Abstract
A process for extracting a condensable vapor from a supplied gas, comprising the steps of: i) condensing the condensable vapor by cooling the supplied gas at a condensing surface, such that the supplied gas is divided into at least one condensed fraction and a product gas; while ii) removing the at least one condensed fraction from the condensing surface by mechanical scraping means.
Claims28
A process for extracting a condensable vapour from a supplied gas, comprising the steps of:
- i) cooling the supplied gas at a first condensing surface;
- wherein said first condensing surface is temperature controlled to a first temperature for condensing a portion of the condensable vapour in the supplied gas, such that the supplied gas is divided into a preliminary condensed fraction and a process gas;
- while removing the preliminary condensed fraction at the first condensing surface with mechanical scraping means;
- and
- ii) cooling the process gas at a second condensing surface;
- Wherein at the second condensing surface is temperature controlled to a second temperature for condensing a further proportion of the remaining condensable vapour in the process gas, such that the process gas is divided into a subsequent condensed fraction and a product gas;
- while removing the subsequent condensed fraction at the condensing surface with mechanical scraping means;
- wherein the preliminary condensed fraction has a higher dew point temperature than the subsequent condensed fraction;
- and wherein the preliminary condensed fraction has a higher viscosity than the subsequent condensed fraction at any given temperature below the second temperature, and wherein the process further comprises the steps of:
- a) collecting the removed subsequent condensed fraction at a first location wherein said first location is temperature controlled to the second temperature;
- and
- b) conveying the subsequent condensed fraction mechanically from the first location to a second location;
- wherein said second location is temperature controlled to the first temperature for heating and/or vaporizing said subsequent condensed fraction to form a heated subsequent fraction;
- and
- c) collecting the removed preliminary condensed fraction at the second location;
- and
- d) conveying the preliminary condensed fraction and heated subsequent fraction mechanically from the second location to a third location;
- wherein said third location is temperature controlled to a temperature higher than the first temperature for heating and/or vaporizing said heated subsequent fraction and preliminary condensed fraction to form a concentrated condensable vapour;
- and
- e) extracting the concentrated condensable vapour from the third location.
