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..
Optimize vacuum ejector operations
Vacuum distillation unit (VDU) designs generally involve jet ejectors due to their low capital and operating expenses, high reliability, durability and simplicity. Once the ejector is installed and co..
HP Integration Strategies: Asset information management improves life cycle benefits for equipment
Traditionally, the various production management and asset management systems in the hydrocarbon processing industry (HPI) and other heavy industries resided in silos with separate management, archite..
HP Viewpoint: Consider integral-gear compressors in CO2 services
In 1998, the author began researching suitable technology for compressing 95 MMSCFD of “bone dry” (–100°F dew point) carbon dioxide (CO2) from 16.7 psia to 2,710 psia. The compress..
HP Engineering Case Histories: Case 72: Interaction between disciplines when troubleshooting
When troubleshooting, we can become fixated on the discipline that we are most familiar—in the author’s case, mechanical engineering. Investigating the failure of a machine may have a group ..

Overflow systems are the last line of defense
The overflow system is the last line of defense against the excessive container filling. An overflow system consists of an overflow nozzle with internal and/or external piping and, in some cases, a si..
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.
High-pressure polyethylene: Reemergence as a specialty chemical or not?
The analysis results indicate that, while investment capital for new plants favors LLDPE, plant profitability—which is a function of product slate (revenue) and cost—is, in many cases, higher for LDPE plants.
HPI Focus: New vs. debottlenecking projects
As most owners do not have adequately skilled engineering teams to study these scenarios, engaging an experienced, qualified engineering contractor to support the conceptual study is often warranted.
