1. Optimization of operating conditions of integrated mixer

在產(chǎn)品的質(zhì)量要求得到有效的前提之下，對裝置工作過程中的操作條件進行合理的優(yōu)化是一種有效的節(jié)能手段，而且相對而言其投資較少、易于推廣使用。為其良好的節(jié)能效果對其配置適用的監(jiān)測以及調(diào)控手段，有效控制過氣化率以及調(diào)整回流比是其中效果比較理想的手段。

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、減少蒸汽用量

2. Reduce steam consumption

常減壓蒸餾裝置對蒸汽進行回收相當(dāng)困難，盡Ψ大可能的減少對蒸汽的使用是非常有效的節(jié)能措施。由于不同性質(zhì)的0，決定著生產(chǎn)方案不同，不同產(chǎn)品的質(zhì)量也存在差距，對此就應(yīng)該根據(jù)不同情況對蒸汽用量進行及時的調(diào)節(jié)，同時還可以根據(jù)0性質(zhì)以及減壓塔頂不凝氣體的量對蒸汽用量進行合理的調(diào)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、減少用電量

3. Reduce power consumption

據(jù)相關(guān)資料統(tǒng)計，僅電耗在煉油廠總能耗中就占據(jù)高達近百分之十五的比例。在煉油廠正常生產(chǎn)過程中，一些機泵流量及揚程過大是電耗過高的主要原因。因此，減少用電量在一定程度上可以有效降低裝置的能耗，在滿足不同工況要求的前提下采用變頻調(diào)節(jié)技術(shù)的是Ψ有效的減少用電量的措施。除此之外，系統(tǒng)改造電脫鹽對節(jié)約電量也有著不錯的效果。

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、優(yōu)化裝置換熱網(wǎng)絡(luò)

4. Optimization of heat exchanger network

在常減壓蒸餾生產(chǎn)中有大量的換熱過程，可以利用回收部分熱量的方式來減少裝置供能損耗。目前對減壓裝置而言，要想進一步提高熱回收率，解決低溫?zé)嵩蠢玫膯栴}是重中之重。可以從兩個方面對此問題進行解決:在工藝流程上和換熱網(wǎng)絡(luò)上采用較為的技術(shù); 另外就是對換熱器的合理利用。

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.
