Successfully design fired heaters using ultra-low-NOx burners
Recent environmental regulations mandate that refinery and petrochemical industries reduce nitrogen oxide (NOx) emissions. Emissions legislations are constantly under review, and they differ from coun..
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..
Are you using pinch technology effectively in your daily operations?—Part 1
Pinch technology is the most rigorous, systematic and best documented methodology for process design.1–3 Nearly all optimization projects for heat recovery are conducted with some form of pinch a..
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..
North American olefin producers riding the shale gas wave
With the prospect of abundant low-cost ethane, several producers have announced intentions to build new ethylene capacity.
HP Boxscore Construction Analysis: Ethylene in evolution: 50 years of changing markets and economics
Ethylene is the key building block for the petrochemical industry. This olefin supports 70% of petrochemical industry production and is used to manufacture a wide variety of products for industrial an..
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..
Improve the performance of your existing steam system
This discussion tracks a material flow through the steam system, starting with feed and continuing with steam generation, steam uses and, finally, condensate recovery.
Improve your plantwide steam network
When optimizing an existing steam network, design and process engineers need a complete understanding of all aspects of the existing system. Accurate energy and material balances must be established.
