Where is it appropriate to send the process condensate from methanation units, and what impurities does it mainly contain?
Ammonia. Chloride ions. The process condensate is relatively clean. If the circulating water is from a closed-loop cooling tower, it can be used as make-up water for the closed-loop cooling tower.
Chloride ions are quite dangerous; their concentration should be very low. There shouldn’t be any powdery substances such as catalysts or ceramic balls present
The amount of chloride ions is low; no powdering has been observed for now
That’s great. I wonder how long it has been running? Has the ammonia content in the condensate been analyzed? What level can it be kept at in ppm?
Over a year. I haven’t checked the test results in a long time. So it’s unclear
A project I’m aware of uses the GPS gasification process; their methanation condensate is sent to the gasification unit as quench water
The water quality is good; it’s a bit of a waste to send it to gasification.

This water is used as supplementary water for the quenching water; the main source of the vaporized quenching water is still the black water produced by the black water treatment unit
