100 gmol/h methyl ethyl ketone (MEK) and 100 gmol/h of nitrogen are mixed and fed to a flash tank, from which vapor and liquid streams can be removed. Assume that the flash tank is at 80C and 3050 mmHg. Calculate the vapor and liquid flow rates and the composition of the vapor stream. Suppose the tank pressure is 3050 mmHg and only vapor is produced. What is the minimum tank temperature? Suppose the tank temperature is 80C and only vapor is produced. What is the maximum tank pressure? You can use Antoine equation and Raoult's law for MEK. Assume that none of the nitrogen dissolves in the liquid.
