Carbon Capture, Utilization and Storage

The Paris Agreement of Dec 2015, the international treaty on climate change signed by 197 countries, recognized the need to contain climate temperature increases to <1.5 C (2.7 F) to avoid a global environmental catastrophe.

To achieve this long-term goal, countries aim to reach global peaking of greenhouse gas emissions as soon as possible and to achieve a climate-neutral world by mid-century. The stark reality is that the world needs to capture 5.6 gigatons of CO2 by the year 2050, compared to the 40 Mtpa captured today.

There are numerous approaches currently employed to separate CO₂ from gas streams, the most common being

• Absorption - CO₂ gas is chemically absorbed in a liquid solvent such as amine
• Adsorption - CO₂ gas is captured within a suitable media i.e. an adsorbent bed.
• and in a future state, membrane separation and other methods such as cryogenics or chemical looping

Once the CO₂ is captured, it is compressed and either stored or utilized. Common end-uses include urea production and enhanced oil recovery (EOR).

Each capture and utilization approach has unique filtration and separation needs that can be met using Pall technologies. Several separation needs are outlined below.

Absorption - where a solvent such as amine is used to capture CO₂

1. Feed particulate contaminants and aerosols removal with particulate filters & liquid/gas (L/G) coalescers
2. Vent gas cleanup to recover solvent aerosols and meet emissions specs with L/G coalescers,
3. Keep capture efficiency high, reduce foaming, and protect heat exchanger equipment by removing degradation products and contaminants in the solvent loop with particulate filters and L/L coalescers
4. Maintain fluid cleanliness in dehydration and compression systems with particulate filters
5. Downstream equipment and pipeline corrosion protection with particulate filters and L/G coalescers

Adsorption - where an adsorbent such as activated carbon, zeolites or metal oxides are used to capture CO₂

1. Feed particulate contaminants and aerosols removal with particulate filters & liquid/gas (L/G) coalescers,
2. Protect compressors with L/G coalescers to remove water and particulate filters to remove any adsorbent fine carryover or other contaminants,
3. Maintain fluid cleanliness in dehydration and compression systems with particulate filters
4. Pall is a materials science company and can provide media as a support for adsorbent materials
