Technology
SHC / Galoter technology. Pyrolysis with a solid heat carrier
SHC technology is a continuous thermochemical processing based on pyrolysis. It efficiently converts a wide range of materials — from solid fuels to industrial and municipal waste — into liquid and gaseous fuels as well as chemical products, and scales to the required capacity.
Key feature
The key feature of SHC technology is the use of a circulating solid heat carrier — heated ash produced by burning the residual organic mass of the semi-coke. This approach ensures efficient use of process energy and stable operating conditions.
Principle
How the process works
Feedstock preparation
Crushing, drying and feeding the raw material into the process.
Pyrolysis
Thermal decomposition of the feedstock by a solid heat carrier without oxygen access in a drum-type reactor.
Product separation
Separation of the vapour-gas products from the mixture of the solid pyrolysis residue (semi-coke) and the heat carrier.
Condensation
Condensation of the vapour-gas mixture, yielding liquid hydrocarbons and non-condensable gas.
Heat carrier regeneration
Burning the residual organic mass of the semi-coke to produce heated ash, returned to the process as the solid heat carrier.
