Evaluating thermal expansion and overpressure protection.
Facilities can make effective decisions related to incident response and training by asking the right questions well before a spill or release occurs
how far has Six Sigma come in the chemical industry? Has it really made an impact in processes overall? Where will it take chemical producers in the future?
When qualifying valves for a pressure-reduction application, chemical plant engineers must consider several factors. Initially, they must determine whether or not the application requires a control valve to be effective.
Although it often is not given the attention it deserves, the design of the system piping attached to a centrifugal pump can greatly influence the pump's performance and reliability.
Process knowledge systems employing wireless technologies can deliver true benefits to chemical manufacturers
Applications benefit from more precise dosing and improved control. Read this article to learn why.
Part 2: Scaleup, simulation and new technologies
Many plants stand to benefit from these recently commercialized developments
The brave new world of RFID
Computational fluid dynamics (CFD) is helping to generate million of dollars of savings in chemical process applications. It gives process engineers a more complete understanding of the internal operation of individual unit operations.
These formulas for determining the actual fluid content of partially filled vessels address tank shapes not covered in a previous article.
One set of PID controller tuning coefficients offers no real advantage over another, although some people may think otherwise.
Gaskets are critical but often-neglected components of plant piping systems. They may be unimposing and modest-cost items, but they play an important role by keeping process fluids inside pipes and equipment. Misapplied gaskets lead to leaking flanges and potentially severe safety, ...
Newly mandated pharmaceutical pretreatment standards imposed by U.S. EPA and adopted by the city of Albany, Ore., have led Synthetech Inc. to install a wastewater treatment system. The new system not only enables the company to meet Federal and local pharmaceutical pretreatment standards, but ...
This article discusses key parameters for cartridge filter systems, to show how design choices affect costs and to identify various cost elements impacted by cartridge filter choice.
Collaboration extends Its reach -- The step change occurring in engineering technology is being driven by the latest capabilities of design and operating software to exchange these data.
Residue curve maps (RCMs) can be employed in a variety of ways, including system visualization, evluation of data, and process synthesis, modeling and troubleshooting
A combination closed-loop optimizer and G2 expert system allowed a largy chemical company to save more than a million dollars in reduced overall energy demand.
A reader has a plug-flow reactor whose temperature is starting to cycle. The company tried to tuning both controllers but saw no improvement. Read about potential solutions to this reader's problem.
Critical evaluation can enable you to turn up capacity and improve performance. This article presents some ideas to help you evaluate your process to see whether it offers exceptional revamp opportunities.
Process simulation historically has taken place within proprietary modeling environments. However, the ability of simulators to more accurately handle demanding tasks continues to evolve.
Information about heat transfer fluid (HTF) systems and the specifications for applicable fluids can be retrieved directly from the web sites of many HTF manufacturers
In plant operations, one device that can represent significant cost is the sensor, particularly one used in a harsh application. Such sensors are critical probes that gather and deliver key data, and are often exposed to or immersed in corrosive solutions and subjected to high operating ...
