Oil refineries different units of the refinery, one of the viscosity reduction unit which reduces the viscosity of the feed unit in a vacuum distillation tower Thmandە with additional bearing material is wax. This material is heated to about 460-480 ° C. Products with lower viscosity fuel oil system, some gas is heavy and sulfur gasoline. For new designs Haysys can quickly create models for the evaluation of multiple options. After selecting the best projects can be very realistic models created on the basis that additional equipment and procedural details are also to be taken into account. Haysys can improve quickly with complex operations and to ensure correct operation. After Mass Flow simulation of exhaust gas from the top of the tower from 6153 to 6151 kilograms of product per hour is modified, and the naphtha output from the condenser from 9239 to 9250 kg per hour is increased, on the other hand to reduce the temperature of the fuel feed to the tower output from 53400 to 53090 kg per hour of the tower is reduced and the amount of tar output from 16010 to 16030 kg per hour tower is increased, reducing the temperature to increase the production of naphtha as well. In this section came to the conclusion that reducing the temperature at the top of the tower will also produce naphtha.
