Medium-scale On-site Hydrogen Generation by Methanol Reforming associated with PSA 600 Nm3/h ~ 3,000 Nm3/h

To address small-scale to medium-scale on-site hydrogen generation, Ally development the hydrogen generation process based on the methanol-reforming associated with the PSA purification system. After decades of development, Ally has been granted tens of patents and formulated the Chinese standard in this field.

Ally has gotten extensive experience through the cooperation with top-ranked multi-national companies who are engaged in the on-site hydrogen supply, such as Air Liquide, Linde, Praxair, etc..

Features

• Pre-fabricated skid technology reduces the huge on-site installation workload. 

• It is a mature production technology, which can be operated safely and reliably.

• The feedstock is easy to get by a small price fluctuation, and transported and stored easily too.

• The process flow is short and simple,less land occupation and investment which can be recovered in a short period.

• Automation is high and operation is simple and easy.

• Both energy consumption and production cost are low.

• No environmental pollution.

Process Schematic

Process Description

The mixture of methanol and de-mineralized water, after pressurized, evaporated and superheated to a certain temperature, is fed into a reactor, where the reforming gases including H2, CO2, CO, etc. are formed under the action of the catalyst. The mixed gas is treated through the purification technology of PSA to get high purity hydrogen in one cycle.

Performance

• Hydorgne Capacity: 600 ~ 3,000 Nm3/h

• Hydrogen Purity: 99%~99.9995% (v/v)

• Temperature : ambient

• Product pressure: 0.8~2.5 MPa(G)
