Look at today's paradox... A medical student after studying at large become doctor, law student normally a lawyer, Chartered accountant is having profession as same, and so is the case with othe professionals... But Engineers in most of the cases, do MBA and technically opt for a sales, marketing, higher mgmt, management consultant and what not but they detatch themselves from Engineering... Still what the world is now, what we see as a symbol of development in any sphere is just because of Engineers and if u ask anyone, what would you say about them... Then there doesn't seem to be any accurate formal word of praise for them... Ask about Doctors, "they are life savers" ask about teachers, "they show us the right path", ask about the lawyer, they help in bringing justice... Fine... But ask about engineers... Silence! This is unfair... Instead of celebrating Happy Birthday of Vishveshvaraiya as Engineers Day, a true respect to them will be to acknowledge and appreciate their contribution to this world...
Comparison of Water Scrubbing , Bio-scrubbing , Ferrosorp , Chemical Scrubbing , and Iron Wool for H₂S removal from raw biogas : 1. Principle Parameter Water Scrubbing Bio-scrubbing Ferrosorp Chemical Scrubbing Iron Wool Mechanism Physical absorption of H₂S in water Biological oxidation of H₂S to elemental sulphur Adsorption of H₂S on iron oxide-based media Chemical reaction with scrubbing solution Reaction of H₂S with iron to form FeS 2. Efficiency Parameter Water Scrubbing Bio-scrubbing Ferrosorp Chemical Scrubbing Iron Wool H₂S Removal Efficiency 90-99% (depends on water solubility and pressure) 95-99% (depends on bacterial activity) 90-99% (depends on sorbent capacity) 99 5-99 9% (very high for low ...
