Equilibrium data and related information gathered from a liquid-liquid extraction laboratory “shake test” can provide information for process feasibility and column-type selection in the scaleup of liquid-liquid extraction processes Most chemical engineers have had the experience of dealing with problematic…
As chemical plants look for ways of maintaining operational excellence and productivity at a reduced cost, naturally they will look at new instrumentation technologies that will give them a leading edge over competitors. When it comes to gas measurement, the…
In a first-of-its-kind endeavor, a hydrogen-fluoride-based alkylation unit producing linear alkyl benzene (LAB) is being converted into a solid-bed alkylation unit that employs UOP’s (Des Plaines, Ill.; www.uop.com) Detal-Plus alkylation technology for LAB. LAB is used in the production of…
The complex demands of oil-and-gas production often require the development of customized chemical technologies, and CPI companies are rising to meet these challenges The oil-and-gas and chemical process industries (CPI) are interconnected in that the oil-and-gas sector provides many of…
New pump technologies offer better containment and reliability to keep product flowing safely and efficiently Because moving hazardous or high-value product through the process in a cost-effective manner is the name of the game in today’s chemical process industries (CPI),…
This column is based on “Acetaldehyde Production from Acetylene,” a report published by Intratec. It can be found at: www.intratec.us/analysis/acetaldehyde-production-cost. Acetaldehyde (also known as ethanal) is an industrially important, highly reactive aldehyde, mainly used as chemical intermediate in the production…
pH is a critical parameter in many aspects of production: from setting the conditions for a reaction to happen, to the management of the reaction’s process quality, and from sustaining process equipment integrity, to avoiding environmental pollution and health…
This column is based on “Ethylene Dichloride from Ethylene and Chlorine,” a report published by Intratec. It can be found at: www.intratec.us/analysis/edc-e11a. Ethylene dichloride (also known as 1,2-dichloroethane, as well as EDC and DCE) is by far the most widely…
The two main barriers to widespread use of fuel cells have been securing a reliable source of hydrogen that avoids CO2 emissions, and cost — they have traditionally depended on expensive platinum and palladium catalyst materials. GenCell Energy Ltd. (Petach…
Last month, thyssenkrupp Industrial Solutions AG (Dortmund, Germany; www.thyssenkrupp-industrial-solutions.com) launched industrial-scale water electrolysis systems that make large-scale hydrogen production from renewable electricity economically attractive. The advanced water electrolyzer (diagram) features a well-proven cell design paired with an especially large (2.7…
