What are the traditional hydrocarbon steam reformer processes?

Introduction to the Hydrogen Production Unit:

The Daqing Refinery hydrogen production unit was designed and built by the Fushun Petroleum Design Institute in the 1960s.

Over several decades of development, the independently designed hydrogen production unit has demonstrated reliability, ease of operation, safety, and stability.

The unit's key performance indicators, such as feedstock and fuel consumption, have approached or reached world-class levels.

The maximum capacity of a single unit is reported to be 60,000 m³/h.

Varieties of Reforming Furnaces:

Different types of reforming furnaces are used in the steam reforming process, including top-fired, side-fired, bottom-fired, staged, and top-side-fired furnaces.

The most widely used furnace types globally are top-fired or side-fired.

Top-Fired and Side-Fired Furnace Technologies:

Companies with top-fired furnace technology include Foster Wheeler, Linde, LPEC, SEI, Technip, etc.

Companies with side-fired furnace technology include Haldor Topsoe and LPEC.

Differences Between Top-Fired and Side-Fired Furnaces:

The two furnace types differ in various aspects, such as furnace structure, the number of burners, furnace size, heat transfer methods, heat requirements for conversion reactions, thermal intensity, distribution of tube wall temperatures, furnace tube lifespan, operational considerations, and adaptability to different operating conditions.

This information provides an overview of the development of hydrogen production technology, the types of reforming furnaces used, and the differences between top-fired and side-fired furnace technologies.
