Accumulation of liquids and gases in process vessels

In this chapter we will apply to typical process vessels the equations for the conservation of mass and of energy that were derived in Chapter 3, Sections 3.4, 3.S and 3.6. We will begin with the simplest system, namely accumulation of liquid at a constant temperature, and build up to consider more complicated systems where both a liquid and a gas are present, and where the temperature of each phase varies. In each case a full set of equations wilt be developed, and the solution cycle will be outlined.
