Keywords: petrolatum, ceresine, de-oiling, crystal structure.Abstract. The paper shows the possibility of obtaining a low-oil base for production of petroleum ceresins by de-oiling of petrolatum separated from residual raffinates produced at the enterprises of PJSC «LUKOIL». The results of research of influence of solvent composition and its multiplicity to the feedstock, final cooling temperature and number of de-oiling stages on product yield and its properties: drop point, needle penetration, oil content and kinematic viscosity are presented. Optimal values of technological parameters of de-oiling for different residual raffinates are established, possibility of production of ceresine with improved quality indicators is shown.
