Crude Separation Unit Analysis

Crude Distillation Unit (Unit 1100)
The purpose of the Crude Distillation Unit (CDU) is to produce a long residue, which is a feedstock of downstream RFCC unit, from a mixture of long residue and Oman Export Blend Crude (hereinafter referred to as Mixed Crude). CDU is designed to process 116,400 BPSD of Mixed Crude, consists of 40,000 BPSD of long residue and 76,400 BPSD of Oman Export Blend Crude and is supplied from the Mina Al-Fahal refinery. CDU also produces LPG, naphtha, kerosene and gas oil. CDU consists of Preheating section, Main Fractionation section and Stabilizer section. CDU LPG Merox Process Unit (Unit 1200)
The purpose of CDU LPG Merox Process Unit (CDU LPG Merox) is to remove hydrogen sulfide and mercaptans in the LPG from the bottom of the Amine Absorber (C-1251) at CDU unit. CDU LPG Merox utilizes UOP’s Merox process and its feed throughput is 2,040 BPSD. CDU LPG Merox consists of a pre-treatment section and an extraction section.
Kerosene Merox Process
RFCC LPG Merox utilizes UOP’s Merox process and its feed throughput is 29,500 BPSD. RFCC LPG Merox consists of a pre-treatment section, an extraction section and caustic regeneration section. Propylene Recovery Unit (Unit 2700)
The purpose of Propylene Recovery Unit (PRU) is to recover polymer grade propylene from C3/C4 mixture of the RFCC unit.
