The catalyst is cobalt naphthenate. The plant where you are employed has been buying cumene to produce phenol. Capacity. Phenol and Cumene Process Summary PEP Review 2013-11. The company, owned jointly by Shawinigan Chemicals and British American Oil Co., Ltd., is operating under license from Hercules Powder and Distillers Co., Ltd. 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. 2 shows the integration of the topping column of the invention into the previously practiced process steps. A route analogous to the cumene process begins with cyclohexylbenzene. The facility consists of a Cumene Process, Phenol Process, and several chemical storage tanks. Benzene and propylene are reacted to form cumene and cumene hydroperoxide in the Cumene Process. feedstock for manufacturing phenol and acetone. Published December 2013. Phenol is an important chemical intermediate, which is mostly consumed in the production of phenolic resins and polycarbonates via bisphenol A. FIG. 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. Someone has made a preliminary sketch for such a process and has submitted to the engineering department for consideration. Phenol : 40,000 TPA; Acetone :24,640 TPA; The CUMOX unit has been divided into the following process section. Cumene in the global petrochemical industry is used primarily as a reactant for production of phenol. 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. 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. 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. FIG. Blue Island Phenol LLC is physically located in Alsip, Illinois, with a mailing address in Blue Island, Illinois. 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 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 is isopropyl benzene. It decomposes to phenol and … Therefore, the cumene and phenol markets are strongly tied. Cumene enters oxidizer, 12, through line 11 and reacts with air brought in through line 7 to form cumene hydroperoxide. 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. 1 shows the key steps in the previously practiced process of preparing phenol and acetone from cumene.
