Up to now, the recovery of precious metals used as catalysts in chemical processes has involved the use of incineration. Now, however, a British-Swedish joint venture has developed a process which uses supercritical water oxidation instead, which provides many economic and environmental advantages. By Steve Minett and Curt Jonsson.
Research and process of new products mean, that the operator does not know all the features of the material.
An ultra-modern, integrated carpet factory in Belgium was experiencing problems in the production of raw materials. Gassing media was stopping pumps right in their tracks. Thanks to self-priming plastic-lined chemical pumps from ITT Industries' Richter unit, the plant now operates trouble free.
Agitation is important because maximum efficiency and energy saving are constant goals in chemical engineering.
Dr J E Juvet examines a newly developed advanced loop reactor technology which is made up of a reaction vessel with a high performance gas/liquid ejector to achieve high mass transfer rates.
Two new coatings are claimed to provide performance, installation, environmental and cost benefits for O-rings, together with handling advantages in automated assembly processes.
Continuous crystallisation from solution is the major separation technology for the isolation, purification and solidification of crystalline products in the fertiliser, the food and the chemical industry. Gunter Hofmann reports on the latest developments,
Larox Corporation's fully automatic solid/liquid separation solutions reduce manpower requirements, energy and wash liquid consumption, waste water treatment costs and also improve product quality and recovery.
Hans-W Mollmann investigates the problems transporting and storing of liquefied gases which normally take place at boiling point.
Unimatic's range of Electro-Thrust electric linear actuators now includes IP65-sealed versions for use in harsh operating conditions, such as applications where frequent washdowns are required, or where the cylinders are exposed to the elements or to contaminated environments.
