Sponge Iron Production Process - Arij Trading
2021-5-13 Market share: About 23% of sponge iron total production. 4) Tunnel furnace process . This process is the oldest direct reduction method. In this method, Thermal coal is mixed with iron ore as a reducing agent. Natural gas generates the required reduction temperature, and reduction is performed on Silicon Carbide (SiC) Crucibles in a tunnel furnace.

Iron Sponge Process Oil and Gas Separator
Iron Sponge Process. The iron sponge process uses the chemical reaction of ferric oxide with H2S to sweeten gas streams. This process is applied to gases with low H2S concentrations (300 ppm) operating at low to moderate pressures (50-500 psig). Carbon dioxide is not removed by this process.

Iron Sponge Unit Design Procedures - gas-compressorfo
2009-9-19 The iron-sponge vessel is either internally coated or clad with stainless steel. The superficial gas velocity (that is, gas flow rate divided by vessel cross-sectional area) through the iron-sponge bed is normally limited to a maximum of 10 ft/min at actual flow conditions to promote proper contact with the bed and to guard against excessive pressure drop.

Iron Sponge Process - an overview ScienceDirect Topics
An example of a hydrogen sulfide scavenger process is the iron sponge process (also called the dry box process), which is the oldest and still the most widely used batch process for sweetening of natural gas and natural gas liquids (Anerousis and Whitman, 1984). The process was implemented during the 19th century and has been in use in Europe and the United States for over 100 years.
