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. Editorial 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.

Data storage, analysis, and visualization will play more important roles in the discipline. Centrifugal Compressors in Ethylene Plants February2017Back To BasicsShane Harvey, P.Eng.Centrifugal compressors are used in ethylene plants for cracked-gas compression and refrigeration services. This article describes the basic design and operation of these compressors. Ensure Product Quality through Risk-Based Scale Calibration February2017InstrumentationSimone BudinskyMany manufacturing standards are not explicit about scale calibration and testing requirements. This article dispels some common myths about scale performance and explains how calibration and testing based on risk assessment support compliance and quality.
