Waste treatment by pyrolysis - the process          patented process !

The P.I.T. Pyroflam process, developed originally by Serpac Environnement,
a French industrial company, is a gasification process
aimed at the valorisation and conversion to energy of various solid wastes,
including municipal solid wastes, industrial wastes, sludges, animal and meat wastes.
BS Engineering S.A. acquired the patent, user's licence and trademark
of the P.I.T. Pyroflam Process and Serpac Environnement's trademark
in July 1999.

5 = extractor of recyclable solid residues; 6 = process air fan; 7 = emergency stack ;
8 = post combustion chamber ; 9 = combustion air fan;
10 = recovery boiler; 11 = fly ash collection ; 12 = flue gas cleaning reactor ;

16 = stack; 17 = turbo-alternator ;

The P.I.T. Pyroflam total pyrolysis process is based on heating a hydrocarbonated load without oxygen input at a fairly low temperature (between 450° and 750° C).    This heating operation breaks down the organic materials, producing a thermolysis gas and a highly carbonated solid residue which is transformed into burnable gas by gasification.

A highly efficient thermal conversion process

Simple
Not limited by the calorific value of the waste
Producing less flue gases
Less heavy metals, fly ash, dioxins and furans
Maximum valorisation of the energy contained in waste materials
Without environmental nuisance
Low running costs
