Discussion
Arrange the steps of an isothermal flash calculation in the usual order.
1. solve the Rachford-Rice equation for the vapour fraction
2. check that the feed is actually between its bubble and dew points
3. compute the liquid and vapour compositions
4. estimate the K values at the given conditions
Answer: D
The check comes first because a feed outside that range is a single phase and the flash has no solution. Compositions follow once the vapour fraction is known, and the K values may then be updated and the loop repeated.
