Increased reliability, chemical compatibility and containment of sealing solutions are priorities for chemical processors Seals and gaskets may seem like an afterthought in the grand scheme of chemical processing equipment, but if you’ve ever been faced with unexpected — and…
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…
This article provides a comparative study of two approaches to protect ASME semi-elliptical pressure tanks from overpressure in the event of a fire Calculating the wetted surface area is a crucial step to protect American Society of Mechanical Engineers’ (ASME)…
This column is based on “Benzene Production from Pygas,” a report published by Intratec. It can be found at: www.intratec.us/analysis/benzene-production-cost. Benzene is the simplest and most important industrial aromatic hydrocarbon. It is a versatile petrochemical building block, and is an…
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…
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…
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…
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…
