Carbon Monoxide (CO)

Carbon monoxide (CO) has ever since the beginning been used in Sioux Falls and around the world as a piece of the first attempts to provide a flammable gas for illumination in the nineteenth century prior to the successful demonstration of electric arc and incandescent lighting. At a “gas works,” coal was burned in a depleted oxygen environment, producing hydrogen, carbon monoxide, carbon dioxide and nitrogen. This gas was compressed and distributed in many cities around the world, in place of whale oil but still creating a need for “lamplighters” to open individual valves, and light the burner (and close the valve in the morning).

This manufactured gas over time found a more straightforward method of generation: through specialty designed coking ovens that changed metallurgical grade coal to coke, to be utilized as a source of carbon to convert iron to steel. The gaseous byproduct from these ovens was a more enriched variant of the original gas with a higher concentration of hydrogen and carbon monoxide, some methane, and less carbon dioxide and nitrogen. The oven procedures and equipment became relatively standardized, and this gas became commonly known as Manufactured Gas Type B.

The demand for coke expanded quickly, as the US and Europe seemed to have an unquenchable appetite for steel. Coking operations resulted in a regular uninterruptible source of this gas. Like many of the other technical innovations during this period, the gas was simply consumed as an energy and heat source in steel finishing, but its availability eventually spawned additional markets in metal processing and early chemical synthesis once its properties were more fully digested.

In our everyday life, while coke is still a vital ingredient of steel making, many of the commercially produced carbon monoxide is generated in world-class plants located near chemical manufacturers who need an ongoing supply of hydrogen and carbon monoxide. In these plants, coal has been supplanted by steam reforming of natural gas, again in a somewhat depleted atmosphere so that the natural gas carbons are only partially oxidized to carbon monoxide, rather than fully oxidized to carbon dioxide.

Carbon monoxide is a colorless, odorless, toxic, flammable gas that has many applications. It is used in organic synthesis to produce everything from ethylene to dimethyl ether (DME) and methanol. CO can be used in the textile industry to test flame resistance. Grade 4, 99.99% pure CO can be found in electronic and semiconductor applications. High purity CO has prevalent application in lung diffusion mixtures, mixed with high purity oxygen, helium and nitrogen to create a breathing atmosphere to measure pulmonary functions by measuring exhaled CO concentrations over a series of breathing cycles. And the largest PurityPlus requirement utilizes Grade 4 Carbon Monoxide in carefully prepared cylinders to blend highly accurate and stable trace level mixtures for environmental, health and safety monitoring equipment calibration.
