In a previous discussion about Hydrotreating, we talked about the types of fouling present in various parts of the hydrotreater. We did not address the catalytic reactor and cleaning of reactor internals of hydrocarbon liquids and heavier hydrocarbon deposits.

Part 9: Hydrotreating

Many of the process streams in a refinery contain unsaturated hydrocarbons, sulfur compounds, nitrogen compounds and other materials (metals) that interfere with some of the refining processes. Hydrotreating is a catalytic process that makes use of by-product hydrogen from the catalytic reforming process, to saturate hydrocarbons (change a carbon-to carbon double bond to a carbon-to carbon single bond) by adding a hydrogen atom to each of the two carbon atoms. In doing so, the process removes sulfur, nitrogen and metals from a wide variety of process streams. In general, each of the major streams coming off the atmospheric tower will have a hydrotreating unit.
