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.

Determining Traces of Methanol in the NGL Sweetening Process

Similar to the July 2016 TOTM, this tip will consider the presence of methanol in the sour NGL stream and determine the quantitative traces of methanol ending up in the sweet NGL, flash gas and acid gas streams.

Determining Traces of Methanol in the Gas Sweetening Process

This tip will consider the presence of methanol in the sour gas stream and determine the quantitative traces of methanol ending up in the sweet gas, flash gas and acid gas streams. To achieve this, the tip simulates a simplified MDEA gas sweetening unit by computer.

Projecting the Performance of Adsorption Dehydration Process

PetroSkills | John M Campbell’s May 2015 tip of the month (TOTM) presented a method which allows the users to estimate the decline of their adsorbent based on only one performance test run (PTR) for molecular sieve dehydrators using low pressure regeneration. This permits early formulation of a credible action plan. Site-specific factors will determines an adsorption unit’s decline curve. Consequently, conducting more than PTR is highly recommended. A poorly performing inlet separator, for example, could result in a unit exhibiting a more pronounced decline than indicated by the generic performance decline curves.
