Propylene Production from Butenes
Propylene Operating Costs & Plant Construction Costs
This report analyses the economics of Polymer Grade (PG) Propylene production from raffinate-1 in the United States, using two typical integrated processes: isomerization and metathesis. In these processes, 1-butene present in raffinate-1 is isomerized into 2-butenes. The 2-butenes are submitted with ethylene to a metathesis reaction, producing propylene. A C5s stream is generated as by-product.
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.

Products
Propylene. Propylene, the main raw material consumed, is a colorless gas at room temperature. It is a low-boiling, flammable, and highly volatile gas, with molecular formula C3H6. Propylene reacts vigorously with oxidizing materials. It may be mildly irritating to the nose, throat, and respiratory tract; propylene has low acute toxicity from inhalation. PG Propylene has been mainly produced as ethylene manufacturing co-product (via steam cracking of paraffinic hydrocarbons) and by-product of petroleum refining (separation from refinery gas). Most recently, amid a tight propylene market, new and novel lower-cost chemical processes for on-purpose propylene production have emerged.
Crude C5s. Crude C5s are a byproduct of naphtha cracking, consisting of a mixture of C5 hydrocarbons. They serve as feedstocks for the production of synthetic rubbers, resins, and adhesives. Crude C5s are separated through distillation and refining processes and are stored as liquids. They play a significant role in the chemical industry, especially in the production of high-performance elastomers.
Raw Material
Raffinate-1. Raffinate-1 is a C4 residual stream primarily consisting of isobutylene, 1-butylene, 2-butylenes, and butanes, obtained from the extraction of 1,3-butadiene from crude C4s stream, which is one of the products of the naphtha steam cracking processes.
