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.

INTRODUCTION
1.1 BACKGROUND OF STUDY
Design is the creation of plan or convention for the construction of an object or equipment to solve the human process. It is the process through which the process Engineers or designers generates new ideas, and technology that is capable of solving the societal problem. It is synthesis, the putting together of ideas to achieve the desired goal/objective.
Design is mainly applied for two primary purpose viz personnel expression and product or process development. The personnel expression is the type of design associated with art, it is divided into concrete and abstract design and it is often a source of beauty and interest. The design for product or process development is when a design serves some useful purpose, such as the shape of a new product or automobile wheel. Design for product or process development involves Aesthetic design, functional design etc.
