Separation Processes

Enhanced safety in polymer production

In the Ziegler-Natta polymerization process, precise temperature measurement is critical to prevent runaway reactions and ensure operator safety. A major risk arises if a thermowell leaks, potentially exposing personnel to hazardous materials during maintenance. Endress+Hauser’s iTHERM ModuLine TM131 with Dual…

Navigating Process Development for Separation Operations

Designing new separation operations involves several key steps, including proper naming of the process steps, identifying suitable technologies and supporting studies needed for unit-operation selection Chemical engineers must be vigilant when reviewing first-of-its-kind chemical processes to ensure that processing steps…

Adapting thin-film polymers for membrane separation of liquid hydrocarbons

Thin-film polymer membranes have been very effective for industrial-scale desalination of seawater, but have not been used for separation of liquid hydrocarbon mixtures because oil-separation membranes tend to absorb oil components and swell, which eliminates their size-sieving ability to separate…

Improving Control and Accuracy for Oil and Gas Analyzers

Regulating conditions such as flow rate at input, and backpressure at the vent will result in clearer data for your gas chromatograph. In this article, learn to leverage new technology to ensure the reliability of analyzer data, and reduce failure points in…
