Acid Gas-Water Content

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. These charts can be used for facility type calculations and trouble shooting.

Estimating TEG Vaporization Losses in TEG Dehydration Unit

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 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), several charts for quick estimation of TEG vaporization losses from regenerator top and contactor, which are needed for facilities type calculations are developed. In addition, the effect of contactor temperature on the TEG vaporization losses for a case study is shown.

Excellence in Workforce Development - Part 1

The SMRP Body of Knowledge is the best there is. But how do you know if your people can demonstrate their competence? How are you going to replace your retiring, experienced personnel with competent people who can perform on the job? How do you manage safety with safe work behaviors by competent people? In a growing number of societal areas, we are using ‘leading indicators’ to help people choose safer behaviors that prevent accidents.

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.
