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.

HEAT TRANSFER - EXAMPLE 5.3 : In a cylinder with a hollow, let a is outside radius and b is the inside radius. In a steady state temperature distribution with no heat generation, the differential equation is (d / dr) (r dT / dr) = 0 where r is for radius and T is for temperature. (a) Integrate the heat equation above into T(r) in term of r. (b) At r = a, T = c; at r = b, T = d. Find the heat equation of T(r) in term of r, a, b, c, d.

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.35 : A voluntary accountant is performing Du Pont Analysis for a charitable engineering organization. References for 3-step Du Pont formula are : (ROE) = (Net Income $) / (Equity $), where ROE is Return On Equity. (ROS) = (Net Income $) / (Sales $), where ROS is Return On Sales. (Asset Turnover) = (Sales $) / (Assets $). (Leverage) = (Assets $) / (Equity $). From the balance sheet and income statement, the company has Assets of $3753.19 this year and $3216.86 last year. Sales for this year is $2292.34. Let ROE = 0.37 and ROS = 0.21. (a) Calculate the Asset Turnover of the organization. (b) Find the value of the organizational Leverage. (c) Calculate the Net Income $ of the organization.

DIFFERENTIAL EQUATIONS - EXAMPLE 20.2 : During the landing process of an airplane, the velocity is constant at v. (a) If the displacement of the plane is x at time t, find the differential equation that relates t, x and v. (b) The plane has 2 parts of wheels - the front and the back, separated by a distance L. The front part of the wheel touches the land first, that allows the straight body of the plane to form an angle T with the horizontal land. If the vertical distance between the back part of the wheel and the horizontal land is y, find the equation of y as a function of L and T. (c) Find the differential equation that relates dy as a function of dt, v and sin T. (d) Find the differential equation that consist of dy as a function of y, L, v and dt. (e) Find the equation of y as a function of v, L, t and C where C is a constant. (f) When t = 0, prove that y = exp C as the initial value of y.
