Tip of the Month
In continuation of Feb 2023 “Tips of the Month” (TOTM) and given the amount of investment
and interest in hydrogen, we have decided to publish a series of TOTM to explore the opportunities,
challenges, and potential solutions to hydrogen applications and uses; this is the second paper in the series.
As such, we will continue this exploration with h...

Hydrogen Series Part 1: Hydrogen Colors – What do they mean, Options for Production and their associated Challenges?
February 15, 2023
|
Tip of the Month
Low or no carbon hydrogen production, distribution and consumption is thought to be one of the primary solutions to reaching net zero for heavy industry, possibly power generation, residential use for heating and cooking, as well as transportation. Hydrogen has a high heating value, and the combustion reaction does not produce CO2. According to H...

A Short Cut Method for Evaluating Molecular Sieve Performance
February 2, 2023
|
Tip of the Month
This Tip of the Month shows how a Short Cut Method (SCM) after one Performance Test Run (PTR) may be used to estimate the life of a Type 4A molecular sieve dehydrating a water-saturated feed of natural gas.
The results of the proposed SCM have been compared with the rigorous manual calculations (May 2015 Tip of the Month) and the computer-generate...

Variation of Natural Gas Viscosity with Temperature, Pressure, and Relative Density
December 20, 2022
|
Tip of the Month
In general, gas viscosity is used in fluid flow pressure drop calculations, detailed heat exchanger calculations, and droplet settling calculations for separation. It is also used for trouble shooting and equipment sizing.
In this Tip of The Month (TOTM), several options/methods for estimating viscosity of lean sweet natural (hydrocarbon) gases as ...

Oil Field Water Scaling Case Studies
November 1, 2022
|
Tip of the Month
The compatibility or scaling tendency of effluent production waters with reservoir formation waters in the oil field will be a major factor in determining the feasibility, as well as long term planning of produced water re-injection into a specific reservoir and defining engineering solutions for the injection system and specific compatibility of t...

Determining Traces of Methanol in the Gas Sweetening Process - Updates
October 1, 2022
|
Tip of the Month
The July 2016 tip of the month (TOTM) considered the presence of methanol in the sour gas stream and determined the quantitative traces of methanol ending up in the sweet gas, flash gas and acid gas streams. To achieve this, the tip simulated a simplified MDEA gas sweetening unit by computer. That tip also studied the effect of feed sour gas temper...
