ABSTRACT = {The supersonic separator has proved to be an effective method to condense and separate CO<sub>2</sub> from natural gas, and the inlet temperature plays a vital role 
on condensation characteristics of CO<sub>2</sub> in the supersonic separator due to the instability temperature of wellhead natural gas. In this paper, the physical and 
mathematical models for the supersonic condensation process of CO<sub>2</sub> in the natural gas were established on the basis of CO<sub>2</sub> droplet surface tension, 
nucleation and growth model. The flow and condensation parameters were investigated under different temperature conditions. The results show that when 
the inlet gas pressure is 8.0 MPa, the inlet gas temperature is 280 K and the CO<sub>2</sub> content is 0.15, the condensation position is x=240.25 mm, the maximum 
nucleation rate is 1.14×10<sup>21</sup> m<sup>-3</sup>·s<sup>-1</sup>, the maximum droplet radius is 2.146×10<sup>-7</sup> m, the maximum droplet number is 8.20×10<sup>14</sup> kg<sup>-1</sup>, and the maximum 
humidity is 0.0446. The decrease of inlet temperature makes the droplet reach a greater growth rate and a larger radius of droplet at nucleation. With 
the decrease of the inlet temperature, the condensation position moves forward, the maximum nucleation rate and the droplet number, the droplet radius and 
the humidity of CO<sub>2</sub> increase.},
