Sealing type of the light oil pump in the catalytic unit

Thread Content

We conducted a safety risk analysis on our installations some time ago, and it was required that dry gas seals be used for light oil pumps. What kind of seals are being used for the light oil pumps in your installations (such as crude gasoline pumps and deethanized gasoline pumps)? We previously used mechanical seals for those pumps

The light oil pumps (C3, C4 pumps) of our unit use PLAN11+72+76； Pumps C5 and C6 use PLAN11+52.

Our crude gasoline pumps use a single seal, PLAN11； Dual-seal for stable systems, PLAN11+52 or 53B

Why change to a dry gas seal? What is the basis?
