1. Naphtha splitter change in design basis.
Initially 2 specs
ASTM D86 gap
RVP of light naphtha
2. Determine vessel thickness, weight so that temp drop is limited to match metallurgy temperature limit
3. Revamp - Column design pressure 3.5 kg/cm2g and FV. FV governing vessel wall thickness. increased design pressure to reduce relief load to existing flare
4. SWS - Suggested Pump around configuration
5. BPCL - hourly v/s daily labor rate in the proposal
6. Coal gasification - licensor selection - coal washing - water pollution
7. Fertilizer - Single large train for the given capacity
8. PSV - mechanical stop in CV
9. Combining NRU and thermal oxidizer
10. Reliance - Existing char filter was not functioning properly. Addition of cyclone with 10" W.C. pressure drop.
11. AUTO RECIRCULATION VALVE
12. Training program
13. Right at first pass. Take 10-20% additional time but reduce changes and corrections at later stage. When audit happened, project achieved better results than benchmark and other projects.
14. Mechanical stop on control valve to check relief load.
15. Asked to stop at acetic acid while project was to make Ethanol for fuel blending for better economics. Sale part acetic acid and use remaining for Ethanol production
15. Iocl DFR cw and power study
16. Add VFD on pump drive
