Abstract: The invention covers a method for treating spent regeneration gas from one or more molecular sieve treaters, first in an amine solvent unit and then in a caustic unit. The amine solvent unit removes hydrogen sulfide and carbonyl sulfide and the caustic unit removes mercaptans. Optionally, there are additional treatments before the treated gas has met specifications for burning as a fuel or used for other purposes.

Abstract: A tandem windshield wiper system including a first windshield wiper assembly having a first lever arm that is adapted to operatively move in a repeated wiping motion across the surface of a windshield. A second windshield wiper assembly having a second lever arm is spaced apart from the first windshield wiper assembly and is rotatable about a second wiper longitudinal axis and adapted to operative move in a repeated wiping motion across the surface of the windshield. A brushless DC motor that includes a planetary gear set having an output shaft is disposed between the first and the second wiper assemblies. The gear set is operable to reduce the speed of the rotational output of the motor through the output shaft of said gear set. A bellcrank having a central attachment point and a first and a second end is also included. The central attachment point is fixedly mounted to the output shaft of the motor.

Abstract: An apparatus is disclosed for improving the separation of fluids having different densities which apparatus employs a velocity reducing distributor for directing fluids in a vertical direction through a bed of packing to coalesce the fluids and a means to alter the direction of flow of the coalesced fluids to a horizontal direction. The disclosed apparatus is of particular advantage with respect to the gravitational separation of fluids having different densities which comprise an aqueous phase and a hydrocarbonaceous phase.
