Special Focus: Process Optimization
In this study, a methodology was implemented to predict crude distillation tower flooding events based on key process variables, including product yields, column pumparound (PA) flowrates, column temperatures and overhead reflux flowrate.
A rigorous and accurate performance evaluation of existing equipment is a key factor for the success of a plant revamp study.
Within the hydrocarbon processing industry (HPI), particularly the petrochemical sector, there remains an irritating series of reactions associated with acid gas removal (AGR) using dilute caustic soda—namely, aldol condensation reactions and their respective products.
Installation and operation of suitable contaminant removal systems, such as filtration, coalescing and adsorption equipment, have become key components in amine units.
The increased use of opportunity crude oils in refinery processing, the growing demand for light fuel, and the efficient conversion of petroleum resources to refined fuels and basic chemical raw materials have become the basis of green and low-carbon refining technology developments.
Process Control and Instrumentation
Following good experience with a generalized cut-point calculation (GCC) inferential package, which models main fractionators with side streams, French energy major Total decided to experiment with a generalized distillation shortcut (GDS) inferential package, which models simpler, two-product distillation columns.
Maintenance and Reliability
A facility’s ability to operate safely is the determining factor in its success or failure.
Project Management
For large projects, construction represents the biggest cost component and the greatest risk.
