Hydrotreating is a process widely used in the petroleum industry for producing high quality fuels and the most common processes from removing sulfur and nitrogen impurities. Today on #PetroKNOWLEDGE we’ll learn oil and gas hydrotreating process
Here’s how the flow of the oil and gas hydrotreating process works.
Oil and Gas Hydrotreating Process:
- Feed is mixed with recycle hydrogen stream and sent to heat exchange in a furnace for heating
- the heated feed mixture is sent to the hydrotreating packed bed reactor. The reactor outlet is cooled and mixed with water.
- the water mixed reactor stream is sent to a phase separator. The phase separator splits the feed stream to three separate streams namely a gas phase stream, an organic stream and an aqueous stream.
- The aqueous stream is rich of H2S and NH3 and will be sent out to a sour water processing unit to recover H2S and NH3. The sour water processing unit uses amine based absorption technology to recover H2S.
- The hydrotreated product is the organic stream enters a fractionator to stabilize the hydrotreated products
Here are some facts about Oil and Gas Hydrotreating Process :
- Higher pressure and temperature are used when heavier feed stocks are used.
- The hydrotreating reactions are exothermic and therefore, the reactor product needs to be cooled.
