Get the most out of your heat exchanger by evaluating the trade-offs between a one-time expenditure and reduced operating expenses, increased income, and/or longer operating life span. Brendan R. O'Donnell - Bruce A. Barna - Chris D. Gosling -
Are you feeling overwhelmed by the daily influx of memos, letters, reports and journals? These tips will help you develop a systematic method for dealing with the endless stream of material that is essential to your job.
Sterilization-in-place (SIP) systems are essential to the operation of many pharmaceutical and biotech facilities. This article reviews design considerations, selection criteria and performance expectations for control valves, regulators, isolation...
With the simplifying assumption that all of the noncondensable gases exit via the vapor stream, material balances and equilibrium calculations can be used to determine the compositions of the emissions streams leaving a control device.
Employment negotiations begin even before a job offer is extended. Having a clear plan of action, and an understanding of your objectives and those of your employer, will help you make the most of this important process. <br>
Realistic steam prices are necessary for the efficient operation of a chemical production site, both to allocate realistic costs to the different businesses on the site and to provide a true economic incentive for energy conservation.
As with previous emerging technologies, there have been uncertainties and concerns about the environmental and health risks associated with nanotechnology. This article reviews some of the ongoing efforts to better understand and characterize...
Learn about Physical and Chemical Equilibrium for Chemical Engineers, 2nd Edition; Chemical Thermodynamics for Process Simulation; and Piping System Fundamentals: The Complete Guide to Gaining a Clear Picture of Your Piping System, 2nd Edition.
Continuous crystallizers serve a wide range of applications in the chemical process industries. Optimize system performance by heeding these practical design and operating principles, which apply to the forced circulation (FC), draft-tube-baffle (...
ASME codes and standards govern the design, fabrication, testing and certification of high-pressure dust collector vessels. This article will assist you in working with a code vessel designer and/or manufacturer.
Dynamic process modeling based on non-uniformly sampled data and multiple sampling runs, even for nonlinear systems, can be performed using spreadsheet implementations of the weighted-least-squares (WLSQ) and Runge-Kutta WLSQ methods.
Global teams can maintain their effectiveness by using the right communication tools, following good communication practices, working at building and maintaining trust, and taking cultural differences into account.
Even with the use of costly corrosion-resistant alloys, metal contamination continues to occur in the biologics industry, thus reducing product yield and activity. Fluoropolymers are emerging as a viable solution to this problem.
