Abstract: The present invention discloses a comprehensive, efficient, and cost effective portable evaporator unit, method, and system for the treatment of brine. The evaporator unit, method, and system require a pretreatment process that removes heavy metals, crude oil, and other contaminates in preparation for the evaporator unit. The pretreatment and the evaporator unit, method, and system process metals and brine at the site where they are generated (the well site). Thus, saving significant money to producers who can avoid present and future increases in transportation costs.

Abstract: A blade heat exchanger includes blades that extend axially with respect to an axis of rotation and are elongated in the radial direction. The blades are arranged about the axis such that, when they are disposed in a housing, they form composite condensation and evaporation chambers that are isolated from each other. The interiors of at least some of the blades form the composite condensation chamber. The exteriors of the blades and the inner surface of the housing cooperate to form the composite evaporation chamber.

Abstract: Apparatus for the treatment of a wiping solution, which includes ink flocculation apparatus for flocculating ink contained in a used wiping solution by the addition of a flocculant to the used wiping solution; solid-liquid separation apparatus for separating, into sludge and a filtrate, the used wiping solution containing the ink which is flocculated by the ink flocculation apparatus through filtration of the used wiping solution; distilled water production apparatus for producing distilled water and a concentrated solution through heating of the filtrate which is separated by the solid-liquid separation apparatus; water recycling apparatus for recycling the distilled water which is produced by the distilled water production apparatus as a raw material of a wiping solution; and post treatment apparatus for separating the concentrated solution into steam and a solid residue through heating of the concentrated solution which is produced by the distilled water production apparatus.

Abstract: A distiller (10) that employs a rotary heat exchanger (32) introduces water to be evaporated into evaporation chambers (56). During most of its operation, it collects the water that has passed through the evaporation chamber (56) without evaporating, and it reintroduces the thus-collected liquid back into the evaporation chamber, where it also adds a minor amount of unrecirculated feed liquid to make up for evaporation and concentrate removal. Simultaneously, a minor amount of feed liquid is fed into one side of a transfer pump (116). During this mode of operation, the impurities concentration in the recirculating liquid tends to increase as a result of the evaporation of pure water vapor. Periodically, the erstwhile recirculating liquid is redirected to the other side of the transfer pump (116), where it causes the feed liquid stored in the transfer pump's first side to be fed without accompanying recirculant liquid into the rotary heat exchanger's evaporation chambers.

Abstract: A method for the treatment of a wiping solution, characterized by including: adding a flocculant to a used wiping solution for flocculation of ink contained in said used wiping solution; filtering said used wiping solution for separation of said used wiping solution into sludge and a filtrate; heating said filtrate to produce distilled water and a concentrated solution; returning said distilled water for recycling to serve as a raw material of a wiping solution; and heating said concentrated solution for separation of said concentrated solution into steam and a solid residue. An apparatus for performing the method of the present invention is also disclosed.
