a) Thermal Efficiency were Steady & Stable over trial period
b) G.O.R successfully maintained between 9 and 10
c) T.B.T. maintained in the range of 105-110°C
d) Albrivap DSB (M) A average dosage 2 ppm were successfully maintained
the unit clean
e) Analysis of the brine chemistry concluded that there would be no risk of
forming hard alkaline scale on the heat transfer surfaces This was confirmed
by the final inspection.
