Suitability of Methyldiethanolamine (MDEA) and Piperazine (PZ) for Improving CO2 Absorption Efficiency Using Rotating Packed Bed (RPB) Technology: A Modeling and Simulation Study
Abstract: Carbon dioxide (CO2) capture and storage (CCS) is an essential technology for reducing atmospheric CO2 emissions and mitigating climate change, especially in fossil-fuel power generation. However, the high cost of CCS technologies has hindered their widespread adoption. In this study, we modeled CO2 removal using a rotating packed bed (RPB) technology using Visual Fortran and Aspen Plus software. We made use of a blended amine solution including different molar concentration …

Use of Pesticides leads to Environmental degradation
Abstract: Pesticides are extensively used for agriculture but residues can reach aquaticecosystems, frequently. They are transferred from pytoplankton to fish and human, ultimately. Pyrethroid insecticides are utilized in place of organochlorine,organophosphorus and carbonate to control different forms of pests and raise yield. Pyrethroid intoxication causes cellular damage and increases freeradicals, which leads to lipid peroxidation and, ultimately, oxidative stress.To reduce damage to environment and biologicalsystems by pesticides should be played attention …

Biological Recovery of Soil Impacted by 30,000 ppm of Gasoline
Abstract: Gasoline is a mixture of low and high molecular weight hydrocarbons, which spilled on the soil due to fuel theft, causes environmental pollution. In consequence the Mexican standard, called NOM-138- SEMARNAT/SSA1-2012, establishes a maximum allowed limit of 4,400 ppm gasoline in soil. Therefore, the objectives of this research were i) biological recovery of the soil impacted by 30,000 ppm of gasoline, by biostimulation with commercial detergent 123® plus a mineral …
