Cumene in the global petrochemical industry is used primarily as a reactant for production of phenol. Phenol and Cumene Process Summary PEP Review 2013-11. About This Process Essentially all cumene produced worldwide is used as a feedstock in phenol plants, which convert it to phenol and acetone by cumene peroxidation. Benzene and propylene are reacted to form cumene and cumene hydroperoxide in the Cumene Process. Cumene in presence of sodium carbonate is oxidised by passing air or oxygen. Phenol : 40,000 TPA; Acetone :24,640 TPA; The CUMOX unit has been divided into the following process section. A route analogous to the cumene process begins with cyclohexylbenzene. The facility consists of a Cumene Process, Phenol Process, and several chemical storage tanks. feedstock for manufacturing phenol and acetone. Phenol is an important chemical intermediate, which is mostly consumed in the production of phenolic resins and polycarbonates via bisphenol A. Cumene enters oxidizer, 12, through line 11 and reacts with air brought in through line 7 to form cumene hydroperoxide. Published December 2013. Therefore, the cumene and phenol markets are strongly tied. The plant where you are employed has been buying cumene to produce phenol. Someone has made a preliminary sketch for such a process and has submitted to the engineering department for consideration.

For the process to be economical, both phenol and the acetone by-product must be in demand. Capacity. Phenol Unit This unit is based on UOP’s CUMOX process, which is a commercially established Cumene per oxidation process for the economic and efficient production of phenol and acetone. Cumene is isopropyl benzene. Temperature is 423 K. The product cumene hydroperoxide is heated with dilute sulphuric acid. Management is considering manufacturing cumene rather than purchasing it to increase profits. In 2010, worldwide demand for acetone was approximately 6.7 million tonnes, 83 percent of which was satisfied with acetone produced by the cumene process. The company, owned jointly by Shawinigan Chemicals and British American Oil Co., Ltd., is operating under license from Hercules Powder and Distillers Co., Ltd. 1 shows the key steps in the previously practiced process of preparing phenol and acetone from cumene. THE first plant to produce phenol and acetone from petroleum, through oxidation of cumene, went into operation last week when B. A.-Shawinigan Ltd. officially opened its plant at Montreal. Cumene Process for manufacturing phenol The cumene process, i. e., the proton-catalyzed cleavage of cumene hydroperoxide to and acetone, was discovered by Hock and Lang in 1944. It decomposes to phenol and … The catalyst is cobalt naphthenate. economic feasibility of developing a new cumene production process an existing plant site for the synthesis and purification of cumene with an output goal of 100,000 metric tons per year for a plant life of 15 years. FIG. From 1993 to 1998, world cumene demand grew at a rate of 4.7%/yr, increasing from 5.6 million to 7.1 million t/yr.
