Annex XII - Membranes as energy-efficient technologies for Separation of Hydrocarbons

From both the technological and application points of view, separation technology is a very broad field. Molecular membrane separation (a membrane is a partially selective barrier for transport of matter) is seen as one of the most promising and energy-efficient separation technologies. In practice a reduction of 40-60% of primary energy consumption is anticipated in key molecular separation.

The urge for energy efficient separation technology highlights the need for dissemination of results from different research areas and different countries. Regular assessments of R&D priorities and gaps, as well as comparative analysis of individual technologies are important to identifying the barriers that hamper implementation of these technologies. The Annex aims to be a facilitating platform for these activities.

Objectives of the Annex:

1. The organisation of a discussion platform for the dissemination of results in membrane separation. To enhance focus and priorities in the field of energy efficient membrane separations, road mapping exercises will be stimulated. This will lead to technology assessments and initial estimates of energy savings potential.

2. Coordination of research efforts. Based on an initial screening, olefin/paraffin separation and natural gas and biogas production were selected as focal point for this platform.

The Annex is divided into three subtasks:

Subtask A. Road mapping and focusing activities

Subtask B. Natural gas and biogas production

Subtask C. Olefin/paraffin separation
