Find answers to your questions:
1. Does your tire pyrolysis facility maintain a vacuum
inside the reactor?
No. Our advanced and proven technology does not require a vacuum inside the reactor.
2. How will the reactor remain in an oxygen free state
during normal production operation?
First, when preparing for production operation, we purge the reactor and piping
of oxygen by pre-charging the system using nitrogen (N2). Second, once the reactor
has reached operational temperature, the tire shreds are fed into the reactor. The
feeding system progressively heats the tire shreds. As the shreds get hotter, they
also get softer and then they compress forming themselves into a homogeneous mass
with all the air (O2) removed. Third, as the tire shreds enter the pyrolytic area
of the reactor, with all the air removed, our patent pending reactor seal keeps
any air from seeping in. You can compare the tire shreds as being squeezed into
the pyrolytic area of the reactor, similar to squeezing toothpaste out of a tube
of toothpaste, an extruder type action. The seal effect will remain secure even
if the process is stopped, power is lost, etc.
3. Does the facility need BACT (Best Available Control
Technology)?
No. Our facility is designed for zero emissions, to be “green” and completely environmentally
friendly.
4. How is oxygen prevented from entering the duct work?
We use quality stainless steel piping, making the system air tight and not subject
to corrosion.
5. What are the specifications on the scrubbers and
what temperatures do they operate at?
The following pages detail the size and specifications of our Gas Clarification
(Section C) and Exhaust Scrubbing Systems (Section D). Both of these systems operate
at ambient temperatures. The bi-products that enter both of these systems are also
at ambient temperature, well below the temperatures that might produce harmful products.
6. Are there temperature variations inside the pyrolysis
reactor?
If any, they are completely negligible (+/- 1 ºC). Our patent pending pyrolytic
reactor uses a type of heating chamber that wraps the reactor so as to maintain
a constant and consistent temperature throughout. The reactor is approx. 1.3m (4.3
feet) in diameter and rotating, further reducing temperature variations.
7. Is this an electric heating system?
No. We use a patent pending heating solution, for more of a boiler type heating
method. The MSD for the heating solution is supplied in this booklet in Section
5.2. The solution enables the reactor to be gradually heated during initial startups
avoiding thermal shock to the system. In the event of a power outage, the heating
solution is returned by gravity to the heating solution storage tank (B18). We have
layers of insulation to effectively eliminate heat loss and enable maximum heat
transfer to the pyrolysis chamber. The reactor slowly rotates, approx. 2 minutes
per revolution, so further allowing the heat to be equally distributed.
8. Can the operating conditions of the system be monitored?
Yes and we do so. Our standard system is equipment with a CCTV monitoring system
as well as temperature and pressure gauges.
9. Does your system apply a catalyst to the tire shreds?
Yes. We supply a patent pending catalyst. The MSD for the catalyst is provided in
Section 5.1 of this manual. The catalyst improves the pyrolytic process and optimizes
the output of the reactor.
10. Why have other tire pyrolysis facilities quickly
shutdown ?
We have found that many of the facilities that have shutdown were of an older design
and technology, using high temperatures and applying direct heat to melt the tires.
Applying direct heat to melt the tires leads to much higher maintenance and operational
costs, as well as shortening the life span of the equipment. Many facilities also
produced substantial amounts of waste products that they had to pay to dispose of.
The older facilities also produced a poor quality carbon black, less fuel oil and
higher amounts of gas that could only be compressed into liquid. The older facilities
were unfriendly to the environment with overall safety lower. Our advanced technology
uses lower heat, approx. 450 ºC (842 ºF) and we build a facility that does not regularly
generate waste. Using the lower temperatures greatly reduces the thermal shock to
the equipment which extends the equipments’ life span. We produce a high quality
carbon black and have a high output of fuel oil. Our facility is friendly to the
environment and much safer.
11. What are the safeguards in case of overpressure
in the reactor?
The reactor operates at near zero pressure. For further safety, we have three pressure
relief valves on the reactor. If an overpressure situation should occur, the pressure
relief valve(s) will open to immediately stop the overpressure situation.
