Energy Efficient Separations of Olefins and Paraffins through a membrane

Throughout the petrochemical and refining industry, the separation of olefins and paraffins is generally performed via distillation, a costly and capital intensive method, particularly for light olefins. This project uses a silver-incorporated custom amorphous fluoropolymer membrane to separate olefins and paraffins. Compared to previous attempts using facilitated transport membranes, this membrane has been shown to have very good longevity in laboratory settings and has been tested with reasonably-expected process poisons.

Advanced Nanocomposite Membrane for Natural Gas Purification

Processing natural gas is the largest industrial application of gas separation membranes. Membranes occupy 10% of the ~$5 billion worldwide annual market for new natural gas separation equipment, with amine absorption accounting for most of the rest. While widely used, amine systems suffer from corrosion, complex process design, and equipment often unsuitable for offshore gas processing platforms. Amine systems are also less efficient than membranes at high CO2 concentrations.

Efficient Chemicals Production via Chemical Looping

This project will develop chemical looping technology (CLT) into a general process intensification (PI) strategy for modular upgrading of natural gas to commodity chemicals. Nonoxidative upgrading of methane, ethane and propane to alkenes and aromatics is often limited by equilbrium. CLT is an effective PI strategy to circumvent such limitations by either reactive separation or selective oxidation of a subset of products from the reaction mixture to restore the thermodynamic driving force.

Intensified Commercial Scale Production of Dispersants

This project will demonstrate conversion of a large-volume chemical commodities process from batch to continuous processing. It is focused to create an order of magnitude reduction in equipment size (and associated capital cost) by transitioning the traditionally batch production of dispersants, specifically succinimide dispersants, into a continuous process. Succinimide dispersants are a relatively large volume family of products that vary by molecular weight, and structure.
