Steam Methane Reformer (SMR)

Steam methane reformers are the core equipment used to convert natural gas into hydrogen at industrial scale.
At Gelan, we design and manufacture high-performance SMR furnaces and modular reforming units for EPC and hydrogen production projects.

  • Up to 200,000 Nm³/h hydrogen capacity
  • Integrated heat recovery & modular design
  • Designed for real operating conditions

Steam Methane Reforming Process Overview

SMR is the most widely used and cost-effective hydrogen production technology for large-scale industrial projects. In real plants, the SMR furnace is the core unit that affects hydrogen output, energy efficiency, and long-term operating cost. 

STEP 1

Feed gas preparation

STEP 2

Reforming reaction

STEP 3

Heat recovery and purification

Natural gas is cleaned, mixed with steam, and preheated before entering the furnace.

Inside catalyst-filled tubes, methane reacts with steam at high temperature to produce hydrogen-rich gas.

The gas is further processed to improve hydrogen yield and purity.

How Gelan Improves SMR Performance?

In real projects, SMR performance is not only about temperature. It depends on how well the furnace, materials, and system are engineered together.At Gelan, we design SMR furnaces based on real operating conditions, not just theoretical calculations.

01

Reformer Furnace Structure & Heat Distribution

Uniform heat distribution directly affects hydrogen yield and tube lifetime.
Gelan design approach:

  • Multi-burner optimized layout
  • CFD-based heat flux simulation
  • Stable radiant box temperature control

Typical performance:

Better heat uniformity means longer tube life and stable operation.

Reforming Tube Material & Lifetime

Reforming tubes are the most critical and costly components in SMR.
Gelan solution:

  • High-grade alloy materials (HK, HP, Micro-alloy upgraded)
  • Enhanced creep resistance and carburization resistance
  • Optimized tube thickness and layout

Typical performance:

Longer tube life = lower maintenance cost and fewer shutdowns.

03

Burner & Combustion System

Combustion stability affects both safety and efficiency.
Gelan design:

  • Fuel-flexible burners (natural gas / refinery gas)
  • Stable flame control under varying loads
  • Optional low-NOx design

Typical performance:

low nox combustion smr furnace for mobile

Heat Recovery & Energy Efficiency

A well-designed SMR system must recover as much heat as possible.
Gelan integration capability:

  • Waste Heat Boiler (WHB) integration
  • Feed gas preheating systems
  • Steam generation optimization

Typical results:

This is where real cost savings happen in long-term operation.
