Introduction

It is one of the most important steps while designing a plant to design pipes and compressors. The piping design include the suitable size, construction material which is crucial in minimizing the maintenance cost in the industry. Due to any outflow in the process or anything that could affect the economy of the plant or the product quality, this design was performed.

A full classification of each stream in the process will be provided in this section. Based on the classified conditions of the streams, all the design parameters will be calculated along with best material of construction. Moreover, calculation for the used compressors will be elaborated in this section.

Pipes objective in the plant is to work as a transportation medium for the reactants and the products. In addition, they occupy a massive area of the plant and therefore their design should follow the highest standards and guarantee the best quality with the least possible cost.

During the design of piping, there are several aspects and consideration should be taken in account. These aspects include pressure drop inside the pipes, material used in pipes construction, pipes sizing and finally the interior classification of the pipe walls. Utilizing the previous chapter (Simulation), the data in this section was obtained.

Titration was applied to evaluate the diameter of the pipes in order to meet the regulation. The pressure drop is evaluated at psi/100 ft, since the length of the pipes is not provided. Furthermore, calculation and design of all pipes and compressors in this section follow the heuristics obtained from “Analysis, Synthesis and Design of Chemical Process” textbook. Finally, the members of the group envisage the layout of the plant, and it will be elaborated in the section of layout.

The regulations that are illustrated by a special and official organization are known as standards. These standards help in the construction of industrial plants at high level of safety. The following standards were collected from various organizations in piping design section:
