Spinning Disc Reactor – Nanoparticle Production Profit Potential

Review of Article: 20171106-infinity-turbine-sdr-spinning-disc-reactor-nanoparticles-sdr

 

Spinning Disc Reactors, or SDRs, are a very new type of processing unit that has had new applications discovered every year. All the articles used in this report are under 10 years old, with the newest one being published this year. This demonstrates how new SDRs are, especially in this field. While there is no publicly available information on using SDRs to make quantum dots, I believe that it is possible and most likely is being optimized currently in the private market.

A big field of interest as of lately has been process intensification which is a design approach that focuses on smaller, cleaner, safer, and more energy efficient processes. One design that has received considerable attention as of late has been the spinning disc reactor (SDR). Its basic design includes one or more liquid streams being flowed onto a quickly rotating disc.

The centrifugal acceleration from the rotation creates a very thin liquid film which significantly heightens the mass transfer and micro-mixing ability of the liquid streams. It also allows for more process control due to additional variables in the process including RPMs of the disc, the texture on the disc, the disc temperature, the injection site along the disc, disc size, pressure in the reactor, and environment in the reactor (can include speciality gas injection into reactor space). It also is a continuous feed reactor which can be applied to many processes that have relied on large volume and high residence time designs like batch or continuously stirred tank reactors (CSTR).

 

While the SDR can be used for many different processes, it excels greatly in a specific few. These include processes that rely on precipitation and uniformly mixed reactants. These traits allow for SDRs to be used in the “bottom-up” production of nanoparticles, where particles are created through nucleations and subsequently crystal growth. This is where batch reactors and CSTRs aren’t as easily applied due to their high volumes and lack of sufficient mixing ability. “Top-down” processing where bulk material is ground down into nanoparticles is typically avoided when trying to achieve nanoparticles of a certain size and narrow size distribution due to the lack of control over the process.

In 2010, the global market for quantum dots was low, sitting at $67 million [27]. It was projected to have an amazing 59.3% compound annual growth rate, which was mostly realized and by 2016 it has become a $610 million global market (with the estimated CAGR it was predicted to reach $670 million by 2015) [28]. The current growth rate is estimated at 41.3% now for 2016 to 2021, predicting the global market to reach $3.4 billion by 2021 [28].

Both silver and titanium dioxide nanoparticles have a realized and open market to enter with predicted growth and new applications coming out consistently. The cost to produce the materials is rather low and the production ability seems high enough, especially with silver, that a company could actively pursue using an SDR to produce the nanoparticles with success. Since the proof of concept and idea is already detailed, there would be a low cost of entry into these markets as well. The revenue from such could be used to support R&D into quantum dots or pharmaceutical nanoparticles.

Infinity Coil: Carbon-Based Energy Tube Graphene Energy Thread. Hemp Energy Tube. Bamboo Energy Cable.

PALO ALTO, Calif., Dec. 22, 2017 (NEWSWIRE) — Infinity Electrostatics LLC, a technology development firm for additive 3D printing, is pleased to announce a new energy storage device.

Infinity Coil Energy Tube:

Infinity is developing a unique continuous process to produce a continuous formed super-capacitor to store energy. The result of which can include a graphene energy thread, hemp energy tube, or bamboo energy cable. Names are interchangeable with materials depending on carbon sourced composition. Depending on thickness, they can be woven to form a moldable material.

Continuous Production Format:

The process involves roll forming so that a super capacitor may be assembled in a continuous format.

Deposition of fine particles may be done using electrostatics and a tribo-effect gun. Depending on output layered matrix, the result may be a thread, tube, or meso-scale pole. Flexibility is determined by the infrastructure infusion compound, which allows the final product to be thread, rope, or a structural panel. A continuous form loom can be used to incorporate multiple fiber types, including conductors and optical transmission fiber.

Hemp and Bamboo Based Carbon:

Typical carbon-based material is graphene. However, heat treated hemp and bamboo based carbon may also be used for a lower-cost production option.

Applications:

When the infrastructure (supporting) material  includes carbon fiber, hemp, or bamboo mat, resin or epoxy infused composites are continuously fed so that the layered material can be vacuum bagged into a solid structure. The result of which is a structure which becomes a super capacitor, or energy storage device. Using conventional carbon fiber lay-up methods, this energy storage structure could become a aircraft wing, car body, or a ship hull.

When supporting infrastructure material is combined with closed cell foam, or air, the unique insulating qualities of the structure allow it to be used to form flat, or shaped panels. Any insulated applications can now be used as a energy storage device. This would include installation for a wall in home or commercial building, roof, or even something as simple as a consumer beverage cooler.

In smaller applications, a tunable electrolyte can be used between layers, including CO2. The unique qualities of the supercritical energy dense molecule allow the carbon-based energy tube to be used in energy harvesting. Since CO2 can go supercritical at 31C, low-grade heat can now be used to produce electricity using the qualities of CO2 with tribo-effect.

If the tunable electrolyte is a carbon-based smart fluid, the structure can resemble a solid-state generator.

Summary: The Infinity Coil is a new energy storage device. Using graphene, eco-friendly hemp, or bamboo, almost any carbon based energy dense material can be used to make a super-capacitor or battery. With a tunable electrolyte, the energy storage device can resemble a solid state power generator. When combined into a structural panel, the device can be used as a aircraft wing, sides of a building, or hull of a ship. What is unique about this product is that it can be scaled up from a thin diameter thread woven into a rope or cable, which can be continuously formed into any shape panels. Using a 3-D printer, the structural applications could be infinite. Using renewable carbon based materials and components, the device is fully recyclable, and good for the environment.
