Abstract

1457334 Recovering clean water HANOVER RESEARCH CORP 4 Oct 1974 [15 Oct 1973] 43209/74 Heading B1B Clean water is obtained from dilute dispersions, suspensions or solutions by (1) evaporating to obtain steam and a concentrate (2) condensing the steam (3) mixing the concentrate with a relatively non-volatile oil to obtain a mixture which will remain fluid and pumpable alfter the water content has been removed (4) evaporating the mixture to obtain steam and an anhydrous oil/solids slurry and (5) using the steam from step (4) as a source of heat in step (1). Step (1) may be carried out at 70-250‹F and step (4) at 160-400‹F. The process may be modified by adding a light, rolatively volatile oil bafore step (1) and separatinig any distilled oil components from the water condensed at step (2). The oil may be recovered from the anhydrous slurry and recycled. Steps (1) and (4) may be multi-stage evaporation steps. [GB1457334A]
