Comparing DNBP replacement options in styrene production
The manufacturing of styrene commonly uses 2,4-dinitro-6-sec butylphenol (DNBP) as a retarder to protect against styrene polymer formation.
Safety in design during mechanical engineering
After a process engineer has completed preliminary documents such as process flow diagrams, material and energy balance, piping and instrumentation diagrams, equipment data sheets, process control philosophies, identifications of the hazardous nature of raw materials, chemicals, byproducts and final products, process equipment layout drawings (plans and elevations), unit plot plans, etc., these documents are issued to other disciplines to carry out further engineering.
Process safety incidents involving simultaneous operations
Some process safety incidents occur as the result of simultaneous or sequential occurrences of operations or activities that interfere or clash with each other.
Improve removal of phenolic and amine compounds in a sour water stripper
Joint stripping in a refinery sour water stripper (SWS) unit contributes to the concentration of phenols and total nitrogen (N) in the discharged treated water from the wastewater treatment unit.
