Razi Purge Gas Recovery Unit

Project Description:

Razi petrochemical complex has decided to boost Ammonia production in Razi No1 and/or No 2 Ammonia plants by incorporating of hydrogen recovery from synthesis purge stream The target is to recover as much as possible of Hydrogen and Ammonia contents from synthesis purge gas which is venting or injecting to furnace fuel at present Recovered Hydrogen will be returned to synthesis loop and mixed with synthesis makes up gas Increased capacity will require additional process air Extra process air could be supplied by adding a common parallel air compressor for both plants

The plant consists of the following process units:

• Pretreatment Unit.
• Membrane Recovery Package.
• Process Air Compressor.

Scope of Work:

• Feasibility Study of the project based on the existing plants process information and find out the optimum process design.
• Preparation and delivery of the basic engineering package.
• Performing detail engineering and preparation of tender documents for construction and installation works at site.
• Supply and delivery of materials including all mechanical equipment and.
• electrical/instrumental devices, commissioning and operating spares.
• Performing the technical services and supervision.
