Question
Phthalic anhydride (PA) is produced by the oxidation of o-xylene (C8H10) in a fixed bed reactor at 350pC according to the following reaction:
C8H10 + O2 C8H4O3 + H2O
A condenser is used to remove all the PA (C8H4O3) as a mixture of solid and liquid. How many kilograms of o-xylene are recycled per hour if the purge gas is 78% N2 (the balance is a mixture of xylene, air, and H2O) and 60% conversion of o-xylene takes place on one-pass through the reactor?

- Q5 Pure sulphur is burnt in a sulphur burner with dry air. Oxygen is used 20% excess above that required for the complete combustion of sulphur to SO3. The efficiency of burner is such that only 30% of the sulphur burns to SO3 ,and remainder goes to SO2 .Calculate : (a) the analysis of the resulting mixture in mole % and (b) the weight of gas per kg of sulphur burnt.arrow_forwardProblem #3 (35%) Vinyl chloride is synthesized through the following reaction of acetylene and hydrochloric acid: C2 H2+ HCl → CH2CHC The following undesired reaction also occurs simultaneously, producing dichlorethane instead: C2 H2 + 2HCI C2 H4CL2 - These reactions occur in a reactor during the manufacture of vinyl chloride. In this process, the feed to the reactor contains 100 Kmol/h of acetylene. The same feed also contains HCI, 16% in excess of that needed if the desired reaction went to completion, as well as 1.2 Kmol/h of an inert contaminant (water vapor). The single-pass fractional conversion of acetylene in the reactor is 12%, and 94% of the C2H2 so reacted is consumed in the first reaction to form vinyl chloride. The only stream leaving the reactor goes to a separation unit where all the vinyl chloride and all the dichlorethane are condensed and removed through a bottom liquid stream. This liquid stream contains nothing else.

- Alumina from bauxite separation stage calculations A crucial step in the production of aluminum from bauxite ore is the separation of alumina from the remaining mineral impurities in the ore. In the Bayer process this is accomplished by treating bauxite with aqueous NaOH to produce NaAIO2 (alumina). NaOH(aq) + Al(OH)3(s) → NaAIO2(aq) + 2H2O(1) Since NaAIO2 is water soluble while the residual mineral constituents of bauxite are not, a separation can be achieved by allowing the minerals to settle out and decanting the aqueous solution of NAAIO2 and unreacted NaOH. In order to further recover any NAAIO2 entrained in the settled mineral solids, this "mud" is repeatedly washed with water and allowed to settle, and the wash water is decanted. The figure below shows one stage of this washing-settling process.
