CRYSTALLIZERS

A separate issue is the start-up of continuous crystallizers. It is generally recommended that at least 10 residence times are required for a continuous system to reach steady-state, though in practice some systems can take significantly longer. Thus, frequent startups and shutdowns of these types of equipment should be avoided.
