the composition of the predicted overhead stream was calculated the acetate content of the reaction mixture was fixed at 30 kg sodium acetate fig3 shows acetate removed as a function of temperature and pressure the highest levels of acetate are removed at elevated temperature and low pressure fig4 shows that meg losses are highest at elevated temperature and reduced pressure therefore an optimum temperature pressure condition is required to maximize acetate removal while reducing or minimizing meg losses to acceptable levels fig5 plots acetate removal against meg loss for three temperatures 80 90 and 100 u00b0 c lower temperatures and low pressure are preferred to maximize acetate removal fig6 plots meg loss as a function of acetate rejected from the meg loop using simple blowdown 950 kg of meg will be ejected with every 30 kg of sodium acetate 44 kg meg per kg of acetate fig7 plots acetate removal as a function of temperature and pressure for three initial ph conditions 3 5 4 5 5 5 acetate removal efficiency is increased as the starting solution ph is reduced for a starting ph of 3 5 89 of the acetate in the reaction vessel is removed in the overhead stream at 100 u00b0 c and 0 1 bara compared to 48 3 for an initial solution ph of 4 5 and 8 8 for an initial solution ph of 5 5 using the acidification vaporization scheme practiced according to this invention can significantly reduce this meg loss at 80 u00b0 c and 0 15 bar the simulation software predicts 73 8 kg of meg in the overhead stream along with 8 75.
