Help – catalytic reforming, hydrogenation, and coking flare pipelines in my company
Thread Content
Since operations began, the liquid level in our reforming unit’s low-vacuum tanks has increased by several units per shift; the specific gravity obtained from sample tests is 931.0 Kg/m³, with a sulfur content of 1751 mg/L. It’s not clear where this sulfur is coming from.
It must be caused by the gas system. From the secret passage, it should be a relatively heavy fraction; if it’s not an absorbent, then it could be brought in by the activation of some high-pressure safety valve – so it’s necessary to thoroughly check the safety valve system.
