A Study On Nature Gas Storage And Peaking Technology For Complex User

As an efficient,clean energy,demand for natural gas has been the rapid growth in recent years.Along with construction of gas storage,long gas pipeline and urban gas pipeline,a different degree of peaking problems in the pipeline system have arisen in the process of production and use.We studying this subject order to solve the problem of a natural gas pipeline peaking,summarize the domestic and foreign natural gas peaking means,analysis and compare their characteristics.Pipe network simulation mathematical model has been accurately established,which is based on the fluid continuity equation,the equation of motion,the energy equation and BWRS equation of state.Fourth-order Runge-Kutta method has been used to solve the equations for steady-state simulation.The implicit central difference method which is not strictly required on the time step and is very stable,has been used to translated differential equations into difference equation for transient simulation.The Newton-Raphson method has been used to solve nonlinear equations.We hope develope a gas pipeline dynamic simulation Numerical Computation Method,reasonably solve the peaking problem.We strive to achieve continuous,safe,timely supply of natural gas to complex user,with minimum capital investment.
