ABSTRACT
The observed reaction that took place in this experiment was the de-esterification of ethyl benzoate to form benzoic acid. This experiment was used to determine the rate constant k of the synthesis of benzoic acid at different temperatures and ethanol concentrations. The reaction was carried out in a batch reactor, where ethyl benzoate was added to a mixture of water, ethanol, and sodium hydroxide. The agitation speed of the batch reactor was kept

required reactor volume would be: cout cin exp PFR 1 cout ln K cin PFR V K Q 1 ln 50 0.1 h L 75 16.1 h s s 3600 h 39.1 h 1 m3 1000 L 10,560 m3 Note that the exponential equation for the PFR is applicable because we know that the reaction is first order. The PFR is obviously a much more efficient reactor to accomplish the treatment goal. (c) A PFR can be thought of as a batch reactor that is on a conveyor belt, or equivalently. Therefore, if the initial concentration in the batch reactor…

Essay about Cambridge Chemical Engineering Interim report Bioethanol 2013

downstream. 4. Area 3: Starch Hydrolysis & Saccharification The slurry is mixed with dilute sulphuric acid to pH 5 in a mixer prior to the addition of enzymes in insulated batch reactors. 70g/l starch is used to produce about 88g/l glucose without adverse viscous effects in these reactors. Using 18 200m3 reactors with a batch cycle of 4.5hrs (including 3hrs of fermentation), a continuous outflow is produced without the use of buffer tanks to prevent the profileration of microorganisms. At the end…

Oxygen Transfer In Water

operational conditions (E.g. Stirrer speed and oxygen flow rate), and formulate the optimal parameters for modelling a sewerage plant. In wastewater treatment plants, diffused air system bubbles are distributed from diffusers at the base of the reactor, where the rising bubbles come in contact with the aqueous layer (BLA). When equilibrium is reached, the liquid is ‘saturated’ into the gas. This can be modelled using equation 1, as proposed by Merchuk et al(1990), where Cl is the gas concentration…

Saponifacation of Ethyl Acetate and Soldium Hydroxide Essay

process of ethyl acetate using sodium hydroxide (NaOH) at 5 temperature between 15 and 25 degrees Celsius. Two trails were performed at temperatures 16, 18, 20, 22, and 24 degrees Celsius. The main equipment of the project were the jacketed beaker batch reactor and the LabPro conductivity probe. The solution’s conductivity throughout the reaction was collected and plotted in a linearized plot against time to…

'Manufacture of Hairspray and Dimethyl Ethle Production Essay

profit of aerosol hairspray production by analyzing and possibly optimizing their manufacturing process, mores specifically, the production of the most widely used aerosol propellant, dimethyl ether (DME). The optimization of a thermally coupled DME reactor (OTCDR) proves to be economical, energy sufficient, and increase the net profit of the industrial plant. It is in the best interest of industrial aerosol hairspray manufacturers to consider multiple alternative production…

MQP REPORT Essay

ABSTRACT This report focuses on the use of lab synthesized composite beads, made up of Xanthan Gum, Calcium Alginate and Na-A Zeolite, in adsorbing cobalt and nickel ions from nuclear power plant wastewater. The adsorption was investigated in a batch mode by changing relevant parameters including the adsorbent dosage, metal ions in solution, initial pH, temperature and salt concentration in the solution. Optimal conditions for the adsorption process were found to be pH=5 and an adsorbent dosage…
