Abstract
Abstract
The paper aims to outline the technical challenges and opportunities associated with implementing blue hydrogen production in the Panchevo oil refinery. It will emphasize a viable pathway for decarbonization, focusing on optimizing carbon capture and storage technologies, ensuring cost-effectiveness, and addressing environmental concerns. The scope includes contributing to the refinery's sustainability goals and fostering innovation in the energy transition. The approach involves utilizing Aspen Hysys for CO2 emission calculations, assessing all refinery emitters, and defining the carbon footprint. The required CO2 reduction for European blue hydrogen standards has been determined. Physical space needs for a carbon capture unit are analyzed, with parcel allocation. Three hydrogen production scenarios are evaluated using facility data and specialized software. This comprehensive methodology ensures a thorough examination of technical challenges and opportunities in implementing blue hydrogen production at the Panchevo oil refinery, emphasizing sustainability and adherence to European standards. The study employed Aspen Hysys with a Gibbs reactor to model fuel combustion, optimizing Gibbs free energy for phase and chemical equilibrium. Adjusting air flow to measured oxygen values, it was found that HPU emissions contribute 41% to total refinery emissions. Steam Methane Reforming data revealed current hydrogen production and the plant's underutilization at 50-60% capacity, indicating room for expansion. Implementing carbon capture technology enables the monetization of premium blue hydrogen. Analysis of three scenarios, with additional daily hydrogen production of 20t/day, 35t/day, and 50t/day, consistently showed a 74% emission reduction to meet blue hydrogen standards, equating to 350,000–530,000 tCO2/year for capture and storage. The proposed solution involves transporting captured CO2 via a pipeline to a depleted gas field located 40 km from the refinery, aligning with sustainability goals.
