1. A process for recovering energy in a petroleum, petrochemical, or chemical plant comprising:
- identifying a first fluid stream having a first control valve thereon in a process zone;
installing a first power-recovery turbine at the location of the first control valve;
directing at least a portion of the first fluid stream through the first power-recovery turbine to generate electric power therefrom; and
recovering the electric power.

Abstract
Power recovery turbines can be used debottlenecking of an existing plant, as well as recover electric power when revamping a plant. A process for recovering energy in a petroleum, petrochemical, or chemical plant is described. A fluid stream having a first control valve thereon is identified. A first power-recovery turbine is installed at the location of the first control valve, and at least a portion of the first fluid stream is directed through the first power-recovery turbine to generate electric power as direct current therefrom. The electric power is then recovered.

4. A process for recovering energy in a petroleum, petrochemical, or chemical plant comprising:
-
identifying a first fluid stream having a first control valve thereon in a process zone; installing a first power-recovery turbine at the location of the first control valve wherein the first power-recovery turbine replaces the first control valve; directing at least a portion of the first fluid stream through the first power-recovery turbine to generate electric power therefrom; and recovering the electric power.

20. A process for recovering energy in a petroleum, petrochemical, or chemical plant comprising:
-
identifying a first fluid stream having a first control valve thereon in a process zone; installing a first power-recovery turbine at the location of the first control valve; directing at least a portion of the first fluid stream through the first power-recovery turbine to generate electric power as alternating current therefrom; recovering the electric power; rectifying the recovered electrical power to direct current and inverting the direct current into recovered alternating current; and providing the recovered alternating current to a first substation.
