What is the significance of setting specific vapor fractions in the FLASH$2$ units? How does this affect the composition and phase of the product streams?

For the FLASH$2$ blocks, what settings are required to achieve the specified vapor fractions of $0\mathrm{.}60$ and $0\mathrm{.}75?$ Explain the process variables that need to be controlled.

What key Aspen results do you look for to validate process specifications?

Think about how to make this process more energy efficient. Where could we use the energy again that's already been used somewhere else in the process?
