Visual fatigue during control room work in process industries

Permits-to-work in the Process Industries

The paper presents the collective results from a number of Safety Management System audits. The audit protocol is based on the Health and Safety Executive publication ‘Successful health and safety management’ and takes into account formal (written) and informal procedures as well as their implementation. Focused on permit-to-work systems, these have shown a number of common failings. The most c...

Multimedia Process Control Room

The centralised control rooms of large industrial plants have separated people from the processes they should control. Perception is restricted mainly to the visual sense. Only telephone or radio links provide narrow-band voice communication with maintenance personnel down in the plant. Multimedia equipment can perceptionally bring back the operator into the plant while bodily keeping him the c...

Robust PID Control in Chemical Process Industries

3 Corresponding Author Robust PID Control in Chemical Process Industries Rakesh Joshi, Kostas Tsakalis, J. Ward MacArthur, Sachi Dash Abstract Robust control design has been increasingly used in industrial settings by leading automation companies. The design procedure has evolved in the last decades and fairly automated procedures exist now for use by practicing engineers or even operators. One...
