• Hydrogen. High pressure. High temperature. This is requiring, no, screaming for at least 2¼

Cr steel.

• As cars for example, do not perform well on heavy fuel oil, it is essential to produce lighter

fuels, such as petrol or diesel, from petroleum.

• One of the methods applied by the oil industry is to break, or crack, the long carbon chains of

petroleum using a process called 'hydro cracking'.

• High pressure hydrogen at high temperatures are used to create lighter fuels from basic

compounds via a catalyst.

• Hydrogen molecules form a bond with the shortened carbon ends, increasing the hydrogen

level in the fuels.

• More hydrogen means more combustion energy. An extra bonus is that hydrogen is the

cleanest fuel there is.

Hydro Crackers: Cases

• Challenge / question

• Hydrogen is clean because all that is left

after combustion is clean water. However,

there is one hiccup.

• Processing hydrogen is extremely difficult.

The mere fact that hydrogen molecules

are particularly small makes it hard to

separate them.

• In addition, producing lighter fuels

requires hydrogen at high pressure and

high temperature. This demands a special

material, so-called 2¼ chromium steel.

• One of the characteristics of this steel is

its extreme sensitivity to rupture,

therefore, perfect workmanship is required

to process it. A client asks us to supply a

hydro cracking installation.

Hydro Crackers: Cases

• Our solution

• We design a heat exchanger, where both the

shell and tube side are made of 2¼ Cr steel.

• As the inside hass parts that come into contact

with hydrogen, a layer of stainless steel is welded

on. Aside from its sensitivity to rupture, 2¼ Cr

steel is exceptionally strong at high

temperatures.

• This helps to keep the thickness of the

equipment within bounds. In order to avoid the

steel rupturing, the temperature during the

welding must remain as constant as possible.

Therefore, it is vital to keep the temperature of

the heat exchanger at a couple of hundred

degrees during specialist welding activities,

sometimes even for weeks. Next, the exchanger

must gradually cool down to prevent it from

rupturing. This is called step-cooling. Examples

of sheets at the same temperature, followed by

destructive tests, enable us to fine tune the

conditions required to manufacture this

equipment. We supply the specified heat

exchanger, designed according to the required

quality procedures, certification and in time to the

client.
