Issue 25/2013 - Yanshan petrochemical benzene plant has record low energy consumption

The energy consumption of Yanshan petrochemical benzene production plant is record low

At present, the cumulative energy consumption of Yanshan petrochemical benzene production plant has been reduced by 60.
85 kg of standard oil / ton of benzene compared with the same period last year, which is the best level in history, effectively reducing the production cost of
the plant.

This year, the annual assessment index of energy consumption of benzene production plants issued by Yanshan Petrochemical is 6.
84%
lower than the new record in 2012.
In the face of challenges, cadres and employees develop ideas, take the initiative to attack, deeply tap the potential of the device to reduce consumption, and reduce the energy consumption of the device by strengthening daily energy-saving
management, optimizing the process operation of the device, hierarchical management of heat tracing, and strictly controlling the amount of circulating water.

The freezing point of the solvent used in the benzene making device is high, and it is easy to solidify when the outdoor temperature is lower than this temperature, so a long period of heat tracing is required for the solvent pipeline, generally from October of the current year to May of the following year
.
For other material lines in the benzene plant, less
heat is required.
In response to this situation, cadres and employees actively used their brains to think of countermeasures to achieve hierarchical management of pre-fractionation, hydrogenation system and extraction solvent heat tracing system to achieve the purpose of
reducing steam consumption.
