Key innovations
The liquid nitrogen cryogenic VOC system achieves efficient recovery and emission standards; the nitrogen sealing system contaminates pollution and maintains pressure. Wastewater treatment technology optimizes treatment efficiency and costs through innovations such as pure oxygen aeration, reuse of ozone tail gas, and pH adjustment with carbon dioxide.
Potential economic benefits
VOC systems recycle valuable materials, reduce losses and protect equipment. Wastewater treatment technology reduces operating costs and stably meets standards.
Potential climate benefits
1. Liquid nitrogen cryogenic VOC system and nitrogen sealing system:
The cryogenic VOC system recycles materials and reduces new production emissions; the nitrogen sealing system prevents materials from volatilizing and reduces the carbon footprint.
2. Wastewater treatment technology:
Pure oxygen aeration improves efficiency and reduces energy consumption; ozone is reused to save electricity;CO2 pH adjustment replaces chemicals, all reducing energy consumption and carbon emissions.

Solution details
- Introduction of Liquid Nitrogen Cryogenic VOC System and Nitrogen Sealing System In the field of waste gas treatment, our products include Liquid Nitrogen Cryogenic VOC system devices and intelligent automatic nitrogen sealing system devices. Liquid nitrogen cryogenic VOC systems are widely used in chemical, pharmaceutical, chemical storage, oil and gas industries. The treated waste gas can not only meet increasingly stringent emission standards, but also recycle valuable materials. Intelligent automatic nitrogen sealing systems are widely used in storage tank materials. The automatic nitrogen seal prevents materials in the tank from entering the atmosphere and polluting the environment; it also isolates the atmosphere outside the tank to prevent impurities such as oxygen or moisture from mixing into the materials. At the same time, it balances the pressure in the storage tank and protects the equipment. 2. Wastewater treatment technology Under the dual challenges of strict sewage discharge standards and reasonable treatment costs, Praxair provides a series of wastewater treatment technology combinations tailored to optimize the operation of sewage plants, which can simultaneously meet stable compliance, reasonable operating costs, innovation and safety.
