Experimental Investigation on Geologic Carbon Sequestration: Impacts of Impurities on CO2 trapping mechanisms in porous media Abstract A geological carbon sequestration activity can only be properly assessed if the real mechanism of carbon dioxide (CO2) immobilization in the pore space of spring rocks, known as traps, is considered. It's a fundamental aspect of the process. Velia sandstone's ability for capturing supercritical carbon dioxide (scCO2) was examined in this study, as well as the influence of initial immersion and flow velocity on the scCO2's capacity. Nuclear waste intake in four consecutive nuclear flooding cycles is required for two instances of scCO2 saline rearrangement, each depending on four consecutive nuclear flooding cycles with waste uptake. I was in charge of it. According to the results of these testing, brackish water injections may be excluded from the CO2 injection process up to 75% of the time. Under the experimental circumstances studied, we discovered that the underlying scCO2 immersion had a greater impact on the remaining scCO2 immersion than the salt water injection rate. The initial soak and the remainder of the soak seemed to have a consistent link, regardless of the experimental settings tried and what was said in the letter. Introduction CCS is seen as the most promising method of reducing CO2 emissions from the combustion of petroleum products. presentation. CCS (IPCC2005). If the limitations and binding structures are big enough and the environment is stable enough, deep sulfate and coal seams can be employed efficiently for CO2 sequestration (Bachu 2000). For the most significant CO2 storage limit (10000 to 10000 GtCO2) in comparison with alternative land configurations such as mature oil and gas fields and non-minable coal mines, deep sulfate springs are the best option. Here's how the risk to is calculated: Environmental hazard assessments indicate that the amount of risk is acceptable (Shukla et al. 2010). According to the Zero Emissions Plan, deep sulfate capacity limitations are predicted to represent 90% of the expected CO2 storage choices (ZEP 2007). (Bennion and Bachu 2008). De Silva and Ranjith (2012) found that the capacity limitations and CO2 capture components of deep sulfates are still inconsistent, and how these direct ecological concerns and productivity increases originate from isolation is unclear. Deep salt spring CO2 sequestration is possible with four key trapping devices: basic, fine, decay and mineral traps, respectively (Benson2008). Tight trapping uses a hair-like tension to hold CO2 in place on a pore-scale. When CO2 is replaced by groundwater flow or saltwater injection, this cycle takes place. An immobile mass of CO2 is captured by lean force at the point of water backflow. For the most part, lean fishing reflects a significant commitment to the storage of CO2 in broad geological formations. There are four CO2 capture components that all pla
