Acrolein is an impurity in our process so will not concentrate to the level that your process runs. However, we have used ASPEN physical properties with some limited success. I don't really have experience with pure acrolein but I do know that it loves to polymerize as you are no doubt aware. With this in mind, you must also take into account the pH of the system. Low pH (<5) will tend to allow acrolein to move overhead.
