1 Executive Summary

1.1 IMMA Global Group at a Glance

IMMA Global Group is a Turkish – Belgium joint-venture with worldwide partnerships and joint-ventures as a dedicated manufacturer and supplier of

1. Mining Machinery including turn-key crushing & screening solutions with entire required auxiliary equipment, transporting, accommodating and facilitating solutions with worldwide partners as Sandvik, Metso, Mercedes-Benz, ABB

2. Steel Structures as a unique and custom based projects for accommodation (from low-cost housing till multi-floor apartments), schools, kindergarten, hospital/clinic, hangars, facilities, etc. with a quick and reliable cost effective building solutions as per EU standards.

3. EPC Contracting for primary & secondary oil processing, grain processing, storage areas, refurbishing and renovating/upgrading

4. Ship building and repair of tanker ships (up to Suezmax ships), oil rigs, jack-up barges, accommodation barges, tugboats, crew-boats, etc.

IMMA has developed a unique processing process for primary and secondary crude oil processing and distilling. In this project the obtained products are are brought by a highly effective solution without entering a hydro-cracking or a catalytic-cracking method, which enables a cost effective investment for crude oil refine. As you’ll see in the following pages the final products will be sufficient for this investment and develop the business in terms of pay-back period and enlarging the investment area as power plantation or product enriching. Unlike current other methods which use additives to increase the octane, IMMA utilizes the method of isomerisation and aromatization to refine. Our plan calls for setting up a power generating unit, to be built on a barge with a capacity of from
2,5MWe up to 1 GWe on a modular basis structure to multiple the units and/or divisions to enable an increase capacity & quality. This unique processing process brings the highest rate of cost/benefit ratio in limited volumes as a compact crude oil processing to produce in-house the required HFO, SRFO, LFO, LPG, etc. IMMA’s solution is a minimized regular hydro-cracking method of crude oil processing via utilizing the method of isomerisation and aromatization.
The methodology is based on a processing of hydrocarbons obtained through the direct distillation of crude oil, namely the straight-run gasoline (fraction at 85-180°C). In order to process straight-run gasoline, we use the process of “Metaforming”, which increases the octane number of the crude, followed by the
production of motor fuels of Euro 3 and Euro 4 standards (trade marks of AI-92, AI-95 & AI-98).

The purpose of IMMA’s oil refinery is to be a solution supplier for major distilled oil products as gasoline, LPG, diesel and fuel-oil with a cost effective investment, low costed operating and limited timeline. So to be able to come with local potential solution provider. This business plan calls for setting up a modular mini processing solution with each has the capacity to process 3.600 bpsd of crude to naphtha and produce raw material for power generating.

IMMA brings a unique solution to generate power from crude oil by 2 processes:

I. CRUDE OIL: Major refined oil products as diesel (Euro2, Euro3 or Euro 4), gasoline (AI92, AI95, etc), LPG and fuel-oil

So IMMA’s Compact PowerShip calls for 3 major elements:

1. Crude Oil Processing: Setting up various modular mini processing solution with each has the capacity to process 112.000 bpsd of crude to naphtha and produce gasoline, diesel, LPG, kerosene and fuel-oil through the same process.

2. HFO Power Plant: “Heavy Fuel Oil” power plant to produce electricity

3. Floating Units:
(a) processing
(b) Power Plant
(c) Accommodation

Those will be installed on a floating barge to enable a flexible mobilization in terms of start-up and offshore investment advantages.

2.3 The Technology: IMMA’s Unique Crude & Reforming Process

IMMA’s technology is based on processing the crude to achieve major products. Obtained 2 major processing for oil processing of Mini Refinery Plant, as a complete solution from crude oil to high-octane refined oil products. Our solution will consist of 2 major units:

1. Primary Basic processing Plant: Crude Oil Processing
2. Metaforming – Secondary, “Naphtha” Processing

Mini-refineries for the production of motor fuels (oil) are fully equipped modular units, suitable for immediate installation on the site and to be launched within three weeks after the equipment is delivered to the to the prepared construction site.

* 3.600 bpsd is a preliminary estimated figure to show & generate some ideas for this introduction.

Fractionation of stable gas condensate (low-octane gasoline) and release of fraction of 30-80°С and 80-200°С. Catalytic isomerisation and aromatization. of fractions 80-200°С and release of unstable catalyst Stabilization of unstable catalyst and producing of LPG and stable catalyst Fractionation of stable catalyst and release of target gasoline product (with end boiling point up to 215°С) and removal of heavy residue. Mixing (compounding) of gasoline fraction (with end boiling point up to 215°С) with the fraction of stable gas condensate of 30-80°С and producing high-octane gasoline in addition to diesel, fuel oil and LPG.

In the process of aromatization., the catalyst loses its activity. To restore the activity of the catalyst oxidative regeneration is used. Technical nitrogen is used as oxygen-containing gas. To prevent significant coke-sedimentation, reactors are to be stopped for regeneration after every 300 hours of operation.

2.4 Products of Oil Refinery

  • Naphtha (straight-run gasoline) – with final boiling point up to 185 °C. Naphtha is then used as a basic component in the production of high-octane gasoline.
  • Diesel fractions (mini refinery distillate) – A typical temperature of the product is in the range from about 185 ° C to 340 ° C. The product was further subjected to distillation to separate kerosene and diesel fuel.
  • Straight-run fuel oil (residual fraction) – a fraction remained after the primary distillation with an initial boiling point of about 320 °C. This product is  commonly used in the production of various.

Processing of crude oil in the refinery with a specific gravity of 0.865 will produce light naphtha at the volume of 20% of crude, 30% middle distillate (gasoline  and kerosene fraction), and 50% straight-run fuel oil, as residual fraction.

2.5 The Inlet / Outlets of Facility

Inlet : Crude Oil (API 31-42)
Outlet : AI95 Gasoline (Or AI92)
