Mvr evaporator design pdf

The encon mechanical vapor recompression mvr evaporation process involves our forced circulation flash evaporator utilizing mechanical vapor compression. Evaporators and condensers in a new dimension the complete range. We define the evaporation process as one that starts with a liquid. A mechanical vapor recompression evaporator system is similar to a conventional steam heated, singleeffect evaporator, except that the vapor released from the boiling solution is compressed. This is a reduction of up to 99% compared to a 1 effect steam driven evaporator. Technology and applications gea engineering for a better. Operation the liquid to be concentrated is supplied to the top of the heating tubes and distributed in such a way as to flow down the inside of the tube walls as a thin film. Howden understands the unique process, aerodynamic, mechanical, and operations requirements of mvr applications, which differ from most any. Download fulltext pdf detailed design of a single effect evaporator with thermal vapor re compression thesis pdf available march 2016 with 4,990 reads. Mvr or mechanical vapor recompression also known as mvc is a technology where the vapor is compressed in a fan or a. Andritz mechanical vapor recompression mvr evaporator.

Since evaporation involves boiling, the gas sublayer in contact with the liquid phase in the liquidvapor interface will be comprised of generated steam. Mechanical vapor recompression blower and compressor. Evaporator types falling film evaporators design vertical shellandtube heat exchanger, with laterally or concentrically arranged centrifugal separator. Encon describes the different capacities that they can provide with their mvc waste water evaporators. Technology and applications evaporation technology using mechanical vapour recompression. By using this design, the encon mvc evaporator allows for minimal scaling, maximum uptime, and low operating costs. The epcon mvr evaporator only uses 840 kwh per ton evaporated water. Compared to multipleeffect evaporators, mvr evaporators consume considerably less energy. An evaporator for indirect heat transfer is only a modified heat exchanger.
