CEP: February 2017

The February Back to Basics article provides an overview of the centrifugal compressors used in ethylene plants. It describes their operation, clarifies some typical industry jargon, and explains the differences between the units used for cracked-gas compression and refrigeration services. Other topics in this issue include data science, scale calibration and Qatar's Chemical Industry.


Together Everyone Achieves More

One reason I love my job so much is the CEP editorial staff. Publishing CEP is truly a team effort. While each editor has individual responsibilities, we work together in many ways — from brainstorming ideas for the cover, to serving as a second set of eyes for another’s article, to taking on extra tasks to help ease a coworker’s heavier-than-normal workload.
