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

A concentric, counter-current heat exchanger is used to cool lubricating oil. Water is used as the coolant. The mass flow rate of oil into the heat exchanger is 0.1 kg / s = FO. For oil, the inlet temperature TIO = 100 degree Celsius and the outlet temperature TOO = 55 degree Celsius. For water, the inlet temperature TIW = 35 degree Celsius and the outlet temperature TOW = 42 degree Celsius. What is the mass flow rate of water in kg / s, FW needed to maintain these operating conditions? Constant for heat capacity of oil is CO = 2131 J /(kg K) and for water is CW = 4178 J /(kg K). Use the equation (FO)(CO)(TIO – TOO) = (FW)(CW)(TOW – TIW).

A distillation column separates 10000 kg / hr of a mixture containing equal mass of benzene and toluene. The product D recovered from the condenser at the top of the column contains 95 % benzene, and the bottom W from the column contains 96 % toluene. The vapor V entering the condenser from the top of the column is 8000 kg / hr. A portion of the product from the condenser is returned to the column as reflux R, and the rest is withdrawn as the final product D. Assume that V, R, and D are identical in composition since V is condensed completely. Find the ratio of the amount refluxed R to the product withdrawn D. Hint : Solve the simultaneous equations as follow in order to find the answer (R / D) : 10000 = D + W; 10000 (0.5) = D (0.95) + W (0.04); 8000 = R + D.

ENGINEERING NUMERICAL METHODS - EXAMPLE 19.2 : For a mixture of benzene (B), toluene (T) and xylene (X), the equation applies where x for B, T and X will sum up to 1. The equation of x for each component is x = (L / V + 1) (F) / (L / V + K). The data of F for each component are : 0.5 for B, 0.35 for T, 0.15 for X. The data of K for each component are : 1.98 for B, 0.76 for T, 0.24 for X. When x for B + x for T + x for X = 1, find the values of (a) L / V; (b) x for each component of B, T, X respectively. You may use Excel program - Data : What-If-Analysis for Goal Seek to perform the iterative calculations.
