Although ammonia is still made by the near-century-old Haber-Bosch process, today’s ammonia plants bear little resemblance to those early units — now literally decorating the lawns outside BASF in Ludwigshafen, and Dechema in Frankfurt, Germany. For one thing, the…
This Mixer is Ideal for Viscous Mixing and Dispersion The PowerMix (photo) includes two separate agitation systems within one mixer. A planetary blade revolves in combination with a separate high-speed dispersion blade. Both revolve on their own axis as…
This Range of Valves Now Meets DIN Requirements The new Jamesbury polymeric-seated flanged ball valves are now available in sizes DN15 – 150 in both full-bore and reduced bore. These valves conform to PED and ISO 17292 requirements, and feature…
Pumps Centrifugal pumps with cast or forged steel casings are typically appropriate for systems with large flowrates Positive displacement pumps frequently can handle smaller flowrates of less than 100 gal/min Sealless pumps (canned motor or magnetic drive) avoid the installation…
The perfect valve to control your process has been selected. The valve will pass your maximum flow. Everything is great, right? In some cases digging a little deeper might help. The control valve usually should not be the most…
The role of valves in a process is far from insignificant. These components enable engineers to control the vitals of a process: temperature, pressure, concentration, and flow. In some cases, the failure of a valve could be catastrophic and in…
Spray technology is a powerful tool used to achieve higher levels of overall process performance. Strategic decisions in selecting and employing spray technology can yield dramatic wins. Understanding sprays, drop size, and the strengths and characteristics of nozzle types and…
This article presents the fundamental concepts of the discharge coefficient, KD, of a relief valve or a safety relief valve, and flow resistance factor, KR, of a rupture disk, and their proper use in sizing an emergency relief system. When…
As regulatory issues, environmental sensitivity, and longterm water supply concerns increase, the chemical process industries (CPI) are considering ways to reduce their water discharges. In fact, more and more companies are evaluating the viability of zero-liquid-discharge (ZLD) processes. This usually…
