AID-P System

About Solution

">AID-P is seemed to be splendid route to treatour major challenge – climate changes
the produced air components aretotally in the optimal ranges supposed to be found in the breathable air thatits ranges are shown in based on WHO database. Inthe third stage, many materials could be used as electrodes like iron,however, we used graphite because of its high efficiency in conductingelectric current. Also, results show that the system’s cost is far less thanother systems’. Accordingly, Aid System with the recent and planedmodifications can be the ideal solution for air pollution.AID-P System is made up within 4 stages, and 2 sub-stages.The whole project is acting in some kinds of reactions thatdecisively lead to obtain the required project to treat thegreenhouse gasses.The first sub-system “air suction system”: simply, it is an airsucker or a blower. The rest of the sub-systems depend on thevelocity of the air that system provides it.The second sub-system “electromagnetic generation”-supported by physics topics-: that part of Aid-P Systemcharacterizes it from the prior projects as it can provide the needof electricity in the first and third stages. That sub-system iscomposed of a generator with blades in its arm’s terminal suspended in the first container. Itconverts the mechanical energy of the air to electrical energy.The first stage
dust static electrification – as a considerable amount ofdust produced in industry, this stage works to handle that. This stagecontains a glass container, two electrodes, some wires, and power source;both electrodes are connected to the negative side of the power supply.When dust particles enter the first container with the velocity of the air, apolarization process takes place upon them making them attract to theelectrodes making the air lack of dust.The second stage “CO2 removal”: As mentioned, CO2 is the essential aspect of all industries’exhaust, so this stage was combined. The stage enclose a stainless steel (316) container filledpartially with sodium hydroxide in its aqueous state (NaOH). NaOH absorbs CO2 from thepassing air producing sodium carbonate and water via the coming equation:CO2 (g) + 2 NaOH (aq.) ------ Na2CO3 (aq.) + H2O (l) enthalpy = -169.80 KJ. equ (1)Every 80 grams of NaOH reacts with 44 grams of CO2 forming106 grams Na2CO3. The by-product of that reaction (Na2CO3)has high economic value as it is considered as a main rawmaterial for food industries. CO2 is removed from the air withrate equals the half of the rate at which NaOH is consumedgraph (3).The third stage “viruses disinfection”: Industrialexhausts could be saturated with viruses and otherpathogeneses which are perilous to the living organismsfigure (4). This stage have been toted to the system.Two graphite electrodes connected to electric sourceare submerged in a container filled partially with HCl.Electrolysis process ensue producing H2 gas in theanodic side and Cl2 gas in the cathodic side accordingto the following equations:2H+ + 2e
------- H 2 (g) (anodic reaction)2Cl
----- Cl 2 (g) + 2e
(cathodic reaction)Chlorine works as a disinfection agent, which killspathogeneses freeing air from their risks.The fourth stage “toxicity removal”: Although Cl2 has an important rolein disinfecting air, it is one of the most lethal gases. That final stagereabsorbs chlorine after the disinfection process via a chemical reactionwith NaOH producing table salt and hypochlorous acid:Cl2 (g) + NaOH (aq.) ----- NaCl (aq.) + HClO (aq.)enthalpy = -100.11 KJ.
