TECHPERT Process Industries has technical expertise in process and mechanical design of various application Forced Circulation Evaporators. Our capacity varies from 100 liters per hour 20000 liters per hour. Force is used to drive the liquid through the evaporator tubes thus producing high tube velocities. A high efficiency circulating pump, designed for large volume and sufficient head, is used to supply the force. Proper design results in controlled temperature rise, controlled temperature difference and tube velocities that give optimum heat transfer. Forced Circulation Evaporators are recommended for viscous, scaling and salting liquids. As the liquid is only heated in the calendria with flashing taking place in the separator and no boiling taking place within the tubes, fouling on hot tube walls is reduced. TECHPERT Forced Circulation Evaporators vertical calendria. The circulating pump withdraws liquid from the lower part of the vapour-liquid separator and circulates it through the tubes at a high velocity. Boiling is suppressed in the tubes either by liquid head or an orifice plate. The heated liquid is discharged into the separator where the vapour flashes off due to the temperature difference and is removed through the top outlet. The liquid is discharged at a maintained liquid level.

Multiple Effect
TECHPERT Process Industries has technical expertise in process and mechanical design of various application Multiple Effect Evaporators. Our capacity varies from 3000 liters per hour 50000 liters per hour. A multiple-effect evaporator, as defined in chemical engineering, is an apparatus for efficiently using the heat from steam to evaporate water. [1] In a multiple-effect evaporator, water is boiled in a sequence of vessels, each held at a lower pressure than the last. Because the boiling temperature of water decreases as pressure decreases, the vapour boiled off in one vessel can be used to heat the next, and only the first vessel (at the highest pressure) requires an external source of heat. Evaporators with more than four stages are rarely practical except in systems where the liquor is the desired product such as in chemical recovery systems where up to seven effects are used. Multiple effect evaporation commonly uses sensible heat in the condensate to preheat liquor to be flashed. Multiple Effect Evaporators are used in Milk Powder, Fruit Powder Plants for concentrating it before spray drying. It is used in Chemical, Pharmaceutical and Zero Liquid Discharge effluent treatment Plants.
