Acid Gas-Water Content
February 11, 2014
|
Tip of the Month
This post goes over the acid gas-water phase behavior system. Specifically, different methods of predicting water content of acid gas systems are evaluated based on experimental data from the literature. Water content diagrams compatible with the experimental data for pure CO2, Pure H2S, pure CH4 and their mixtures are generated and presented. Thes...

Estimating TEG Vaporization Losses in TEG Dehydration Unit
December 16, 2013
|
Tip of the Month
In this Tip of The Month (TOTM), the effect of striping gas rate and triethylene glycol (TEG) circulation ratio on the TEG vaporization loss from the regenerator top and contactor top is investigated. Specifically, this study focuses on the variation of TEG vaporization losses with reboiler pressure, TEG circulation ratio and stripping gas rat...

The Stainless Steel Family - An Overview
October 4, 2013
|
Tip of the Month
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 ...

High Pressure Regeneration of TEG with Stripping Gas
September 11, 2013
|
Tip of the Month
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 regenera...
