Pulse dosing is used to administer a cleaning formulation into a fluid process stream flowing through structural components of a processing facility. The fluid process stream may contain corn, corn-derived products, or a combination thereof, or the fluid process stream may contain a process condensate, a rinse fluid, a cleaning fluid or any combination thereof. The processing facility may be an ethanol processing plant, a protein processing plant, a corn oil processing plant, an ethanol and corn oil processing plant, an ethanol and protein processing plant, or an ethanol, corn oil and protein processing plant. Pulse dosing may include administering the cleaning formulation into the fluid process stream for a period of x seconds every y minutes, with no administration of the cleaning formulation between the periods of x seconds.

Provided are a separation tower and method for treating condensed water. In order to overcome the defects that an apparatus has high investment and energy consumption and requires high safety due to the need to use an organic phase as an extractant, the present disclosure provides a separation tower for treating condensed water. The water separation tower includes a tower body. Evaporation units for purifying the condensed water are disposed in the tower body. A final-effect condensation unit is disposed below the evaporation units and connected with a vacuum pump. The present disclosure has the following beneficial effects: 1) the gravity is used, thereby omitting an intermediate pump and saving the power cost and a matching control system; 2) a pressure difference between every two effect evaporation units is designed, and heat energy provided by a first-effect evaporation unit is continuously evaporated to achieve separation, so that subsequent effect evaporation units do not require external heat sources; and 3) the degree of integration is high, the sealing property is good, a vacuum is easy to realize, a subsequent vacuum system is small, the energy consumption is low, a device is small in occupied area, the construction and installation cost is low, and the operation is simple.

A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. Fresh liquid to be concentrated is also introduced into the re-circulating circuit at a rate sufficient to offset the amount of liquid evaporated in the flow corridor.

A liquid concentrator system includes a concentrator section having a gas inlet, a gas outlet, and a mixing corridor disposed between the gas inlet and the gas outlet. A liquid inlet is disposed in the mixing corridor between the gas inlet and a narrowed portion. A demister is disposed downstream of the concentrator section. The demister includes a liquid collector to remove liquid from gas flowing through the demister, and a reservoir that collects the removed liquid. A re-circulating circuit is disposed between reservoir and the mixing corridor to transport liquid within the reservoir to the mixing corridor, and a secondary re-circulating circuit includes a settling tank to separate saturated liquid and suspended solids. A custom brine mixing device is operatively coupled to the settling tank.
