Viscosity is an important property for understanding the flow behavior of liquids, mixtures, emulsions, slurries and other materials in industrial processes. This one-page reference provides a refresher on conceptualizing viscosity. Intermolecular forces Viscosity is a measure of a material’s resistance…
The HiScroll series (photo) consists of three dry and hermetically sealed scroll pumps with a nominal pumping speed of 6–20 m3/h. These vacuum pumps are characterized not only by their high performance when evacuating against atmosphere, but also by their…
The new, electronic automatic pellet-mill control system, EAPR (photo), enables this company’s machines to operate optimally with low manpower requirements and long service lives. EAPR enables optimum automatic operation of all flat-die pellet mills. It consists of a local control…
With the intelligent Aquamat i.CF separator (photo), this company has redefined condensate treatment. Available for delivery volumes up to 90 m³/min, this new oil-water separator now comes equipped, for the first time, with the Aquamat Control internal controller, which undertakes…
Presented here is a description of the Open Process Automation Standard and a progress report on its implementation by industry Open Process Automation (OPA) is an end-user company-driven industry movement to transform the industrial control-system market from one that supplies…
Emerging automation-system architectures will provide the foundation required for optimized operations across the enterprise For decades, when a person mentioned process control, most engineers’ minds went to proportional integral derivative (PID) loop control, interlocks, safety and advanced process control. Perhaps…
Onsite recovery conserves one of the most precious resources — water. A well-engineered, closed-loop recycling system can pay dividends in avoided costs to treat and discharge wastewater In Southern California, few businesses dispute the need for water conservation. In a…
Making the decision to change career paths from a technical role to a more managerial one can be difficult. Here are some considerations to take into account As a technically trained chemical engineer, career opportunities are very broad with respect…
A newly developed hydrogen compressor has a linear motor design and is hermetically sealed to increase the efficiency of H2 compression while avoiding potential problems associated with H2, such as leaks and embrittlement. The linear motor-driven reciprocating compressor (LMRC), developed…
The gas subcooled process (GSP) is a method for low-temperature separation of natural-gas liquids (ethane, propane) from natural gas. Depending on the current market prices of ethane and propane, gas processors extract ethane from the natural gas or reject it…
