Biogas Production from ships and seaports wastes in Libya and using as an Alternative fuel

Abstract

Recent years have grown interest in environmental issues, especially the transfer the seaports into green ports. This has made biogas production from wastewater a particular focus as a sustainable solution that combines economic and environmental benefits. This study aims to investigate the feasibility of producing biogas from wastewater in Libyan seaports and using it as an alternative fuel for power generation. A biogas production plant model was designed, with emphasis on the selection of materials such as 661 stainless steel to ensure durability. Data on the quantities of wastewater and biogas produced were analyzed, and the results showed that the average volume of gas produced from the anaerobic fermentation process for a population of 23, 200, 2,000, and 300,000, respectively, was (6,325, 30,375, 303,75, and 455,625) cubic meters. The extracted quantities of wastewater, organic matter, and biogas fall within specific ranges, indicating that these values can be influenced by various factors such as lifestyles and waste management methods. The efficiency of a wastewater biogas production system depends on a delicate balance between tank size, pump type, specialized bacteria (such as methane-producing thermophiles), pressure and temperature control systems, and safety valves and a water vapor separation system to ensure safety and optimal performance. This system can be adapted to a variety of locations, such as seaports, where tank sizes, biogas production rates, and the amount of organic waste can be adjusted based on the needs of each location.
