After the MVR starts up, steam is no longer required; only steam is needed to preheat the solution, and the amount of steam used is determined by the mass of the solution, the temperature difference, and the specific heat capacity, right?

Heat loss must be considered for any technology! 100% no supplementation! It’s impossible!

A small amount of steam still needs to be added to make up for the losses. The power consumption of a compressor depends on the boiling point of the material and the amount of work required; for example, 20 degrees is sufficient for steaming water, while 40 degrees is needed to steam sodium chloride solutions
