On a late-summer afternoon, good news arrived near the newly constructed circulating water pool at Noah Company: the newly installed 6000m ³ /h The circulating water pump successfully completed its trial run, with all parameters remaining stable and meeting the required standards! This months-long energy-saving renovation project has finally come to a successful conclusion, thanks to the collaborative efforts of multiple departments working together to overcome challenges.

The aging system "consumes high energy" and has become a development bottleneck.

As the new equipment is gradually put into operation, the existing circulating water system has increasingly revealed issues such as supply-demand imbalances and excessively high energy consumption. Meanwhile, the water flow on the north side is sluggish, while the return water pressure on the south side has surged to dangerously high levels. 0.5MPa A significant amount of electrical energy is wasted due to valve throttling. Energy audits reveal that the system consumes more than half of the plant's total electricity, significantly higher than that of companies of similar scale. 20%-30% 。

Precise Strategies: Replacing Dual Pumps with a Single Pump to Reduce Consumption and Enhance Efficiency

This year 3 This month, the company launched a transformation centered around "reducing head pressure, adjusting flow rate, and improving efficiency." After conducting on-site surveys and multiple rounds of data verification, the team ultimately decided to adopt a single unit. 6000m ³ /h、45 Mi Yangcheng's new pump replaces the original two high-head water pumps, reducing energy consumption at the source.

Overcoming Challenges and Difficulties: 42 Achieve "Impossible" Construction in Record Time

The project faces challenges such as tight deadlines and reversed construction sequences. The team addressed these issues by building a new pit and water absorption pool, as well as optimizing the installation process. 42 Complete civil construction, equipment installation, and pipeline connections within the specified timeframe. Throughout the construction period, all disciplines worked closely together, working around the clock to expedite progress and secure valuable time for subsequent commissioning.

Significant Benefits: Energy Savings 314 Wandu, Stability Enhanced

After the new pump was put into operation, the operating power was only 889kW , which is lower than the original system 370kW , Save electricity during holidays 314.5 Wandu, saving electricity costs by over 270 Ten thousand yuan. Meanwhile, the water supply pressure across the entire plant has become more balanced, significantly enhancing system stability and laying a solid foundation for advancing intelligent control in the future.

Stepping Toward a New Starting Point for Green Transformation

This renovation not only solved the longstanding issue of the old system operating under strain, but also effectively demonstrated the deep integration of energy conservation, consumption reduction, and high-quality development. Nuo'ao Company has taken concrete actions, paving the way for a practical approach to green upgrades in the chemical industry.
