Participation of chemical reagents in changing physico-chemical properties of fuel oil

Quality of process flows and commercial oil products deteriorates due to developing the deposits, which reduces the efficiency of heat and mass transfer and, accordingly, the clarity of rectification, resulting in changes in the component and fractional composition of the processed raw materials. There has been studied the influence of different chemical reagents introduced at the stages of production, treatment and processing of gas condensate and oil on the change in the physicochemical properties of the resulting dark oil products, which are responsible for deposit formation in the field and plant equipment during further processing or storage. The results of experimental studies are presented. Physicochemical properties of fuel oil are shown to be affected not only by the properties of the hydrocarbon feedstock, but also by the composition and concentration of chemical reagents introduced at different stages of production, field preparation and transportation. In the course of the experiment it has been stated that, depending on the concentration of the reagent and its main active substance, the structure of the oil system changes followed by the kinematic viscosity and pour point of the raw material. It has been found that chemical reagents improving the specified characteristics of oil products are able to worsen others.
