Patent number: 5679241Abstract: The C.sub.2 to C.sub.5 and heavier acetylenes and dienes in a thermally cracked feed stream are hydrogenated without significantly hydrogenating the C.sub.2 and C.sub.3 olefins. Additionally, the C.sub.4 and heavier olefins may be hydrogenated. Specifically, the cracked gas feed in an olefin plant is hydrogenated in a distillation reaction column containing a hydrogenation catalyst without the necessity of separating the hydrogen out of the feed and without any significant hydrogenation of the ethylene and propylene. A combined reaction-fractionation step known as catalytic distillation hydrogenation is used to simultaneously carry out the reactions and separations while maintaining the hydrogenation conditions such that the ethylene and propylene remain substantially un-hydrogenated and essentially all of the other C.sub.2 and heavier unsaturated hydrocarbons are hydrogenated. Any unreacted hydrogen can be separated by a membrane and then reacted with separated C.sub.Type: GrantFiled: May 17, 1995Date of Patent: October 21, 1997Assignees: ABB Lummus Global Inc., Chemical Research & Licensing CompanyInventors: Stephen J.

Patent number: 5667157Abstract: The comminution apparatus comprises a drive shaft having a roller bearing which is disposed in a housing. A temperature detector mounted in the housing monitors the temperature of the roller bearing. Hydraulic fluid is supplied to a circumferential groove in the housing to apply hydraulic pressure to the outer raceway. The hydraulic fluid pressure is monitored by a pressure detector and gage and may be vented by a manually operated relief valve. The drive shaft is rotated at normal operating speed and normal load with the bearing clearance at maximum until the bearing reaches an equilibrium temperature. Raising the hydraulic pressure develops a force on the rear surface of the outer raceway, biasing the outer raceway towards the shaft and reducing the bearing clearance. Reducing the bearing clearance reduces waste heat generated by skidding between the rollers and the raceway.Type: GrantFiled: November 13, 1995Date of Patent: September 16, 1997Assignee: Andritz Sprout-Bauer, Inc.Inventor: Stanley R.
