LIQUID INVENTORY CONTROL IN AN EBULLATED BED PROCESS (D#78,872-F) The invention is an improvement in an ebullated bed process. Gas is removed the ebullated bed reactor preferentially to liquid. Gas is removed by material balance control until the reactor, including the recycle conduit is liquid full. Foam, generated around the recycle cup and riser conduits is floated upward by liquid and does not enter the recycle conduit. When steady state is achieved, liquid and gas are both removed from the reactor under material balance control. RAM ec:EX7K/09 |
