1. Optimization of operating conditions of integrated mixer

在产品的质量要求得到有效的前提之下，对装置工作过程中的操作条件进行合理的优化是一种有效的手段，而且相对而言其投资较少、易于推广使用。为其良好的效果对其配置适用的监测以及调控手段，有效控制过气化率以及调整回流比是其中效果比较理想的手段。

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、减少蒸汽用量

2. Reduce steam consumption

常减压蒸馏装置对蒸汽进行回收相当困难，尽Ψ大可能的减少对蒸汽的使用是非常有效的措施。由于不同性质的0，决定着生产方案不同，不同产品的质量也存在差距，对此就应该根据不同情况对蒸汽用量进行及时的调节，同时还可以根据0性质以及减压塔顶不凝气体的量对蒸汽用量进行合理的调整。

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、减少用电量

3. Reduce power consumption

据相关资料统计，仅电耗在炼油厂总能耗中就占据高达近百分之十五的比例。在炼油厂正常生产过程中，一些机泵流量及扬程过大是电耗过高的主要原因。因此，减少用电量在一定程度上可以有效降低装置的能耗，在满足不同工况要求的前提下采用变频调节技术的是Ψ有效的减少用电量的措施。除此之外，系统改造电脱盐对节约电量也有着不错的效果。

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、优化装置换热网络

4. Optimization of heat exchanger network

在常减压蒸馏生产中有大量的换热过程，可以利用回收部分热量的方式来减少装置供能损耗。目前对减压装置而言，要想进一步提高热回收率，低温热源利用的问题是重中之重。可以从两个方面对此问题进行:在工艺流程上和换热网络上采用较为的技术; 另外就是对换热器的合理利用。

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.
