Regarding the conversion rate of David methanation
Thread Content
Who knows the primary conversion and total conversion of each methanation converter in David? Upon checking available information, only the volume fraction of CH4 in product SNG is provided, which seems to be around 92%; however, the primary conversion rates for each column cannot be found. What is the recycle ratio for the large number of methane chemical processing units? Some sources indicate around 60%, while others suggest around 40%. I would appreciate some expert guidance on this.
Ask David the patent holder; if you want to see it in person, you can conduct a review of the existing devices
