MEG Regeneration

MEG (Mono Ethylene Glycol) is injected to offshore pipelines to inhibit the formation of hydrates in the oil and gas production pipelines and related facilities. MEG Regeneration Package removes water from MEG solution and produced Lean MEG is re-injected to the offshore.

TEG Dehydration

TEG Dehydration Package is used to remove water from the natural gas stream in order to meet the pipeline quality standards. This process is required to prevent hydrates formation at low temperatures or corrosion problems due to the presence of carbon dioxide or hydrogen sulfide (regularly found in natural gas). Dehydration, or water vapor removal, is accomplished by reducing the inlet water dew point. The wet gas is brought into contact with dry glycol in an absorber. Water vapor is absorbed in the glycol and consequently, its dew point reduces.

MEG Reclamation

Formation water containing sodium chloride and other salts contaminate MEG and lead to foul the filters and heat exchangers resulting in capacity derating, frequent downtime, corrosion, and high glycol losses due to thermal degradation. MEG Reclamation Package removes all salts from MEG by applying a licensed technology of Vacuum Distillation and decontamination packages.

Amine Reclamation

Amine reclamation Package is used to remove contaminants including Heat Stable Salts (HSS), upstream carryover such as MEG and degradation product from amine solvents. Removing the contaminants from Amine solution generally results in smooth operation and prevents Amine loss.

TEG Reclamation

TEG Reclamation Package is used to remove Contaminants such as salts, lube oil, hydrocarbon condensate and corrosion products from TEG. Contaminated TEG caused fouling equipment and foaming in the system, resulting in glycol losses, and insufficient process capability.

Amine Gas Sweetening

Because of the corrosiveness of H2S and C02 in the presence of water and because of the toxicity of H2S and the lack of heating value of C02, sales gas is required to be sweetened to remove H2S and CO2 to certain level. The most widely used processes to sweeten natural gas are those using MEA, DEA and MDEA.

Nitrogen Generation (cryogenic)

Nitrogen Generation Package is used to produce Liquid Nitrogen by Compressing, Cooling and Expanding Air. This process removes heat from the air and can be repeated until the air liquefies. The condensing gasses are then separated using fractional distillation to separate Nitrogen from the other gasses in air.

LPG Treatment (Molecular Sieve)

LPG Treatment Package is designed to treat sour LPG which is produced by L.E.H Unit as a byproduct and includes the required facilities for producing marketable sweet LPG. The main purpose of LPG Treatment Package is to treat a sour LPG liquid stream coming from overhead of a stabilizer column of a newly designed “Light End Hydro-Treatment Unit” located in “Bou-Ali Sina Petrochemical Complex”, Bandar Imam-IRAN, to remove water, H2S and other sulfur compounds (COS, Mercaptans). The wet acid liquid stream will be dried and sweetened by adsorption on solid desiccant bed of molecular sieve (Desulphurization process). The exhausted molecular sieve bed, which is saturated of adsorbed water and sulphur compounds, will be cyclically regenerated by hot gas and then cooled with cold gas before adsorption cycle start again. In order to assure a continuous operation, two parallel molecular sieves Treaters are provided, alternatively one in adsorption and one in regeneration.

Molecular Sieve Gas Dehydration

Molecular sieve dehydration is used to remove water from natural gas. The dehydration is necessary to mitigate problems caused by hydrate formation and corrosion. Molecular sieve dehydration units are used to give a very low water dew point to natural gas to allow for ethane extraction afterwards. These dehydrating systems typically consist of multiple adsorption columns filled with solid desiccant. The columns are cycled between adsorption, regeneration (where the desiccant bed is heated to drive off water) and cooling.

NGL Fractionation Unit

Raw natural gas contains valuable heavier hydrocarbons such as ethane, propane, butane and fraction of higher hydrocarbons. These associated hydrocarbons, known as natural gas liquids (NGL), must be recovered from the gas in order to control the dew point of natural gas stream and to earn revenue by selling these components as products for different industries. Natural gas liquids are fractionated to produce LPG.

Hot Oil Heating System

Hot oil system is high temperature heating system used for industrial processes, most often instead of steam, because of much higher operating temperatures at low operation pressure and because of significant less overall operation costs. Selection of heat transfer media and process equipment and control are two key area for evaluating in this system.

Fuel gas Conditioning Package

Most users of fuel gas require gas that is free of liquids and solids. This is particularly critical in gas turbine applications where severe damage may be caused to the turbine if the gas is not ultra clean and dry. Additionally, the fuel gas is superheated above the hydrocarbon and water dew points to prevent liquid condensation in the turbine’s combustion chambers. Metered fuel gas is normally required at a steady operating pressure and at a safe margin above dew point. Fuel gas Conditioning Package is designed to minimize installation time and costs and to maximize ease of operation.

Chemical Dosing Package

Chemical Dosing Packages are used in applications that require the mixing, storage and accurate dosing of specialized chemical reagents. They are used in applications such as water purification, chemical / food processing, mining, petroleum, utilities, Water and wastewater treatment, pharmaceutical facilities, neutralizes acidic water and scale prevention.
