The tasty morsels ◊ Systematically recover pressure let-downs & expansions (cryo…) with turboexpanders ◊ Motors; especially pumps (16 MW, $21M PV) Compressor Controls Corp. on all axial/centrifugal compressors Heat-exchange across trains between C 3 chillers Including throttling→ASDs shift, less piping/valve pressure drop (friction)—especially in submerged units ◊ 0.87→0.95 + PF; ø unbalance?; shade/whiten xformers ◊ Whiten in-sun cryo pipes, vessels, tanks ◊ Raise landscape albedo, cool site ~10–20 C˚? ◊ Compressors (many recips.), HVAC, buildings ◊ Optimize (or eliminate) the uses of compressed air
◊ ◊ ◊ ◊ Fin-fans (ubiquitous in big process plants) Minimize the generation and discard of waste heat; put it to a cascade of higher-value uses first A typical Asian-made fin-fan cell costs ~$18k, needs ~$13k worth of generation and distribution capacity, and uses ~$21k (20-year present value) worth of fuel gas at a cheap ~$29/T Micron-mist the inlet air to cool it by ~6–9 C˚ Best, right-sized motors + adjustable-speed drives (e.g., save ~85% of electricity when running at half-speed) ◊ Numerous aerodynamic improvements (~80% savings, some retrofittable) on the standard ~1940s technology would be feasible & valuable…
