In our prior post, we talked about using variants of the classic PID algorithm in order to control vacuum processes. In the simplest form, the PID control loop can be reduced to a P-only, or 2-point, algorithm. For example, by…
Testing and characterization techniques are rising to meet the demands of increasingly complex materials and applications Ensuring the integrity of materials is essential in the chemical process industries (CPI) for the continued maintenance of long-lifetime process equipment like vessels and…
This column is based on a report published by Intratec titled “Carbon Fiber Production from Pitch — Cost Analysis.” The report can be found at: www.intratec.us/analysis/carbon-fiber-production-cost. Carbon fibers (CF) are defined as fibers containing at least 90% carbon by weight,…
Establishing good control over vacuum processes has numerous benefits, such as helping to improve process yields, achieve more repeatable results, and reduce process times. And there are several options for controlling vacuum processes to achieve these various benefits. This post…
In part 1 of this white paper, we reviewed the general advantages of using dry, chemical-resistant diaphragm pumps for process scale-up applications. In part 2, we will delve into the process of configuring the mini-plant in order to realize the…
Engineers can make better use of the results of process simulations by automatically exporting data into heat and material balance tables in Microsoft Excel Chemical engineering projects require process simulation to validate the chemical reactions and mechanical operations of the…
An overview of the codes and standards that are most pertinent to chemical processing facilities Moving a process fluid from one stage of its processing cycle to the next requires the transfer of fluids between pressure vessels, through pressure piping…
Introduction Historically, mini-plants have utilized oil-sealed rotary vane vacuum pumps as a vacuum source because they provide relatively high flow rates and because they can reach relatively deep vacuum levels, such as 10-3 mbar. The same can be said of…
VACUUBRAND's dry, chemical resistant pumps provide an ideal solution for use in process development, scale-up work, and kilo labs. With no sealing fluid to replace, our dry pumps provide a low maintenance, low operating cost alternative to oil-sealed rotary vane…
Presentation. Pretty simple, right? It’s a liquid, seal it in containers in a range of sizes. Yes, it seems simple, but there are a few complexities. Here’s a summary of delivery presentations for Paratherm products, which include heat transfer…
