The Zhenghe Petrochemical (Group) Co has obtained five national patents -- including one for a portable LPG gas-liquid connection tool -- from the State Intellectual Property Office, in the past four years, bringing its total number to 16. The company has increased its innovation efforts in technology and management through incentives and intellectual property rights protection. It’s easy to see that these patents improve the company’s competitiveness, overall strength, intellectual property, and intangible assets, and cut its income taxes.
The patents cover the portable LPG gas-liquid connection tool, as well as an air pre-heater that can reduce corrosion from dew, equipment that can reduce the COD in sewage and help use reclaimed water, equipment for reclaimed water use, and air-feeding equipment with temperature controls in aerobic sewage farm pools.
