The consumption of energy by vertical transportation in general would be approximately 4-5% of the total  load.

In most refineries there is enough instrumentation and sampling/lab analysis done to calculate energy consumption continuously and verify hourly daily or monthly.  But it usually is not done. Energy optimization studies are often find great opportunities to improve efficiencies, reduce energy use save money and reduce ghg emmissons,
