Method for negating deposits using turbulence

Patent ·
OSTI ID:1568151

A method for preventing fouling of an operating heat exchanger is disclosed. A carrier liquid is provided to the heat exchanger. The carrier liquid contains a potential fouling agent. The potential fouling agent is entrained in the carrier liquid, dissolved in the carrier liquid, or a combination thereof. The potential fouling agent fouls the heat exchanger by condensation, crystallization, solidification, desublimation, reaction, deposition, or combinations thereof. A gas-injection device is provided on the inlet of the heat exchanger. A non-reactive gas is injected into the carrier liquid through the gas-injection device. The non-reactive gas will not foul the heat exchanger surface and will not condense into the carrier liquid. The non-reactive gas creates a disturbance by increasing flow velocity and creating a shear discontinuity, thereby breaking up crystallization and nucleation sites on the surface of the heat exchanger. In this manner, fouling of the operating heat exchanger is prevented.
