Hydrogen, Carbon Monoxide
and Synthesis Gas Plants

PPE Designs, Engineers, Fabricates, and Installs Plants to Produce Hydrogen, Carbon Monoxide, Synthesis Gas and Other Specialty Gases

Hydrogen (H2), Carbon Monoxide (CO), and Synthesis Gas (Syngas) are produced from natural gas or other hydrocarbons utilizing primarily Steam Methane Reforming (SMR), Partial Oxidaton (POX), and to a lesser extent Autothermal Reforming processes.

PPE offers a range of equipment options to generate high purity hydrogen, carbon monoxide, and synthesis gas designed for your specific application.

PPE has extensive experience with the design, fabrication, installation, and operation of these facilities.

Hydrogen is produced most commonly by steam methane reforming in which methane is reacted with steam (CH4 + H2O → CO + 3 H2) at high temperature in the presence of a catalyst to generate a mixture of carbon monoxide and hydrogen referred to as synthesis gas (syngas). Syngas produced by steam methane reforming is composed of 3 H2's for each CO which is beneficial when H2 is the desired product. This syngas is purified using pressure
swing absorption or membrane technology to yield hydrogen product (H2).

Carbon Monoxide is produced by
steam methane reforming (described in Hydrogen above) and by partial oxidation (POX) in which methane is reacted with oxygen
(2 CH4 + O2 → 2 CO + 4 H2) to generate a mixture of
carbon monoxide and hydrogen referred to as synthesis
gas (syngas). The syngas produced by partial oxidation is composed of 2 CO and 4 H2 which is somewhat more desirable when CO is the required product. This syngas is purified using a methane wash coldbox or membrane technology to yield carbon monoxide product (CO).

Synthesis Gas is defined as a mixture of carbon monoxide and hydrogen produced commercially by steam methane reforming and partial oxidation (more fully described in Hydrogen and Carbon Monoxide above). Syngas is also obtained as a by-product of various chemical processes. Syngas has many commercial applications primarily as a feedtock to a wide range of products.
