Title Supersonic Condensation and Separation Characteristics of CO2-Rich Natural Gas under Different Pressures

Supersonic Separation of Natural Gas Liquids by Twister Technology

The Twister supersonic separator is a unique combination of known physical processes, combining aerodynamics, thermodynamics and fluid dynamics to produce an innovative gas conditioning process. Condensation and separation at supersonic velocity is the key for achieving a significant reduction in both capital and operating cost. Twister is a proven gas conditioning technology. Condensation and ...

Effect of Inlet and Outlet Flow Conditions on Natural Gas Parameters in Supersonic Separation Process

A supersonic separator has been introduced to remove water vapour from natural gas. The mechanisms of the upstream and downstream influences are not well understood for various flow conditions from the wellhead and the back pipelines. We used a computational model to investigate the effect of the inlet and outlet flow conditions on the supersonic separation process. We found that the shock wave...

A Physical Absorption Process for the Capture of Co2 from Co2-rich Natural Gas Streams

A new CO2/CH4 gas separation process is presented in this paper. Capture of CO2 from natural gas is carried out using an n-alkane solvent in a conventional physical absorption process. A methodology to find optimal process condition and solvent has been developed using an advanced equation of state (SAFT-VR), process modelling-optimisation software (gPROMS), and detailed process cost estimation...

Investigation of CO2 and H2O Addition to Natural Gas for Production of Synthesis Gas

General modeling and optimization of syngas production via noncatalytic autothermal partial oxidation of methane are carried out using our developed scientific software which was based on the minimization of total Gibbs energy. In this work, a novel application of the direct search and Newton-Raphson methods was introduced to apply to optimization of a complex chemical reaction. Sensitivity ana...
