Refinery operators have a pressing requirement to improve the efficiency of flow control in their plants and they want to know from the Distributed Control System (DCS) if valves are open or closed. In a typical refinery, 10% of valves are actuated and 90% are manually operated. This poses a serious problem for end-users if the DCS does not accurately know how many manual valves are opened or closed, which limits the efficiency of their business operations.

Bredel 65 hose pumps from Watson-Marlow Fluid Technology Group are now providing constant efficiency in ball-milling processes at a high-volume battery plant in China. PWE reports.

A motor control centre (MCC) sits at the heart of an industrial plant. If well maintained, an MCC can last for decades, but despite their sturdiness, even the most reliable MCCs have to be retired at some point. Pat McLaughlin, operations director of Boulting Group, explains the early warning signs that an MCC needs replacing. There are several reasons for replacing an MCC, but the most common ones include obsolescence, incompatibility with new legislation or the condition of the MCC deteriorating. Technological advancements that allow the design of intelligent, more efficient MCCs are another reason why companies sometimes opt for an upgrade.

Climate control of enclosures using water cooling is highly efficient, especially if there is already a central cold water supply available in the production plant. The new Hygienic Design air/water heat exchangers from Rittal are ideally suited to the food industry, where hygiene standards are exceptionally stringent. PWE reports.

Forklift trucks need fast and easy access to and from premises, taking goods and pallets out to, or bringing them in from, delivery vehicles. Maximum transport efficiency would be afforded simply by a hole in the wall; but of course there are security considerations and the need to prevent heat/cold transfer. Naturally, then, there are doors, and for every door there is an ideal door control system. Paul Rudge of sara LBS examines the various choices, and highlights the advantages, disadvantages and installation requirements for each.

Accurate dosing pumps are enabling Welsh Water to maintain strict phosphorus limits and reduce maintenance costs. PWE reports.

Large pumps have generally been designed to perform for decades, making them a valuable asset that requires periodic maintenance. When the performance of an older pump begins to deteriorate, it may be a sign that the impeller is worn or the volute has become corroded, and by the time this happens, finding new parts can be a considerable challenge. Fortunately, modern design techniques and manufacturing processes can create a vast range of components using reverse engineering. Jesse Jackson, customer services manager at Sulzer's Mobile Service Center in Alabama, looks at what can be done to resurrect an ageing pump asset.

Hannover Messe 2016 had a clear message: integrated industry has well and truly reached the mainstream. To prove its point, the show featured over 400 application examples of fully digitalised processes for the manufacturing and energy industries. The fourth industrial revolution, it seems, is well underway. However, to ensure that the factories of the future don’t remain castles in the air, it is necessary to shine a stronger spotlight on the benefits for industry, employees and society in general. This is precisely what the organisers of Hannover Messe 2017 (24–28 April) say it will do. PWE reports.

The climate in most industries at the moment is focused towards cost reduction to protect margins. While this is to be commended, and can offer real benefits to a business and its customers, it is important that when it comes to procurement the Total Cost of Ownership (TCO) is considered over initial cost savings. While some components may seem like the cheapest solution in the short term, they can quickly prove expensive if regular maintenance, repair and replacement work becomes necessary.
