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

This tip is the follow up of the previous tips (April and May 2016), which investigated the benefits of having a water-draw and its optimum location in a condensate stabilizer column. It will simulate the performance of an operating condensate stabilizer column equipped with side water-draw tray to remove liquid water.

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

Continuing the October 2010 tip of the month (TOTM), in this TOTM we will consider the presence of methanol in the produced oil/water/gas stream and determine the quantitative traces of methanol ending up in the TEG dehydrated gas.

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 cause operational troubles in the downstream processes.

Estimating Methanol Removal in the NGL Sweetening Process

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 of purging reflux (Water Draw) of the regenerator column and its replacement with “Fresh Water” can improve methanol recovery.
