Apparatus for use with a natural gas dehydrator wherein a portion of the wet glycol in an emissions separator is pumped under pressure as circulating wet glycol which may be used as a coolant for effluent removed from a reboiler and/or a power source for an eductor to form a vacuum in a first chamber of a liquid water removal separator apparatus. The cooled effluent, comprising at least liquid water, liquid hydrocarbons and uncondensed vapors, moves into the first chamber wherein the liquid water and/or the liquid hydrocarbons are separated from the uncondensed vapors. At least, the uncondensed vapors are removed from the first chamber and move into the eductor wherein they are compressed and combined into the circulating wet glycol. The separated liquid water is transferred to a second chamber of the liquid water removal separator apparatus and then removed therefrom. In some instances, the liquid hydrocarbons are transferred to a third chamber and removed therefrom. Apparatus is also provided to remove liquid hydrocarbons from the emissions separator. Also, gases from gas emitting level control apparatus are collected and fed into the first chamber.

1. In apparatus for use with a natural gas dehydrator wherein a supply of natural gas is fed into an absorber wherein it is subjected to dry glycol to remove undesirable materials, including water, therefrom so that the dry glycol is changed into wet glycol that is removed from the absorber, the method comprising:providing first separator apparatus containing a supply of wet glycol and located to receive wet glycol from said absorber; transferring at least portions of said wet glycol in said first separator apparatus to a still column of a reboiler apparatus using a first transfer apparatus so that said transferred portions of said wet glycol can be changed to at least dry glycol and effluent; transferring said effluent from said still column to condenser apparatus using a second transfer apparatus; converting said effluent into at least liquids and uncondensed vapors in said condenser apparatus; providing second separator apparatus; transferring said liquids and said uncondensed vapors to said second separator apparatus using a third transfer apparatus; circulating other portions of said wet glycol from said first separator apparatus in a circulatory path and returning said other portions of said wet glycol to said first separator apparatus; separating at least said uncondensed vapors from said liquids in said second separator apparatus; and entraining and compressing said uncondensed vapors into said circulating other portions of said wet glycol to be returned therewith to said first separator apparatus.
