There are four main process routes used to produce ethyl acetate. [1] [2] [3] This includes the ISBL costs, OSBL cost, Engineering Costs and Contingency cost. It is a reversible process and does not proceed to any appreciable extent in the absence of catalysts or supercritical condition (Chidi and Peter, 2016). Despite this there are still many locations where it is still possible to source ethylene and where this is possible the process is still attractive. Before this project is fully invested in, there are multiple experiments and investigations into assumptions that need to be performed to determine the effect of these assumptions on profitability. In addition, the Tishchenko reaction requires a supply of acetaldehyde, which may not be readily available and can be difficult to store and . For the 1st series of distillation column, light end are separated and this steam is further distilled to take non-converted acetaldehyde, which is returned to reactor. This is highly unlikely to be true, however. [] Its synthesis by reactive distillation[][] and by acceptorless dehydrogenative dimerization of ethanol has been explored. However the catalyst used is hard to manage and also the catalyst is homogenous and must be removed which is difficult but is manageable. Related Reactions The sulphuric acid removes water to help shift the equilibrium towards forming more ester product. The water from the reaction can be disposed of in many ways, if there is a river, lake or sea then it can be pumped there or if there are nearby chemical plants which require water as part of their process then they can be recycled there. 10 Math's Notes, Class Therefore from a technical standpoint the esterification method is indeed feasible to produce ethyl acetate and other aspects of the process will be researched further to ascertain if it is feasible in other aspects. and Bueno, J.M.C., 2014. 133, 4668-4671.

This process is a simple process, well known reaction, and moderately exothermic where the heat or reaction is -0.0114kJ/mol with no danger of decomposition reaction. Most of the ethyl acetate produced in Germany and Japan is manufactured through this process. In accordance with the HSE any new entrant at risk of carry dangerous substances must check at what stage must they adhere to the regulations (Health and Safety Executive, 2016). Global Politics A. Heywood. The Design brief states that a new plant which produces 200 kilo tonnes per annum of ethyl acetate must be built. This restriction means that the available options for a location to build the plant are very limited and because these are less common in Europe due to Europe not being a large petrochemical producer and the fact that the ethyl acetate produced is required specifically for the European market means that that the only viable options would be to import from outside Europe or build the plant outside of Europe both of which would be very costly. If a process safety culture is adopted and instilled into the employees and management of the ethyl acetate plant then this would reduce the risk of a safety incident occurring. Applied Catalysis A: General, 237(1), pp.53-61. This process occurs by the removal of hydrogen in ethanol to produce an acetaldehyde, the aldehyde is then added to ethanol to form a hemiacetal which in turn is dehydrogenated to generate ethyl acetate (Inui et al,2002). The aluminium alkoxide acts as a Lewis acid to coordinate with one molecule Resourses, Sample papers for A literature review. It consists of an ester, where the alcoholic component derives from ethanol, while its carboxylic acid component comes from acetic acid. Ans. Hazard and Operability study (HAZOP) study is the most widely used and preferred approach in the chemical plant to accomplish hazard assignment qualitatively and quantitatively. Catalyst deactivation over time was not taken into account in this analysis but is likely to be occurring and may affect the rates of reaction. This slowing of the reaction rates could potentially not only cause less product to be made, but also cause the composition into the distillation columns to drastically differ leading to failure of one of the columns. Silicotungstic acid is used to manufacture ethyl acetate by the alkylation of acetic acid by . Next, separator is needed to remove the residue that contain in the mixture. The most widely used modification to the Tishchenko reaction is the Evans-Tishchenko reaction that transforms a chiral betahydroxy ketone in the presence of an aldehyde and catalytic samarium iodide (SmI 2) into the anti-1,3-diol monoester with excellent diastereoselectivity.
