Abstract

Research Subject: Other waste incinerators and other high-temperature systems designed to dispose of garbage are referred to as heat treatment systems. The burning of waste materials, such as garbage, converts them into ashes collected on the waste floor, exhaust gases, very small particles and, most importantly, heat, which can be used to generate electrical power.

 

Research Approach:

In this research, firstly, the energy and exergy efficiencies of a waste incineration cycle, along with utilization of Lorestan petrochemical waste as an additional fuel for waste incineration, are investigated. In this way, the amount of energy needed to produce the required water vapor to disable the catalyst Ziegler-Nata was calculated for the production of linear stylistic polyethylene. Subsequently, a simple model for the inactivation reaction of Ziegler-Nata catalysts was presented using the steam generated by the waste incinerator, and then the mathematical equations for these reactions were obtained using the primary reaction law. By introducing these reactions into the reaction model, a new equation for the reaction model was obtained that covers the moments after the time of deviation to an acceptable level. This indicates the overcoming of inactivation reactions on the reactions of active centers production in the final stages of the reaction.

Main Results: The energy and exergy efficiencies of the waste incineration cycle along with the use of Lorestan petrochemical waste as an additional waste gas were investigated and thus the amount of energy needed to generate steam to disable Natal Ziegler catalysts in the production of linear linear polyethylene was calculated. To initiate this, the combined cycle was proposed and its energy and exergy efficiencies were investigated. Also, by changing the key components such as the ammonia solution composition, the ammonia distillation temperature and the input and output pressures of turbine, a way to achieve the energy needed to generate the steam needed to deactivate the Nitra zigzag catalyst in the production of linear linear polyethylene was developed.
