Pre-Fractionation NGL Amine Sweetening

Filtration in Pre-Fractionation NGL Amine Sweetening involves separating solids from Y Grade liquids and filtering amine from hydrocarbons.

Before NGL (Natural Gas Liquids) fractionation facilities can process mixed NGL streams into pure NGL products (ethane, propane, normal butane, isobutane and natural gasoline), it needs to be treated to remove hydrogen sulfide (H2S) and carbon dioxide (CO2). This process is called amine treating, also known as amine scrubbing or gas sweetening.

NGL containing H2S and CO2 are commonly referred to as sour or acid laden NGL and amine sweetening is essential to make the NGLs marketable and suitable for transportation. H2S and CO2 need to be removed because:

  • H2S is an extremely poisonous, lethal and corrosive.
  • CO2 when combined with water creates carbonic acid which is corrosive to pipeline infrastructure.
  • CO2 also reduces the BTU value of the NGL and in concentrations of more than 2% or 3%, it becomes unmarketable.

Once the NGL stream has had the acid gases and water vapor removed, it is now classified as dry and sweet, and is suitable for sale or further processing.

Traditionally, amine sweetening is done in large amine contact towers. These are capital-intensive large-scale projects. Based on our decades of filtration and separation expertise and experience, Jiantonio Group has developed a unique compact solution for pre-fractionation NGL amine contacting that reduces the footprint of the solution, cost and time to market.
