Social and economic benefits
Under normal operating pressure of the storage tank, the VOCs emission concentration range tested on site by the valve is between 1.61-15.2 mg/m3, which meets the special limit of 20 mg/m3 for VOCs unorganized emissions in the factory area as specified in Appendix A of the “Unorganized Emission Standards for Volatile Organic Compounds” (GB37822-2019), and has significant social benefits.
2. It can save VOCs collection and treatment facilities, while significantly reducing nitrogen consumption, bringing significant economic benefits to enterprises.
