A new process-intensification technology to accelerate the rate of enzymatic reactions has been developed by researchers from the Dept. of Chemical Engineering, University of Bath (U.K.; www.bath.ac.uk). The so-called spinning cloth disc reactor (SCDR) is based on, but extends the principles of, the conventional spinning disc reactor (SDR). The SCDR also uses centrifugal forces to allow the spread of a...

Petroleum refineries generate power from a number of sources, including cogeneration plants and steam networks. Generally, steam networks use turbines to improve operational reliability, specifically as drivers for rotating equipment. Due to increasing energy costs, it is essential to maximize the power-generation capabilities of steam networks. This article presents a spreadsheet-based optimization model...

Conventional methanation — the reaction of CO and H2 (synthesis gas) to form methane — has recently become important as a way to produce substitute natural gas (SNG) from gasified coal in regions of the world where natural gas is scarce (see Chem. Eng., August 2010, pp. 14–17). Now, an alternative methanation process, which produces CH4 directly from CO2 and H2, has been developed by...
