Cunene is made by alkylation of benzene with propylene over zeolite catalyst. To maximize selectivity to desired products, several beds of catalyst are used inside the same reactor. A mixture of feed and recycle benzene enters the top of the reactor and the feed propylene is split so that a portion of the propylene is fed to each catalyst bed. A large excess of benzene is used, to minimize propylene oligomerization and ensure complete reaction of propylene. The reactor product is cooled and sent to a stabilizer column that removes any light hydrocarbons. The bottom from this column is sent to a benzene column that recovers benzene overhead for recycle to the alkylation and trans alkylation reactors. The bottoms from the benzene column are distilled to give commence product and a heavy stream. The heavy stream is further distilled in a heavies column to give a mixture of dipropyl- and tripropyl-benzene overhead and a heavy waste stream as bottoms. The distillate from the heavies column is sent to a trans alkylation reactor and reacted with excess benzene. The product from the trans alkylation reactor is returned to the benzene column. Sketch a block flow diagram of the process.

A beaker filled with an equimolar liquid mixture of ethyl alcohol and ethyl acetate evaporates at O°C into still air at 101 kPa (1 atm) total pressure. Assuming Raoult's law applies, what will be the composition of the liquid remaining when half t..
A stream of 5.00 wt% oleic acid in cottonseed oil enters an extraction unit at a rate of 100.0 kg/hr. A separate stream of propane enters the unit. Propane is able to dissolve oleic acid but cannot mix with the cottonseed oil. Two streams exit the un..
The effect of a hazardous substance depends on the concentration of the substance that is present in the body's systems. The concentration depends on the stages of toxicokinetics What are the four main stages of toxicokinetics
Plain carbon steel would be a suitable material for the tanks, but it is essential that the polymer does not become contaminated with iron in storage. Suggest some alternative materials of construction for the tanks.
Carbon dioxide can be separated from other gases by preferential absorption into an amine solution. The carbon dioxide can be recovered by heating at atmospheric pressure. Suppose pure CO2 vapor is available from such a process at 80°C and 1 bar. Sup..
