OLMI Reforming Process Gas Boilers

Hydrogen, ammonia and methanol production by means of steam and auto-thermal reforming is on the rise. As one of the most economic and efficient production technologies, reforming calls for the use of durable and reliable process gas boilers. To meet the demands of these complex and energy-intensive processes, there is Alfa Laval Olmi process gas boilers for highly effective and continuous heat recovery and reuse.

On the pulse of process gas boilers for steam and autothermal reforming processes

High-temperature, high-pressure process gases are chemically aggressive due to the high content of hydrogen and carbon monoxide. For ammonia and methanol reforming processes, typical gas temperatures when received by process gas boilers can exceed 920°C. Olmi process gas boilers for steam and autothermal reforming processes provide continuous, reliable and highly effective heat transfer from gas to water.

Designed for continuous and reliable heat transfer

Customized for steam reforming, Alfa Laval Olmi process gas boilers
feature exceptional thermal-mechanical design based on the use of thin, flexible tubesheets, advanced welding techniques and state-of-the-art production technology.

High mechanical and chemical resistance

All metal parts that come into contact with the process gas and are not protected by a refractory lining or cooled by water, are made in high nickel alloys; otherwise, a high-strength, low-alloy steel is used. The inlet channel, inlet tubesheet and often outlet channel are typically protected by a refractory lining, which withstands potential mechanical wear and chemical attacks by hot process gases. Extremely durable, the lining maintains the required design metal temperature of pressure parts under design conditions.

Reliable temperature control

In addition to the refractory lining, an internal bypass system for gas temperature control is typically incorporated into process gas boilers in order to address fluctuating loads and increased levels of fouling. This integrated and internal bypass system usually consists of one or more regulating valves.
