ORC-I processes over 35,000 barrels of crude oil a day to provide completely different grade of petroleum products. The Refinery’s primary merchandise are Liquefied Petroleum Gasoline, Mild Naphtha, Heavy Naphtha, Excessive Octane Mixing Part, Motor Gasoline, Kerosene, Jet Fuels, Excessive Pace Diesel and Furnace Oil.
The refining course of starts within the distillation towers. Right here, liquids and vapors are separated into elements in response to weight and boiling level. Naphtha Hydrotreater of 3,000 BBLS capacity is designed to produce feed for Catalytic Reforming unit which convert it to excessive octane motor gasoline. The Catalytic Reforming course of end in higher octane fuels designed to satisfy the needs of immediately’s engines.
Solely about forty percent of crude oil is comprised of the components for the excessive-quality fuels we produce. The remaining parts of crude are heavy, poor performing fuels and sold as fuel oil. Kerosene, Gentle & Heavy Naphtha and LPG are additional treated to produce market grade specification fuels. Lastly, after more than 20 hydrocarbons and additives have been blended into the gasoline, the completed merchandise are held in storage tanks, ready to be shipped to customers.
Single Point Mooring
Single Point Mooring (SPM) is a loading buoy anchored offshore that serves as a mooring level and interconnect for the offloading of crude tankers. The system consists of floating hoses linked from tanker to SPM, tied to Pipeline End Manifold (PLEM) through versatile hoses and PLEM connected to a refinery storage tank by way of rigid undersea pipeline of (11.32 Km) and onshore pipeline of 2.9 Km.
Crude Distillation Unit
Crude oil is separated into fractions by fractional distillation. The fractions at the top of the fractionating column have decrease boiling factors than the fractions at the underside. All of the fractions are processed further in different refining items.
Naphtha Hydrotreater Unit
Hydro treating is a catalytic refining course of employing a catalyst and hydrogen rich gasoline stream to take away about 99% of contaminants akin to nitrogen, sulfur, oxygen, and metals from straight run heavy naphtha. These contaminants if not removed from the petroleum fractions, journey via the refinery processing items; can have detrimental effects on the equipments, the catalysts, and the quality of the finished product. Usually, hydro treating is finished previous to processes similar to catalytic reforming and isomerization so that the catalyst shouldn’t be contaminated by untreated feedstock.
Catalytic reforming is a vital course of used to transform low-octane naphtha into high-octane gasoline blending parts referred to as Reformate. A Catalytic Reformer unit processes straight run naphtha with a boiling vary of eighty-a hundred and fifty C for improvement of octane quantity. The process requires heating naphtha to a temperature of 482C to 520C after mixing with recycle Hydrogen and passing by way of a sequence of alternating furnaces and mounted-bed reactors containing a platinum-rhenium catalyst within the vapor state. The feed naphtha is transformed into excessive octane Reformate and Hydrogen. Reformate is used for MS blending whereas Hydrogen is separated from the reformate stream for recycling and used in different processes comparable to for Hydrotreating.
A part of refinery gasoline pools that incessantly presents the perfect opportunity for quality enchancment is the pentane-Hexane fraction, or gentle straight-run (LSR) naphtha. The LSR is characterized by a low octane number, ordinarily 60 to 70 research octane number (RON). Isomerization converts linear molecules reminiscent of normal pentane into higher-octane branched molecules for mixing into the tip-product gasoline. This Course of also removes Benzene from the feed. The isomerization unit is comprised of three sections, Feed Preparation, Penex and Molex and will increase the octane from sixty five to 90.
