Process for preventing the formation of a solid phase from hydrocarbons in a fluid

A process for preventing a formation of a solid phase from hydrocarbons present in a fluid flowing in a pipe, which comprises at least a step of:

• subjecting the fluid in the pipe to a physical disturbance which vibrates molecules in the fluid and prevents organization of the molecules in the fluid and the formation of crystalline bonds in the fluid that produce the formation of the solid phase in the pipe;
• and wherein
• the physical disturbance is sent out intermittently in time in the form of pulses and/or wave trains.
