History of Pyrolysis
Description of Balboa Pacific Corporation’s Technology:
Pyrolytic Gasification is by no means new. The principals were first brought forth in 1958 at Bell Laboratories within the United States of America. Thereafter, a number of universities and organizations around the world started R&D programs. The word Pyrolysis meaning, chemical change brought about by heat is widely used, even by incineration technologies, which have tried to escape their roots in oxidation and combustion because of the problems prevalent with both. Gasification is a term being used to describe the chemical reaction and molecular break down, or degradation of materials.
The first Pyrolytic Gasification systems were brick ovens using indirect heat / low oxygen that were made of firebrick. Waste was placed into the unit - the unit was sealed and heat applied. After the process of degradation was completed, the oven was opened and emptied to make room for the next batch. These systems were known as batch-by-batch systems. This format was first introduced commercially in the early 70's. They were limited by volume and, after some time in operation, were also found to have defects that related to the mortar that was used to bind the bricks together. During the late 70's and early 80's, R&D turned away from batch-by-batch systems, which at that time, had found some commercial success processing Hospital Waste and continual-flow systems, which were a form of rotating Auto Clave. This format was later refined into cone shaped retorts in order to direct the gas stream to a central point for evacuation. This refined cone design first showed up in England, then the US and Germany, followed by Japan, Canada and the Netherlands.
