Patent number: 6199768Abstract: A liquid atomization process comprises forming a two-phase fluid mixture of a liquid and a gas, under pressure, dividing the fluid into two separate streams which are passed into and through an impingement mixing zone in which they are impingement mixed to form a single stream of two-phase fluid. The mixed, single stream is then passed into and through a shear mixing zone and then into a lower pressure expansion zone, in which atomization occurs to form a spray of atomized drops of the liquid. The impingement and shear mixing zones comprise respective upstream and downstream portions of a single cavity in a nozzle. This is useful for atomizing the hot feed oil in an FCC process.Type: GrantFiled: March 18, 1999Date of Patent: March 13, 2001Assignee: Exxon Research and Engineering CompanyInventors: Russell J.
