LOCATION:

Ahwaz, Iran

DESCRIPTION:

In order to reach a better performance on existing desalting plants at Ahwaz production area, a project for the supply and installation of salty crude and dilution water indirect heaters is defined. Eight heaters shall be installed in four desalting plants. Each plant will be equipped with one heater for crude oil and one for dilution water. The heat capacity for heaters are 8 MW for crude and 4 MW for water respectively. The project includes basic and detail design, supply of heater vessels, burners, burner management system (BMS), instruments and piping material, installation of all items, implementation of new heaters on existing plant, commissioning. This will increase the efficiency of desalting plant and reduce the value of salt to desired figure of 29 PPM and BS&W to 0.15% volumetric content.
 

LOCATION:

Ghaleh Nar

DESCRIPTION:

This is a project to establish a new desalting plant adjacent to an existing production unit. The desalting capacity is 20000 BPD. The project consists of a two stage desalting chain, dilution water package, effluent treatment package, flare system, desulphurization package and chemical dosing packages. All utilities to support the new build are also included, consisting of, fire waters system, electrical supply, instruments and control systems and all related pumping equipment.

LOCATION:

Pazanan Gas Reservoir

DESCRIPTION:

NGL 1000 was installed in 1978 and is feeding the domestic natural gas network. The plant treats raw natural gas and separates the sweet natural gas and light liquid hydrocarbons. The capacity of the plant is 700 MMSCD (million standard cubic feet per day). Due to a reduction in supply pressure a precommpression unit was needed. The precommpression unit consisted of 4 trains (3 operating and 1 standby), each consisting of a Knock Out Drum, Compressor and Gas Cooler. Each train has a capacity of 250 MMSCD and increases the gas pressure from 100 Barg to 160 Barg.

LOCATION:

South Pars Development 15&16

DESCRIPTION:

South Pars Development 15&16 required an Electrochlorination system to prevent organic fouling in the onshore and offshore cooling water pipeline. The system provides 3ppm of Hypochlorite of continuous dosing and 5ppm of shock dosing every 8 hours for 30mins. The units have a total capacity of 145kg per hour of Hypochlorite.

LOCATION:

Kavian Petrochemical Plant

DESCRIPTION:

Kavian Petrochemical plant produces two million tonnes of Ethylene per year supplying the downstream petrochemical plants. This plant required an input of 94,000 M³/h of water. This is supplied through a seawater intake system, the system required 9 automatic self-cleaning filters each with a maximum capacity of 11,000 M³/H and able to filter out particles which are over 1000 microns in size. The filters needed to have an automatic backflush mechanism in order to maintain a constant flow of water into the plant.

LOCATION:

South Pars Development 15&16

DESCRIPTION:

South pars development 15&16 has a sea water intake system supplying water to various processes and cooling systems. The scope of this project was to provide adequate filtration for some of the processes which required sea water. These filters, due to constant duty, needed to be of an automatic backflush variety to minimise down time and loss of flow. The filters were designed to filter out any coarse particle over 500 microns in size.

LOCATION:

Ahwaz, Iran

DESCRIPTION:

As a result of the increase in the salt content of the crude oil in the aging wells, it becomes necessary to implement a process to separate the salty water from the crude oil. Using flushing water and admitting crude to pass through an electro static field, the salt molecules are separated from the mixture to leave the crude with negligible salt content. Marun 2 & 6 desalting plants are located in Ahwaz, Khuzestan province, Iran.

LOCATION:

Arabian Gulf Oil Co., Libya

DESCRIPTION:

144" ID X 50'0" T/T Horizontal electrostatic Heater Treater
12 mm Btu/hr
25,000 BPD
Final assembly preformed Montreal, Quebec
Project completed May 2005, Arabian Gulf Oil Company, Libya
This unit is a comb ination of a heater and a separator, which heats the raw crude in hazardous environments, i.e. refinery, oil&gas production unit and will treat the heated oil for purification. The combined unit is well suited for hard to reach areas.

LOCATION:

Arabian Gulf Oil , Libya

DESCRIPTION:

144" ID X 70'0" T/T Horizontal electrostatic dehydrator
96" ID X 30'-0" T/T Separator
Each system utilises a horizontal electrical grid system; here a three tear grid system is utilised; live upper and lower grids and an earthed middle grid, providing a deep AC field. Crude oil is fed into the dehydrator/desalter using a specially designed distribution header which is positioned beneath the electrical grid assembly, thus ensuring even flow through the AC electrical field. Subjected to the high voltage electrostatic field, the water droplets coalesce and separate from the oil.

LOCATION:

Mahshahr, Iran

DESCRIPTION:

Two concrete cooling towers with circulating water rate of 12000 m³/hr for PVC1 and 16000 m³/hr for PVC2. The main part of the cold water flows through dual media filters to reduce the suspended solids. Chemical dosing units are considered due to the low quality of the inlet water and in order to follow the environmental safeguards various chemical treatments units have been implemented as follows:

- Sodium Hypochlorite Dosing unit
- Dispersant Dosing unit
- Biocide Dosing unit
- Sulphuric Acid Dosing unit
