Pour Point Depressants

A pour point depressant additive has been developed to reduce the pour point of paraffinic oils. The depressant contains a (non-ionic) surfactant, a depressant component and a solvent. The depressor properties of the developed compositions have been studied. It has been established that while adding the compositions to the oil mixture, at a concentration of 0.02% wt. the pour point decreases from +31 oC to -3 - +7 оС, and at a concentration of 0.04% wt. up to -5- + 4 оС. Under the effect of the developed compositions the oil viscosity at + 35 оС decreases from 46.3 mPa·s to 22.1-27.7 mPa·s, and at + 40 °C - from 38.2 mPa·s to 16.6-21.6 mPa·s. Viscosity reduction performance at the indicated temperatures are 40.2-51.6% and 43.5-56.5%, respectively. Compositions 8, 14 and 17 exhibit higher depressor properties.
