Crude oil steam distillation in steam flooding. Final report [PDF]

, 1980
Steam distillation yields of sixteen crude oils from various parts of the United States have been determined at a saturated steam pressure of 200 psig. Study made to investigate the effect of steam pressure (200 to 500 psig) on steam distillation yields indicates that the maximum yields of a crude oil may be obtained at 200 psig.

Three Dimensional Printing of Bioinspired Composite Aerogels for Solar Steam Generation

Advanced Energy and Sustainability Research, EarlyView.
Freshwater scarcity demands efficient purification strategies. Inspired by desert grasses, reduced graphene oxide‐doped polyacrylamide aerogels with longitudinal grooves are fabricated via high‐speed three‐dimensional printing and freeze‐drying. The biomimetic design enables dual‐mode water transport, achieving a capillary flow of 2.16 cm in 10 minutes
