NGL Recovery & Treatment

Sales gas specifications and monetization of valuable liquid hydrocarbons require the extraction of NGLs from the natural gas and treatment of the recovered hydrocarbons liquids in order to obtain quality, commercial-grade products.

Axens Offer

To meet this requirement, Axens offers tailored solutions, for HC dewpointing, NGL recovery and treatment of condensates and NGL’s. Axens has considerable experience in all open art and proprietary processes, including the supply of fully modularized units for natural gas dewpointing.

IFPEXOL™

IFPEXOL™ consists in using a portion of the water-saturated feed gas to recover the methanol contained in the methanol-water aqueous mixture collected in the cold process.

The methanol is stripped off and recovered as vapor in the overhead gas stream leaving the stripper, while nearly pure liquid water is drawn off from this column. The wet feed gas, containing the recovered methanol, is chilled to the required dewpoint temperature by any appropriate means (JT expansion, turbo-expander or external refrigeration).

A dry and HC-dewpointed sales gas and a HC liquid stream (NGL) are produced while the methanol-water mixture is collected separately and recycled to the IFPEXOL™ stripper.

No flash gas or low pressure off-gases are generated. Any freezing issues are avoided in the cold process thanks to the presence of the methanol that is recirculated into the cold process to inhibit the formation of hydrates or ice. A small amount of pure methanol is injected under automatic control to maintain the correct methanol concentration in the process.
