Study Notes
Solvent Strainers and Drums
- F-600A/B (Solvent Strainers) remove entrained solids from solvent wash.
- D-600 (Solvent Wash Drum) dimensions: 12’ diameter, 15’10” length, provides constant solvent feed to reactors R-201-205.
- In D-600, liquid solvent enters from the top and exits from the bottom, while vapor leaves from the top.
Condensers and Drums
- E-610 (Solvent Condenser) cools and condenses overhead vapor from D-600 and D-610 using a shell and tube design, with cooling water on the tube side.
- D-620 (Clean Solvent Drum) dimensions: 11’ diameter, 20’ length, receives fresh make-up solvent and condenses vapor from D-600 and D-610.
- In D-620, liquid enters from the top and exits from the bottom; vapor exits at the top and flows back in as liquid.
Additional Condensing and Pumping Equipment
- E-620 (Solvent Wash Condenser) cools and condenses vapor from D-620, sending a purge stream to the Purge Gas Header.
- P-610 (HP Clean Solvent Pump) routes solvent from D-620 to D-600 and recirculates it. It is a single-stage centrifugal pump driven by a 40 HP, 3550 RPM electric motor.
- P-620 (LP Clean Solvent Pump) also routes and recirculates solvent between D-620 and D-600, driven by a 15 HP, 1760 RPM electric motor.
Blow Down Drum and Vaporizer
- D-610 (Solvent Blow Down Drum) dimensions: 6’ diameter, 17’ length, separates liquid spent solvent from vapor spent solvent. Liquid exits the bottom, vapor exits the top.
- E-615 (Solvent Vaporizer) vaporizes liquid solvent from D-600 using 400 psig steam, employing a shell and tube design to vaporize lighter components.
Solvent Circulation Pumps
- P-600A/B (Solvent Circulation Pumps) transfer solvent from D-600 to reactors R-201-205 and back, utilizing multiple-stage, deep well centrifugal design and powered by 500 HP, 3560 RPM electric motors.
