Hello thzorro, actually there is also a need for liquid AD plants. But if you got biomass with high dry matter, 20% or higher, e.g. municipal biowaste, greencut, straw, food waste, solid animal manure, etc. you should definitely consider choosing a dry AD plant (SSAD). You will get fewer, mostly expensive, technical issues and maintenance, save huge effort in substrate handling and preprocessing etc. Also, dry AD is by far not as water-consuming as common liquid digesters, therefore suitable for dry regions around the world. Have a nice day! #TeamRenergon
yeah in my system i need a way to process waste but also convert it into safe nutrients for soil, and potentially other users as well. humans tend have more ammonia in their pee and poop, and it's usually the aerobic bacteria that convert ammonia into h2 and n2 gas, while the anaerobic methanogenic bacteria produce methane which is a fuel more suitable for fuel, heating and is almost a drop in replacement for gasoline vehicles, all it takes is to reprogram the ECU computers of cars, and pedal to gas regulation ofc. similar to adding NO2, systems. and purchase natural gas appliances to utilize it. with that in mind we can also use the process that renergon uses to seed a liquid fermenter after pastuerization of the digestate along with table scraps, and if necessary test for coliform bacteria content and if not at an acceptable level, pasteurize the slurry, and use it for compost. pasturization can be done with other renewables, but post/pre pastuerization i'm not sure which is safer/more economical.
Great video and wonderful company. I’m curious, how you acquire the gaseous nitrogen?-Fractional distillation? Just curious how sustainable and eco-friendly the whole process is, including the precursors and heavy equipment. Do the plant tractors/machinery use the biogas to operate, as well? Thank you.
I think heavy machinery will be one of the last parts of the economy to go renewable, so probably not But keep in mind that fossil fuel plants use heavy machinery that also runs on fossil fuel. That aspect is the same. But biomass/gas plants don't burn fossil fuels directly
it's fairly simple to convert gasoline engines to natural gas engines, even the simplest conversion of putting a CNG tank with your pedal attached to a gas flow regulator would work better than ethanol in theory. the ideal A/F ratio for natural gas is around 17.something:1 compared to 14.7:1 in most gasoline engines. ethanol as a much lower a/f ratio than gas or methane, which results in lower fuel economy as the mixture is too rich, with pure methane, you need a leaner mixture for optimum performance, but since it's close you could run your car on methane without adjusting the ECU. you'll get bad fuel economy, but it will work. adjust the ECU and i would probably work slightly worse than a gasoline engine. most light work machinery uses propane gas, and if a company is really committed, they could use LNG or CNG work machines, or simply use methane generators to power hydraulic motors for actual work. in reality work machines are a drop in the bucket for emissions.
ammonia. humans have a lot of ammonia in their waste, aerobes can turn ammonia into nitrates and nitrites, which if left to continue to digest will turn into n2 and h2 gasses. nitrates are what plants love. combine this with your standard compost and you'll should have a fairly nice mixture.
nice! wondering why still building mostly liquid digesters? because evryone got used to it? ok, no idea...

@@Meleeman011 hello, can I please have your email to discuss?
Yes, of course: info@renergon.com
Although the name doesn't changes, the biogas is more natural than the same natural gas.
Nice video! Thanks

They might be using pressure swing absorption since it’s a little less complex then distillation

wondering where Nitrogen is coming from ....

This is good as long as it doesn't expand CAFOs which it is doing.
nice!
thanks!
