New Technology Reduces Emissions at Chenhong Paint Factory

NEWS RELEASE (San Diego, CA) Steps to improve air quality at the Chenhong Paint factories has been successfully completed and verified by authorities, according to leadership in China. In early 2017, Chenhong paint installed $3 million in new equipment, which has been verified by authorities and put into operation.

The VOC (volatile organic compounds) processing equipment is designed to remove exhaust gas and dust emissions using a molecular sieve fluidized bed based absorption and concentration plus catalytic oxidation with a throughput of 4000m³/h.

For some background on this process, during production of solvent based paint, exhaust gases such as NMCH, benzene, toluene, xylene may be discharged. Since the installation of this new Chenhong equipment, these harmful gas residues will be collected by terminal devices and then absorbed and concentrated through the molecular sieve fluidized bed. With the absorption of the molecular sieve, the harmful components in the exhaust gases are intercepted, leaving only clean gases for output. After saturation, the molecular sieve is desorbed. The removed organic exhausts are sent to the catalytic combustion units through a small-volume high-density filter and converted to carbon dioxide and water by catalytic oxidation. The byproduct gases reach below the acceptable discharge standards.

Since the equipment has been placed into operation, odors inside the factory are greatly reduced. At the same time, harmful gas and dust pollution has also been significantly reduced which has been confirmed by high tech detection equipment. The emission concentration of benzene is 3.53 mg/m³, toluene is 6.99 mg/m³ and xylene is 19.97 mg/m³. These are considerably below than the national standards, which are 4 mg/m³, 30 mg/m³ and 30 mg/m³. (See Chart below: Emission concentration at Chenhong Paint Co. is Cleaner)
