Instrumentation/Process Automation Get the best from your GWR level transmitters by avoiding problems caused by noise and poor installation practices
Guided Wave Radar (GWR) technology has transformed the way process companies measure level in challenging applications. GWR provides an accurate and reliable measurement for both level and interface applications and, because there are no moving parts, maintenance is minimal. Critical to a successful GWR application is correct installation. This article describes the difficulties caused by application induced noise and poor installation practices, and explains how features like probe end projection, combined with robust electronics ensure a high level of measurement performance.
Plant automation – putting availability where it counts
Discussions on redundancy often overlook the fact that the real threat to plant automation availability lies in factors that are human made and can be controlled the same way. This article explains the mathematical background, the pitfalls of such calculations and show cases the faults and scenarios significant to fieldbus and how to handle them with proven in practice technology.
New oxygen sensor optimizes the brewing process
Dissolved oxygen is one of the biggest enemies of delicious beer and it must be watched continuously during the brewing process. Conventional Clark sensors are known to have their limits. They produce false readings as a result of stop-of-flow effects or after CIP cycles. To get around the problems, optical sensors which deliver more reliable results have been in use for some time. A portable oxygen meter with innovative sensor technology raises process reliability to a new level. >top
Pumps Pumping efficiency from vine to wine
Various pieces of equipment play a critical role in the winemaking process, perhaps none as critical as the role of pumps. Pumps are used for wine transfer, filtration/bottling, unloading trucks, unloading tank wagons and unloading ships, to name a few applications. When selecting the pump technology that is best suited for wine-handling and transfer, operators should identify a technology that not only has shear-sensitivity (the ability to move the wine without damaging or shearing the delicate product), and deadhead capabilities (the ability to start and stop the pumping process instantly without subjecting the wine to heat or damage from moving pump components or bypass relief valves), but can also safely transfer large solids (the must) with strong suction lift. >top
Seals Perfluoroelastomer seals withstand aggressive operating conditions
The seals are hidden inside valves and pumps and they are suitable for use as O-rings and diaphragms, preventing unwanted substance transfer on production lines. They are often susceptible to attack by aggressive chemicals, and that has an effect on failure rates and maintenance intervals. This article explains why they are an efficient sealing alternative compared to conventional elastomers perfluoroelastomers. >top
Pharmaceutical Technology Numerical simulation simplifies the introduction of continuous production
Cost pressure continues to mount in pharmaceutical production, and that trend is accompanied by the need for improved process efficiency and better product quality. Sometimes a continuous production process can help pharmaceutical companies remain competitive in an increasingly difficult market environment. The article explains how numerical simulation can simplify the introduction of continuous production techniques for active pharmaceutical ingredients (APIs). The emphasis is on system modeling and optimization.
What will tomorrow’s pharmaceutical plant look like?
What visions do experts have for the factory of the future in the pharmaceutical industry? The Vice-President of a large European pharmaceutical plant and equipment manufacturer provides answers to this question and other questions as well. >top
Bioprocess Engineering Bioreactors – the top trends at Biotechnica
The bioeconomy is booming – and the same is true for the production of bioreactors The use of all sorts of equipment ranging from huge fermenters to very compact lab devices is one the rise. Selectively chosen microorganisms and enzymes open up totally new reaction pathways. However, the challenges are immense. Process engineering, catalysis, enzyme development and microbiology must work in unison to successfully introduce bio-based techniques into production. In response to this trend, Biotechnica 2013 is organizing the special Biobased World exhibition which will provide a platform where industry and researchers can share information. We take a look around this flagship show in the biotech industry to keep you up to date with current trends and developments and discuss issues which are of vital interest to the industry. >top
Water/Waste Water Technology Remote control and automation technology in the water industry
Remote control and automation technology provides the systems needed to monitor and control distributed systems such as wells, reservoirs, sewers, pumping stations and water treatment plants from central control stations. The technology can also be installed as a retrofit using wireless or Internet links.
Process air production with highest energy efficiency
In biologically working municipal and industrial wastewater treatment plants the production of oil-free process air requires a considerable amount of electrical energy. However, an optimal solution with highest possible energy efficiency can only be achieved when the compressor performances can be adjusted continuously to the alternating consumption due to unsteady waste water quantities and degrees of pollution. >top
