Purpose
1.1. The laboratory catalytic dewaxing unit is designed to remove normal paraffinic hydrocarbons from oil fractions. Since normal hydrocarbons have a high pour point, their removal lowers the pour point of the oil fraction.
Catalytic dewaxing is characterized by the fact that at high pressure, temperature and excess hydrogen, long molecules of normal paraffins are split and isomerized.
2. Technical Specifications
2.1. The unit is a rack with shut-off valves, a heating reactor and a control unit attached to it.
2.2. Unit for electrical safety meets the requirements of class 1 type H in accordance with GOST 12.2.025-76.
2.3. Operating conditions:
· environmental temperature from +10 to + 35˚С
· relative humidity not more than 80% at a temperature of 25 ° C (77 ˚F);
· power supply - single-phase AC network with voltage of 220 V ± 10% and frequency of 50 Hz.
2.4. The average service life of the unit is 5 years.
2.5. Specifications are given in table. 1
