OOPS Perhaps I should have used the term “thermal decomposition”. PHE have stated that the DMG process reduces carbon content recovered as biochar. Not clear on validity for specific feedstocks. Its potentially an additional revenue stream and If correct a soil amendment to improve soil fertility and seize carbon. They’ve got to get it right at both ends, I don't want toxic tatties.
What does our A.I. think about #PHE https://x.com/SwazersC/status/1788216801848967570
Pyrolysis is same as in DMG & involves heating to high temperature without oxygen.
It is not incineration. In incineration oxygen is present & there is CO2 emission.
I think EQT also uses the similar process.
I suppose our system is hidden under a blanket on the ship , don't want them chinese poking around looking at it you know what there like with them cameras .

Hi Silver,
In Powerhouses case, DMG stands for Distributed modular gasification, if that helps.
You sound like you come from an engineering/ Chemical engineering background, hopefully you'll know if there is any difference in the two processes. All I know is it has always been said that the DMG unit is not Pyrolysis.
ATB.
@Testpack - by DMG I'm guessing you are referring to Direct Melt Gasification? Nippon Steel have a VERY high temperature Direct Melt Gasification tech. Gasification is hotter than pyrolysis anyway, but Nippon Steel's DMG is 1,800*c which is potentially 300-600*c hotter than some gasification systems.
Essentially pyrolysis and gasification are very similar, the main difference is the level of oxygen in the process, in gasification (DMG or otherwise) it's very little, in pyrolysis it is Zero. Technically the first phase within a gasifier is pyrolysis, but then oxygen, air or steam are used a gasification agents.
Both processes create Syngas.
Gasification will create ash, Pyrolysis will create char. Pyrolysis char of plastic heavy waste is hazardous, and will most likely fail WACC (I've had a sample tested and was informed by Whiteness that they wouldn't even accept it into their Hazardous landfill).
DMG is not a Pyrolysis. Syngas is produced ( we have been led to believe ) in DMG, therefore a different method is at play. That method is extremely high heat, to form a plasma, in an oxygen free environment. This is why it is such a difficult process, and the main reason for delays. Perhaps Castlepaul, with his in depth knowledge of PHE can tell us why the Combustion Chamber ( kiln) has been mfd in China.? UK has a plethora of refractory manufacturers who make the linings for iron, steel, glass making furnaces.
Hi Divyup, happy to help. The 24-48 hour time was a reference to a specific piece of plant, not related to PHE in any way.
I was providing an example of how test and demonstration plants aren't as reliable a source of operation as a 3rd party commercial plant (the operator in my example only had this single plant, which they were using a sales tool trying to get a £multi million 50% deposit from prospective customers.
30silver: Thank you for your in-depth explanation of the syngas process with special regard too longevity of process, Down time/maintenance. I understand the temperatures within Town Gas kilns had an average life of 10 to 15 years before major refurbishment.
That said, I politely challenge the stated 24-28 hour cycle before shut down for maintenance. To clarify PHE cannot claim IP on pyrolysis but can and are with control systems, an essential part of the design maintaining efficiency and kiln longevity.
Thanks 30silver.
So the Holy Grail of all these systems is basically the same for everyone!
Extremely pernicerty and so finely balanced to be almost impossible to achieve.
So far….
As ever, we need a full scale operational system underway.
Good luck all.
35 days to go on the ship .
Gas cleaning system and the Gas analysing system being made for completion..
Protos news after our (FTU) has been completed , commissioned and fully banging out some good results,,, ledzep might give us a report before Christmas!!
Plenty of news a head .... bosh

