Emulsion destabilization and grid cleaning in gas-oil separation plants and systems related thereto

A method comprising:

• providing a gas-oil separation plant system comprising:
• a high pressure production trap (HPPT) separator;
• a low pressure production trap (LPPT) separator in fluid communication with the HPPT separator;
• a dehydrator in fluid communication with the LPPT separator;
• a desalter in fluid communication with the dehydrator;
• a stabilizer column in fluid communication with the desalter;
• wherein a flowline interposes the LPPT separator and the dehydrator for introduction of a demulsifier chemical to the dehydrator, and
• wherein an emulsified crude is circulated between the HPPT separator, the LPPT separator, the dehydrator, the desalter, and the stabilizer column for separation of liquid hydrocarbons and saline water therefrom;
• and
• one or more recirculation flowlines for recirculating the emulsified crude or liquid hydrocarbons between one or more of the HPPT separator, the LPPT separator, the dehydrator, the desalter, and the stabilizer column to reduce or eliminate an amount of demulsifier chemical being introduced from the demulsifier flowline;
• and
• recirculating the emulsified crude or liquid hydrocarbons between one or more of the HPPT separator, the LPPT separator, the dehydrator, the desalter, and the stabilizer column within the one or more recirculation flowlines.
