Artisan Industries Inc
Evaporator (Falling Film / Rising Film)
Product Description
The Rising Film Evaporator:
The Artisan Rising Film Evaporator is a vertical shell & tube heat exchanger generally used as a flash evaporator or pre-heater designed to remove most of the volatile components prior to stripping.
-
Feed enters tube-side from the bottom of the evaporator. As the liquid temperature increases, a rising film is formed on the tube wall, while most of the tube cross-sectional area is occupied by the vapor generated
-
The ascending force of vapor bubbles, which are produced during boiling, send the liquid and vapor upwards in parallel flow. Simultaneously the vapor rate also increases thereby forming a "Climbing" film on the walls of the tube. This co-current upward movement against gravity has the beneficial effect of creating a high degree of turbulence in the liquid. This is advantageous during evaporation of highly viscous materials and products that have a tendency to foul the heat transfer surfaces.
About Us:
For over 75 years the experienced chemical and mechanical engineers and the skilled manufacturing craftsmen of Artisan Industries have teamed to design processes and manufacture equipment to solve the most difficult technical problems in the chemical, petrochemical, food, pharmaceutical, waste reduction, energy and power industries.
The Separations Technologies group offers proprietary thin film processes and equipment to eliminate processing steps, reduce waste and increase profitability when evaporating, distilling, concentrating or drying heat sensitive, viscous or solids-containing materials. A custom-configured pilot plant facilitates the design of customized solutions for exceptionally challenging separations.
JET-VAC® supplies ejectors in many materials for generating vacuum from steam and other motive gases with no moving parts. Jet-Vac also offers equipment to chill water using steam including waste stream for chemical, petrochemical and power plant applications.
Custom Manufacturing and Product Development Services works with many local universities as well as start-up and established businesses in the extended New England area as a one stop source for prototyping, engineering, design development and manufacturing. Artisan specializes in pressure vessels, close tolerance machining of large components and specialty welding procedures.
With the recent addition of N and NPT certifications and an NQA-1 quality control program to its long held pressure vessel (U, U2 and R) certifications Nuclear Manufacturing now designs and manufactures equipment and components for the nuclear power industry and DOE facilities.
