Info Middle Alahmadi Refinery
Mina Al-Ahmadi Refinery (MAA) was inbuilt 1949 as a simple refinery with a refining capacity not exceeding 25,000 bpd to supply the native market with its needs of gasoline, kerosene and diesel. The refinery is situated forty five km to the South of Kuwait City on the Arabian Gulf. It covers a total area of 10,534,000 m2.
Following the establishment of KPC and the restructuring of the oil sector, ownership of the refinery was handed from Kuwait Oil Firm (KOC) to Kuwait Nationwide Petroleum Company (KNPC) which became answerable for the oil refining and gasoline liquefaction operations in Kuwait. Within the early 1980’s as a part of an general plan
to improve the refining industry and broaden the refineries , work began on two bold projects to modernize Mina Al-Ahmadi Refinery, particularly the MAA-Refinery Modernization Undertaking (MAA-RMP) (which was accomplished in 1984) and the Additional Upgrading Challenge MAA-FUP (which was commissioned in 1986). Throughout the framework of these two initiatives, 29 new units were constructed at this refinery which has now grow to be one of the world’s trendy refineries when it comes to both refining capacity, which exceeds 460,000 bpd and the advanced technology it employs.
Mina Al-Ahmadi Refinery Modernization Undertaking (RMP) was mainly supposed to provide the local and world markets with low sulphur -content petroleum products, and to reduce dependence on gas as fuel, offering cheaper and more stable gas to the country’s power technology plants.
The Additional Upgrading Venture (FUP) was based mostly on extra comprehensive view of the future of petroleum product markets in order to maximise profits and ensure a stable marketplace for the three refineries output. The venture additional sought to increase the share of light and medium merchandise of the distillation course of and reduce the share of gas oil in the long run output, resulting in the next return from the crude oil refining processes. The refinery now accommodates 29 new models, in addition to the outdated units, together with the crude distillation models, the Fluid Catalytic Cracking Unit, the Atmospheric Residue Desulphurization Items, the Vacuum Rerun Unit and the Sulphur Restoration unit.

In these models, the uncooked materials is separated within the distillation tower into a lot of products reminiscent of fuel, naphtha, kerosene, mild gasoline oil, heavy gasoline oil and residues. The distillates of those two models are sent to other conversion units so as to improve their specs to the required standard. These two models were constructed as part of the refinery modernization project (MAA-RMP). They supplement the production of the present crude distillation unit to boost the capability of those three CDU units to round 466,000 bpd.
Fluid Catalytic Cracking Models (FCC)
The unit was commissioned in 1986 as part of the “Refinery Additional Upgrading Venture (FUP)” with a capacity of 30,000 bpd.
In 1997, the unit was revamped and its capacity was raised to forty,000 bpd as a part of MAFP (which stands for MTBE Alkylation, and FCC revamp Project). Since that point the unit continues to play a serious function as a coronary heart conversion unit among the many three refineries , the place it processes varied feed to supply prime quality merchandise and feedstock for downstream models for further processing. The unit goal is to produce maximum Liquefied Petroleum Gases (LPG) and Gasoline (Conversation level seventy nine of LV% to gasoline ). The “Olefin” rich LPG stream (Double Bond Hydrocarbons) is further processed in downstream items to provide Propylene, MTBE and Alkylate.
FCC unit consists of the following sections
• Reactor/ Regenerator
• Predominant Fractionators
• Fuel Concentration Unit
• Power Restoration
