Carbon capture storage technology called CCS is a technology for separating carbon dioxide released from a power plant (power plants) or industrial process, which has been captured and transported to a particular location. In addition, it will keep for a long time. The goal of CCS technology is clearly to reduce carbon dioxide emissions that impact global warming. At this stage, these catchments have carried out the separation process by several methods such as post-combustion. This method is usually performed in a conventional power plant. It will capture after the combustion process. The smoke coming out of the chimney will be separated by washing to generate pure carbon.
Another relevant CCS method is capture pre-combustion before the combustion process. pre-combustion technology must involve other processes such as gasification. This reactor will separate it from other fuels such as hydrogen, methane and carbon monoxide. Oxycombustion and Chemical Loop Combustion (CLC) are still under development to produce an effective and efficient method. In addition, it is transported to be moved to the storage area (storage). In the storage system, carbon dioxide can be stored in three forms: solid, liquid and gas. It depends on the purpose and the place.
Carbon dioxide can be stored at a particular depth in the earth called geo-sequestration. This method uses the injection technique in supercritical form at high pressure. This uses the site of old mining like oil fields, gas fields and coal mines. In a liquid state, it is maintained well below the surface of the ocean. There are technical methods in using this method. First, the injection of carbon dioxide by ship or pipeline to a depth of more than 1000 m, then dissolved in the liquid. Second, the injection of carbon dioxide at depths greater than 3000 m where it has a density greater than liquid. Another concept is to convert carbon dioxide into bicarbonate (limestone) and store Clara’s hydrate. The third form is to store in a solid, it will be reacted with metal oxides and will produce more stable carbonates. All of these methods will be discussed in future articles.
