Expert Q&A Done BME 200 Conservation Principles in BME Take Home Exam Spring 2022 PROBLEM. Using fermentation to produce te materials for biodegradable polymers Biodegradable polymers have found increasing use in the medical field because they have the advantage of breaking down in the body after they have served their function Sample applications for biodegradable polymers are surgical stures and implants that are excreted or resorbed without surgical removal. Mose biodegradable substances are polymers of organic acids, and recent studies have shown that citric acid is a possible raw material Citric acid (CHO) is commercially produced by fermentation using the fungus Aspergillus in liquid media, under tightly controlled bioreactor operating conditions. The process involves growth of the microorganism in a fermenter with the addition of glucose, nutrients, water, and air that is bubbled through the fermentation broth As part of the evaluation of a proposed continous process steady-state, you have been asked to estimate the heating or cooling requirement of a fermenter that is to produce 1 kg or citric acid per hour. Feed to the unit includes a solution (stream 1) that is 23 mole glucose (CH20.), 0.5 mole ammonia, and the remainder water and dry air (21 mol %0.79%N:) providing a molar flow rate of oxygen twice that of the glucose (stream 2). Leaving the fermenter are a gas stream (stream 3) containing Nracted Os.Co, formed by fermentation, and 2 mole % water vapor, and a liquid stream (stream 4) containing fungal cell mass produced in the formonter (formula of CH, Nex) water, citric acid, and unreacted ammonin and glucose. The dry air input (stream 1) and all output streams are at 25C. The stoichiometry of the fermentation reaction is given by Hao (g) + 0. 196 NH (a + 1.8250 - 0.76.40(d+0.979 COM<:00 cog the following table gives data for selected process species information on other may be found in b.1 and b.2 canvas glucose citric acid ammonia fungal cell mw ar cp choose a basis. draw fully label flowchart of based this system is designed conversion limiting reactant. do degree- of-freedom analysis overall material balances only consider balance chemical that does not react production rate kgh determine total molar flow rates input output streams their compositions mole clearly show all equations used your solution find standard heat reaction fermentation kj if food enters bioreactor at temperature which heut must added to removed from fermenter have an enthalpy table. identify reference states top you assume aqueous are also zero how got specific enthalpies components>
