No, waste gas from pyrolysis plant has no polution, we are using exaust gas recycling system. The uncondensable gas will be recycled to heat the reactor again. This is heatable.
From our pyrolysis plant , there are 2 kinds of gas, one is gas from feeding material, like coal, wood etc, this gas will go through the dedusting system, gas after dedusting system is very clean, almost like steam. We have the SGS report for this part gas, it can reach international standards. Another part gas is uncondensible oil gas, this part gas we will recycle to furnace for heating reactor as energy. So gas no pollution.
