Question

Distinguish between incineration and pyrolysis 2points each

Answer 1

Pyrolysis, is also called dry distillation, thermal decomposition or carbonization, which refers to the process of heating the organic matter in the absence of oxygen and making it decomposition. So pyrolysis utilizes thermal instability of the organic matter, in the absence of oxygen condition, and utilizes thermal energy to make the valency of the compound break from large molecular weight of organic matter into small molecular weight of fuel gas, liquid (oil, grease, etc. ) and coke whereas Incineration is an exothermic process while pyrolysis is an endothermic process, which needs to absorb large amount of heat.

Answer 2

Like incineration, pyrolysis, gasification and plasma technologies are thermal processes that use high temperatures to break down waste. The main difference is that they use less oxygen than traditional mass-burnincineration. ... The gases can then be combusted in a secondary process.
