Oil Refineries Could Improve Energy Efficiency With New Method

Chemical plants spend from 50 to 70 percent of their energy in "separations," which are usually distillation steps required to separate a raw material into various products. An energy-efficient Purdue University method rearranges the distillation sequence needed to separate crude petroleum into products.

Fuel-Cell Water Separator

NASA Glenn Research Center has designed, built, and tested an innovative fuel-cell water separator that not only removes liquid water from a fuel cell’s exhaust ports, but does so with no moving parts or other power-consuming components. The separator employs the potential and kinetic energies already present in the moving exhaust flow.
