Removal of organic silicon compounds from refinery hydrocarbon streams

A process for extracting a silicon-containing compound from a refinery hydrocarbon stream, the process comprising:

• providing a refinery hydrocarbon stream from an upstream process unit, wherein the refinery hydrocarbon stream comprises a silicon-containing compound;
• and
• contacting the refinery hydrocarbon stream comprising the silicon-containing compound with an alkaline agent in an alkaline bed, thereby extracting at least a portion of the silicon-containing compound from the refinery hydrocarbon stream;
• and
• hydrotreating the refinery hydrocarbon stream after the contacting.

A system for extracting a silicon-containing compound from a refinery hydrocarbon stream, the system comprising:

• an upstream process unit,
• an alkaline bed, and
• a hydrotreater,
• wherein, the alkaline bed is upstream of the hydrotreater, and
• wherein the alkaline bed is configured to receive a refinery hydrocarbon stream comprising the silicon-containing compound from the upstream process unit such that the refinery hydrocarbon stream comprising the silicon-containing compound contacts the alkaline bed, thereby removing the silicon-containing compound from the refinery hydrocarbon stream before hydrotreating.
