Abstract:
A method of evaporating a first medium using heat from a hot second medium, comprising the following steps:a) providing said first medium initially in a liquid state, and flowing said first medium in a first net direction;b) flowing said first medium in a second net direction substantially opposite said first net direction, with a first heat exchange wall between said first medium flowing in said first net direction and said first medium flowing in said second net direction;c) providing and flowing said hot second medium with a second heat exchange wall between said hot second medium and said first medium flowing in said second net direction;d) transferring heat from said hot second medium through said second heat exchange wall into said first medium flowing in said second net direction; ande) transferring at least some of said heat from said first medium flowing in said second net direction through said first heat exchange wall into said first medium flowing in said first net direction;wherein said step e) causes said first medium flowing in said first net direction to evaporate from said liquid state into a gaseous state.
