Compressor management facing severe challenges in China
Compressed air is an indispensable form of energy for iron and steel making enterprises and long-term operation of compressors consumes a massive amount of energy, which makes compressed air production very expensive.
How to effectively manage the compressed air system, adjust the pressure of the network according to production needs, or make the air compressor operate in an optimized state, and reduce the energy consumption of the air production, have become hot topics among technical personnel of energy departments in major steel mills in China.
Modernization of Yanshan Iron & Steel Co., Ltd.
Yanshan Iron & Steel Co., Ltd. (Yanshan Steel) is a steel mill under Hebei Iron and Steel Group which is one of the biggest Steel Groups in China. The company’s business scope is producing iron and steel, metallized pellet smelting, steel rolling, iron fine powder.
The first phase of energy-saving project at Yanshan Steel covered only one compressor station at No. 2 Steelmaking Plant. That compressor station has a total of 7 Hanwha centrifugal compressors with a total power of 8750 kW. All the centrifugal compressors are in the same network. Before using Sarlin Balance Smart Management System, steel mills often need to send people to observe the operation status of the compressor at the site. In addition, the air supply pressure in the compressed air system is unstable, which also causes more unnecessary energy consumption. This may also bring a lot of security risks in production.
In order to solve a series of problems in their compressed air system, energy department leaders at Yanshan Steel have been struggling to find a suitable solution. Coincidentally, they learned from Beijing JoinTeam International (JoinTeam), that Sarlin Balance Smart Management System is a thoroughly tested solutions for managing compressed air systems.
Sarlin has over 60 years history in compressed air system management with proven results. It is independently developed by Sarlin Oy Ab. It integrates design, update, and maintenance into a system for compressed air control and monitoring. It uses advanced technologies to control and manage centrifugal compressors. Sarin Balance Smart Management System can control the centrifugal compressor through controlling IGV, and reducing blow-off, thus achieving optimization and energy saving goals.
This project was promoted by the General Manager of Yanshan Steel, together with Mr. Shen, Director of the Energy Department, who was also responsible for the implementation of this project.
Sarlin’s Finnish experts went to the mill in Tangshan and discussed the whole project with relevant personnel from Yanshan Steel. From the project kick-off meeting to the equipment installation and final commissioning, Sarlin experts and representatives of JoinTeam were on site to ensure that every step of the project was carried out strictly according to the plan.
