REPSOL
New generation membrane technology reduces emissions

1236px-Repsol_logo

In 2018, Repsol introduced a comprehensive set of internal metrics, targets and action plans to ensure meaningful progress towards climate change mitigation.

By 2025, Repsol aims to reduce annual upstream greenhouse gas emissions by 3 MtCO2e per year, reduce upstream operated methane emissions intensity by 25% and halve routine flaring. In addition, Repsol is committed to reducing its carbon intensity by 3% by 2020, compared to 2016, with the ambition to reach a reduction of 40% by 2040, in line with the Paris Agreement.

With methane emissions reduction core to these programmes, Repsol has successfully piloted new-generation membranes in one of its offshore assets in South East Asia.

Due to high carbon dioxide content in the gas produced from the reservoir, several membrane separation trains are required to purify the natural gas to meet quality specifications. By upgrading the membranes, Repsol was able to increase the membrane system selectivity, while also increasing the methane recovery rate.

A membrane skids replacement schedule has now been established, and Repsol has already achieved a reduction of more than 70,000 tonnes of carbon dioxide equivalent. Repsol is sharing its experience as companies strive to re-duce methane emissions in their operations.
