Abstract
A chloride salt eliminator system and method for removal of chloride salt from glycol circulated through a reboiler in natural gas dehydration, in a continuous process, close to the wellhead. Hot glycol from the reboiler is pumped into a salt eliminator unit having independently replaceable filter elements which trap chloride salts which are not soluble in hot glycol and pass clean glycol for return to the reboiler.
Claims1
A chloride salt eliminator method comprising:
- (i) providing a chloride salt eliminator system comprising:
- (a) a salt eliminator unit having a unit inlet and a unit outlet;
- (b) a plurality of filter elements arrayed within said salt eliminator unit;
- (c) a pump having a pump motor, adapted to pump glycol from a reboiler, into said unit inlet, through said filter elements, and out of said unit outlet back into the reboiler;
- and
- (d) a pump controller adapted to control operation of said pump;
- (ii) transporting said chloride salt eliminator system to wellhead site;
- (iii) installing said chloride salt eliminator system at the wellhead site;
- (iv) connecting said chloride salt eliminator system to the glycol reboiler of the natural gas dehydration equipment at the wellhead site;
- (v) operating said chloride salt eliminator system in a substantially continuous process;
- (vi) changing said filter elements, independently, as needed;
- and
- (vii) removing chloride salts from the glycol circulated through the reboiler.
