Environmental Control
In addition, HRS Spiratube has developed the systems shown below for evironmental
applications.
Systems for concentration using Mechanical Vapour Recompression
(vapour recompression system) and Systems for Multiple Effect Evaporation
have been developed for the treatment of Industrial residues.
Principle characterístics:
The Systems for Concentration using Mechanical Vapour Recompression
incorporate the Unicus® dynamic scraped surface
heat exchanger as an evaporator which, when coupled with the mechanical
recompression of vapour gives the following advantages:
- The Unicus® dynamic scraped surface heat exchanger guarantees the absence
of fouling within the evaporator which allows it to work for as long as
necessary without stopping.
- The Unicus® dynamic scraped surface heat exchanger allows high levels
of concentration.
- The mechanical recompression of vapour is the key to energy saving.
Applications:
- Concentration of waste water and sludges by evaporation of the water or other volatile
liquid components.
- Recovery of costly solvents or contaminants from sludges by condensation.
- Crystallization by means of evaporation and concentration.
- Dehydration of organic residues.
- Treatment of slurries of animal waste.
- Drying.
The Multiple Effect Evaporation Systems also include the
Unicus® dynamic scraped surface heat exchangers, which are the ideal
partner for the concentration processes of waste products when associated with
electrical cogeneration, which produce useful quantities of hot water
or exhaust gases from which valuable energy can be recovered. The advantages
are:
- Absence of fouling.
- Long operating times.
- High levels of heat transfer.
Applications:
- Especially suited for processing critical residues such as residual water from chemical
and petrochemical plants which are difficult to treat in other ways.
