Membrane-Assisted Condenser
Abstract
:1. Introduction
2. Description of the Technology
- -
- traditional condensers represent the easiest process even if corrosion phenomena due to the presence of acid pollutant in the waste gases stream are their main limitation;
- -
- adsorption of water by a liquid or solid desiccant is another valid alternative despite desiccant losses, cost and regeneration of adsorbent, and low quality of water are the main drawbacks;
- -
- high energy consumption due to the high pressure requirements is associated with the utilization of dense membrane for the recovery of water vapor from the gaseous streams.
- -
- no corrosion phenomena because membrane can be fabricated from almost any chemically resistant polymers with hydrophobic intrinsic properties;
- -
- energy consumption of a MC is lower with respect to that of either cryogenic separation or dense membrane, due to the high difference in boiling point between the gases and water in the first process and due to the high pressure requirements in the second process;
- -
- with respect to liquid or solid sorption, a MC is not effected by problems such as desiccant losses, cost and regeneration of adsorbent, and low quality of the produced water.
3. Methods
4. Results
5. Conclusions
- -
- it does not suffer corrosion phenomena of traditional condensers because membrane can be fabricated from almost any chemically resistant polymers with hydrophobic intrinsic properties;
- -
- it can control the concentration of contaminants in the recovered liquid water.
