Mostly Original
Process Flow Diagrams
Below
are many original process flow diagrams, all of which work and are
economically competitive.
If you have a concept
for a new process and need help filling in the details give us a call.
We can use our experience and vendor support to fill in the details on your
process flow diagram (PFD).
Of if you have a technical or chemical process problem, perhaps we can
suggest a flowsheet to meet your objectives. Developing a sound PFD is
the first step in evaluating the economic viability of your process.
Once a PFD is developed, a material and energy balance model can be
developed. Once this model is combined with project details and cost/price
information, we can develop an Income Statement for your process. From
here, we should be able to know if your process has a potential to be
competitive. Sorry, we don't know any short-cuts that are worth taking.
Below are a few of the none proprietary flow sheets we have developed over
the years. There are many more than now belong to existing companies
varying in size from mom-and-pop operations to major oil companies.

MgO and Ultra-Pure
Silica Production from
Asbestos Tailings
This flow sheets
demonstrate the production of magnesium from asbestos tailings using the
results of various research studies as my guide plus my own experience with
hydrometallurgical processing of magnesium. This flowsheet comes out
of a techno-economic model being developed to evaluate the economics of
making magnesium from asbestos via a unique carbo-thermal process.
The first flowsheet
of the process, making MgCl2 liquor from asbestos is
shown. Some optimization needs to occur here, but the flowsheet is
fundamentally sound:
Asbestos to MgCl2 Flowsheet2
The second flowsheet
precipitates the MgO.xH2O from the MgCl2 stream. The MgO.xH2O will be
converted to MgO at the front-end of the carbo-thermal process.
Flowsheet for MgCl2 to MgO.xH2O
The third flowsheet is a scrubbing
circuit from gases coming out the carbo-thermal process.
The process also produces ultrapure
silica, since asbestos tailings are naturally low in boron and phosphorus.
The process for making solar grade silicon is straight-forward starting with
a good quality silica.

Copper Removal
from Absorption Chillers
Air leaks into
vacuum absorption chillers causes copper to corrode and buildup in the
lithium bromide. It will eventually precipitate out somewhere in the
circuit, perhaps at a small opening, or you can actively remove it.

Nozzle-Based Carbothermal
Magnesium
NBC Mg
Process
The fourth flowsheet
is unique in that it puts three flow sheets together in a unique
configuration. All the sub-flowsheets have been tested at least at the
pilot-scale. It is my belief that a carbo-thermal process can compete
with the Chinese Industry, unless of course they adopt this process first.
The carbo-thermal process is based
on a "venturi" patent by MTL (Magnesium Technology Limited, Inc).
A paper is in progress that will be downloadable from here or TMS. The
MV_Model for this process is downloadable, see above. .
