Retrofit Engineering

CGEC is committed to the research and development, promotion, and application of environmental protection products and technology. CGEC gives full play to advantages of rubber tire industry and management, technology, and talent. Use of advanced technology of environmental emission and control and operation management proposals provide emission reducing and energy saving technology consulting, proposal design, construction, operation management, and other services.
 
Non-power central condensate recovery system
Our latest technology of condensate recovery is based on the new concept and the steam trap will be replaced by it.
The system is a closed system and no steam discharges from it. The energy saving rate is more than 20%
System has long service life and is maintenance-free
The condensate returns back to the boiler room by gravity only
The new condensate recovery system is running automatically

 
Rubber plant gas treatment
Exhaust gas from mixing and curing is treated by various combination processes such as mini-hydrocyclone oil removing, low temperature plasma catalysis, photoelectron-oxidation catalysis, and adsorption filtration.
The odor removal rate is more than 80% and NMHC more than 85%; the working environment is greatly improved.
No secondary pollution

 
Sewage recycling
We adopt the traditional biological treatment and the new membrane filtration technology in the sewage recycling.
The sewage could be reused as living water, cooling water, and boiler water after the treatment
Sewage recycling possesses both good social efficiency and economic benefits due to its low running cost.

 

Power from pressure and heat recovery- screw expander technique
•Steam reducing valve will be replaced by the screw expander which has the function of generating power by different steam pressure.Then the most of waste energy will be recovered.
The screw expander has the powerful adaptability for fluids such as superheated steam, saturated steam, and so on. It also has strong adaptability for the off design condition.
No need for turning or on duty; no major repairs within 10 years.


 
Air compression energy saving technology
The technology includes grading supply of compressed air, the expert control system of air compressor, a close track of system pressure, and so on.
The system has a number of patents.
 
Desalination
•Two main desalination technolgies:SWRO & MED.
Our Saudi Aramco project is the first desalination project undertaken by a China State-Owned Company.
