EMC energy-U-AIR CHAIN Energy Saving ecological Technology (Jiangsu) Co. LTD

Gas supply service mode (BOT)

In the compressed air field, based on the BOT mode of lean management, the energy company implements all-round operation hosting services for the user's compressed air system, and undertakes all-round services such as investment, construction, operation and maintenance of the user's compressed air system,

While reducing the user's gas consumption cost, continue to carry out energy-saving upgrading to recover the project investment and reasonable profits. After the expiration of the contract, the assets of the air compressor station will be handed over to the customer free of charge

Gas demand 100 m ³/ Min, pressure demand 7 bar, gas quality demand, dew point 2-10 degrees

According to the current comprehensive gas consumption cost of 0.1 yuan / M ³， The startup time is 8000h, the electricity price is 0.7 yuan / kWh, and the total annual expenditure is 4.8 million yuan

The gas supply service (BOT) mode is adopted, and our company invests, constructs and undertakes the electricity charge and operation management. The comprehensive gas quotation decreases by 5% - 10%, saving 480000 yuan per year

After the end of the contract, the property right of the equipment will be handed over to the user, and our company will ensure that the gas cost will be reduced by 5% - 10%

Energy saving concept

03
Gas side
According to different process requirements, supply by quality and pressure, adopt terminal energy-saving management means, process upgrading and transformation, use of energy-saving nozzle, application of throttling technology and application of pressure reduction technology
04
lean management
Data collection and platform analysis are carried out in the whole process to realize intelligent and intelligent operation. Online and offline are combined to reduce the comprehensive gas consumption cost through lean management

Lean management services

Provide compressed air system energy audit, energy-saving diagnosis, energy efficiency monitoring, smart cloud platform installation and other services. Conduct professional analysis on the energy efficiency, pipe network pressure loss and gas quality of the customer's compressed air system, and evaluate the energy consumption of the system through quantitative data
On the basis of accurate evaluation, according to the characteristics and requirements of gas consumption in the customer's production process, gas consumption fluctuation law and gas quality requirements, carry out the overall design of the compressed air system, including air compression station building, gas supply / pressure regulating equipment, purification / gas storage equipment, transmission pipe network, gas consumption terminal, etc., and establish the energy efficiency standard of the compressed air system
The project customized the production of high-efficiency air compressors, cold dryers and suction dryers to ensure no significant reduction in equipment energy efficiency, no overhaul and no replacement of main components during the project cycle, so as to achieve energy conservation and consumption reduction of the whole compressed air system and increase efficiency and reduce cost for customers
Precision production operation and maintenance is our energy-saving operation and maintenance management concept. With the industrial Internet of things as the tool, through the smart cloud platform of excellent gas reservoir, we can realize the full life cycle service of compressed air, and continuously tap the energy-saving potential in the three energy consumption systems of gas, water and electricity, and the four system links of production, purification, transmission and process end use

administration cost
Accounting for 2% (management personnel, daily management expenses, etc.)
Capital cost
Accounting for 3% (the capital cost of air compressor station construction is calculated at 8%)

Case sharing

Steel industry

The original air compressor station of a stainless steel enterprise has a total of 60m ³/ Min screw air compressor 7 sets. The project adopts energy-saving sharing (EMC) mode of cooperation, and the contract period is six years. In April 2019, excellent gas storage energy conservation signed an EMC contract with the enterprise. As one of the largest stainless steel manufacturers in China, due to industrial application factors, compressed air energy consumption accounts for a large production cost. Through the implementation of energy trusteeship project, the comprehensive cost of compressed air is reduced by 26% on the basis of the same gas consumption; Good economic and social benefits have been achieved.
