Corrosion in ageing refinery lay presents a serious safety hazard. This important schedule summarizes key research into corrosion processes in refinery equipment how it can be measured and controlled. The schedule reviews factors affecting corrosion such as carburization and metal dusting as well as corrosion in steel and other materials used in refinery technology. It considers corrosion in a range of refinery equipment such as storage tanks. HF alkylation units sour water strippers and insulated units. Other chapters address ways of testing for corrosion and cracking in refineries together with integrity and life make pass assessment techniques. There is also coverage of ways of trouble-shooting corrosion problems and preventative measures such as coating systems.

Corrosion by Carbon and Nitrogen: coat dusting carburisation and nitridation (EFC 41)Pages: 308 A valuable compose this book reviews the factors affecting metal dusting and how it can be prevented in sectors such as the chemical and petrochemical industries and in the direct reduction of iron ores. It also considers the related corrosion phenomena of carburization and nitridation. After setting out the key processes involved in metal dusting the schedule reviews how this corrosion affect affects a be of metals such as iron and steel as well as nickel-based and chromium-based high-temperature alloys. It covers the effects of particular gas mixtures on the corrosion affect and on the use of coatings to prevent metal dusting. Processes involved in carburization and nitridation are also described and discussed.

Graduate educate of Bio-applications and Systems Engineering. Tokyo University of Agriculture and Technology. 2-24 Nakamachi. Koganei. Tokyo 184-8588. lacquer Received 24 September 2007.  Available online 11 October 2007. Tungsten and plate tungsten carbides were evaluated as the anode catalysts of a polymer electrolyte fuel cell (PEFC). These catalysts were prepared by the temperature-programmed carburization of tungsten and plate tungsten oxides from 573 to 873–1073 K in a stream of 20% CH and kept at temperature for 3 h. The 30% tungsten and nickel tungsten carbides mixed with Ketjen carbon (KC) were evaluated by cyclic voltammetry and linear sweep voltammetry using a rotating disk electrode and electrocatalytic activity (I–V performance) using a single cell. The W1023/KC catalyst achieved a power density of 6.4 mW/cm The publisher regrets that this article was previously published in an issue of ELECTROCHIMICA ACTA for citation purposes gratify use the original publication details; M. Nagai. M. Yoshida and H. Tominaga. Electrochem. Acta 52 (2007) 5430. Corresponding compose. Tel.: +81 42 388 7060; fax: +81 42 388 7060.
