Graphene Oxide Membranes Could Reduce Paper Industry Energy Costs The U.S. pulp and paper industry uses large quantities of water to produce cellulose pulp from trees. The water leaving the pulping process contains a number of organic byproducts and inorganic chemicals. To reuse the water and the chemicals, paper mills rely on steam-fed evaporators that boil up the water and separate it from the chemicals. Water separation by evaporators is effective but uses large amounts of energy. That’s significant given that the United States currently is the world’s second-largest producer of paper ...

Cyclic distillation: A novel enhanced technology for processing hydrocarbons and derivatives Distillation is the most widespread separation method in history. Distillation is the most widespread separation method in history.1 Despite its simplicity and flexibility, distillation remains a very energy-inefficient process. Novel distillation concepts based on process intensification (PI) principles can deliver major advantages in terms of significantly lower energy use and reduced capital costs while improving ecological efficiency. The PI concept has been around since the mid-20th century, but...
