Maintenance and Operations
Correctly Estimate Compressor Installation Cost
By Amin Almasi, Rotating Equipment Consultant
Installation cost typically amounts to around 7–11% of the total cost of the compressor unit, but compressor size, capacity and location significantly impact the installation cost. A linear cost estimation approach can prove useful.
Solids and Fluid Handling
Consider Air Seals
By Tom Horner, Inpro/Seal
Packing or mechanical seals typically are used on rotating equipment. However, air seals often may offer advantages. They have no contacting parts to wear and require less maintenance but pose some issues of their own.

3D Visualization Makes Real Progress
By Seán Ottewell, Editor at Large
Immersive high-fidelity 3D visualization, a staple of today's video games, now is starting to play a role in the training of operators and maintenance staff at plants. Here's a rundown of some initiatives already underway.
Making it Work
Plant Improves Root Cause Analysis
By Mike Guidry, Axiall
When serious problems or incidents occur, plants usually try to find the root cause but often undermine the analyses because of inconsistencies in how they are done. An Axiall plant has taken steps to achieve consistency.
Use Affinity Laws With Care
By Andrew Sloley, Troubleshooting Columnist
Affinity laws relate speed, head, capacity and power for different diameter impellers in a centrifugal pump. They allow quick estimates but always remember actual performance will vary, especially if an impeller is cut down.
Audit Energy on a Regular Basis
By Ven Venkatesan, Energy Columnist
A plant should conduct a quick walk-through audit as a first step, followed by a comprehensive audit to more fully evaluate the savings identified in the quick audit. Maintaining energy cost control requires periodic audits.
