Benzene is to be absorbed from coal gas by means of a wash oil. The inlet gas contains 3% by volume of benzene, and the exit gas should not contain more than 0.02% benzene by volume. The suggested oil circulation rate is 5 kg oil per 1m3 of inlet gas measured at STP. The wash oil enters the tower solute free and the operation is carried out at atmospheric pressure.
The RMM for benzene is 78 and the equilibrium data are:
Benzene in oil (% by wt)
0.05 0.01 0.5 1.0 2.0 2.5 3.0
Equilibrium partial pressure of benzene in gas (mbar)
0.15 0.31 2.0 5.3 13.3 21.4 33.4
The plate OAB forms an equilateral triangle which rotates counterclockwise with increasing speed about point O. If the normal and tangential components of acceleration of the centroid C
A cross section of a cottage, 20 ft wide, is an isosceles triangle. If the slope of a side is 1.75 and there is a second floor 8 ft above the ground floor, what isthe width of the second floor?
Three streams of polluted air are combined prior to treatment in an electrostatic precipitator (ESP). The flow and particulate concentration of each stream are 600 cfm at150 mg/m^3, 700 cfm at 200 mg/m^3, and 500 cfm at 1000 mg/m^3.
Assuming the lagoons are well mixed and that there are no losses or gains of water in the lagoon other than the sewage input, what biodegradation reaction rate coefficient (in day^-1) must be achieved for a first order reaction that governs the de..
A pig farmer owns a 20-arce farm and started business with 22.1 pigs. After one year, he has 319 pigs. Assuming a constant growth rate, what is the doubling time in units of days.
Carbon disulfide (CS2) reacts with excess chlorine (Cl2) to produce carbon tetrachloride (CCl4) and disulfur dichloride (S2Cl2). If 69.7 g of CS2 yields 62.6 g of CCl4, what is the percent yield? (Hint, you must first write the balanced equation.)
A water treatment llant and the water treatment plant removes calcium hardness (Ca2+) by precipitating (making) CaCO3(s). If, after establishing equilibrium with CaCO3(s), the dissolved Ca2+ concentration is 10 mg/L and the pH is 10.5.
If the temperature of rod CF is increased by 10 degrees C and that of rod BC is decreassed by 40 degrees C, determine the normal stress in rod AD. The rods are two meters long.
Using darcy-weisbach equation, calculate the major friction head loss for a 24 inch diameter, 120 ft long pipe that can carry water with a flow rate of 5 cfs. Assume the temperature of water is 70 deg F and the roughness of the pipe is 0.0016 ft.
a tape is calibrated and found to measure 100.04ft between the 0- and 100-ft marks. what measurements should be laid out to establish a horizontal distance of 682.25ft?
we have the I-section made of steel (E = 29,000 ksi) which is to be used as a column, pinned at the top, and fixed at the base. Bracing is to be added in the direction of the weak buckling axis, at an unknown height, H.
A rear-wheel-drive 3000lb drag race car has a 200-inch wheel base and a center of gravity 20 inches above the pavement and 140 inches behind the front axle. The owners wish to achieve an initial acceleration from rest of 15 ft/s on a level paved s..
