Distillation
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..
HP Construction Profile: US Midwest refinery nears completion of major modernization project
In early July 2013, BP announced that it has completed the commissioning and startup of a new, 250,000-bpd crude distillation unit at the Whiting refinery, marking a major achievement in the multi-bil..
HP Boxscore Construction Analysis: Outlook for major revamp projects—Part 2

Consider catalytic dewaxing as a tool to improve diesel cold-flow properties
Diesel engines rely on effective dispersion of fuel to ensure efficient combustion. In cold weather regions, maintaining the fluidity flow of fuels can be difficult. Catalytic dewaxing is a selectiv..
How to select the ‘best’ fired heater for your operations
With the fluctuation of natural gas pricing, it is important to evaluate technically feasible solutions and choose the most economical alternative. Ultimately, this leads to a simpler and more cost-effective solution.
Optimize crude preheat train to balance efficiency and operability
Critical attention must be paid when designing the crude distillation unit (CDU) preheat train. Many pitfalls can easily lead to unnecessary expenditures or unsatisfactory operations. Key design crite..
Seal safety may require going beyond typical standards
Top industry professionals believe users must reach beyond typical standards in applying safer mechanical seals when hazardous and toxic chemicals are involved.
Consider both actual and virtual spare parts inventory
Globally, hydrocarbon processing industry (HPI) facilities operate hundreds of thousands of fluid machinery assets. The various service-specific internal components of these assets are supported by ma..
Consider novel CGC and front-end depropanizer system for olefins production
In the presented case study, an innovative design for an integrated CGC-DeC3 system introduces part of the heavier condensate from the early compression stages directly into the high-pressure (HP) depropanizer.
Enhance operation and reliability of dividing-wall columns
Dividing wall columns (DWCs) are an attractive option when the goals are to reduce energy consumption and capital investment for distillation processes. A major component in a DWC system is the reflux..
