The article considers interactions between laser emission and process fluids surfaces during their solidification. Having studied the phase transition features, the authors propose a simplified model of crystallization of the process fluids containing paraffin. The model is compared with the experimental study using the laser phase analysis method. The model includes three main stages: amorphization, mixed phase, and crystallization, which are described in the article. The method of controlling the parameters of the process fluid phase transitions by means of laser emission is proposed. The method is versatile in terms of optical transparency of the samples, which became possible due to the analysis of laser emissions reflected from their surfaces, but not those penetrating the layer. Based on the experiments the authors suggest both a rapid analysis of process fluids and an automated laser set for its implementation.
