hi all 

how wax molecules ( heavy paraffins) are defined in  process simulation software such as pro ii and aspen?

Is ther any simulation model for lube oil dewaxing ?

Best Regards

Typically choose a heavy petroleum component for wax when used in distillaiton. Boiling point will be high. In real life, high temperatures can lead to degradation that is not easily reflected in simulations. I've never built lube oil dewaxing models and do not have any examples.

I’d choose about a C30 paraffin, unless an analysis is available.
