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..
Evaluate challenges in meeting clean-fuel specifications with heavier crude
At a Saudi Aramco refinery, a revamp was planned for processing a different crude oil blend to meet Euro 5 diesel and gasoline specifications. The refinery, which processes semi-light crude oil, is sc..
Optimize value from FCC bottoms
Fluid catalytic cracking (FCC) is one of the most versatile and profitable upgrading processes in a refinery. FCC has maintained its place in the refinery through a series of evolutionary changes to m..
HP Viewpoint: Refiners have a new learning curve with shale oil
We’ve all heard the news reports: “Shale resource developments have the potential to make the US energy independent for the first time since 1952.” The long-term impact of shale resourc..
New residue-upgrading complex achieves Euro 5 specifications
In late 2010, Grupa LOTOS SA completed construction of a major residue-upgrading project at its refinery in Gdańsk, Poland. Its 10+ Program was designed to unlock a step change in the facility’s long-term profitability. After two years of operating, this project has had a profound effect on the refinery’s economics.
