b$.$ List the optional information that could be included on a process flow$-$sheet.

c$.$ Dimethyl Ether $($DME$)$ is a proposed alternative to diesel fuel that is being looked into by car and truck manufacturers worldwide. Conventionally, DME is produced by feeding Methanol into a fixed$-$bed gas$-$phase reactor over a y$-$alumina catalyst $(2C{H}_{3}OHC{H}_{3}OC{H}_3+H_{2}O).$ Using this process and normal operating conditions and up $($:$\frac{20}{b}ar\}$ operations can reach $80\%$ Methanol conversion. The proposed process utilizes the innovative catalytic distillation technology using Amberlyst $35$ catalyst to achieve a $99\mathrm{.}8\%$ Methanol conversion. The catalytic distillation is executed at $-130C,$ and produces water as a byproduct, which exits as the bottoms stream. In order to create

a process that is environmentally sustainable, the small amounts of Methanol and DME in the bottoms stream are removed ueing bioreactor and the water is then released into a nearby river. The product DME is mixed with mineral oil to meet Iso standards and is then stored in an on$-$site spherical tank.
