Abstract
An apparatus and process for the controlled concentration of oil well brine which is adapted to be situated at a well site where oil well brine is produced and which evaporates water from the brine to cause precipitable salt to precipitate out of solution and to be recovered and to cause the remaining liquid to become concentrated with brine constituents which also are recovered.
