Industrial Evaporators
Evaporation equipment for concentrating a specified process liquid. ATTOMO reviews the feed, required concentration and utility conditions to select an appropriate arrangement.
Process and equipment approach
Falling-film, forced-circulation and scraped-surface arrangements suit different combinations of viscosity, fouling, solids and temperature sensitivity. Single-effect, multi-effect or vapour-recompression options need evaluation against the complete operating and energy balance.
Applications and product requirements
Evaporators concentrate liquids by removing a volatile component. The duty can involve solutions, selected suspensions or process residues, with the design governed by the final concentrate as well as the feed. This page compares equipment selection; the MEE page explains integration across multiple effects.
Equipment and operating approach
Falling-film evaporation can suit appropriate heat-sensitive liquids, while forced circulation can be considered where circulation and solids behaviour require it. Agitated thin-film or scraped-surface arrangements are separate options for suitable difficult products. Each has limits. Feed distribution, residence time, entrainment and fouling must be evaluated for the actual concentration range.

Materials and configuration
Heat-transfer surfaces, vapour bodies, pumps, separators, condensers and vacuum interfaces can be defined in the package. Materials must suit concentrated chemistry and cleaning exposure. Cleaning connections, access, drainability and the destination of condensate and concentrate should be included in the layout and scope.
Utilities and operation
Specify feed and outlet concentration, viscosity versus concentration, thermal sensitivity, boiling-point elevation and evaporation rate. Steam, waste heat or recompression options need a duty-specific assessment. Heat recovery may reduce purchased energy but does not remove the need for a verified mass and energy balance.

Frequently asked questions
How is an evaporator different from a dryer?
An evaporator normally produces a more concentrated liquid or slurry. A dryer is designed to obtain a solid product at a specified residual moisture. The process boundary determines which is needed.
Does vacuum operation guarantee no product damage?
No. Lower boiling temperature can help, but residence time, local surface conditions, oxygen exposure and product stability also matter.
What helps select between falling film and forced circulation?
Concentration range, viscosity, solids, fouling, thermal sensitivity and available temperature difference are key inputs. Trials may be needed for uncertain feeds.
