CEP: August 2018

Economic operation of steam turbines requires choosing the right type and size of turbine and integrating it correctly with the heat exchanger network. This month's back to basics article describes the different types of steam turbines, offers design and rating calculations, and explains how to properly integrate turbines with the process. Other topics in this issue include: steam piping; scare tactics in safety communications; and capital projects and turnarounds.


Citizen Science in the Great Outdoors

You might recall from some of my previous editorials that I love being outdoors in nature. So the title of a recent press release was no surprise to me: “It’s official — spending time outside is good for you.” Like many people, I feel happier when I am out in nature. Now I know I’m getting healthier, too...

A Shortcut to Determine Optimal Steam Pipe Diameter

Heat Transfer
Srbislav Genić, Branislav Jaćimović
Existing models for calculating pipeline diameter are complicated and provide inconsistent and, therefore, unreliable outputs. This model simplifies the calculations to optimize the pipeline diameter and reduce overall plant cost.

Essentials of Steam Turbine Design and Analysis

Back To Basics
Jimmy D. Kumana
Effective design, analysis, and integration of steam turbines can help optimize steam supply reliability and overall energy efficiency across your plant.

Use Scare Tactics to Communicate Major Incidents

Renato Prestes, TJ Larkin
Communication that frightens employees triggers more behavior changes than similar messages without the scare factor. Including a fear appeal makes it much less likely that process safety incidents will be repeated.
