THERMAL MANAGEMENT

Chillers & cooling systems

Temperature control for process tools and cooling requirements for scrubbers are evaluated separately. Utility connections follow equipment specifications, with cooling status included in operating safety and interlock design.

POINT-OF-USE INTEGRATION

Exhaust treatment connected to the source

The MW plasma system is configured around gas flow after the vacuum pump, exhaust pressure and available space. Downstream scrubbing, capture and central exhaust connections depend on gas characteristics.

Conceptual flow illustration. Installation locations, piping and downstream equipment vary by project.

01 / HOW IT WORKS

Decompose. Capture. Monitor.

STEP 01

Inlet conditioning

Gas composition, flow, concentration and pressure are assessed. Steam and other reaction-supporting fluids are configured for the target gas.

STEP 02

MW plasma decomposition

Microwaves from the generator are transmitted through a waveguide. The plasma reaction zone promotes decomposition of organic exhaust constituents and other applicable gases.

STEP 03

Reaction & thermal management

Gas mixing and residence time are managed alongside reactor heat exchange. Cooling and quenching are configured to suit gas characteristics.

STEP 04

Wet treatment & particle capture

Acidic constituents and particulate byproducts are treated through water, chemical scrubbing and collection systems. Wastewater and sludge management are included in the design.

STEP 05

Monitoring & operating records

Inlet and outlet gas data are reviewed alongside power, pressure, cooling and alarms. Treatment performance and energy use are recorded over time.

Illustrative process configuration. Reaction-supporting fluids, quenching and downstream treatment are selected for each target gas.

02 / REACTOR ENGINEERING

Inside the PETRA MW system design.

Electrodeless energy delivery

The microwave generator, waveguide, plasma generation zone and reactor are integrated. The design aims to reduce discharge-electrode wear and replacement, while quartz components, the reactor and cooling systems still require maintenance.

Preheating & swirling flow

Heat around the reactor is used to preheat incoming gas. Tangential entry creates swirling flow, supporting gas mixing, residence time and contact with the reaction zone.

Steam-assisted reactions

The THC treatment concept supplies steam to the plasma reaction zone to utilize reactive species such as OH radicals. Steam input, power and reaction conditions are adjusted for gas type and load.

Heat recovery & on-demand operation

Heat recovery and electric power control are combined to improve energy utilization. For standby and backup systems, startup characteristics are considered when evaluating ways to reduce idle operating requirements.

Technology selection depends on gas type, flow and site conditions. Destruction efficiency is assessed alongside energy, byproducts, availability and maintenance costs.

05 / SMART OPERATION & SERVICE

Turning equipment performance into operating value.

Load-based power control

Gas flow, concentration and process status inform power adjustments within an approved operating range. The objective is to manage energy in response to changing loads rather than relying solely on fixed output.

Safety interlocks & operating history

The proposed configuration monitors cooling water, exhaust pressure, power, gas supply and reflected power. Alarms, safe shutdown procedures and event records are linked to abnormal conditions.

Inspection, parts & module service

Quartz components, the reactor, cooling systems, scrubbers and piping are inspected. Spare-parts plans and replacement procedures consider site access and maintenance needs.

Total operating cost & carbon management

Electricity, fuel, water, consumables, wastewater, maintenance and downtime are assessed together. Carbon impacts of electrification include electricity use and grid emission factors as well as fuel savings.

06 / PROJECT DELIVERY

A deployment process grounded in site conditions.

Process assessment → application design

Target gases, normal and peak flows, concentration changes, exhaust pressure and available space are reviewed. Reactor configuration, downstream systems and instrumentation are defined around electricity, cooling and scrubbing-water requirements.

Installation & evaluation → phased expansion

After installation and interlock checks, gas-specific treatment, power use, byproducts and operating stability are evaluated. Inspection, training and spare-parts arrangements support decisions on broader application.

QUESTIONS & ANSWERS

More about PETRA.

How does waste tire resource recovery differ from incineration?

Resource recovery focuses on recovering the carbon and hydrogen in waste tires as products. Pyrolysis, reforming and purification are used to assess hydrogen and carbon-material value, while energy use and emissions management are considered together.

Are graphene and synthetic graphite ready for immediate sale?

The business direction prioritizes validation of hydrogen and recovered carbon black. Graphene and synthetic graphite are expansion areas requiring further purification, processing, quality analysis and customer qualification. Product grades and applications depend on feedstock and process conditions.

What kinds of partners can work with PETRA?

We seek collaboration with waste tire suppliers, hydrogen and carbon-material buyers, pilot-site operators, accredited testing organizations, industrial exhaust-treatment customers and strategic investment partners.

What applications are considered for the scrubber business?

We evaluate THC / VOC exhaust and semiconductor process-gas applications. Reactors and downstream systems are configured for target gas composition, flow, concentration and site utilities.
