Is non-condensable gases toxic from waste plastic pyrolysis?

When you consider using waste pyrolysis plant to treat waste plastic, you will not only consider the benefits that can be obtained from waste plastic recycling, but also consider whether there will be secondary pollution when using waste pyrolysis plant to treat waste plastic. Here, we will focus on analyzing whether the problem of gas emissions during the recycling of waste plastics will cause secondary pollution.

Firstly, in the process of processing waste plastics, the pyrolysis plant needs to use fuel to generate smoke; secondly, in addition to fuel oil and carbon black, a small amount of exhaust gas is generated after the waste plastics are cracked. As a professional equipment manufacturer with nearly 10 years of experience, our company DOING has done a lot of research and tests on the emission of flue gas and exhaust gas. At present, we have a very practical and effective device to deal with flue gas and exhaust gas. Here we focus on the treatment of exhaust gas.

The exhaust gas, also known as non-condensable gas, comes from C1-C4, mainly methane, followed by a small amount of hydrogen sulfide gas. It is well known that hydrogen sulfide gas is a toxic gas, which produces odor and toxic gas sulfur dioxide during combustion. After analyzing the composition of the exhaust gas, we learned that the main gas is still combustible methane. In order to consider environmental protection and energy saving, we have a special system to burn the exhaust gas in the furnace of the cycler. At the same time, in order not to cause secondary pollution of hydrogen sulfide in the combustion process, we have added a set of professional hydrogen sulfide removal device during the exhaust gas return to the furnace for combustion. Remove the hydrogen sulfide in the tail gas, leaving only clean and combustible methane gas. This avoids secondary pollution during the combustion process of the recovered exhaust gas.
