Overpressure in a process can damage the seals in a pressure instrument’s sensor or skew the zero point. Here’s how to avoid the problem Pressure is one of the most commonly measured variables in the chemical process industries (CPI). Accuracy…
Closing off pressure upstream can minimize the need for pressure-relief systems to open, avoiding product waste and possible environmental damage Any system within a chemical process industries (CPI) manufacturing plant that is pressurized, or could experience pressure during an upset…
Determining the field performance of centrifugal compressors can benefit operation and maintenance of the equipment. Presented here is an overview of the parameters that must be measured and calculated for effective testing Compressors are used in all areas of production…
A unified gateway station and related components increase availability to improve operations and safety In information technology (IT) security circles, the most important acronym is CIA: confidentiality, integrity, availability. In industrial control security, the corresponding acronym is AIC: availability, integrity,…
A safety instrumented system (SIS) is important to ensure the safe operation of a plant. The SIS requires up-to-date sensors — recent developments in vortex flowmeters are presented here There are four key areas of concern for chemical producers that…
New technologies can provide competitive advantages compared to established processes, but significant effort is required to transition a promising concept into a commercial reality Many students study chemical engineering with the aspiration of someday inventing an innovative process that could…
The pitfalls in cost estimating that cause project overruns have been well known for decades, yet they continue to plague the CPI When I first started writing this article, I set out to summarize the mechanics of project cost estimation.…
New diagnostic devices can identify when pressure incidents happen, while keeping an eye on the condition of pressure-relief valves and rupture disks Any kind of pressurized system, from the hot-water heater in a residence to a massive chemical reactor, will…
Following a five-step process enables better outcomes for fluid system control Most often, operators and technicians will interact with components like ball valves or needle valves when adjusting a system’s operation. However, just as important to the effectiveness of a…
While some aspects of burner management systems may seem intuitive, overcoming misconceptions in their specification and design will help to elevate overall safety Boilers, burners, furnaces and fired heaters, along with any other fuel-burning equipment, are considered high-risk areas within…
