Based on past flare system related project experiences, PIEDS Engineering began to write a paper on flare system optimal operation research in August 2019.

 

During the past project, we diagnosed and solved the current facilities to minimize flame instability and flaring gas amount in the flare system in the factory. Based on this experience, we developed PIELDS Engineering's diagnosis and resolution technology (Vent analysis, Process, Review, etc.) as a thesis.

  

Most oil refineries and chemical plants have flare systems designed to mitigate pressure rises in process facilities in case of emergencies that require the release of large amounts of gas due to sudden process shutdowns such as power outages. However, the rise of the flame of the flare system causes civil complaints from residents around the factory due to visible pollution, and economic loss occurs in the company, which requires constant management. In this study, two items were diagnosed and analyzed in order to derive the optimal operation method of flare system. To detect the cause of the rise in flame height, the acoustic leak detector was used to check gas leaks in safety valves and pressure control valves. By confirming the leak at 4.3% of the safety valve and 10% of the pressure control valve, the cause of abnormal sparking was derived. The information presented in this study can be easily applied to any company that has a flare system, and is expected to prevent complaints and product loss.

 

Through this, Vent Analysis, a Flare System optimization technology, one of PIELDS Engineering's technologies, was recognized for its technology and will be applied to projects in the future to achieve customer satisfaction.
