Development and application of combined trapezoid spray tray in the Rectisol purification system;

Concerning the problem of temperature rising and outofbalance of the system when the Rectisol plant is running under high load,this paper puts forward an improving scheme through actual measurement and calculation,which in turn will eliminate the bottleneck of the plant and increase the plant capacity and operation flexibility.

The Improvement of RPS System and the Development of a New Type Rectisol Process;

Simulation Analysis and Revamp Study of City Gas Rectisol Process;

Computer Simulation and Analysis of Solvent Recovery Process in Rectisol Technology;

With the aid of process software Aspen Plus,a recsitol unit of methanol wash column is transferred and set up in the software and calculation is performed.

Study on integration process of rectisol process and withdrawal of methane process by deep refrigeration;

The Rectisol process for purifying nature gas was simulated using an appropriate thermodynamic model and the current simulation software.

The situation of loss of refrigeration consume was introduced for low temperature methanol washing device, through the calculating data of analog software RPS96, reason of problem caused by insufficient refrigeration capacity was analyzed, and the appropriate solvable measures were presented, the improved result indicates that the absorbing temperature of methanol can be kept at -58.
