Answer / verma d k

absorber a process equipment are used to remove one or
more gaseous component from gaseous mixture by using
suitable type solvent mostly present in lessr quantity.
Scrubber are basically pollution control equipment used to
scrub out air pollutant ( mainly particultes, and acid
gases) from exhaust system.
Mechanism of Scrubber: inetial impaction or diffusion
method mostly and lesser use of chemical affinity.
Mechanism of absorber: Chemical affinity

Answer / pafl

Absorber is used mostly for removal of only gaseous component from gaseous stream using suitable solvent which then is regenerated while scrubber is used to remove pollutant from outgoing gases mostly pollutants are gases (acid gases), particulate, dust etc. while there is no necessary regeneration of solvent in scrubber other assembly is similar in both absorber and scubber

Answer / khaja moizuddin

Scrubber neutralize the ph of the evolved gaseous mixture where absorber dont

Answer / nag

absorber: which seperates the particles based on the
affinity between particles and stationary absorbent.
scrubber: which seperates the heavier particles based on
the velocity principle. when ever heavy particles collides
with scrubber inclined surface, velocity will become zero.

Question 56 - The kinetic behavior of an enzyme could be described using Michalis - Menten equation : Vo = Vmax [S] / (Km + [S]). Derive this equation from [ES] = [E]total [S] / (Km + [S]), Vmax = Kcat [E]total, Vo = Kcat [ES].

We are having proplem with the persperation smell in ETT/ECHO room in our cardiac hospital.The 2 Ton of AC is not conditioning the environment. We have to use exhaust fan to through out of the room bad air. Could anyone suggest how to coup with this effectively using chemical engineering. Any permanent solution to neutralise the bad smell.The Air freshners are not doing enough instead making a bad odour.

POLYMER ENGINEERING - QUESTION 24.1 : The molecular weights M in kg / mol of 3 different monomers a, b and c in a polymer are Ma = 14, Mb = 16 and Mc = 18. The fraction of polymer chain X of 3 different monomers a, b and c in a polymer are Xa = 0.5, Xb = 0.3 and Xc = 0.2. (i) Calculate number average molecular weight by using the formula Ma Xa + Mb Xb + Mc Xc. (ii) Calculate weight average molecular weight by using the formula (Ma Xa Ma + Mb Xb Mb + Mc Xc Mc) / (Ma Xa + Mb Xb + Mc Xc). (iii) Calculate the polydispersity by using the answer in (ii) divided by answer in (i). (iv) If the molecular weight of repeat unit is 12, calculate the degree of polymerization by using the formula (Ma Xa + Mb Xb + Mc Xc) / (molecular weight of repeat unit).
