蒸氨生产以导热油代替蒸汽加热,原理是以焦炉煤气为燃料给导热油炉加热提高导热油温度,代替蒸汽用于蒸氨生产，目的是提高蒸氨效率，稳定生产，降低生产能耗，改善操作环境。导热油是一种有机载体，它具有良好流动性，耐高温，热稳定性好，抗氧化性强，导热系数大，无毒无味，无腐蚀。
用热媒介质代替蒸汽作热源，解决了蒸汽使用效率低、废水量大的问题，大大降低了能源消耗。
新蒸氨工艺与旧蒸氨工艺比较：不用蒸汽年少产生污水21.02万t，氨利用率提高78%，热效率提高54.2%，焦化工序吨焦能耗降低22.16kg标煤。即蒸氨塔中的直接蒸汽改为塔底出来的蒸氨废水用导热油间接加热后的蒸汽。
原理与粗苯的管式炉加热相似，就是用煤气加热，其实是导热油加热炉，把导热油温度加热后，用导热油来给剩余氨水加热，再用导热油给再沸器提供热源，用再沸器给蒸氨塔提供热源，这样剩余氨水就可以蒸氨了。总之，要有热源来给导热油加热。
蒸汽一直是焦化化工生产过程中所依赖的很主要的能源介质，人们并没有认识到它是一种劣质低效的能源。一方面是其本身传热效率不高；另一方面难以重复利用，变成冷凝水后成为生产污水。

Ammonia production with heat conducting oil instead of steam heating, the principle is to coke oven gas as fuel to heat conduction to improve heat conducting oil temperature, instead of steam for ammonia production, the purpose is to improve the efficiency of ammonia evaporation, stable production, reduce the production energy consumption, improve the operating environment. Heat conducting oil is an organic carrier, it has good fluidity, high temperature resistance, good thermal stability, oxidation resistance, thermal conductivity coefficient, non-toxic and tasteless, no corrosion.
With the heat medium instead of steam as a heat source, solves the steam use efficiency is low, the problem of large amount of waste water, greatly reduces energy consumption.
The new ammonia distillation and old ammonia process comparison: no steam was produced210200 t ammonia water, improve the utilization rate of 78%, thermal efficiency is increased by 54.2% tons of coke, coking process energy consumption reduced22.16kg of standard coal. The ammonia distillation tower in the direct steam to bottom out ammonia waste water with heat conducting oil indirectly heated steam.
Principle and crude benzol pipe type heating furnace is similar, with gas heating, is actually a heat conducting oil heating furnace, the heat conducting oil temperature after heating, the heat conducting oil to the residual ammonia by heat conducting oil heating, to provide the heat source with a reboiler, reboiler for ammonia evaporation tower provides a source of heat, such as residual ammonia water can the ammonia. In short, to heat to the heat conducting oil heating.
The steam has been the coking chemical process depends on the energy of the most media, people don't realize it is an inferior inefficient energy. One is its own heat transfer efficiency is not high; on the other hand, it is difficult to reuse, into a condensate into production wastewater.
