PyroGenesis Inc T.PYR

Alternate Symbol(s):  PYRGF

PyroGenesis Inc., formerly PyroGenesis Canada Inc., is a Canada-based high-tech company. The Company is engaged in the design, development, manufacture and commercialization of advanced plasma processes and sustainable solutions which reduce greenhouse gases (GHG). The Company has created proprietary, patented and advanced plasma technologies that are used in four markets: iron ore palletization, aluminum, waste management, and additive manufacturing. It provides engineering and manufacturing expertise, contract research, as well as turnkey process equipment packages to the defense, metallurgical, mining, additive manufacturing (including 3D printing), oil and gas, and environmental industries. Its products and services include plasma atomized metal powders, aluminum and zinc dross recovery, waste management, plasma torches, and innovation/custom process development. It offers PUREVAP, which is a high purity metallurgical grade silicon and solar grade silicon from quartz.

RE:RE:Pyro Plasma Torch

RE:RE:Pyro Plasma TorchI couldn't have said it better!

I would add a few things:

1- Plasma torches operate at high voltage near high pressure water cooling and require compressed gas. This increases the cost of installation and operation, compared to gas burners.

2- The powers available per unit are limited to approximately 4 MW per torch. (PYR one at 1 MW according to their specifications).

3- The limited lifetime of the electrodes remains a major drawback, making their use in continuous operation particularly tricky.

4- The gas jets of plasma torches operate at a much higher temperature than conventional gas burners. This can be advantageous for special applications, such as incinerations. For more conventional metallurgical uses, these elevated temperatures must be accommodated by process modifications.

5- The formation of NOx, associated with air or nitrogen plasma must be taken into account and avoided. NOx being 300 times more harmful to the environment than CO2.

CONCL: Plasma torches have their uses in certain applications. But they are not the panacea that some would attribute to them.

Good Moning

You are assuming that the electricity to power the torches is green . Hydrocarbons are still used to generate  aprox 60 % of the worlds electricity.

Examples 

Hydrocarbon  use for generation .  Canada 18%    Brazil 20%  United States 60% Australia 80%   China 70 % Germany 70% or more and coal climbing  All the countries listed use coal which is double the emissions of natural gas

Until the countries run 100% renewable and have excess power it is a false economy to claim that the torches are green.   They are as dirty as the dirtiest fuels burned in the generating stations  supplyng the grid and may be worse with losses in generation and transmission.

Even if torches  are directly tied to a hydro dam or solar  the power taken to keep the lights on in the the rest of the country is shifted to the gas or coal fed portion of the grid . Brazil for example continues to build new gas plants and still burns coal.  

Until a country is 100% clean energy in the grid the massive load of the torches is as dirty as the dirtiest coal or gas powering the grids.  As plasma is 15% less efficient , not including additional line loss of aprox 5%   then Natural gas the torches are dirtier and cause more CO2 emmisions than burning gas directly in the torches and if the grid still uses coal anywhere  than the torches are dirtier than coal. 

An even more shocking calculation may be that the newest  Natural Gas power plants are under 60 % thermal efficiency while coal is 37 % thermal efficiency  and this has to be a substantial factor when comparing the "whole picture" 

 In theory the burning of Natural gas directly in  torches may be 50 % LESS CO2 than Plasma torches in a partially gas fired grid   and since coal is double gas for CO2 the final  answer could be shocking . In addition Plasma causes NOx which contributes to acid rain,

I of course would welcome a more  accurate  analysis by Pyrogenesis engineers as I may be missing factors and rounded . Again I would think they would have studied this and should be readily  available.

IMHO this is  Robbing Peter to pay Paul and might be paying with a " tax"

 And again I am and have never directly or indirectly held a short position in HPQ or PYR

Some of you claim that Natural Gas is the cleanest and will be used by Vale.  Just ask your self the question, Natural Gas in not a new energy source.  Why do you think Vale and Rio purchasing Plasma Torch from Pyro.

Natural Gas is mostly methaine and cause GHG.  This is temperory solution.
 
Plasma Torch is the future.  Using electricity is the most economical and cleanest solution for the Iron Ore Industries.

Electricity produced from Nuclear, solar and wind or even bio-gas.
