Abstract:

A main tee with separate clips affixed on its ends for splicing the tee with identical tees in end-to-end butt joints. The tee and clip form a pocket for receiving the projecting end of an opposing clip with a uniform low insertion force. The clip is self-aligning with the pocket and when interconnected the clips precisely align the coupled tees both vertically and horizontally. The clips, formed of relatively strong material, have mutually engageable locking surfaces that ensure a strong joint.

Abstract:

An improved deoiling process is provided for removing substantial amounts of oil from spent catalyst withdrawn from resid hydrotreating units. In the process, a slurry of spent catalyst and oil is spirally conveyed at an upward angle of inclination in a spiral classifier. Oil is drained from the upwardly spiraling slurry to substantially separate the oil from the spent catalyst. The deoiled catalyst is discharged into a catalyst bin. Preferably, the bin is continuously weighed as the deoiled catalyst is discharged into the bin. The flow of deoiled catalyst into the bin is stopped when the weight of the catalyst-laden bin has reached a preselected weight.
