Industrial evaporator heat-transfer surfaces are either tubular or flat plates, packaged into a variety of evaporator types, as outlined here. Batch evaporators Batch evaporators are vessels with a heating jacket or internal coil, an overhead condenser, a condensate receiver, and…
Polylactic acid (PLA, polylactide; Figure 1) is a thermoplastic aliphatic polyester that is derived from a number of renewable starting materials, such as starch and sugarcane, via bacterial fermentation. PLA is semicrystalline or amorphous, rigid, resilient and an ultraviolet-light-resistant material,…
To withstand the harsh conditions and potential safety risks encountered in urea agricultural applications and other severe-service processes, special consideration must be given to valve construction, performance and installation Severe-service valves (SSVs) are specially designed and manufactured for critical applications…
Kaji Technology Corp. (Osaka; www.kajitech.com) and Toray Industries, Inc. (Tokyo, both Japan; www.toray.com) have jointly completed developing and demonstrating an electrochemical hydrogen pump system earlier this year. This effort was part of a project, funded by the New Energy and…
Ethylene Toyo Engineering Corp. (Chiba, Japan; www.toyo-eng.com) has been awarded a contract for a project to construct an ethylene pilot plant, using waste-derived ethanol as raw material. The project is planned by Sumitomo Chemical Co. at its Chiba Works. Sumitomo…
A new demonstration plant will significantly scale up production of sustainable textile fibers made from cellulosic raw materials. TreeToTextile AB (Stockholm, Sweden; www.treetotextile.com), jointly owned by H&M Group, Inter IKEA Group, Stora Enso and LSCS Invest, has piloted a production…
A proprietary hydrometallurgical process known as Re-2Ox —originally conceived for the production of high-grade cobalt sulfate from mineral resources — is now showing promise in the field of battery recycling. “We did some preliminary test work and the technology was…
This application note outlines how multi-dispensing on the Picus® 2 electronic pipette enables users to efficiently aliquot samples by aspirating a single volume and dispensing it into multiple equal portions. While this mode improves speed and reduces contamination risk, it…
