Forouz B Gas Field Development Project

The Forouz B Gas Field Development Project is a significant offshore and onshore energy initiative led by MAPNA Oil and Gas Development Company, operating as the Buy Back Contractor for the Iranian Offshore Oil Company. The primary goal is to produce and process 1000 MMSCFD (million standard cubic feet per day) of natural gas, with onshore processing facilities strategically located on Qeshm Island, approximately 180 kilometers from the offshore production installations in the Persian Gulf.

The project is designed to maximize the recovery of valuable C3+ components, including propane, butane, and natural gasoline, as well as sulfur, while delivering lean gas at the battery limit for export or further use. This ensures efficient resource utilization, greater product flexibility, and increased economic value for Iran’s energy sector.

Project Scope and Objectives

Maximize C3+ Recovery: The plant is designed to optimize extraction of propane, butane, natural gasoline, and other heavy hydrocarbons for saleable product streams.
Produce Multiple Products: Final outputs include lean gas, propane, butane, natural gasoline, and recovered sulfur—each meeting strict quality and export standards.
End-to-End Processing: Project scope covers the full design, construction, and integration of all processing units, utilities, off-site facilities, and supporting infrastructure on Qeshm Island.

Tehran Raymand’s Role and Project Responsibilities

Conceptualization of plant configuration and production flows.
Basic design of processing units, utility systems, and plant infrastructure.
Front-End Engineering Design (FEED) for all plant components and interfaces.
Preparation of EPC tender documents to support contractor selection and project execution.
Timeline: All engineering, FEED, and documentation completed within 12 months.

Plant Components and Processing Units

Unit-100: Reception Facilities – Receives and conditions gas from offshore installations for downstream processing.
Unit-101: Gas Sweetening Unit – Removes H₂S and CO₂ from the raw gas stream for safety and environmental compliance.
Unit-102: Glycol Regeneration (MEG) and Injection – Regenerates monoethylene glycol and injects it into the gas stream to prevent hydrate formation, protecting pipelines and processing equipment.
Unit-103: Condensate Stabilization Unit – Stabilizes hydrocarbon condensate for safe storage and transportation.
Unit-104: Gas Dehydration / Mercury Removal Unit – Removes water vapor and mercury to ensure product quality and process safety.
Unit-105: LPG Extraction Unit – Separates liquefied petroleum gas (LPG) from the treated gas stream.
Unit-106: Export Gas Compression Unit – Compresses lean gas for export or transfer to downstream users.
Unit-107: LPG Fractionation Unit – Further fractionates LPG into individual components such as propane and butane.
Unit-108: Sulfur Recovery Unit – Recovers elemental sulfur from the gas, supporting environmental sustainability.
Unit-109: Sour Water Stripping Unit – Treats sour water to remove dissolved gases and contaminants.
Unit-110: Condensate Back-up Stabilization Unit – Provides redundancy and additional stabilization for hydrocarbon condensate.
Unit-111: Propane Refrigeration Unit – Provides low-temperature refrigeration for propane storage and export.
Unit-113: C3/C4 Caustic Regeneration Unit – Regenerates caustic solution used in propane and butane purification processes.
Unit-114: Propane Treatment and Drying Unit – Final treatment and drying of propane for storage and export.
Unit-115: Butane Treatment and Drying Unit – Final treatment and drying of butane for export readiness.
Unit-143: Condensate Storage and Export – Secure storage and management of stabilized condensate prior to shipment.
Unit-144: Sulfur Storage and Solidification – Storage and solidification of recovered sulfur for safe handling and export.
Unit-147: Propane Storage and Export – Facilities for safe, efficient storage and loading of propane.
Utility Facilities: Comprehensive utility systems including power supply, water, steam, instrumentation, fire protection, and plant support systems for all units.

The integrated design and advanced technology of the Forouz B Gas Field Development Project will enable Iran to increase its production of clean, saleable energy products, support regional energy demands, and improve overall value chain efficiency in the oil and gas sector.
