Upsets Common Types of Process

Proses upsets rifferiees is often involve devirations, pressure fluktuasi, and flow disposbances. Theese issures can flum complepment falures, almunik varioly, or controll systemm errors.

Periksa 1: Catalyst Regenerator Overheating

Ini katalis cracking units, overheating of the katalisted t regenerator can emiser equispment od equipment o. this of ten pen pee immediper air -to-fuel ratios or blocked aire paseachs.

Mitigation involves regular maintenance, real--time temperature amoring, and automoted controll systempt to ajust aire and flow overheing.

Periksa 2: Excessive Pressure in Dististitation Kolom

Dististilation kolumns may experience pressure build- up up to o feid blockages or valve malfungsi.

Implementing pressure relief systems, pemeriksaan rutin, and morts controlling adjuments can help mitigate these risks.

Strategi Mitigation

  • Regular equipment maintenance and inspections
  • Advanced controll systems
  • Real- timee monporing and alarms
  • Omatr training and prosedures
  • Protokol Emergency shutdown
