Design Of Molten Salt Cooler In Process Plant For Production Of 2-7 X 104 Tonnes/yr Of Phthalic Anhydride By Diret

ABSTRACT

The general approach to any design of a process plant involve an advanced network of Chemical Engineering processes.  This equipment design project was carried out to design a molten salt cooler (heat exchanger) for production of 2.7 x 104 tonnes/year capacity of phthalic anhydride by direct synthesis of gaseous naphthalene.

The information concerning the design of this equipment was gotten from literature review which was then used to obtain the physical properties datas.  The material and energy balance calculations were also performed and reviewed as shown in appendix A, B, C and D.

Appropriate sizing of the equipment (cooler) was also done using the physical properties data and proper instrumentation and control analysis was also done.

The cost evaluation of the cooler was also done to determine the present cost of the equipment.  The cost of estimation was performed to ascertain the economic viability of the equipment.

At the end a good proper design work was achieved.
