  • Quench process
    Patent number: 7273961
    Abstract: The present invention is a process for quenching a reactor effluent stream. The reactor effluent stream comprises water, olefin product, and methanol and is further entrained with catalyst fines. The process removes water, catalyst fines, and methanol. Particularly, methanol removal from the reactor effluent stream is improved.
    Type: Grant
    Filed: January 22, 2004
    Date of Patent: September 25, 2007
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Malcolm G. Pettigrew, Wadie Malaty, Ram Mohan Lai Mallik
  • Heat recovery from the effluent stream of an oxygenate-to-olefin process
    Patent number: 7271306
    Abstract: The present invention comprises a process for cooling a reactor effluent stream from a methanol-to-olefins reactor. The process is efficient and recovers heat from the reactor effluent stream in one or more highly usable forms, preferably high pressure superheated steam.
