The company, owned jointly by Shawinigan Chemicals and British American Oil Co., Ltd., is operating under license from Hercules Powder and Distillers Co., Ltd. Benzene and propylene are reacted to form cumene and cumene hydroperoxide in the Cumene Process. For the process to be economical, both phenol and the acetone by-product must be in demand. 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. Phenol and Cumene Process Summary PEP Review 2013-11. FIG. Phenol is an important chemical intermediate, which is mostly consumed in the production of phenolic resins and polycarbonates via bisphenol A. Temperature is 423 K. The product cumene hydroperoxide is heated with dilute sulphuric acid. 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. The catalyst is cobalt naphthenate. 2 shows the integration of the topping column of the invention into the previously practiced process steps. Cumene enters oxidizer, 12, through line 11 and reacts with air brought in through line 7 to form cumene hydroperoxide. Cumene is isopropyl benzene. Capacity. The plant where you are employed has been buying cumene to produce phenol. Published December 2013. Phenol : 40,000 TPA; Acetone :24,640 TPA; The CUMOX unit has been divided into the following process section. FIG. A route analogous to the cumene process begins with cyclohexylbenzene.

It decomposes to phenol and … 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. 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. 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. feedstock for manufacturing phenol and acetone. Therefore, the cumene and phenol markets are strongly tied. 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. Blue Island Phenol LLC is physically located in Alsip, Illinois, with a mailing address in Blue Island, Illinois. Cumene in presence of sodium carbonate is oxidised by passing air or oxygen. Cumene in the global petrochemical industry is used primarily as a reactant for production of phenol. Management is considering manufacturing cumene rather than purchasing it to increase profits. The facility consists of a Cumene Process, Phenol Process, and several chemical storage tanks. Someone has made a preliminary sketch for such a process and has submitted to the engineering department for consideration. 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.
