Introduction to Process Sampling
Drawing process samples in open containers invites contamination and inaccuracy, and also poses serious health, safety and environmental risks. Due to the growing complexity of the industrial processes in general and...
The Need for an In-Line Oil-In-Water Monitor
Shell U.K. Exploration and Production, Aberdeen
In-line oil-in-water monitors have long been wanted for monitoring overboard discharges from oil and gas producing facilities, or for controlling water handling systems. In general their performance has fallen far below operational requirements. New techniques and steadily increasing demands for better measurement capabilities mean that systems are becoming available with the...
Humidity Sensors for Industrial Applications
It could be argued that humidity plays a part in every industrial production process. The very fact that our own atmosphere contains water vapour bears witness to this fact even if it is only that the end product is likely to be stored and eventually used in our environment; therefore, the product’s potential performance under varying conditions of humidity must be known. The extent to which humidity plays a part in any given production process...
Analyser Sample Systems
Analyser Sample Systems require experienced design engineering in order to achieve a representative, conditioned sample for analysis. Engineering design requires careful selection of materials, temperature and pressure conditioning along with correct process data. Don't forget, it is generally accepted that analyser sample systems are the victims of the Pareto principle (i.e., 20% of a system consumes 80% of the resources) since they are responsible for 80% of...

Oxygen Measurement for Combustion Optimisation - Combustion optimisation for boilers and other combustion processes has long been an important issue with increasing fuel prices. There are many end users in Australia with fuel bills inexcess of one million dollars. With typical costs of combustion optimisationsystems, and possible fuel savings in excess of 5%, pay-back periods can be veryshort. This economy is based primarily on the measurement of oxygen in the fluegas - from...
