1-Butene Production from Ethylene
Butene Operating Costs & Plant Construction Costs
This study presents the costs associated with the construction of an industrial plant producing 1-Butene from ethylene in the United States. This study analyzes a process similar to the Axens/SABIC AlphaButol technology. In the process under analysis, ethylene is dimerized into butenes with high selectivity for 1-Butene. Gasoline (C6+ stream) is generated as by-product.
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.

The process under analysis comprises the following major sections: (1) dimerization; and (2) separation & purification.
* Dimerization. Initially, fresh ethylene and recycled ethylene are fed to the dimerization reactor, along with catalyst and co-catalyst diluted in butene. The dimerization occurs in the liquid phase, at mild conditions. Reaction heat is continuously removed by means of an external cooler. The reactor effluent, containing the 1-Butene produced, is routed to separation steps downstream.
* Separation & purification. This section comprises essentially separation and purification steps for isolating the 1-Butene produced. The dimerization reactor effluent is initially passed through a flash vessel and then through evaporators, in such a way that most of the hydrocarbons in that stream vaporize and spent catalyst is discharged. The gaseous streams are combined, liquified and passed through a distillation column, in which ethylene is separated and recycled to dimerization. Finally, in a last distillation step, 1-Butene with a purity of 99.5 wt % is separated from residual oligomers.
