Recovery of liquid nitrogen from tail gas washing in coal-based urea ammonia synthesis plants
Thread Content
Dear sea friends! Are there any ammonia plants that produce urea from coal, which recover argon from the liquid nitrogen wash exhaust gases? Our facility uses liquid nitrogen to treat 2,500 m3 of exhaust gas, and nearly 900 m3 of argon is generated per hour; we would like to recover this argon. What are the available processes for this, and what is the approximate investment cost? And how much is 1 cubic meter of argon at the moment?
There are specialized companies that produce equipment for argon recovery, using low-temperature distillation methods
