Carbon Monoxide (CO) Carbon monoxide (CO) has a long history in Minneapolis and around the world as a component of the initial attempts to produce a flammable gas to illuminate dark spaces in the nineteenth century before 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 locations around the world, replacing whale oil but still necessitating “lamplighters” to open individual valves, and light the burner (and close the valve in the morning).This manufactured gas over time found a simpler system of generation: through purposefully constructed coking ovens that transformed metallurgical grade coal to coke, for use as a source of carbon to convert iron to steel. The gaseous derivative from these ovens was a more enriched form of the original gas with a higher concentration of hydrogen and carbon monoxide, some methane, and less carbon dioxide and nitrogen. The oven design and operation became relatively standardized, and this gas became commonly known as Manufactured Gas Type B.The demand for coke expanded rapidly, as the US and Europe seemed to have an unquenchable appetite for steel. Coking operations provided 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 created additional markets in metal processing and early chemical synthesis once its properties were more fully digested.In modern times, while coke is still a vital component of steel making, many of the commercially produced carbon monoxide is created in high-tech plants located near chemical manufacturers who need an ongoing supply of hydrogen and carbon monoxide. In these plants, coal has been substituted for 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 flammable gas that is colorless, odorless, toxic and 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.While Carbon Monoxide has many uses in Minneapolis, you want to speak with someone who understand how you plan to use it and what to keep in mind.
