Answer / raj kumar

mixd bed has the mixture of resin as strong base anion and
strong acid cation. so due to presence of acid cation ph is
reduced

Answer / amrut maisuria

why water passes first in SAC and then SBA ?

Answer / a n jha

it seems ratio of cation and anion resin quantity are not in
balance.if the cation resin is more than anion resin,ph of
dm water shall go less than 7 i.e. it will be acidic in nature.

Answer / nitesh raghuwanshi

When water passed from SBA AND COMES IN MB , MB CATCH SOME MORE ION THAT WHY WE GET LESS PH & LESS CONDUCTIVITY , LESS SILICA Water . Another reason in MB IN TOP ANION RISEN IN BOTTAM CATION RISEN SO WHEN WATER COMS IN MB FIRST ITS ALKALI BECAUSE OF ANION RISEN AFTER ITS ACIDIC FOR CATION RISEN.

Answer / shaik.subhani

dm plant heart of the mb this meaning mixed bed first of all
sac out let water is coming now mbvessul top side anion
reesin bottom side cation resin water is comming anion that
is the high ph water converted to low ph

Answer / alok behera

In Mb, cation resin release H+ ion, and Anion resin released OH ion. That means H+ and OH- ion. So that is pure water. Normally pure water ph is 6.2 to 7.5. So mixed bed ph decrese.

Answer / amit katiyar

Mixed bed is used only for polishing of impurities which is remain or slippagefrom SBA like sio2 sodium act due to it lower size and shape. mixed bed contains both resin cation and anion so here remained inpurities are exchanged and pure water gained that means lower in ph conductivity and silica act.

Answer / adas

Due dissolve carbon dioxide the PH is acidic

Question 32 – Let 1 ^ 1 = 1, 2 ^ 2 = 4, 3 ^ 3 = 27. By using the Excel computer programming – either by Solver or Goal Seek, find the value of v for the Van der Waals equation (P – a / v ^2) (v - b) = RT where a = 18.82, b = 0.1193, P = 2, R = 0.082, T = 5000 for benzene. Describe briefly how to use Solver and Goal Seek in Excel program of computer to find the solution quickly.

THERMODYNAMIC - EXAMPLE 10.1 : The water is superheated steam at 440 degree Celsius and 17.32 megapascals. Estimate the enthalpy of the steam above. From the steam table for water at 440 degree Celsius, enthalpy of steam, h at 18 megapascals is 3103.7 kilojoules per kilogram and at 16 megapascal is 3062.8 kilojoules per kilogram. Assume that h = mP + c where P is pressure; m and c are constants at fixed temperature with small differences in P.

Question 82 - (a) The Hyperion sewage plant in Los Angeles burns 8 million cubic feet of natural gas per day to generate power in United States of America. If 1 metre = 3.28084 feet, then how many cubic metres of such gas is burnt per hour? (b) A reservoir of natural gas produces 50 mole % methane and 50 mole % ethane. At zero degree Celsius and one atmosphere, the density of methane gas is 0.716 g / L and the density of ethane gas is 1.3562 mg / (cubic cm). The molar mass of methane is 16.04 g / mol and molar mass of ethane is 30.07 g / mol. (i) Find the mass % of methane and ethane in the natural gas. (ii) Find the average density of the natural gas mixture in the reservoir at zero degree Celsius and one atmosphere, by assuming that the gases are ideal where final volume of the gas mixture is the sum of volume of the individual gases at constant temperature and pressure. (iii) Find the average density of the natural gas mixture in the reservoir at zero degree Celsius and one atmosphere, by assuming that the final mass of the gas mixture is the sum of mass of the individual gases. Assume the gases are ideal where mole % = volume % at constant pressure and temperature.

Question 49 - According to rules of thumb in chemical process design, consider the use of an expander for reducing the pressure of a gas when more than 20 horsepowers can be recovered. The theoretical adiabatic horsepower (THp) for expanding a gas could be estimated from the equation : THp = Q [ Ti / (8130a) ] [ 1 - (Po / Pi) ^ a ] where 3 ^ 3 is 3 power 3 or 27, Q is volumetric flowrate in standard cubic feet per minute, Ti is inlet temperature in degree Rankine, a = (k - 1) / k where k = Cp / Cv, Po and Pi are reference and systemic pressures respectively. (a) Assume Cp / Cv = 1.4, Po = 14.7 psia, (temperature in degree Rankine) = [ (temperature in degree Celsius) + 273.15 ] (9 / 5), nitrogen gas at Pi = 90 psia and 25 degree Celsius flowing at Q = 230 standard cubic feet per minute is to be vented to the atmosphere. According to rules of thumb, should an expander or a valve be used? (b) Find the outlet temperature To by using the equation To = Ti (Po / Pi) ^ a.
