Abstract
This paper examines the history, methodology, and technological advancements in cement production, with a focus on recent innovations and the environmental impact of the industry. It provides an in-depth review of the cement production process, its energy efficiency, and associated costs, with particular attention to the use of filters for pollution control. Various types of filters commonly used in the cement industry are discussed, including Cyclones, Electrostatic Precipitators (ESPs), Fabric Filters (Bag Filters), Hybrid Filters, Jet-Pulse Filters, Multicyclones, and Packed Bed Filters. The paper highlights the effectiveness of fabric filters in capturing fine particulate matter, ensuring compliance with strict emission standards, and functioning independently of gas conditions. Additionally, the paper addresses the environmental challenges of cement production, particularly CO2 emissions from fossil fuel combustion and limestone calcination, and explores alternative fuels such as tire-derived fuel (TDF) and plastic waste (PW) as potential solutions. Furthermore, the paper analyzes the economic aspects of filter operations, considering factors such as filter type, energy consumption, regulatory compliance, and maintenance, emphasizing the potential for cost savings and improved operational efficiency through optimized filtration systems.
