Abstract
The present disclosure provides a method of dehydrating a feed stream processed in a distillation tower. The method may include (a) introducing a feed stream comprising a first contaminant stream into a distillation tower; (b) forming a solid from the feed stream in a controlled freeze zone section of the distillation tower; (c) feeding a second contaminant stream into the feed stream outside the distillation tower; and (d) removing water from the feed stream with a second contaminant stream by feeding the second contaminant stream.

A method of dehydrating a feed stream processed in a distillation tower, the method comprising:
- (a) providing the feed stream comprising a first contaminant from a gas reservoir;
- (b) determining the concentration of the first contaminant in the feed stream;
- (c) feeding a second contaminant stream into the feed stream outside of the distillation tower until the total amount of the first and second contaminant in the feed stream is greater than 25%;
- (d) after the second contaminant has been introduced into the feed stream, processing the feed stream in a dehydration unit to produce a dehydrated feed stream;
- and
- (e) introducing the dehydrated feed stream to a controlled freeze zone section of the distillation tower and forming a solid from the feed stream.
A method of producing hydrocarbons, the method comprising:
- (a) providing a feed stream from a gas reservoir comprising a hydrocarbon and a first contaminant;
- (b) determining the concentration of the first contaminant in the feed stream;
- (c) processing the feed stream in a dehydration unit to produce a dehydrated feed stream;
- (d) feeding a second contaminant stream into the dehydrated feed stream outside of the distillation tower until the total amount of the first and second contaminant in the dehydrated feed stream is greater than 25%;
- (e) introducing the dehydrated feed stream that comprises the first contaminant and the second contaminant to a heat exchanger;
- (f) introducing the cooled dehydrated feed stream to the controlled freeze zone section of the distillation tower and forming a solid from the feed stream;
- and
- (g) producing the hydrocarbon from the distillation tower after forming the solid.
