Solution details

(1) Technical scope of application

(1) Technical scope of application

This technology is mainly used for energy-saving technology in motors in various industries.

(2) Technical principles (transformation content)

① Technical introduction

Change the appropriate motor to reduce energy consumption by accounting for deviations between design capabilities and actual operability requirements.

② Energy saving principles

Before the renovation, the air compressor was driven by a 500kW motor, and the shaft power was 459kW, which exceeded the actual process requirements. The project reduced the shaft power to 387kW by changing the compressor assembly, and the transmission capacity matched the actual demand, saving transportation power consumption. The project is to change the appropriate motor to reduce energy consumption by calculating the deviation between design capabilities and actual operability requirements.

(3) Application cases

Covestro Polymers (China) Co., Ltd. Atlas Centrifuge optimizes energy-saving technical transformation project.

1) Implementation content and cycle: Before the transformation, the air compressor was driven by a 500kW motor, and the shaft power was 459kW, which exceeded the actual process requirements. The project reduced the shaft power to 387kW by changing the compressor assembly, and the transmission capacity matched the actual demand, saving transportation power consumption.

The implementation cycle is 9 months.

2) Energy conservation and emission reduction effect and investment payback period:

Project power saving =(0.0850kWh/m3-0.0732kWh/m3)*48350949m3= 571,000 kWh

Converted to standard coal = 571,000 kWh*2.88tce/10,000 kWh=164.4tce

The payback period is 0.49 years.

(4) Potential for replication and promotion, energy-saving potential (payback period)

The technology is applied to all walks of life, used for energy-saving technical transformation, the technical transformation method is safe and reliable, can effectively improve the original defects of the existing motor, has greater energy-saving potential, obvious energy-saving emission reduction effect, broad application prospect and greater replication potential.
