Currently, there are several different thermodynamic hydrate inhibitors that one has available to choose from. One could choose to use an oxygenate, such as methanol, or a glycol, such as mono-ethylene glycol (MEG) or diethylene glycol (DEG). But what determines the inhibitors hydrate suppression performance, and which one should I choose for my inhibition needs?Continue Reading
Part 2 – Thermodynamic Hydrate Inhibitors Series Currently, there are several different thermodynamic hydrate inhibitors that one has available to choose from. One could choose to use an oxygenate, such as methanol, or a glycol, such as mono-ethylene glycol (MEG) or diethylene glycol (DEG). But what determines the inhibitors hydrate suppression performance, and which one shouldContinue Reading
Part 1. General Considerations Currently, there are several different thermodynamic hydrate inhibitors that one has available to choose from. One could choose to use an oxygenate, such as methanol, or a glycol, such as such as mono-ethylene glycol (MEG) or diethylene glycol (DEG). But what determines the inhibitors hydrate suppression performance, and which one should I chooseContinue Reading
In Part 1 of this Tip of the Month Series, a basic review of the APCI C3/MR process was provided. In addition, a brief introduction into the global LNG trade was discussed. Part 1 cited many Liquefaction Technologies available for LNG processing, showing that the most commonly applied LNG liquefaction technology was the APCI C3/SMR(MR)Continue Reading
Part 1 – A Basic Review of the APCI C3/SMR World LNG Positioning and Impact The birth of modern day LNG production and worldwide commerce commenced with the 1958 conversion of the NORGULF’S Shipping Line’s freighter, NORMANTI into the newly designed world’s first LNG carrier renamed the Methane Pioneer. The vessel was fabricated byContinue Reading
This Tip of the Month (TOTM) discusses design and operational considerations of surface facilities for unconventional light oil shales. We will address the following questions: ► Are you having vapor pressure issues in the winter? (One operator had 100,000bpd shut in for a month) ► Are your tanks venting? ►Are you getting oxygen into the feed gas of yourContinue Reading
This TOTM will discuss the phenomenon of infinite recycles and their impacts on design, troubleshooting and optimization to increase oil production simply by adjusting setpoint. As well as flaring reduction, unconventionals, identification and solutions. Question: If you have an infinite recycle of LPG in your gas processing plant, how much horsepower does your compression system need? Answer: Infinite LiquefiedContinue Reading

In this Tip of the Month, we explore how process safety competency can be identified and developed using a simple model for guidance. This TOTM is the paper that was developed by JMC Instructor/Consultant Clyde Young for a poster presentation at the Center for Chemical Process Safety (CCPS) 7th Global Congress on Process Safety inContinue Reading
