Aqua  refining activities include the processing of Natural gas condensate into domestic petroleum products as well as Diesel, Kerosene, Octane/petrol/ms, LPG

PROCESS

Raw distill and separate valuable distillates ( Naphtha, kerosene, Diesel ) and atmospheric gas oil ( AGO) from the crude feed stock .

Primary Process Technique

Complex distillation

Process Step

– Preheat the crude feed utilizing recovered heat from the product streams.
–  Desalt and dehydrate the crude using electrostatic enhanced liquid/liquid separation ( Desalter ) .
– Heat the crude to the desired temperature using fired heaters
– Flash the crude in the atmospheric distillation column
– Utilize pump around cooling loops to create internal liquid reflux
– Products draws are on the top, side and bottom

 

Hydro treating Process:

Process Objective:

To remove contaminants ( Sulfur, nitrogen, metals ) and saturate olefins and Aromatic to produce a clean product for further processing of finished product Sales.

Primary Process Technique

Hydrogenation occurs in a fixed catalyst bed to improve H/C ratios and to remove

sulfur , nitrogen and metals

Process Step     

– Feed is preheated using the reactor effluent

– Hydrogen is combined with the feed and heated to the desired hydro treating temperature using a fired heater

– Feed and hydrogen pass downward in a hydrogenation reactor packed with various type of catalyst depending upon reaction desired.
– Reactor effluent is cooled and enter the high pressure separator which separate the liquid hydrocarbon from the hydrogen/hydrogen sulfide/ammonia gas.
– Acid gases are absorbed from the hydrogen in the amine absorber.
– Hydrogen, minus purges, is recycled with make-up hydrogen.
– Further separation of LPG gases occurs in the low pressure separator prior to sending the hydrocarbon liquids to fractionation.

Catalytic Reforming Process

Process Objective

T0 convert low-octane naptha to a high octane reformate for gasoline blending  and

to provide aromatics ( benzene, toluene and xylene ) for petrochemicals plants.

Reforming also produces high purity hydrogen for hydro treating process.  .

Primary Process Technique.

Reforming reaction occur in chloride promoted fixed catalyst bed; or continuous catalyst regeneration ( CCR ) beds where the catalyst is transferred from one stage to another, through a catalyst regenerator and back again. Desired reaction include dehydrogenation of naphthenes to form aromatics, isomerization of naphthenes, dehydrogenation of paraffins to form aromatics and isomerization of paraffins. Hydrocracking of paraffins is undesirable due to increased light-ends make.

Process Steps.

• Naptha Feeds and recycle hydrogen are mixed, heated and sent through successive reactor beds.
• Each pass requires heat input to drive the reactions
• Final pass effluent is separated with the hydrogen being recycled or purged for hydro treating

Reformate products can be further processed to separate aromatic components or be used for gasoline blending.

The above-ground tanks at the Storage terminal serve as the midstream receiving and distribution point for the gas condensate oil that has traveled to this location via pipeline‚ truck tanker or vessel. In addition to condensate oil and heavy fuel oil‚ a wide range of premium‚ light end hydrocarbons (e.g.‚ sales oil‚ naphtha‚ distillates and gasoline) are also cycled through these temporary holding points. Apart from those products arriving via pressurized pipeline‚ all of the other aforementioned transportation methods will require process pumps to unload their cargo and to transfer it to the Storage tanks. At the required time‚ the tanks will then need to be unloaded to support blending activities at the terminal‚ or for exporting by means of vessels berthed at the terminal jetty or via a supply pipeline interconnected to a nearby downstream process facility
