Because the reaction process of Iminodiacetonitrile will release a lot of heat

at the same time

a large number of cold sources are needed to cool the product rapidly. At present

the heat released is not fully utilized

which leads to energy waste. Aim at the above problems

as an example of a domestic chemical enterprises

this study finds out the distance of the technology and energy consumption by means of the comparison of product output and energy consumption of Iminodiacetonitrile manufactured by nature gas between industry and international and the actual energy consumption

structure of consumption and energy flow by the actual consultation and calculation. According to the actual production system of the enterprise

the energy consumption and energy saving potential are analyzed and calculated

and the energy saving transformation scheme of the waste heat system is formulated. By using lithium bromide refrigerator instead of the original ammonia refrigerator

not only the reaction heat of the original venting is rationally used

but also a large amount of power consumption is saved.
