EXTRACTION OF CRUDE OIL FROM PLASTIC WASTE USING PYROLYSIS TREATMENT

Abstract

Plastics have woven their way into our daily lives and now pose a tremendous threat to the environment. Over 100 million tons of plastics are produced annually worldwide, and the used products have become a common feature at over flowing bins and landfills. Though work has been done to make futuristic biodegradable plastics, there have not been many conclusive steps towards cleaning up the existing problem. Here, the process of converting waste plastic into value added fuels is explained as a viable solution for recycling of plastics. Pyrolysis runs without oxygen and in high temperature of about 300°C which is why a reactor was fabricated to provide the required temperature for the reaction. Converting waste plastics into fuel hold great promise for both the environmental and economic scenarios. Thus, the process of converting plastics to fuel has now turned the problems into an opportunity to make wealth from waste. The conversion of oil from plastic has dual benefits. First of all the oil produced can be used as a fuel for domestic purposes and also in vehicles and industries when further refined. Secondly, the various types of pollution caused by waste plastics can be minimized. Plastic in the first place is manufactured from natural gas specifically from ethane which is a constituent of natural gas. Therefore the waste plastic can be converted back into it. An increase in energy demand, stringent emission norms, and depletion of oil resources have led researchers to find alternative fuels for internal combustion engines. On the other hand waste plastic pose a very serious environmental challenge because of their disposal problems all over the world. Plastics have now become indispensable materials in the modern world and their application in the industrial field is continually increasing. In this context, waste plastic solid is currently receiving renewed interest. The properties of the oil derived from waste plastics were analyzed and compared with the petroleum products and found that it has properties similar to that of diesel. In waste plastic into liquid fuel by using pyrolysis process, a pyrolysis unit is designed, fabricated, and evaluated for various kinds of plastic wastes, properties of liquid fuels obtained are determined. In this project work an attempt has been made to investigate the conversion of household
