Hazards Hazards in this experiment include, chemical hazards, heat burns, and potential falling object hazards. Isopropanol is an eye and mild skin irritant [1]. Thus, eye protection should be worn when handling this material. Direct contact with pure isopropanol, or the binary mixture, should also be avoided. If the mixture does come in contact with the skin, the skin should be washed with soap and water. During the distillation process, the mixture is being heated to its boiling point. The samples are collected at this elevated temperature, and precautions, such as heat resistant gloves, need to be taken to prevent burns. Collecting samples from the upper trays on the distillation column requires the use of a platform. All samples should be collected slowly, and vials not being used should not be placed on the platform. The vials should be transported carefully up and down the platform. An additional note, the power dial on the control panel should not be moved past 60% power since it could cause a fuse to blow. Theory The purpose of this experiment is to determine the steady-state composition profile of an isopropanol-water mixture and the overall tray efficiency of a fractional distillation column.…show more content…
A binary mixture being distilled is heated, and as the temperature of the mixture increases, one of the components begins to vaporize. The vaporized component rises in the column, while the liquid component remains at the base. Ideally, the two components would completely separate into pure substances given enough time. However, in this experiment the distillation column will be operated at the point of total reflux, meaning that the mixture will continuously undergo the vaporization and condensation processes with negligible

    BIOFUELS Two problems roused the world’s concern in recent years. One is energy crisis caused by the squandering of petroleum fuel. Second problem is environmental problems such as greenhouse effect, global warming, etc. To deal with such problems, renewable sources, utilization technology and bioenergy production technology have been developed. Bioethanol as one of the biofuel can be blended in different proportions in automobiles with gasoline. Biobutanol is also a new biofuel (Liu, Wang, & Zhang

    CHAPTER: 1 EXECUTIVE SUMMARY Petroleum is one of the primary sources of energy. It is the back bone of industries. It goes through a long chain from exploration to retailing- before it is available for usage in different forms. In our country, the Refining business is primarily dominated by Public Sector Undertaking Companies like Indian Oil Corporation Ltd. (IOCL), Bharat Petroleum Corporation Ltd. (BPCL), Hindustan Petroleum Corporation Ltd. (HPCL), etc. Apart from PSUs, major player in this sector
