What is an Iron Oxide System (IOS)?  

The Iron Oxide System is used to remove hydrogen sulfide (H2S) in the gas sweeting process. It can be a single vessel or a multi-vessel piece of equipment. The pellets of iron oxide reacts with H2S, creating a chemical reaction producing iron sulfide (FeS/feS2) and water. 

Key parts of an Iron Oxide System (IOS) 

Keeping up with maintenance is crucial when trying to succcessfully operate Iron Oxide System. Faulty and worn out parts can affect the systems operations and overall safety when operating. Croft Supply provides parts that play an essential role in the operation of the Iron Oxide System. See below the key parts of an IOS.

Pressure Safety Valve- Prevents the pressure inside an IOS from exceeding the safety limits. If that specific limit is reached, the valve opens, releasing the pressure and setting it back to safe levels.

Pressure Gauges- Monitor and display the gas pressure that is flowing through the vessel by comparing inlet and outlet pressures. 

Thermowells- These are utilized to protect temperature sensors from exposure to the process fuilds when being inserted into the vessel.

Liquid level controller- Monitors and measures the liquid level that is collected at the bottom of the vessel. It triggers the dump valves when the liquid level exceeds a specific amount.  

Dump valve- Removes the condensed liquids by opening and releasing what is collected at the bottom of the vessel.
