Cryogenic purification is normally the preferred process except when the syngas feed contains large amount of nitrogen (N 2 ), due to the close proximity between CO and N 2 boiling points (approximately 8°F). Under this situation, copper saltsolution absorption can be used instead.

Process heat comes from the combustion of gases between the coke chambers. Individual coke ovens operate intermittently, with run times of each oven coordinated to ensure a consistent flow of collectible gas. Approximately 40 percent of cleaned oven gas (after the removal of its byproducts) is used to heat the coke ovens.

The recovery of coal chemicals is an economical necessity, as they equal approximately 35 percent of the value of the coal. To produce quality metallurgical coke, a hightemperature carbonization process is used. Hightemperature carbonization, which takes place above 900°C (1650°F), involves chemical conversion of coal into a mostly gaseous ...

There are two basic methods for making liquid iron: (1) a coal based process consisting of coke ovens, a blast furnace, and a basic oxygen furnace, and (2) a process in which scrap steel and/ or DRI is melted by an electric current in an electric arc furnace (EAF). A plant using the electricity based process is called a minimill.

The absence of coke ovens and sinter plants in the FINEX process allow the capital investment of the FINEX to be reduced 20% compared to a conventional BF. Without cokemaking and sintering, the FINEX is more compact and takes less space. Continued cost advantages during operation can be realized as low cost and low quality raw materials (high alumina ore, high zinc ore, noncoking coals) use ...

The flow of coke oven gas is withdrawn from the battery by a centrifugal blower, the exhauster, and delivered through the gas vessels of the byproduct plant at a sufficient pressure for distribution as a fuel. Before passing to the exhauster, the gas is cooled in the primary gas coolers to around 25 deg C.
