Abstract

The invention provides a small and medium-sized natural gas hydrogen production device. The device comprises a furnace body, a burner, a static mixer and a first heat exchanger, and the furnace body is internally provided with a conversion unit, a steam generation unit, a desulfurization unit and a transformation unit in a flue gas flowing direction; an inlet of the conversion unit is communicatedwith the static mixer through a pipeline, an outlet of the conversion unit is communicated with an inlet of the conversion unit through a pipeline, outlets of the steam generation unit and desulfurization unit are separately communicated with the static mixer through pipelines, an inlet of the steam generation unit is communicated with a liquid phase outlet of the first heat exchanger through a pipeline, and an outlet of the conversion unit is communicated with a gas phase inlet of the first heat exchanger through a pipeline. The device integrates desulfurization and height transformation into the furnace body, and the size and floor space of the device are effectively reduced, so that investment in supporting equipment, pipelines and the like is reduced; at the same time, the heat loss in a hydrogen production process is small, and the system energy efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of natural gas hydrogen production, and in particular relates to a small and medium-sized natural gas hydrogen production device. Background technique [0002] There are two main purification processes for steam reforming hydrogen production at home and abroad, namely chemical purification method and pressure swing adsorption purification method (PSA purification method). The hydrogen production units built in the early stage in China all adopted the chemical purification method, but due to the progress of PSA technology in recent years (multi-bed pressure equalization, improvement of adsorbent performance, etc.), the recovery rate of hydrogen can reach up to 95%. Localization has greatly reduced the investment and operating costs of PSA units, making this technology dominant in new hydrogen production units. [0003] The adsorption in the pressure swing adsorption hydrogen purification device is mainly phy...
