CHE3049W – EFC Report

Synopsis

This report supplies a detailed exploration into the procedure of the Eutectic Freeze Crystallisation (EFC) procedure in order to identify its effectiveness as a parting technique for filter of waste water avenues. The objective of should be to evaluate the ability of the EFC process in reducing the volume of a your five wt% CuSO4 aqueous waste materials water stream significantly whilst simultaneously making potable (drinking) water. To be able to evaluate this kind of effectiveness, the yield and purity of only the glaciers product is looked into before and after several wash cycles. A 1000g solution of 5 wt% CuSO4 experienced crystallization for starters hour by using ice crystal seeding and the agitation of any stirrer by 500rpm. After the crystallization process, the mass of the ice cubes product and filtrate were recorded. The ice product was then cleaned with de-ionised water underneath Buchner vacuum filtration, prior to the masses were recorded once more. This process was repeated for 3 wash periods A sample with the ice item and filter were also considered before and after every wash, and these selections were analysed using Atomic Absorption Spectroscopy (AAS). A temperature probe revealed that the perfect solution did not reach the eutectic temperature of -1, 55⁰C during crystallization, and only reached a minimum temperatures of -0, 75 ± 0, 01⁰C. Despite this hot temperature, a significant fractional yield of ice product of 67, 05 ± 0, 01% was recorded. As predicted, the washing of the ice product reduced this yield to 52, 08 ± 0, 06% after three flushes. Furthermore, the process of washing was found to contaminate the pure cleansing water; as a result a ‘real' yield was calculated to be able to reveal the actual effectiveness with this process in producing fresh water.

After crystallization, a chastity of 98, 95 ± 0, 02% was attained, and the usage of three washes improved this kind of to 99, 96 ± 0, 01%. This proved the effectiveness of rinse cycles in increasing the purity from the ice item. In order to determine optimal functioning conditions with this process, the ‘real' yield was drawn against chastity, and it was found that you wash will optimize this method, producing 335, 04 ± 0, 05g of natural water, which corresponds to a fractional produce of 53, 37 ± 0, 01%, at a purity of 99, 54 ± zero, 02%.

Coming from these benefits, it was determined that the Eutectic Freeze Crystallisation process, functioning with only 1 wash, is an effective separation way of reducing a 5 wt% CuSO4 aqueous waste stream significantly when simultaneously creating potable drinking water.
