EDIBON has supplied each plant mounted inside a standard 40-foot open-side container. The containers are insulated and have air conditioning, lighting and air extraction systems. The containerized solutions offered by EDIBON provide great versatility as it allows to change the location of the plant in a simple way and to transport it to any place in the world by truck or ship. In addition, inside the container there is a control room isolated from the rest of the plant that allows the operator to work comfortably through an HMI connected to the PLC that controls the entire process. The plants supplied are located in industrial environments, therefore, it is also possible to control the plant remotely from the control room or from a computer via internet.
The CO2 capture process starts with an exhaust gas conditioning. This conditioning consists of a series of stages summarized as follows: flow regulation using a pneumatic globe valve, cooling of the stream using finned tube exchangers and compact gas-to-gas recuperators, washing of the gases in a water-based wet scrubber, drying of the stream using a silica gel bed and finally, removal of pollutants (CO, VOCs, NOX and SOX) thanks to a specific activated carbon bed. The plant includes a parallel bed system and a desiccant regeneration system that allows a 24/7 continuous operation. After stream preparation, the exhaust gas is fed to a pressure swing adsorption system (VPSA) consisting of three parallel columns. The adsorption process methodology together with a MOF material specially designed for this application allows very high CO2 recovery and purity values to be achieved.
