Energos, AlterNRG, Westinghouse, TPA Plasma, PEAT International, etc. The list goes on. All have systems in operation and beat PHE to it.

How are they going to afford to build a £10m plant linked to a fuel cell ?

Westinghouse already have a plasma gasification system that runs at 3000 degrees Centigrade and can processs 330,000 tonnes per year, i.e. 904 tonnes per day, which 36 times more than PHE's planned still in design largest 25 tonne per day system.



So Westinghouse have already beaten PHE to it and have a system that offers higher temperatures and better economy of scale.

"Sophisticated plasma torches generate super-high heat (+3,000° C) to change solid waste into synthetic gas, or syngas."

"Westinghouse Plasma gasifiers can process up to 330,000 tonnes per year of waste material, producing syngas of up to 3.5 Million Btu per year."

Infact I believe Westinghouse have already taken the Asian market PHE were hoping to get.

What a shame for all these negative doubters Wow they are going to miss a ride !!

Companies promoting plasma arc, gasification and pyrolysis all claim the technology is not an incinerator. While there are differences with traditional incineration technologies, the plasma arc, gasification and pyrolysis processes all involve incineration/combustion as an essential component.
All of these technologies emit dioxins and other harmful pollutants, and are defined as incineration by the U.S. Environmental Protection Agency (U.S. Environmental Protection Agency, Title 40: Protection of Environment, Hazardous Waste Management System: General, subpart B—definitions, 260.10, current as of February 5, 2008).
If you relied on the websites of the companies, their diagrams made public to date and process descriptions, you probably would not realize that these are indeed incinerators disguised as “renewable energy” technologies.

Not the same technology deccer1 as you well know Companies promoting plasma arc, gasification and pyrolysis all claim the technology is not an incinerator.

How many industrial places want to store waste on their site or would prefer it to be taken away?

The calculations published this week assume 8,000 hours per year of usage. But what happens when the factory has seasonal downs and isn't producing at least 25tpd of viable waste? That will impact on the payback and return for any Unit.

1. Your suggestion that "Transporting so much rubbish to one big plant is not as efficient and has a much bigger carbon footprint" is utter nonsense. You wait until you have enough waste to transport and then transport it in your zero carbon electic or fuel cell lorry. A bigger plant will also charge you less to dispose of your rubbish than a smaller plant because bigger plants have economy of scale and better margins.

2. Westinghuse can make smaller plasma gasification plants in direct competition to PHE - note the words "up to".

"Westinghouse Plasma gasifiers can process up to 330,000 tonnes per year of waste material, producing syngas of up to 3.5 Million Btu per year."

3. If PHE are not going to be competing with the big plants, as you confirm, it is probably because they CANNOT compete with the big plants, and will only ever be small players.

Transporting so much rubbish to one big plant is not as efficient and has a much bigger carbon footprint We are not competing with the big 100,000 ton a year plants !!I got my information from the company and you lucky Jim don't work for the company so who should we believe ???

Getting there slowly .

Warwick 69, I don't know you and you do not know anything about me. You seem such a nasty person. It maybe that you are just that way, or you are an agent of PHE. It seems like the latter. The information you have received is wrong, but if I explained it fully, you would still not believe it, because you seem to be like all the others refusing to face up to reality. Believe me, someday you will have to.

Containing 2000 degrees centigrade

It's interesting that the Plasma Power process separates the two parts of the process - the initial waste processing, which contains oxygen, operates at 800C, and the subsequent oxygen-free processing of the syngas takes place at the fantastic temperature of 8,000C.

-------

'The core of the Gasplasma® process comprises a gasifier (preferably a fluidised bed gasifier) which transforms the organic material in the RDF into a crude syngas containing tars and chars. It does this by heating the RDF to a high temperature, around 800°C, in a highly controlled reduced oxygen environment. The fluidised bed gasifier allows for the production of a consistent syngas and achieves high conversion efficiencies.

'The crude syngas exiting the gasifier is then passed into the separate, secondary Gasplasma® plasma conversion unit. The intense heat from the plasma arc – in excess of 8,000°C – and the strong ultraviolet light of the plasma result in the complete cracking of tar substances and the breakdown of char materials. The cracking creates a clean syngas, whilst the inorganic elements in the ash carried over from the gasifier are vitrified into a product called Plasmarok®.'

Hi Beeezzz, Over the many years of developing the Pyromex technology it was tested at various temperatures upto 3000c, but 1500c is a good working tempreture as all waste will gasify at 1500c. It was run continuously for the maximum of 10 hours at various times. A large range of different materials were used including ceramics to try and solve the problem or rather to find an acceptable balance in which the theory of the technology could be developed in such a way to make the technology a commercial reality. The problem being that reactor core destroys itself throughout the operation. Finding a material that can give a balance to make the technology commercially viable is the goal. Having said that the major problem as I have said before is the oxygen in the waste being gasified, as an oxygen free atmosphere has to be maintained at all times otherwise at 1500c a dangerous situation could occur. I personally feel that the balance needed for this technology to progress is unattainable. I think jaknife puts it overall quite well. For PHE it is a dream to come true, but the directors must know it will never be achieved, as they must know the downside but only want to listen to the upside. It is like a drug, once you are hooked, for various reasons you cannot walk away. However in this case, innocent people get hurt.

Silence about UKOG ????

Tick tock tick tock....said the CTAG clock.
You must have subliminally remembered this when you posted tick tick tick this week.

[dolphin158] 29/7/2017 06:16

Oh Mr big company you have copied our technology, boo boo.

It isn't your technology as there is no patent.

We are bigger than you, we are richer than you, we have more marketing clout. Buyers particularly in the public sector prefer to buy from established big and financially strong busineess as there is less chance of being sacked if it goes wrong.

Will the copiers in China fuss about your technology if it worked and better still wasn't patented ? No9, thank you you very much from the Chinese takeaway!

[dolphin158] 29/7/2017 06:08

Ohhcj hit a raw nerve there.

Must remember not to mention CTAG.

What has happened to UKOG the company being heavily mentioned by you earlier this week as what will happen to PHE's share price?

Why no mention in the last two days? Is it due to the share price collapsing just as quick???
