Natural Gas Dehydration Solutions

Can deliquescent desiccants be used in place of a TEG dehydrator? It's a good question, one we hear often. Usually Van Gas Technologies natural gas dehydration solutions are applied to dry moderate to small volumes of fuel gas and instrument gas. However, when the pressure and temperature conditions are right, GasDry desiccants can be used in place of TEG dehydration. Sometimes a gas producer or processor's overwhelming concern is eliminating emissions from a TEG dehydrator. In these cases deliquescent desiccants may be an attractive alternative to a TEG dehydrator. A TEG dehydrator does not "turn down" well. This means that variable gas flow rates cause TEG dehydrators to perform poorly. Desiccant gas dehydration systems will dehydrate natural gas at volumes below full system design capacity without losing dehydration efficiency.
