Technology Profile: Benzene Production from Pyrolysis Gas
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…
Advanced ODC electrolysis reduces energy consumption even more
Around 70% of all chemical products use chlorine in their manufacturing process. At the same time, the production of this important base chemical is one of the most energy-intensive processes in the chemical industry. In order to change that, thyssenkrupp…
Oxidative desulfurization approach for hydrocarbons lowers costs
Petroleum refineries must meet increasingly stringent levels for sulfur content in fuel, but the conventional hydrodesulfurization approach requires high-pressures and temperatures. Alternative Petroleum Technologies Corp. (APT; Reno, Nev.; www.altpetrol.com) has piloted an oxidative desulfurization technology, known as Sulfex, that can…
Seals and Gaskets: Sealing the Deal
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…
Liquid-Liquid Extraction: Generating Equilibrium Data
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…
Five Reasons Why Chemical Companies Are Switching to Tunable Diode Laser Analyzer Technology
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…
HF alkylation unit converted for solid-bed alkylation of LAB
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…
Creating Custom Chemistry for Oil-and-Gas Production
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…
Improved Pump Solutions Keep Product Moving
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),…
