Ethylene propylene diene monomer (EPDM) rubber is a terpolymer elastomer derived from ethylene and propylene, along with small amounts of a non-conjugated diene as a third monomer (Figure 1). With a completely saturated polymer backbone, this random elastomeric copolymer exhibits…
Predictive maintenance (PdM) programs can provide advanced warning of equipment problems and potential failures. This one-page reference provides brief descriptions of six common predictive maintenance methods. Infrared thermography Continuous monitoring of equipment temperature over time has the potential to identify…
Batch high-shear mixers equipped with the Solids/Liquid Injection Manifold (SLIM) Technology (photo) deliver powders in an efficient manner for quick wet-out and complete dispersion into low-viscosity liquids. In a conventional rotor/stator mixer, materials are continually drawn from below the mixing…
Operational troubleshooting guidance is provided for several scenarios involving trapped non-condensable gases in distillation towers Non-condensable gases are often present in distillation towers, either expectedly or unexpectedly. When they do appear, or when the quantity of non-condensable gases varies from…
A rigorous and structured approach to determining the potential value of powder testing techniques in solids-handling applications can improve powder characterization and processing Many chemical process industries (CPI) sectors face growing pressure to measure and control powder properties more effectively,…
Solids-handling processes and downstream process steps can benefit greatly from carefully controlled particle characteristics. Presented here is guidance on how agitation agglomeration techniques can achieve desired particle properties Throughout the diverse sectors of the chemical process industries (CPI), the ability…
The complete product line of this company's stainless-steel constructed NSF/ANSI 61-certified automatic Flo-Trol valves (photo) are now available. The most recent additions to the Flo-Trol flow-regulator line includes 3/8- through 3-in. models, and standard flow range offerings from 0.19 to…
A mixed-salt process (MSP) designed to reduce the costs and increase the energy efficiency of removing carbon dioxide from post-combustion fluegas is advancing in two related projects. In the first, a 10-MW engineering-scale demonstration plant for the MSP is under…
Drain valves comprise up to 20% of all valves in a typical processing plant. But cleaning them is costly, difficult and time-consuming due to long cleaning cycles and the risk of pressure shocks. The new ThinkTop pulse seat clean (photo)…
This company is launching the first standardized electrolyzer suitable for mass production. The EL 4.0 (photo) is a fourth-generation anion-exchange-membrane (AEM) electrolyzer the company has been developed since 2017. The new version is smaller, lighter and ISO 22734 certifiable. The…