12. Is this an electric heating system?
No. We use a patent pending heating solution, for more of a boiler type heating
method. The MSD for the heating solution is supplied in this booklet in Section
5.2. The solution enables the reactor to be gradually heated during initial startups
avoiding thermal shock to the system. In the event of a power outage, the heating
solution is returned by gravity to the heating solution storage tank (B18). We have
layers of insulation to effectively eliminate heat loss and enable maximum heat
transfer to the pyrolysis chamber. The reactor slowly rotates, approx. 2 minutes
per revolution, so further allowing the heat to be equally distributed.
13. If the pressure relief valves open to vent the
overpressure, will there be gases released into the air?
No. We have piped the relief valves to our scrubbers to assure that the gases released
will be scrubbed, so as not to harm the environment. Refer to the next page, with
the one-line drawing, showing how we safely control such a situation.
14. What if all the electric power goes off, will gas
be released into the air?
No. Our system does not release any harmful items during a loss of power. Even if
the reactor is full of tires, the reactor stops rotating but our patent pending
sealing system assures that everything inside the reactor remains inside the sealed
reactor. Once the electrical power has been restored, the reactor heating system
will apply heat to the tire shreds and once operating temperature has been established,
the facility can return to full operation.
15. What are the safeguards in case of overpressure
in the reactor?
The reactor operates at near zero pressure. For further safety, we have three pressure
relief valves on the reactor. If an overpressure situation should occur, the pressure
relief valve(s) will open to immediately stop the overpressure situation.
16. Is there an actual facility in operation that can
be referenced ?
Yes. We have supplied several facilities which are in operation in Malaysia, Taiwan
and China. We also have orders pending for other countries. We have a “showroom”
available for reference near our home office in Jinan, China. The showroom is a
fully operational pyrolysis facility. We built the showroom so as to continue our
research and improvements to our equipment.
17. Do you have additional information of your Plastic
Pyrolysis Process?
Yes. As this is a somewhat new product offering, the information is being gathered
and will be available as soon as possible. We will continue to update the FAQs as
we collect the information, please be patient. Once the electrical power has been
restored, the reactor heating system will apply heat to the tire shreds and once
operating temperature has been established, the facility can return to full operation.
18. What is the size and capacity of the existing operations?
We have systems in operation of 10,000 metric tons per year.
19. Is there an actual Plastic Pyrolysis facility in
operation that can be referenced ?
Yes, but we do not own the facility(ies) and must receive permission from our customer
before any visit(s) can be made. We respect and protect our customers' privacy and
each request may or may not be granted. For a short time we had a Plastic Pyrolysis
operating in our showroom but that system has been dismantled and is no longer there.
20. Do you anticipate the equipment to take mixed plastics?
Yes, our Plastic Pyrolysis systems can take mixed plastics, but only 5% PVC.
20. What percent non-plastic do you think the equipment
can tolerate?
Our Plastic Pyrolysis systems can take “everything” but will reduce the fuel oil
output and you will have more of the “powder like black carbon” ash substance.
21. Is the material going to have to be granulated
before being put into the equipment?
The plastic is shredded into about ¾” cubes or squares, then fed by a pneumatic
conveyor to be preheated, then into the reactor for processing.
22. Do you have a preliminary analysis of the oil and
BTU Value? I know this will depend on the “feedstock.”, but perhaps you have some
general guidelines.
Yes, we have a SGS lab report available. The approx BTU values is: 42.46 kBTU (
10700 kcal/kg).
23. Can we get a liter sample of the oil?
Maybe, depends on where you are located. It has become difficult to send anything
combustible by mail or private carrier.
24. Is rubber mixed with the plastic a “feedstock”
or “waste”?
No effect of rubber mixed with plastic. Rubber will act as a feedstock not a waste.
25. What range of capital cost do you anticipate a
10 Ton per day unit? How many gallons of oil can we anticipate from a 85% clean
“feedstock”?
Please Contact Us for pricing, as this varies with individual
requirements. Different feedstock has different oil yield rates. PP and PE can produce
more than 75% oil, PS is approx. 55-60% and PVC has a very low oil yield rate.
