离过程，消耗大量的能源和资本成本。许多腐蚀性化学品难以通过蒸馏分离。虽然膜具有潜力，但大多数膜都受到腐蚀性化学品和温度限制的限制。 Compact Membrane Systems 开发了一系列全氟化膜，具有耐高温、能够在腐蚀性化学品中运行以及高通量的特点。化学加工行业将受益于具有 240°C 高使用温度和改进的分离系数的全氟化膜。该计划通过开发具有全氟化基础聚合物和高度氟化添加剂的混合基质膜来满足这一特殊需求。通过引入更大量的添加剂以及适当选择添加剂，我们期望显着改变基础全氟聚合物的通量和分离性能，同时保留其独特的稳定性。该技术的更广泛的影响/商业潜力可以减少化学加工行业的能源消耗。蒸馏消耗化学加工工业能源的三分之一。具有优异化学和热性能的增强膜工艺可用于替代/改进许多蒸馏分离。最大的市场是乙醇脱水市场。乙醇在美国燃料中的占比预计将增至 40% 以上。如果发生这种情况，每年市场将消耗 50-600 亿加仑燃料。该项目可能会产生一种高效节能的乙醇生产工艺，并减少化学加工工业的能源消耗。
