Determining Overall Pump Lifecycle Costs
Beyond the purchase price, there are other optimizable costs that will help moderate pump-related expenses, when estimating pump lifecycle costs Facility managers who rely on industrial pumps for the various liquid-transfer duties in their manufacturing processes may occasionally think that…
Batch Drying: Maximizing Product Yields
Use the strategies discussed here to maximize the yields of solid products from batch drying vessels Successfully drying a wet solid in a drying vessel does not complete the operation — the dry solids must be removed from the vessel.…
Technology Profile: Nitrobenzene Production
This column is based on “Nitrobenzene Production from Benzene – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/nitrobenzene-production-cost. Nitrobenzene is an important chemical intermediate. More than 95% of nitrobenzene is used in the production of…
Facts at your Fingertips: Centrifuge Separation Capacity
This one-page reference describes how to measure the capability of a given centrifuge to separate solids from a liquid phase. G-force The centrifugal force developed by a centrifuge is expressed as a multiple of the force of gravity. This force,…
Taking Advantage of Improvements in Level Measurement Technology
Level measurement technologies have become more versatile, robust and accurate thanks to recent developments. Differential pressure and radar level measurement provide examples Level measurement applications within the chemical and petrochemical industries can be extremely challenging. Level instruments must provide repeatable,…
Sustaining Effective Process Safety Programs at CPI Facilities
The elements needed for excellence in a process safety program are known, but achieving top-level process safety performance requires sustained effort and focus Efforts to achieve excellent process-safety performance at chemical process industries (CPI) facilities are nothing new [1]. Experience…
Facts at your Fingertips: Removal of Particulate Matter from Industrial Processes
Controlling and reducing particulate matter pollution from industrial operations is a key environmental and human health objective. In chemical process industries (CPI) facilities, airborne particulate matter can result from combustion of fuels, or from process operations, such as dust from…
Avoiding SIL Misconceptions
Engineers must refine their foundational understanding of process safety in order to avoid common misconceptions about safety instrumented systems, including safety integrity level (SIL) definitions Learnings from major industrial process accidents occurring over the past half century have driven awareness…
Sampling System Design: Managing System Variables
Understanding the effect of flowrate, velocity, density, viscosity, pressure drop, friction, components and sample line sizes will help you design a sampling system The primary goal when designing an analytical sampling system is to ensure timely, accurate measurements. The sooner…
Evaporators: Design Concepts and Equipment Selection
This primer provides guidance on key aspects to consider when designing and specifying evaporators, which are used in a diverse array of industrial sectors Industrial evaporators are used to remove a solvent from a non-volatile solute to obtain a concentrated…
