Brewers’ spent grain (BSG) is the most significant byproduct of the beer-brewing industry, making up 85% of the total waste. Globally, about 36.4 million ton/yr of spent grain are produced. This spent grain is typically discarded after its primary use…
New packings and trays encourage effectiveness and energy efficiency in traditional and emerging applications Equipment for distillation, absorption, stripping, extraction and phase separation plays a major role in the chemical process industries (CPI). However, separation processes are notoriously energy intensive,…
Most modern chemical processes require some means of rejecting heat for maintaining process efficiency, product quality and plant safety. Examples of heat rejection include cooling crystallization liquid, cooling reactor effluent, condensing material from a distillation column and cooling steps in…
Understand and follow these tips to ensure accurate and reliable temperature values Even though electrical thermometers are used quite frequently in chemical process industries (CPI) plants, people often underestimate just how wrong the temperature displayed can be if these measurements…
Thyssenkrupp Uhde GmbH (Dortmund, Germany) and Johnson Matthey plc (JM; London, U.K.) have signed a Memorandum of Understanding to jointly offer a fully integrated low-carbon (blue) ammonia technology, building on a nearly 25-year ammonia relationship between the companies. In the…
Cespa (Madrid, Spain) has selected Siemens Energy AG (Munich, Germany) for the supply of 100 MW) of proton-exchange membrane (PEM) electrolysis technology for green hydrogen production at its La Rábida Energy Park in Palos de la Frontera (Huelva), southern Spain.…
Thyssenkrupp nucera AG & Co. KGaA (Dortmund, Germany) is the preferred supplier of a 300-MW electrolyzer for Cepsa’s (Madrid, Spain) green hydrogen plant in Spain. Under an agreement, announced at the World Hydrogen Summit in Rotterdam, the Spanish energy company…
RO Membranes Toray Industries, Inc. (Tokyo, Japan; www.toray.com) has developed a highly durable reverse osmosis (RO) membrane that is said to offer double the resistance to cleaning chemicals of conventional counterparts. This reduces performance degradation from membrane wear and simplifies…
Hydrogen chloride is an important byproduct of the chemical industry, with over 9-million ton/yr generated by industrial chlorination processes, such as the production of chloromethanes and polymers (polyurethanes and polycarbonates). Although HCl can be easily recovered by gas scrubbing with…
Nanocellular graphene (NCG) is a specialized form of graphene that achieves a large specific surface area by stacking multiple layers of graphene and controlling its internal structure with a nanoscale cellular morphology. Although the material has the potential to improve…
