ABSTRACT:
In an ebullated bed process it has been found that a hydroclone effectively removes gas from recycled liquid used to ebullate the catalyst bed. When a 5 psi or greater inlet head and 5 psi pressure drop from the hydrocyclone inlet to the liquid outlet is maintained, essentially all gas is removed form the recycled liquid. Stabilized recycle pump operation is experienced and steady state achieved thereby.
