Design Modification Study on DME direct synthesis technology

摘要

Korea Gas Corporation(KOGAS) has developed a process in which syngas is produced from natural gas and converted to dimethyl ether(DME) using a single-step reactor. We had conducted the study on the scale-up of the plant based on the operation experience of demo-scale plant and the numerical analysis result of the pilot-scale fixed-bed tubular reactor. Those studies didn't pay attention to the improvement of the process performance, but tended to center around the simulation of the plant withespect to development and validation of the model. In this study, we have conducted the simulation reflecting the result of a reactor modeling and the real operation data of demo-scale plant. And based on this simulation result, we make some modifications of the conceptual design of commercial-scale plant to improve its performance.
