Low Temperature Methane Gas Water Content

Written on June 2, 2017 at 9:48 am, by

In the past tips of the month (October, November, December 2007, January 2011, February, September 2014. And April 2015), we studied in detail the water phase behaviors of sweet and sour natural gases and acid gas systems. We evaluated the accuracy of different methods for estimating the water content of sweet and sour natural gasesContinue Reading

Oil Dehydration Design Error Found in Most Designs Worldwide

Written on May 1, 2017 at 9:34 am, by

This tip of the month (TOTM) discusses how to “avoid a costly design error found in most oil dehydration systems worldwide”. Are you having reverse emulsion problems? Are you having problems meeting your discharge oil in water specifications.   An area to look for immediately is the Process Flow Diagram (PFD).  Normally systems work as theyContinue Reading

Finding Opportunities Checklist This Tip of the Month (TOTM) discusses places to look for opportunities to increase production quickly. I’ll discuss the concepts, techniques, and later where to look for and find opportunities….to be able to answer the Key Question: “Are we getting the most from our Asset?” Do you know how your asset makes money? Continue Reading

Benchmarking Against Physics – Increasing Production Today, Not Tomorrow

Written on March 8, 2017 at 9:32 am, by

This Tip of the Month (TOTM) discusses how to increase production today, quickly, and for zero CAPEX. I’ll discuss the concepts, techniques, and where to look for and find opportunities, so we can answer the key question: “Are we getting the most from our asset?”   Many companies use benchmarking data shared anonymously with otherContinue Reading

Pressure Effect on the Condensate Stabilizer Column Performance – Part 5

Written on February 1, 2017 at 10:10 am, by

This tip is the follow up of January 2017 tip of the month (TOTM) [1] which investigated a non-refluxed condensate stabilizer column having a split design where a portion of the feed is pre-heated by heat exchange with the bottoms product (see also page 352 of Reference [2]). The remainder of the feed is fedContinue Reading

Non-Refluxed Split-Feed Condensate Stabilizer Column – Part 4

Written on January 12, 2017 at 9:48 am, by

This tip is the follow up of December 2016 tip of the month (TOTM) [2] which investigated the benefits of having a water-draw and its optimum location in a non-refluxed condensate stabilizer column. That tip simulated the performance of an operating condensate stabilizer column equipped with a side water-draw tray to remove liquid water andContinue Reading

Water-Draw in a Non-Refluxed Condensate Stabilizer Column – Part 3

Written on December 5, 2016 at 3:12 pm, by

This tip is the follow up of the previous tips (April and May 2016) [1-2], which investigated the benefits of having a water-draw and its optimum location in a condensate stabilizer column [see chapter 16 of reference 3]. It will simulate the performance of an operating condensate stabilizer column equipped with side water-draw tray toContinue Reading

Charts and Correlation for Estimating Methanol Removal in TEG Gas Dehydration Process

Written on November 11, 2016 at 10:25 am, by

The TEG (triethylene glycol) gas dehydration process removes a considerable amount of methanol from a wet gas stream. if the methanol content of the wet gas is high, the dry gas may still retain high methanol content and can cause operational troubles in the downstream processes.   Continuing the October 2010 tip of the monthContinue Reading

Estimating Methanol Removal in the Gas Sweeting Process

Charts and Correlations for Estimating Methanol Removal in the Gas Sweetening Process   The gas-sweetening process by amines like methyldiethanolamine (MDEA) removes a considerable amount of methanol from a sour gas stream. Moreover, if the methanol content of the sour gas is high, the sweet gas may still retain high methanol content and can causeContinue Reading

Estimating Methanol Removal in the NGL Sweetening Process

Written on September 2, 2016 at 11:19 am, by

Similar to the gas-sweetening process, the methyldiethanolamine (MDEA) liquid-sweetening process removes a considerable amount of methanol from a sour NGL (Natural Gas Liquid) stream. Moreover, if the methanol content of the sour NGL is high, the sweetened NGL may still retain high methanol content and can cause operational troubles in the downstream processes. Provisions ofContinue Reading
