Life Cycle Assessment of Electro-submersible Pumps System Enhanced with Permanent Magnet Motor

Climate change has triggered environmental awareness around the world with the use of clean technologies that help to control the inventory of Greenhouse Gas (GHG) emissions in their operations, but the calculation of environmental mitigation requires the knowledge of Life Cycle Assessment (LCA) in the production processes. Oil Artificial Lift Systems use Permanent Magnet Motors (PMM) as a viable option in their configuration, which is why it is important to know the Greenhouse Gas Inventory of these alternatives. This research compares the Greenhouse Gas inventory for the Life Cycle Assessment (LCA) of the product of an Electro-Submersible Pumps System (ESPs) with a Normal Induction Motor (NIM) and a Permanent Magnet Motor (PMM). First, the Functional Unit (FU) and LCA were defined according to the ISO 14067:2018 standard. Then the Greenhouse Gas Inventory was carried out according to ISO 14064-1:2019. As results, 5 defined stages of the LCA were determined. 14 activities related to the LCA were found. For the Electro-Submersible Pumps System (ESPs) with MIN, 999.9 kg of raw material were calculated, 1491.66 kW/h for manufacturing, 1491.66 kW/h for storage and 5.77E04 kW/h for use. For the ESPs with PMM 656 kg of raw material were calculated, 1491.66 kW/h for Manufacturing, 1,491.66 kW/h for storage and 4.72E04 kW/h for use. A 18.99 % improvement in the GHG emissions inventory was achieved due to a substantial 18.19 % decrease in energy consumption in the Greenhouse Gas Inventory. The values showed a reduction of 18.99 % of the Carbon Footprint (CF) for the ESPs with the application of new technology. The use of clean technology through the use of PMM could be a feasible alternative in Ecuador, since LCA accounts for 96.39 % of total CF.
