Problem
1) A fractional factorial design has been used to study on the effect of 3 parameters including adsorbent
concentration (300 and 500 ppm), pH value (4 and 10) and reaction time (6 and 12 hours) on the
adsorption capacity of a composite for removing of methylene blue from a wastewater. If the results
obtained for two repetitions of the tests are according to the following table, it is desirable:

With 100,000 BPD of the following crude (API = 36), estimate the products of the atmospheric distillation column. If the atmospheric residue of the crude is taken at 650+ F. It enters in a vacuum distilla- tion tower to give three products: light vacuum gas oil (650-850 °F), heavy vacuum gas oil (850-1050 °F) and vacuum residue (1050+ °F). Calculate the mass flow rate of these products. Then calculate the sulphur content (lb/hr) for each product.
