The control system design of methanol reforming hydrogen based on kingview and PLC
We designed the methanol reforming the computer control system of hydrogen combining process characteristics. The combination by SIEMENS S7–200 and "kingview" software not only have better met the control demands of the hydrogen production units with carbinol method and PSA hydrogen purification processes, but also reduce the cost and improve the operability, making the technology is more and more widely used in industrial production.
A preliminary design study of a multicomponent PSA gas separation system
Abstract A model for the design of a PSA system in which hydrogen is recovered is proposed. It is found that mass transfer between the gas phase and adsorbent phase during blow-down can be omitted, while this is not the case during the repressurization step. The change in interstitial gas velocity during adsorption and desorption also needs to be considered. A basis design for a two-column system is presented and compared to results obtained by using a short-cut method. It is concluded that rigorous models are needed in order to determine exactly the important effects of interactions among the components in the gas mixture and the interactions between the different steps in the cycle.
