Report Abstract
This report presents a techno-economic analysis of MTBE production from methanol and isobutylene in the Unites States. In this process, similar to UOP Ethermax process, a isobutylene-rich stream obtained from an isobutane dehydrogenation plant is etherified with methanol, producing MTBE.
The report provides a comprehensive study of MTBE production and related MTBE production cost, covering three key aspects: a complete description of the MTBE production process examined; an in-depth analysis of the related MTBE plant capital cost (Capex); and an evaluation of the respective MTBE plant operating costs (Opex).
The MTBE 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 MTBE 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 MTBE plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.
Process Schematic
The process under analysis comprises two major sections: (1) Etherification reaction; and (2) Isobutane and Methanol Recovery.
Etherification reaction. Fresh and recycled methanol reacts with the isobutylene content in the isobutylene feedstream, in liquid phase, to form MTBE. This reaction is conducted in two stages. The first stage is carried out in an adiabatic reactor at 16 bar and relatively low temperature (55°C) in order to favor thermodynamic conversion, around 90% of the isobutylene is converted in this stage. The second stage is comprised of a reaction with distillation column, in which a section of a distillation column is replaced by a catalyst packing section. This section enables the continuous removal of MTBE product from the reaction medium, making it possible to overcome the equilibrium constraints to isobutylene conversion reaching figures as high as 99%. The top product of this column, mostly composed of isobutane and the excess methanol, is transferred to the Wash Column.
Isobutane and Methanol Recovery. Initially, in a extraction column excess methanol is extracted by contact with water resulting in a methanol-water mixture and a stream containing isobutane and light end contaminants. The methanol-water mixture is distilled to recover methanol, that is recycled to compose the feed stream of the first reactor. The hydrocarbons stream from the Wash Column is then introduced into a depropanizer column to eliminate light end impurities (C3- products). These light ends are consumed in the process as fuel, while the C4s by-products stream, composed mainly by isobutane, is directed to the integrated unit.
