You should use a 10-year plant lifetime and an interest rate of 15%. In the design of a chemical process the need is the public need for the product, the commercial opportunity as foreseen by the sales and marketing organization. With the advent of computers and simulating software like ASPEN PLUS® it is possible to design and optimize a particular process. Future Work Three months to develop detailed design items Six months for constructing and operating the pilot plant Two years for full plant construction Plant is scheduled to operate for a minimum of twenty years Profitability is reached at the end of two years of operation Fuel. These economic details were introduced in ChE 38, and will be covered in more detail in ChE 182/183. Cumene production process is gaining importance and so the process needs to be studied and better ideas suggested such that the production cost is reduced. The plant is designed to have a capacity of 595 million lb/yr (270,000 t/yr) of cumene at a 0.9 stream factor. the revamp of the existing cumene plant for a total of 400 kt/y cumene capacity at Versalis Porto Torres site. The process described by Peterson and Schmidt (2002) is taken as base for simulating the system. Air may be eventually washed to mainly neutralize SO2 traces coming out of the Sulfuric Acid Plant stack. Since the second has a higher activation energy than the first, low reactor temperatures improve selectivity of cumene. Production 1. This Aspen Plus model simulates the production of cumene by the alkylation of Benzene using Propylene and Zeolite catalyst. C. Modification and addition to existing plant. For 300 tons per day cumene production outline of the process which uses a solid phosphoric acid as catalyst. The aim of this report is to design a plant that produce 175,000 tons/year of isopropylbenzene (cumene) with a purity of 99.4% using the Honeywell UOP QMax technology. The above equation for estimating the cost of cumene is based on the minimum price that cumene could be sold for to cover our operating expenses. Design Report for Cumene Production. The process description of Turton et al. The reactor design involves design of equilibrium based reactor as well as kinetic based reactor. The major parts of a cumene production plant are reactor system, separation system and they are optimized. This design would overall benefit the cumene plant in a cost effective way. Cumene Production Reaction B. DESIGN: PROCEDURE, RESULT & DISCUSSION. (1) As a Balance between HP Steam Import and LP Steam Export. However, low reactor temperatures … (2003) provides The chemistry of the cumene process features the desired reaction of benzene with propylene to form cumene and the undesirable reaction of cumene with propylene to form p-diisopropylbenzene. This makes a difference in maintenance of the entire system, particularly during shut down for maintenance. OXIDATION / CONCENTRATION The raw material for this section is Cumene which is oxidized using compressed air. By turning the job of two towers into a single column reduces the amount of equipment needed for the plant. This chapter is divided into two main parts as (i) Reactor and (ii) Separator. CHAPTER 3. In 2015 a further 450 kt/y cumene capacity plant has come on stream in China, currently under revamping to 600 kt/y. New production capacity to meet growing sales. Cumene process reaction is exothermic in nature so a complex shell and tube reactor designs are not sufficient for energy conversion, tremendous research work is involved in design a rector of Cumene production from benzene and propane. Cumene is previously washed with a caustic solution to remove impurities that can affect the oxidation. (II) Setting The Design Basis (Data Collection) The system considered for study, simulation and optimization is a cumene production plant. Design Report for the Production of Cumene Submitted to: Dr John Schlup , economic feasibility of developing a new cumene production process an existing plant site for , The project will be built over 2 years and have a project life of 15 years A 4..
