Evaluating the Feasibility of Utilizing Flare Gases from Daura Refinery as Fuel for Gas Turbine Operations

Abstract

The flare system at the Daura refinery collects various flammable gases from different units, which are typically burned off in the flare stack, releasing water vapor and carbon dioxide. This study explored the feasibility of utilizing these flare gases as a fuel source for operating the gas turbine type Ms5001pa, installed at the Refinery, instead of using fuel oil. The study's findings indicate that it is feasible to operate the gas turbine using flare gases, achieving 56% of the design output capacity. Notably, the research also demonstrated that using flare gases as Fuel is more advantageous than using natural gas, which the turbine's manufacturing company recommends. This is significant because flare gases help optimize the turbine's performance and contribute to environmental sustainability by reducing the direct release of these gases into the atmosphere. Additionally, the results highlighted substantial financial benefits associated with using wasted flare gases instead of fuel oil. By repurposing flare gases, the Refinery can reduce the costs associated with purchasing fuel oil and reduce emissions, thereby aligning with global environmental standards. Overall, the study underscores the potential of flare gases as an economically and environmentally superior alternative to traditional fuels, paving the way for more sustainable operations within the Refinery. The shift to flare gases thus represents a win-win scenario, enhancing operational efficiency and environmental stewardship.
