CIONEX CO2 Capturing & Reuse Process

CIONEX CO2 capture using supported amine sorbents provides a low-cost alternative to the conventional amine scrubbing of CO2 capturing technology. This process is anticipated to have lower operational costs, environmentally friendly as well as a lower capital investment than the conventional amine scrubbing technology. Application of this novel capture process could potentially bring the thermal energy requirement of the capture process down almost 50% mainly due to the reductions in the sensible heat energy penalty of the CO2 capture process.

APM CIONEX provides the novel sorbent-based capture process comparing with the performance of a MEA-based capture facility, which is using chemical solution for CO2 absorption. The Ion-Exchange resin material inside the adsorber column is put into absorption of CO2 and is heated in the desorption chamber up to the desorption temperature. After desorption of CO2 the resin material leaves the desorption chamber and passes through the heat exchanger, before it is recycled back to the adsorber column.

CO2 Reuse

The industrial use of CO2 as feedstock for the production of chemicals could contribute to keeping captured CO2 out of the atmosphere. Although underground geological and ocean CO2 storage provide huge capacity for storage, the higher investment cost and potential risks to ecosystems are the bad effects on achieving carbon neutrality. Soil and seawater contaminations are involving the political concern.

CO2 could be applied as the feed for algae framing. Together with ammonia (NH3), they are the two major ingredients to produce the Urea Fertilizer and the carbonated salts such as ammonium carbonate and washing soda.

Ammonium or sodium carbonate is now exclusively manufactured by the Solvay Process. In this process CO2 and ammonia (which can reused by APM RPB reactor ) are passed into a cold saturated solution of sodium chloride. In the reactions which occur sodium hydrogen carbonate is formed which is only very slightly soluble in the presence of sodium ions, is almost completely precipitated. It is removed by filtration and ignited to produce sodium carbonate.

Urea is widely used in the fertilizer industries as a rich source of nitrogen. The most common method for production of urea is a two-step reaction, producing urea from CO2 and ammonia. 

 

Another way to produce urea directly through one-step catalytic electrolysis. Such direct and selective synthesis of urea from ammonium salt and CO2 can be achieved at ambient temperature and pressure.

Algae are fast-growing aquatic organisms that are commonly found as seaweed, pond scum, and giant kelp. Scientists stated that one of the most sustainable strategies to capture and store CO2 from the atmosphere is photosynthesis. Planting as many trees as possible as quickly as possible could reduce carbon, but it would also increase food prices as the land for farming is reduced so that we must look to our oceans for solutions that are more effective and scalable.

 

Algae can consume more CO2 than trees because it can cover more surface area, grow faster, and be more easily controlled by given its relative size. algae and optimize for its growth. In addition, growth cycle of algae is easier than trees. Algae can be dehydrated and ultimately puts it to use as fuel or biomass to suit our energy application finally.
