Chapter 4, Problem 4.80P
Methanol is synthesized from carbon monoxide and hydrogen in a catalytic reactor. The fresh feed to the process contains 32.0 mole% CO. 64.0% H?, and 4.0% N>. This stream is mixed with a recycle stream in a ratio 5 mol recycle/1 mol fresh feed to produce the feed to the reactor, which contains 13.0mole% N2. A low single-pass conversion is attained in the reactor. The reactor effluent goes to a condenser from which two streams emerge: a liquid product stream containing essentially all the methanol formed in the reactor, and a gas stream containing all the CO, H2, and N2 leaving the reactor. The gas stream is split into two fractions: one is removed from the process as a purge stream, and the other is the recycle stream that combines with the fresh feed to the reactor.
- Assume a methanol production rate of 100 kmol/h. Perform the DOF for the overall system and all subsystems to prove that there is insufficient information to solve for all unknowns.
- Briefly explain in your own words the reasons for including (1) the recycle stream and (ti) the purge stream in the process design.

Naturally occurring barium sulphate is converted into water–soluble formby heating with carbon, thus reducing the sulphate to barium sulphide(BaS). The resulting reaction mixture, “barium black ash”, contains 65%w/w soluble BaS and is to be leached with water. Black ash is to be fedto a tube mill at 100 tonnes per day, together with the overflow from thesecond of a cascade of thickeners, and the effluent from the mill is fed tothe first thickener. All the barium is dissolved in the mill. The strongsolution leaving the first thickener contains 20% w/w BaS by weight.Each thickener delivers a sludge with 1.5 kg liquid per kg of insolublesolid. Both liquids leaving each thickener are to have the same BaSconcentration. BaS lost with the final sludge should not exceed 1 kg perday.How many thickeners are needed?
A steady-state process to recover crystalline potassium chromate (K,CrOz) from an aqueous solution of this salt
is required. Four thousand kilograms per hour of a solution that is one-third K,CrO, by mass is joined by a recycle
stream containing 36.4% K2CrO7, and the combined stream is fed into an evaporator. The concentrated stream
leaving the evaporator contains 49.4% K,CrO; this stream is fed into a crystallizer in which it is cooled (causing
crystals of K,CrO, to come out of solution) and then filtered. The filter cake consists of K,CrO, crystals and a
solution that contains 36.4% K,CrO, by mass; the crystals account for 95% of the total mass of the filter cake. The
solution that passes through the filter, also 36.4% K,CrO,, is the recycle stream.
1- Draw the flowchart of the system and put all known information.
2- Calculate the rate of evaporation, the rate of production of crystalline K,CrO7, the feed rates that the
evaporator and the crystallizer must be designed to handle, and…
