SORBTEH
new waste disposal utilization

SORBTEH develops a system (RHAT) for the disposal of rice husks (and other plant waste) to obtain a finished product in the form of a mixture of amorphous silicon dioxide and carbon.

A unique technological feature of the installation is the combination of low-temperature pyrolysis and gasification processes.

General view of the RHAT

Reactor unit

Continuity of operation

Effectiveness

Up to 8000 h per year (11 months 24/7)

The modular structure is designed using container-type blocks. This makes it easy to transport and deploy the installation almost anywhere.

Multi-production

The combustion chamber, based on the principle of swirling countercurrents, operates on a wide range of fuels and uses the released pyrolysis gas as fuel to heat the pyrolysis reactor (closed cycle). This reduces gas consumption and ensures continuous operation.

Low power consumption and high by-product yield guarantee high productivity.

Our technology allows us to control the amount of carbon of the final mixture.

This allows three different products to be produced in one plant:

• Sorbent

Is a material for filters and elimination of oil product spills.

• Biochar

Agromeliorant (fertilizer).

• HIS

Thermal insulation mixture used in metallurgy.

Drying 150 °C

Plant waste is loaded into the hopper at ambient temperature.

Drying at a temperature of about 150 °C.

Pyrolysis in a reactor at a temperature of 400-500 °C with the use of a special catalyst.

Pyrolysis gas combustion for reactor heating.

Obtaining a by-product (biochar, sorbent, HIC).

The excess thermal energy can be used to dry rice grains or converted into electricity.

Specification

Gasification, combined with precise process control, allows you to change the amount of carbon in the resulting mixture, and therefore control the various characteristics of the final products. In addition, more thermal energy can be extracted during the gasification process than during pyrolysis.

Power consumption

Up to 15 kv/h

Dimensions

14x2.5x3 m

Production power

480 kg/h

Gas consumption - launch (propane)

25 kg

Gas consumption - work (propane)

+/-0.015 kg/h

The modular design of the unit makes the unit mobile, the technical components are designed in such a way as to simplify the processes of deployment, folding and transportation.

The dimensions allow the unit to be transported as a typical 12-meter container

The design of the RHAT installation consists of two parts:

A

Loading unit

B

Reactor unit

Biochar

Agromeliorant is a superporous bio-coal made from organic raw materials by cold firing. Biochar is very stable and remains in the soil for thousands of years, binding and retaining trace elements and minerals until it gives them to plant roots with the help of symbiotic bacteria.
