The Hammerschmidt equation (shown below) can be used to estimate the 'sub-cooling effect of a certain amount of a thermodynamic inhibitor: KT AT M(100-W) AT = sub cooling in C K = Hammerschmidt constant (MeOH = 2335, EtOH = 2335, MEG = 2700) M = molecular weight (MeOH = 32, EtOH = 46, MEG = 62) W = inhibitor wt% Use the Hammerschmidt equation to complete the table shown below: MeOH EtOH MEG wt% inhibitor 5 3.8 2.7 2.3 10 X 5.6 4.8 15 12.9 19.0 7.7 20 18.2 12.7 IY 25 24.3 16.9 14.5 If your process requires 10C of sub cooling to ensure no hydrate formation can occur, what is the minimum wt% of methanol and ethanol which needs to be added
