In chemistry, catalysis is a means of accelerating a chemical reaction between various chemicals. In a broader sense it denotes any object, activity or event that accelerates or triggers a change. In recent years the chemicals industry is catalyzing change across a whole range of industries and helping to make them more sustainable.

The upstream oil & gas industry suffered significant setbacks in 2015 and 2016, following the collapse of crude oil prices that had begun in mid-2014. Last year marked an inflection point in the market, and although far from complete, the much-anticipated recovery can be described as a ‘good start,’ particularly for the North American market. Current projections for 2018 suggest a continuation of this positive trend.

Non-Original Equipment Manufacturers (OEM) supply valve parts to the process industry at prices that are 30 to 40 per cent less than the list price from the original manufacturer, and claim to meet or even exceed the quality of the original parts. The first part is certainly true, but the quality claim is questionable at best.

This case study shows how collaboration between a leading producer of sealing materials and a high-end valve manufacturer has led to extremely efficient valve isolation solutions for refineries.

Financial constraints in the oil and gas industry are, more than ever, driving demand for reliable products and professional service with a quick response time. Duxvalves has responded by developing a new range of actuators which have the features required for control and choke valve actuation in a variety of sectors.

Optimal process control depends on multiple components working properly. However, positioners, actuators, and valves are the only pieces of equipment that move, which means they’re often the weak link of the loop. This movement causes problems such as hysteresis, stiction, and increased response time, reducing the overall control loop performance. Proper actuator selection is necessary to address these problems, because actuators are at the center of every moving part of the control valve.

Adding electronic instrumentation and automation to a water management system can provide enormous benefits, but it can seem daunting when first moving from a purely hydraulic system. While there are many instrumentation and automation options available, an electronic control system does not have to be overly complicated. Control valves are a natural place to start since they already perform much of the control in water management.

AUMA technology helping to ensure a reliable supply of drinking water for Sabah Al Ahmad Sea City, Kuwait. The electric actuator manufacturer has supplied 42 SA and SAR actuators with AC controls and gearboxes, plus four SIMA master station control systems, to a large water storage project in the city. The contract is noteworthy for its use of optical fiber communications and AUMA’s SIMA master stations to monitor and control the actuators in parallel with the plant’s distributed control sys
