Distillation
Case history: Optimization of aromatics complex
Borealis Polymers executed an online optimization project at its phenol and aromatics plants in Porvoo. The plantwide application increased the output rate by 9% and greatly improved the stability of operations.
Convert heavy oil residue into synthetic fuel
Over the past several decades, oil extractors and refiners have been maximizing the production of easy-to-drill, high-quality light sweet oil, mostly concentrated on the Arabian Peninsula. With “..
Improve the isomerization of alkanes by catalytic distillation
The isomerization of light gasoline fractions is crucial to producing high-octane fuels and to reducing the benzene content in gasoline. One of the most promising options for isomerization is catalytic distillation.
Mitigate fouling in crude unit overhead—Part 3
CASE STUDYThe basis for this case study is shown in Fig. 18; it is a crude unit with overhead heat integration. This is a one-drum overhead system with heat integration and no water wash. In an attemp..
Mitigate fouling in crude unit overhead—Part 2
Up to 50% of the refinery’s entire corrosion expense may occur in the crude unit. The root causes of the fouling and corrosion issues are often linked to the basic unit configuration choices, as ..
Use APC in energy systems―Total’s Leuna refinery case study
Advanced Process Control (APC) has been used extensively to assist in operating refinery and petrochemical processes safely and profitably. However, with the constantly increasing fuel and environment..
Mitigate fouling in crude unit overhead—Part 1
In a refinery crude distillation column, up to 40% of the total heat removal may be found in the tower overhead condenser. The quantity of duty available makes heat integration (HI) between the column..
Update: Russia’s capacity and modernization program
Since 2008, Russian regulations regarding the crude oil and refining industry have changed substantially. At present, Russia has 22 large refineries, each with an individual throughput capacity exceed..
Consider accurate feed characterization with improved simulation methods
Assay definition is crucial for accurate process simulations. The performance of process simulators depends on the feed definition to the processing unit. Modern analytical laboratories can offer comp..
Optimize slop-wax bed height in the vacuum unit
The vacuum distillation (VD) unit in the petroleum refinery separates the heavier fraction of crude oil from the atmospheric distillation unit (ADU) into light vacuum gasoil (LVGO) and heavy VGO (HVGO..
