Alaqua - Mechanical Vapor Recompression (MVR)

Energy Consumption
Since prices for steam and electricity vary by region, the choice between MVR and TVR (and in the case of TVR, the number of stages) depends on local prices, possible utilization of hot condensate, and depreciation of the capital cost. Generally a TVR has lower CAPEX but higher OPEX, whereas an MVR has higher CAPEX but lower OPEX which makes it attractive. Both systems produce the same product quality as long as certain critical design parameter requirements are met.

1. External straight tube preheaters give short residence time, better deaeration of the calandrias, and easy inspection and cleaning.
2.  Pasteurizing systems (indirect or direct) meet the most stringent product specifications.
3.  Static liquid distribution system ensures that all tubes in the calandrias receive equal amounts of liquid at all times and can accept wide variations in liquid flow and flash vapor.
4. Freestanding design reduces floor space requirements and building costs, and is flexible in arrangement for installation in existing buildings.
5.  Efficient liquid-vapor separation results from controlled vapor velocities with tangential inlet and outlet ensuring minimum pressure losses.
6. Cleaning costs are minimized by CIP procedures, which may be fully automated.
7.  Instrumentation is per customer requirements, including PLC that can optimize product output and quality.
