Capacitance-type magnetic flowmeters have traditionally offered the advantage of having non-wetted electrodes and the ability to measure low conductivity fluids. However, they suffered from a sensitivity to flow noise and zero instability. Innovative technology overcomes these limitations and drives magnetic flowmeters into new areas of application, while reducing installed costs.07/18/2005
The use of spray nozzles to rapidly cool or quench gas streams is an essential application in many industrial processes, such as chemical reaction vessels, incineration, and power plant absorber gas inlet. An optimized spray quench design requires engineering analysis of the operating environment, spray nozzle performance and process reliability. This technical paper describes the design considerations for spray gas quench systems such as nozzle selection, process control, system configuration and reliability. Application of this knowledge can result in a gas quench system that operates efficiently and reliably with reduced vessel size, reduced atomization energy consumption, and minimized downtime, to achieve capital and operational cost savings for your process.09/16/2009

Welded vessels play a key role in most processes. However, few plants now have in-depth expertise in materials selection, fabrication and design of such vessels. As a result, plant staff often make errors that can be costly as well as compromise the suitability and life of the vessel. This three-part special report provides practical pointers that can help you avoid common mistakes and get the most appropriate, durable and cost-effective vessel.
- Part 1 looks at a dozen important factors to consider in materials selection, including metal selection and appropriate use of corrosion allowances and coatings. It includes pointers gleaned from first-hand experiences that can help you avoid costly mistakes and delays.
- Part 2 provides tips on how to avoid delays and achieve savings in the fabrication process. It also covers techniques that can improve vessel reliability and thus forestall costly repairs down the road.
- Part 3 gets into design issues. It condenses the 5,000+ pages of the ASME Boiler and Pressure Vessel Code into a simple guide when specifying vessels, heat exchangers and tanks. It focuses on 10 key factors.

Real Time Online Liquid Analysis to Prevent Product Loss, to Reduce Energy Consumption and to Minimize Waste Treatment Costs
Product losses and energy and waste treatment costs can be reduced significantly with Total Organic Carbon (TOC) monitoring. Reducing product loss results in savings in raw materials, energy consumption, and in water treatment charges. This means more products in production and less product in the waste water treatment plant.05/15/2012
This article discusses process filtration approach developed for each technology stage starting from batch filtration in the lab to continuous filtration for the full-scale commercial operation. Process engineers must not “jump to conclusions”, a reference from Sherlock Holmes and Dr. John Watson who prove time and again is that there is no benefit to jumping to conclusions. Therefore, laboratory / bench top filtration testing is covered for problem analysis, technology selection and pilot and demonstration scale-up. The paper continues with the filtration testing and then scale-up to the commercial size. Finally, the paper concludes with a general review of the problem-solving skills of Holmes and Watson and how these skills can be utilized by process engineers as a framework for “idea-generation” when analyzing a new process scale-up.06/02/2015
