Estimating Still Column Top Temperature in TEG Dehydration Unit

In this Tip of The Month (TOTM), the effect of striping gas rate and TEG circulation ratio on the still column top temperature for regeneration of rich triethylene glycol (TEG) is investigated. Specifically, this study focuses on the variation of still column top temperature with reboiler pressure, TEG circulation ratio and stripping gas rate. By performing a rigorous computer simulation of TEG regeneration at reboiler pressures of 110.3 kPaa (16 psia) and 524.1 kPaa (76 psia), two charts for quick determination of still column top temperature needed for facilities type calculations are developed. In addition, the effect of theoretical number of trays in the stripping gas section is studied.

The Stainless Steel Family - An Overview

Stainless steel is a family of corrosion resistant steels containing chromium in which the chromium forms a passive film of chromium oxide (Cr2O3) when exposed to oxygen [1]. This phenomenon is called passivation and is seen in other metals, such as aluminium and titanium. The film layer is impervious to water and air and quickly reforms when the surface is scratched. This protects the metal beneath – preventing further surface corrosion. Since the layer only forms in the presence of oxygen, corrosion-resistance can be adversely affected if the component is used in a non-oxygenated environment e.g. underwater bolts on a platform support structure.

High Pressure Regeneration of TEG with Stripping Gas

In this article, regeneration of rich triethylene glycol (TEG) with striping gas at high pressure is investigated. Specifically, this study focuses on the determination of the required stripping gas rate as a function of the lean TEG mass percent, reboiler temperature, and the number of theoretical trays in the stripping section (NS) for a regenerator (still) column with two theoretical trays (NR). By performing rigorous computer simulations of TEG regeneration at high pressure, a series of charts for quick determination of stripping gas rates needed for facilities type calculations are developed.

The Value of Competent People

In the first article in this 2-part series, Ford Brett describes the likely cost to the oil and gas industry of the Big Crew Change –the waste of the equivalent of 20% of total E&P expenditures, or more than US $35 billion per year. In the second article, he examines strategies to confront the looming competency gap.

What does the “Big Crew Change” mean for you?

You’ve probably heard all about the “Big Crew Change.” During the next few years, about one third of today’s oil and gas professionals are going to retire. For an executive manager of an oil and gas company, that presents a huge challenge – as companies everywhere race to fill the gaps in their workforces. What does the Big Crew Change mean for you? Opportunity!

Investing in People: How to Quantify the Value of Competency Development

For all the emphasis placed on competency development, training budgets are almost always the first cut during any kind of down turn. For competency management to become more than a Human Resource Management fad it will have to demonstrate quantified financial return. This abstract outlines one approach to quantify the return on competency development investments.

For 3D concepts, 3D graphics work better than words

In the Geoscience disciplines (geology and geophysics), I have found that most course participants relate particularly well to graphic images. They are strongly visual learners. With fewer words and more images, they see more. For this reason, I have designed my courses to be as visual as possible. And in recent years I have carried this further to include a large number of graphic animations in my courses.
