PG Propylene Production from RG Propylene
Propylene Operating Costs & Plant Construction Costs
This report examines the costs related to Polymer Grade (PG) Propylene production from refinery grade (RG) propylene, via a typical purification process. Propane stream is generated as by-product. The economic analysis performed assumes a plant located in the United States.
The report provides a comprehensive study of Propylene production and related Propylene production cost, covering three key aspects: a complete description of the Propylene production process examined; an in-depth analysis of the related Propylene plant capital cost (Capex); and an evaluation of the respective Propylene plant operating costs (Opex).
The Propylene production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Propylene plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Propylene plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

The process under analysis comprises three major sections: (1) Ethane Removal; (2) Propane Removal; and (3) Propylene Treatment.
Pre-fractionation. Refinery grade (RG) propylene is fed to a deethanizer column to reduce ethane and ethylene to less than 500 ppm mol. The ethylene/ethane stream leaving the top of this column is used as fuel, while the bottom product is sent to a propylene-propane splitter system.
Propane Removal. The deethanizer bottom stream is fed to a set of two distillation columns. In the first one, propane is withdrawn, along with most of the butylenes/butane, from the bottom and sold as by-product. The overhead stream, still containing significant amounts of propane, is sent to the second fractionator. This column acts as a continuation of the first tower, and polymer grade (PG) propylene is obtained from its top and sent a treatment step, while its bottom is pumped back to the first column.
Propylene Treatment. The PG propylene stream from the second distillation column is fed to a solid bed absorber, where water, oxygenates and sulfur are removed. It is then directed to a vessel containing catalytic adsorbent for the removal of arsine and phosphine. The purified PG propylene is sent to an intermediate tank before being directed to the downstream consumer plant, located nearby.
