Are your Condensate Stabilizers Operating at Peak Performance?
Over the past two years, Dr. Mahmood Moshfeghian has written a five part series on how to improve performance in condensate stabilizers. These articles focus on its benefits, optimum location, split feed design, using a non-refluxed condensate stabilizer and its pressure effects. To learn more about the articles in the series view the summaries and links below.
Summary: This article investigates the benefits of having a water-draw in a condensate stabilizer. In order to take into account the non-ideality of water, three-phase calculations (vapor, liquid hydrocarbon, and aqueous phases) are performed on the trays with excessive water rates.
Summary: This article presents a summary of the computer simulation results and the key diagrams for the Part 1 case study. It uses commercial simulation software to determine the optimum location in a condensate stabilizer column.
Summary: This article investigates the benefits of having a water-draw and its optimum location in a non-refluxed condensate stabilizer column. Additionally, it will simulate the performance of an operating condensate stabilizer column equipped with a side water-draw tray to remove liquid water and a stripping sweet gas stream to reduce the H2S content of a sour condensate. Using that data, it is possible to determine and report the possible locations of water-draw tray based water partial pressure along the column.
Summary: This article studies the benefit of the upstream free water knockout drum and the pre-heater used in the split-feed design.
Summary: This article studies the effect of pressure on the performance of a non-refluxed stabilizer column with the split-feed design from part 4. It presents a summary of the computer simulation results and key diagrams for the plant.
