Selecting a sensor for continuous monitoring involves many considerations. This article discusses the types of sensors available, their applicability and limitations, and how to choose an appropriate sensor to protect people and equipment.
Slurry agitation involves complicated processes. This article presents guidelines for understanding the rheology of cellulosic and other fibrous materials, and outlines a method for scaling up their agitation.
Operating a column under actual distillation conditions is important for obtaining commercially valid hydraulic data. This article describes how a column was modified to operate in either a production or a research mode to collect hydraulic and mass...
NOx emission standards are becoming very tight, especially in the Houston area and in Southern California. Among the technologies to meet these standards are process modifications and energy efficiency improvements, as well as advanced burner...
Effective transportation risk management (TRM) balances safety and security with operational efficiency. When developing a TRM program, use this comprehensive framework and these practical techniques to identify and screen risks.
To select the proper instrument for process monitoring, one must determine what attribute of the particle system impacts the process or product parameter of concern. Once the size region is identified, it can be tracked in-process, opening up the...
This article offers a detailed reliability-based methodology for determining the safety integrity level of instrumented systems by providing overpressure protection where arrangements of multiple pressure-relief valves are impractical to implement.
Debate over the Chemical Facility Anti-Terrorism Standards continues to revolve around whether manufacturers and processors will be required to incorporate inherently safer technology into their security plans.
Not all polymers are useful and/or processable in their natural form. Thus, functional chemicals are added to polymer resins to facilitate processing and to enhance, extend, or otherwise modify the properties of the plastic products manufactured from polymer resins. Such plastic additives represent a $4.6-billion business in the U.S.
Think of process safety management (PSM) as a project deliverable, and follow these best practices for scheduling and performing process hazard analyses (PHAs) and completing other PSM requirements during key phases of a major project.
