Process for phase separation

摘要: This invention provides a continuous process for separating gaseous phase from hydrocarbon liquid containing carbonaceous particulates and gases. The is fed to cylindrical separator, with the being removed therefrom as an overhead product, whereas are withdrawn bottoms product. By feeding tangentially separator maintaining particulate-liquid slurry downward velocity of about 0.01 0.25 fps in total solids weight percent 0.1 30%, temperature 550° 900° F., residence time 30 360 seconds, length/diameter ratio 20/1 50/1, so that characterization factor, α, defined ##STR1## DOES NOT EXCEED ABOUT 48 (°R sec 2 )/ft, deposit materials on interior surface may be substantially eliminated.
