Abstract

Due to the limitations of existing natural gas fumigation systems, including the bypass and injection systems, there is a need for the design of a new system with fewer restrictions. This paper addresses this issue by conducting a thermodynamic analysis of the performance of a new system, called the ejector gas perfuming system, across a wide range of parameters, including primary gas pressure (Pg = 500-5500 kPa) and secondary gas pressure (Ps = 200-400 kPa). The results demonstrate that the ejector's performance is primarily influenced by two key factors: the pressure at the ejector's exit and the ejector's entrainment ratio. The findings indicate that the ejector performs optimally when Ps > 250 kPa and 1850 kPa ≤ Pg ≤ 5200 kPa. Outside of this range, its performance declines.

Highlights

· A new ejector-based gas perfuming system is proposed to overcome the limitations of existing technologies.
· Its performance is evaluated under different gas pressures (Pg: 500–5500 kPa; Ps: 200–400 kPa).
· Optimal performance is achieved when Ps exceeds 250 kPa and Pg ranges between 1850 and 5200 kPa.
