In adipic acid production, the nitric acid oxidation process generates large volumes of corrosive off-gases containing nitrogen oxides (NOx) that must be safely compressed and recovered. The Kenflo 2BW7 Liquid Ring Vacuum Pump Package, equipped with the CBA2 liquid ring compressor, is the ideal solution for this critical application.

Engineered as a closed-loop skid-mounted system specifically for chemical processes, the 2BW7 handles the compression and recovery of nitrosyl gases (NOx) in adipic acid plants.
Key advantages include: a closed-loop operating fluid system with an integrated heat exchanger that continuously cools and recycles the sealing liquid, significantly reducing operating costs; near-isothermal compression that keeps temperatures low, making it ideal for flammable, explosive, and corrosive gas services; corrosion-resistant flow components that withstand nitric acid attack; and full DCS compatibility for automated control.

Since Kenflo successfully developed the nitrosyl gas compressor for adipic acid projects in 2003, the 2BW7 package has become the industry standard in China, with its technical solution widely adopted as the template for new project bids.
