session I

$S1(40p)$ According to the reaction given below, product $D$ is produced in a chemical process. The flow diagram is below

there is no $B$ in the reactor output current in the given process.

$A+B=C+D$

The fixed capital investment of the process is at the end of the first year and $510$$ at the end of the second

After commissioning $(2.$ at the end of the year$)$ the sources and amounts of cash flows are shown in the following chart

is given. The life of the process after commissioning is $10$ years. There is no waste processing cost.

As a result of the research, using an additional distillation column, $99\%$ of product $C$ instead of $92\mathrm{.}5\%$ it has been

calculated that it can be produced in purity. In this way, service costs increased by $15\%,$ while sales revenues also increased by

it is expected to increase by $30\%.$ There is no change in labor costs. Adding

the diameter of the distillation column considered is $2\mathrm{.}5m$ and the height is $25m.$ There are $25$ trays available in the

column and $15$ in the barg it is operated. The columns and trays are made of stainless steel material. The total of

columns and trays its cost accounts for $60\%$ of the total module cost of the new distillation system. New $($modified

calculate the non$-$amortized production cost of the process. $(CEPCl2018=616\mathrm{.}0$;CEPCl$2001=397\mathrm{.}0).$
