Recovery of natural gas liquids with membranes from associated gas on Newfoundland and Labrador offshore production facilities
The market for natural gas has been rapidly increasing and is becoming one of the most important sources of energy in the world. Natural gas is a "cleaner" burning fuel when compared to other fossil fuels and therefore environmental impacts are minimized. Gas produced (associated gas) with...

The market for natural gas has been rapidly increasing and is becoming one of the most important sources of energy in the world. Natural gas is a "cleaner" burning fuel when compared to other fossil fuels and therefore environmental impacts are minimized. Gas produced (associated gas) with oil is largely methane with heavier fractions referred to as NGL (Natural Gas Liquids). NGL is used as feedstock for petrochemical processes or as fuel for industrial and domestic purposes. The recovery of NGL is commonly carried out at onshore oil and gas operations where space and weight are not critical design parameters. The limited space on offshore platforms makes NGL recovery a challenge. Currently, in the Newfoundland and Labrador Offshore, the associated gas is re-injected, used for power on the platforms, and some is flared but not recovered due to the difficulties to storage and transport in this remote location. This associated gas contains high levels of NGL, making attractive its recovery from the economical and environmental points of view. This thesis describes in detail the development of a membrane process to recover NGL. Different processes such as turbo-expander, absorption, adsorption, external refrigeration and membranes are reviewed and compared. As a result of this comparison, membranes are proposed as a feasible option for NGL recovery. Several membrane models are investigated.
