This disclosure describes energy efficient process to distill a process stream in a production facility. A process uses multiple effect evaporators, ranging from one evaporator to eight evaporators in each effect. The process arrangement shows an example of four effect evaporators, with a zero-effect evaporator having a single evaporator, a first-effect evaporator having a set of three evaporators, a second-effect evaporator having a set of three evaporators, and a third-effect evaporator having a set of evaporators to create condensed distillers solubles.

A method of purifying fumes with condensable gaseous contaminants is provided, including the steps of generating a flow of fumes to be treated in a heated area; cooling a structure receiving the flow of fumes so that the temperature of the structure is lower than that of the fumes to be treated to induce a condensation of the contaminants and to force a nucleation of the condensed contaminants; conveying said flow into an inertial separator unit for its purification. In particular, the structure is cooled by conduction through a natural and/or artificial cold thermal power source configured to stably and sensibly maintain its temperature below a fume temperature during the extraction of thermal power from the fumes by the structure.

A pyrolysis vapour condenser system (1) and a method for condensing pyrolysis vapour, the pyrolysis vapour condensing system comprising a condenser vessel (2), comprising a vapour inlet (3), and a cleaning device (9) for removing deposits from the vapour inlet (3). The cleaning device (9) is moveable between a cleaning position, in which it is disposed at least partially in the vapour inlet (3) for cleaning it, and a retracted position, in which the cleaning device (9) is retracted away from the vapour inlet (3) towards the condenser vessel (2).
