“…Acetone is a petrochemical feedstock needed in high demand globally, and because many production routes follow a cumene path, which is an expensive, toxic, and non-economical path, this work considers the IPA route, and cheap, available raw materials are closer to the location of the plant (Eleme, adjacent to petrochemical plant) [19].…”

A design of 225[metric tons per year] of an acetone plant from isopropanol alcohol (IPA) was developed. The design considers the fundamental principles of mass and energy balance to size the units of the acetone plant, particularly the Gibbs reactor, separator, absorber, and distillation columns. The beauty of plant design is to account for the material and energy conservation principles interactions and specify the dimensions of the main unit operations of the plant. The HYSYS simulation software was used to design the acetone plant, and the properties of the fluid were used to manually size the plant. The four components resulting from the reaction of IPA and water (acting as a catalyst) to obtain acetone and hydrogen are 2-propanol, acetone, hydrogen, and water. The balance of how these components is heated, reacted, cooled, separated, absorbed, and distilled of acetone from a mixture of IPA/water is shown logically with sketches for the material and energy values of the key unit operations of the plant. The mechanical design of the units was performed to determine the thickness of the columns. In addition, a cost-plus-economic analysis of acetone was carried out. The results indicate that, the sizing of the units gave the following results viz: manually, the reactor with sized 5.4 [m3], 1.56[m] and 2.34[m] as the diameter and height respectively, the separator was sized to 1.78[m] diameter and 2.67[m] height with 6.631[m3] volume, the absorber column gave 0.085[m] diameter, 1.1[m] height, and the distillation column design values are 0.202[m] column diameter, 10.8[m] height and the weir length of 0.154[m]. The overall cost, including the cost of utilities for the entire plant, was [$]7.792million; the equivalent annual operating cost was [$]4.408million; and the thicknesses of the reactor, separator, absorber, and dilation columns are respectively 2.42[mm], 11.71[mm], 1.99[mm] and 3.36[mm]. Validation of the manual design was carried out with HYSYS simulation results, which indicated that the design models were reliable and could be adopted for the design because the deviation values on the specifications of the units are small ranges from 0.04 – 0.4. The result of the design showed that acetone production from the IPA route was recommended and that the HYSYS simulation formed part of the entire design of the acetone plant.

Cumene production generally involves irreversible and exothermic reactions that leads to an increase in product temperature and needs to be cooled for further processes. The high temperature of reactor product can be utilized as a heat transfer fluid in heat exchanger. This modification process is essential for improving energy efficiency by recycling the reactor output with high temperature as a heat transfer fluid, so that the implementation of replacing the heater with a heat exchanger can be carried out for the process of increasing the initial feed temperature. In an effort to enhance energy efficiency in the cumene production process, simulations were conducted using HYSYS and the comparison of energy efficiency for both basic and modified processes can be evidenced by comparing the total amount of energy required during the process. The results shows that the total amount of energy required for the modified process is 39,814,003.7 kJ/h, while for the basic process is 40,588,937.4 kJ/h, with a difference of 774,933.7299 kJ/h. Since the total amount of energy required in the modified process is smaller than the basic process, then the modification process will increase the energy efficiency of cumene production.
