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.
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 ..
MAN to supply compressor technology for Chinese synthetic fuels project
The site of the project is Yinchuan in the Ningxia region, where air separation plants are being built under the management of Linde and Hangyang for one of the world’s largest coal liquefaction production plants. The turbomachinery ordered will be used in one of the air separation plants.
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.
Select the right shaft-riding brushes for turbomachinery
Since the mid-1950s, much progress has been accomplished in the development, design and production of shaft-riding brushes for turbomachinery applications. The machinery includes steam and gas turbine..
HP Reliability: Fact-checking list from recent reliability conferences
Whenever HP editors attend technical conferences, their primary goals include observing industry practices, finding facts and spotting trends. Fact or fictionUnfortunately, presenters sometimes relate..
