The compelling need to reduce CO2 emissions
has lead to many creative schemes to
accomplish CO2 emission reduction.
For economic or social reasons,
most are simply not feasible. However,
EnPro's CO2 emission reduction technology
is a monumental breakthrough, elegant
in its simplicity, effective in practice.
Unlike any other solution proposed thus far,
EnPro's process has some important benefits:
- Sequestration of CO2 emissions by over 95%.
- Non-ammonia process for production of
high quality 'green' soda ash (Na2CO3) –
a stable industrial raw material of commercial value;
low energy consumption –
current estimates indicate
energy consumption of less than half
that of the current processes for production of soda ash. - New low energy non-electrolysis process
for production of caustic soda (NaOH). - Technology is flexible enough
for the plant to produce either
soda ash or sodium hydroxide.
EnPro holds the exclusive global user rights
to proprietary CO2 emission reduction technology,
which is based on chemical reactions
used to consume CO2 from exhaust gases.
In general terms, the EnPro process
removes CO2 by chemically binding
it to the salt in seawater.
Valuable end-products such as
sodium carbonate (soda ash) and/or
sodium bicarbonate (baking soda)
are extracted from the process.
This is how it works:
- Salt water, together with salt,
goes into
the production of sodium hydroxide solution. - CO2 is sparged into the sodium hydroxide solution
in a so-called Carbonation module
where chemical reactions facilitate
a binding of the CO2 to the sodium in the solution. - This results in sodium carbonate,
which further processed into
sodium carbonate (soda ash). - The by-products are
hydrocloric acid and hypochlorite.
DETAILS
with the basic engineering assignment
for a soda ash manufacturing plant
to be located in Kollsnes, Norway.
Pöyry's scope of work includes basic engineering services
for the integral plant operations including
integration between individual process packages,
definitions of the required utilities and
the layout of these systems.
The project itself will utilise EnPro's technology,
developed in cooperation with
EnPro's technology cooperation partner
ENGSL Minerals DMCC,
to convert industrial CO2 emissions into valuable products,
such as
sodium carbonate ("soda ash") and sodium bicarbonate,
in an economical and environmentally friendly manner.
Carbon Capture and Utilisation
is a potentially vital 'tool in the box'
for helping to tackle climate change.
Soda ash production is normally associated with
large volumes of greenhouse gas emissions
as well as
significant energy consumption.
Using EnPro's technology will make it possible to
significantly reduce both and
has compelling Environmental Life Cycle results.
