Abstract

The invention concerns n apparatus for providing and distributing bubbles in a gas-liquid mix transported in a flow path of a pipe. The apparatus is arranged in line with the pipe and comprises in successive order an inlet region, an obstacle unit and an outlet region. The inlet region is arranged for the entering of gas-liquid mix containing initial sized bubbles, the inlet region is provided to accelerate and direct the flow into the obstacle unit. The obstacle unit is provided with structure elements to produce a turbulence whereby reducing the initial sized bubbles to smaller sized bubbles and dispersing the bubbles in the flow. The outlet region is arranged for the entering of the gas-liquid mix containing smaller sized bubbles and has provisions to accelerate the flow and maintain an even distribution of smaller sized bubbles in the flow for further transport in the pipe. The invention also include an method.
