Why do I care about phase diagrams?
In facilities operations the understanding of where the process is on a phase diagram can often help the engineer and operator avoid extremely embarrassing design and operating mistakes. The oil and gas industry is full of many “war stories” about “phase diagram disasters.” Most instances are never related back to the phase diagram misunderstanding. InContinue Reading

Where did my Compressor Power Go?
In a previous “Tip of the Month” we briefly discussed the problems of how to “name” the various regions of the phase diagram. To decide if this “naming game” can be a problem, look at Figure 1. This is a typical two-stage compressor system with intercoolers. This particular system however is being used to compressContinue Reading

Areas of Risk in the Operation or Design
In a previous “Tip of the Month” we briefly discussed the need for understanding a phase diagram in a gas processing system. In this Tip we will try to clearly define the areas of a light mixture phase envelope and the terms necessary to “talk intelligently” about the shape of a mixture phase diagram. ThisContinue Reading
