BASF’s gas-treatment technology to be used by Linde and Heidelberg Materials’ large-scale CO2-capture plant

A CO2 capture process, jointly developed by Heidelberg Materials, Linde GmbH (Pullach) and BASF SE (Ludwigshafen, all Germany), and based on BASF’s advanced OASE blue technology, will be used for the first time at a large-scale CO2-capture facility operated by…

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…

Optimizing CIP for membrane filtration plants

Membrane filtration plants are often used in the food and dairy industry to separate or concentrate substances without thermal stress. Until now, cleaning-in-place (CIP) operations for this equipment was energy- and water-intensive, requiring three or four individual cleaning steps with…

Scaleup for a hydro-organic-metallurgical process

Following a successful proof-of-concept to recycle spent lithium-ion batteries (LIBs) using reagent extracted from fruit peel waste, Nanyang Technological University, Singapore (NTU; www.ntu.edu.sg) has partnered with Se-cure Waste Management Pte. Ltd. (SWM; Singapore; www.se-curewaste.com) to scale up the technology in…

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…

LG Chem Supplies Reverse Osmosis Membranes to the Largest Salt Lake Lithium Extraction Project in China

LG Chem Ltd. (Seoul, South Korea) supplied reverse osmosis (RO) membranes to China’s largest salt-lake lithium extraction project. The company has shipped more than 10,000 RO membranes to the Guoan lithium extraction project led by CITIC Group, China’s largest state-owned…

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…

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…
