The refinery operates continuously for many years with hot, flammable, corrosive and high-viscosity media. From crude oil distillation, catalytic cracking, hydrocracking, hydrotreating to reforming, every process requires well-sealed pumps and compressors. Mechanical seals, dry gas seals and suitable auxiliary systems help reduce leakage, ensure safety and extend the operating cycle.
High-temperature heavy oil, sulfur-containing media and catalyst particles, high-pressure hydrogen all create harsh working conditions for the seal face. Leaks of hot hydrocarbons pose a risk of ignition, so seals must be stable, thermally resistant and have a good monitoring system.
Metal bellows seals for high-temperature pumps, double seals with a barrier fluid system for toxic media, cooling, quench and flush auxiliary schemes according to API 682, and dry gas seals for hydrogen compressors, gas compressors. Seal face materials like silicon carbide help increase wear and heat resistance.