@SteamingEagle - I'd not heard of Compact Syngas Solutions, however I do know some of their board from their previous positions, particularly the Commercial Director who I've done work with on ORC units for power production. He's also pushed another system, Pyrocore (well worth a look, it's good kit, just very expensive and very particular about feedstock).
The CEO is formerly of RefGas - another failed Gasification company, founded by his father, George and one that also claimed a patented process for gasification.
Downdraft gasifiers are great, as they do produce a lower tar gas (because the tars crack down through the oxidisation zone) and this is very useful where you are using biomass as a feedstock, as that will naturally produce more tars. The issue is when someone wants to put plastic containing waste into a downdraft gasifier, because the main drawback of downdraft gasifiers is ash bridging / clinker formation especially from low ash melt point materials such as, you guessed it - plastic.
One thing on their website set of a massive red flag - this quote:
"CSS’ innovative patented processes, enables us stand out from the competition, add to this our seven stages of syngas cleaning and cooling this ensures that our product gas is not just ultra clean but of the highest quality. In fact, the syngas produced by our system has been proven and accredited to be cleaner than natural gas, making it one of the purest fuels available for generating power."
The second half of that statement is patent BS - there is no way any syngas can possibly be "cleaner than natural gas" and most Syngas is completely unsuitable for use in an engine, many have tried, all have failed (when you're looking fro 8,000 hours per annum run time - not a demo plant that can run ok for 24-48 hours to show how great it is, only for the unit to be shut down the minute the clients leave the site, lest it burst into flames. Then starts a 3 week maintenance period before it's ready for another 2 day run.
Hopefully patent news soon !!
Hi Divviup, @ 16.55 Tuesday
And who are this crowd…” Compact Syngas Solutions” ?
Not in Stock market & no shares about.?
And they’ve got a compact system about to start producing syngas! ALREADY??!?
Where did they come from?
Are there other companies with similar systems ahead of PHE?
Are we about to become a non-starter or an ‘also ran’ outfit?
Has anybody questioned their patented system?
And where are PHE & EQT in the race?
A lot more questions in the pot….

Tyres are often the feedstock for those looking to use pyrolysis to create "carbon black" because it goes for something like £5,000 a tonne (not checked for a while) but the whole process ends up creating all sorts of other nasties, and I've seen half a dozes attempt, and fail. Tyre crumb can be re-used, but what I wouldn't be doing it trying to use it for fuel to create power - apart from anything else the CV is sky-high, which is bad if you're being paid gate fees to take it.
Grade C waste wood is filled with all sorts of horrible stuff, people seem to think it's clean biomass, but it's filled with all sorts of plastic coverings, rubber, nails, varnish, glue and who knows what else. I've seen Grade C waste wood analysis that came back as less than 60% biomass FFS.
Castle, you keep mentioning tyres, but they're already recycled and have been for years. Recycle and reuse (creating new products) is much better for the environment, saving the creation of more unnecessary plastic.
https://www.michelin.co.uk/auto/advice/change-tyres/car-tyre-recycling - a lot of invest from multi-billon pound companies already being spent on recycling tyres – none of them are working with PHE?
https://www.youtube.com/watch?v=8kfA9m0BbzI – probably a better way to recycle and reuse tyres!!
https://www.youtube.com/watch?v=9OB3x_cERyg – recycle and reuse – 10 tons per hour
Been on the booze Castle? 'if other pro PHE investors instead of talking s'hit actually top up'
Not sure what that means, but also not sure now is the best time to invest. Maybe that's why others aren't topping up?
I believe PHE shares will generate some good opportunities for short term profits off news, but I don't see it as a long term hold for me.
No competition for us , this is Exellent news for Ukraine.
Feedstock
Grade C Waste Wood
This material often comes from construction and demolition activates is regularly separated by waste recyclers as fuels for boilers, etc.
It's easy to use and no harm to the environment is wood .
The world's problem is untreatable plastic like old tyres and plastic dumping , our plastic goes to Indonesia and landfill ,,, creating problem..
The whole point is plastic cleaning the environment carbon neutral ..
+ GATE FEES ..Booom £

No mention of Plastic or tyre's, but Is this a concern?

Nice top up for me cheap as chips @.9p , if other pro PHE investors instead of talking s'hit actually top up ,,, LTH and patience...

Emissions? HVO / FAME will run way cleaner than Diesel, and could attract RTFC support and duty rebates to help save cost also. I need to look a lot more into this, plastics to Hydrogen I get, although I’m not au fait with the economics.
