The method proposes to remove, by anionic or cationic exchange with a solid, the salts present in a solution of anti-hydrate agent used for the transport of the raw natural gas. After circulation in a pipe T with the raw natural gas, the solution The antihydrate agent is contacted with an anionic or cationic exchange solid in column B and C, to remove salts of the antihydrate solution. Then the anti-hydrate agent solution is depleted of water by distillation in column E. The regenerated solution is recycled. |
