✦ Synopsis
Carry over of a few high boiling organic compounds in multistage flash evaporation (MSF) plants was studied using a bench top experimental set up. Eighteen known organic pollutants; i.e., nine phenols (phenol, 2,4dichloro-, 2,4,6-trichloro-, 2,3dichloro-, 4-chloro-, 4-bromo-, 2,4-dibromo-, 2,6dibromo-and pentachloro phenols), five polycylic aromatic hydrocarbons (naphthalene, anthracene, chrysene, benzo(a)pyrene and dibenzo(a,h)anthracene), three phthalic acid esters (dimethyl, diethyl and di-n-butyl esters) and a high molecular weight nalkane (tritetracontane) were selected for the studies at three plant operation conditions: (1) 95OC, 630 mm Hg, (2) 800C, 350 mm Hg and (3) 500C, 90 mm Hg corresponding to lst, 5th and 15th stages of the MSF plant. Effect of an external deaerator to remove the organics through the vent system was also tested. Experimental results have been discussed in correlation with the temperature and vacuum conditions employed in the experimental set up.
