Improve Gas Processing Economics Through Nitrogen Rejection Unit Optimization
Cryogenic nitrogen rejection units (NRUs) play a critical role in gas processing operations. In addition to helping meet pipeline reid vapor pressure (RVP) specifications and reducing emissions, removal of inert nitrogen from the raw stream reduces transport volume...
An Overview of Driver Options for Natural Gas Liquefaction
When it comes to natural gas liquefaction, selecting the right machinery to drive refrigeration compressors is critical. There are generally four types of drivers LNG operators can choose from, each of which possesses unique characteristics that make it more or less...
The Importance of Sizing in Stabilizer Column Design
Front-end liquids handling typically represents one of the more energy intensive steps of natural gas processing operations. Stabilization towers, in particular, can be especially demanding in terms of energy consumption -- making them an important area to evaluate...
The Impact of Temperature and Concentration on Amine Treatment Unit Efficiency
Lean amine temperature has a significant impact on the overall efficiency of the natural gas sweetening process. Determining the optimal temperature of lean amine entering the absorber can be a rather difficult task, as it requires careful evaluation of multiple...
An Overview of Triethylene Glycol (TEG) Dehydration
Triethylene glycol (TEG) dehydration is the most commonly used method for removing water vapor from raw natural gas and natural gas liquid (NGL) streams. It is performed for a number of reasons, the two most important of which are to dehydrate raw gas so that it meets...
Is South America the New Frontier for Oil & Gas Development?
South America has been the topic of exploration and production (E&P) conversation in the Western Hemisphere. The region’s hydrocarbon potential holds approximately a fifth of the world's oil reserves with considerable shale gas potential, which can significantly...
One-Stop Shop with Turnkey EPC Contracts
Now more than ever, the terms “cost savings” and “cost optimization” are on the proverbial lips of every oil and gas firm in the industry. Many companies are looking for ways to streamline operations to reduce risks and associated costs. One such method is through EPC...
Causes of Corrosion in Amine Units
Corrosion within an amine gas-treating plant is problematic because it can result in unscheduled breakdowns and outages. Free acid gas and high temperatures, among other reasons, are often cited as significant corrosion failures in amine units. In refineries, amine...
