Abstract:
An apparatus for reclamation of a glycol based liquid used in gas dehydration, the apparatus comprising:at least one gas/liquid separator for removing fugitive gas emissions from liquid containing glycol;a thermal oxidizer in the form of an incinerator which is coupled to a fugitive gas emission line from the at least one gas/liquid separator whereby the thermal oxidizer oxidizes the fugitive gas emissions from the at least one gas/liquid separator, the thermal oxidizer having an exhaust gas outlet;a dual stream valve having a single inlet coupled to the exhaust gas outlet of the thermal oxidizer, the dual stream valve having a first outlet, a second outlet and means for adjusting the relative flow of exhaust gases through the first outlet and the second outlet;exhaust means coupled to the first outlet; anda reboiler coupled to the at least one gas/liquid separator whereby the liquid containing glycol can be introduced into the reboiler, the reboiler being coupled to the second outlet of the dual stream valve, such that exhaust gases diverted by the dual stream valve from the thermal oxidizer through the second outlet provide the heat necessary to operate the reboiler to boil the liquid containing glycol.
