1. Optimization of operating conditions of integrated mixer
On the premise of effective product quality requirements, reasonable optimization of operating conditions in the working process of the device is an effective energy-saving means, and relatively speaking, it has less investment and is easy to popularize. For its good energy-saving effect, it is equipped with suitable monitoring and regulation means, and the effective control of over gasification rate and adjustment of reflux ratio are the ideal means.
2. Reduce steam consumption
It is very difficult to recover steam in atmospheric and vacuum distillation unit Ψ Reducing the use of steam is a very effective energy-saving measure. Different properties of 0 determine different production schemes, and there are differences in the quality of different products. Therefore, the steam consumption should be adjusted in time according to different conditions. At the same time, the steam consumption can also be adjusted reasonably according to the properties of 0 and the amount of non condensable gas on the top of the vacuum tower.
3. Reduce power consumption
According to relevant statistics, electricity consumption alone accounts for nearly 15% of the total energy consumption of refineries. In the normal production process of the refinery, the excessive flow and head of some pumps are the main reasons for the high power consumption. Therefore, reducing power consumption can effectively reduce the energy consumption of the device to a certain extent. On the premise of meeting the requirements of different working conditions, it is necessary to adopt frequency conversion regulation technology Ψ Effective measures to reduce power consumption. In addition, the system transformation of electric desalting also has a good effect on saving electricity.
4. Optimization of heat exchanger network
There are a lot of heat exchange processes in the production of atmospheric and vacuum distillation. The way of recovering part of the heat can be used to reduce the energy supply loss of the unit. At present, in order to further improve the heat recovery rate, it is a top priority to solve the problem of low-temperature heat source utilization. This problem can be solved from two aspects: adopting more advanced technology in process flow and heat exchange network; The other is the rational utilization of heat exchanger.
