Separation Processes

Technology launched for enhancing propane recovery in GSP

The gas subcooled process (GSP) is a method for low-temperature separation of natural-gas liquids (ethane, propane) from natural gas. Depending on the current market prices of ethane and propane, gas processors extract ethane from the natural gas or reject it…

Linde and Heidelberg Materials Announce Large-Scale Carbon Capture Project

Heidelberg Materials and Linde GmbH (Pullach, both Germany) have established a joint venture (JV) under the name Capture-to-Use (CAP2U) to build and operate a state-of-the-art carbon dioxide capture and liquefaction plant. The world's first industrial-scale carbon capture and utilization (CCU)…

Using a ‘green’ oxidizer to degrade Kraft lignin into vanillin

The demand for vanillin vastly outstrips the natural resources of this flavoring agent. A chemical process is thus used to produce the required large quantities of vanillin from petroleum, which is far less expensive than obtaining the substance from fermented…

Integrated capture and conversion of CO2 to methanol

Processes that capture carbon dioxide from industrial fluegas and simultaneously convert it into useful chemicals are desirable because they offer an opportunity to produce CO2-derived chemicals more efficiently and economically than conventional approaches, where costs are driven up by the…

Battery electrode binder allows easier recycling

Recovering valuable metals, such as cobalt and nickel, from used lithium-ion batteries is emerging as a key capability because of anticipated high battery demand and material shortages. Researchers at Lawrence Berkeley National Laboratory (Berkeley, Calif.; www.lbl.gov) have developed a technology…

Facts At Your Fingertips: Fractional Solvent-Free Melt Crystallization

Fractional crystallization is a stage-wise separation technique that relies upon the liquid-solid phase change and enables the purification of multi-component mixtures, as long as none of the constituents can act as a solvent to the others. Thanks to the level…

Evonik starts up new production plant for gas separation membranes in Austria

Evonik Industries AG (Essen, Germany) has started up a new hollow-fiber spinning plant for the production of gas separation membranes in Schörfling am Attersee in Austria. The new production capacity enables the company to meet the ongoing strong demand for…

Capture ammonia reversibly with this new MOF

Production of ammonia by the Haber-Bosch process not only requires a lot of energy for the high-temperature (300–500°C) synthesis of NH3 itself, but the recovery of ammonia takes place by condensation at –20°C. As a result, large changes in both…
