Abstract
Controlling the formation of crystalline hydrates in various fluid systems, most notably, gas and oil transmission pipeline systems by contacting the systems with certain polymers or polymers associated with solid particles. The polymers useful are chelating polymers capable of interacting with charged gaseous molecules such as carbon dioxide, by removing the carbon dioxide, or more practically by scavenging for the carbon dioxide, to prevent the methane or ethane hydrate structures from forming since they require carbon dioxide to stabilize their structures.
Claims10
A method of controlling the formation of crystalline hydrates in a fluid system, said method comprising
- scavenging and capturing charged gaseous molecules in said fluid by contacting said charged gaseous molecules with a polymer, said polymer having voids therein and said polymer being immobilized on a solid particle;
- seeding said charged gaseous molecules to grow micro hydrate crystals in said voids within said polymer;
- thereby preventing the agglomeration of said micro hydrate crystals outside said polymer.
