Since the beginning of this year, Shijiazhuang Refinery has deeply tapped the potential of reducing the consumption of steam, circulating water and nitrogen, and achieved a reduction in the comprehensive energy consumption of polypropylene units
.

The power consumption is the largest in the comprehensive energy consumption of the device, and the equipment extrusion granulator is the largest power consumption
.
They adjust the product structure to produce more high melt index products and reduce the power consumption of the extrusion granulator
.
Starting from daily operation, tap the potential of steam consumption reduction, adjust the steam consumption according to the production load, not only meet the needs of use, but also achieve energy saving, and reduce the steam consumption caused by the start and stop of the extrusion granulator
.
Implement fine management, adjust valves in time, and reduce circulating water consumption on the premise of ensuring that the flow rate meets equipment requirements
.
Strengthen on-site inspections, adjust the amount of nitrogen in the rotary valve and the amount of purge nitrogen, and strive to reduce nitrogen consumption
