1-Butene from Raffinate-2 (Hydrogenation Followed by Fractionation)
Butene Operating Costs & Plant Construction Costs
This feasibility study concers 1-Butene production from raffinate-2. In this study, raffinate-2 is first subjected to a hydrogenation step before fractionation. Raffinate-3 is generated as by-product. The economic analysis is also based on a plant located in the United States.
The report provides a comprehensive study of Butene production and related Butene production cost, covering three key aspects: a complete description of the Butene production process examined; an in-depth analysis of the related Butene plant capital cost (Capex); and an evaluation of the respective Butene plant operating costs (Opex).
The Butene 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 Butene 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 Butene 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
1-Butene. 1-butene, cis-2-butene, trans-2-butene, isobutylene and butadiene are usually coproduced as a mixture - referred to as C4 fraction - from petroleum refinery/petrochemical process. Typically, for obtaining pure 1-butene, C4 fraction is sent a selective extraction of isobutylene with sulfuric acid, butadiene selective hydrogenation and distillation for 2-butenes separation. An alternative means of producing 1-butene is the ethylene dimerization. Butenes are mainly used as alkylate and polymer gasoline, in fuel applications, and as co-monomers in the production of some polymers. 1-butene, particularly, is mostly used as a comonomer for LLDPE production, and as a comonomer for modifying high density polyethylene (HDPE).
Raffinate-3. Raffinate-3 is a byproduct of butadiene extraction from C4 streams, rich in butenes and used as a petrochemical feedstock. It is utilized in alkylation units to produce high-octane gasoline components. Collected during olefin separation processes, it is stored as a liquefied gas. Its composition makes it valuable for further processing into chemicals like MTBE and isobutylene derivatives.
Raw Material
Raffinate-2. Raffinate-2 is a C4 residual stream primarily consisting of 1-butene, 2-butenes, and butanes. It is obtained following the separation of 1,3-butadiene and isobutylene from mixed C4s stream (or crude C4s), which is one of the products of the naphtha steam cracking processes.
