Arverobic ianahis produce harmful gases which primarly contain methane and carbon dioxide. Table 1 ahows a range of volume fractions of the other varicus companents of anaerotic: langtal gas (t.FG). Lanafit gases are produced when bacteria break down organic waste. The amount of these gases depends on the type of waste present in the tandnil, the age of the landral, coxgen content, the arnourt of moisture, and terngerafure. Table 1: Typicel anovrobic LFG composnion The proposted absorption treatrnent is shown in Fig. 1. The feed consists of 50 moles of CH4 and 50 mol?s of CO2. It is desired to reduce the CO2 concentration by scrubbing with pure water in the gas absorption system. The total feed gas flow rate enters the absorption column at 3000kgh. The mass transter coefticiont of CO4 in water and henry/s gas constant value are given in Table 1. Stubants in goup of maxmum fout (4) manbers are requered to design teancih siuing of gas absorption column that sut the sdoressed wcenano using the ponepal concepts of absorption.
