Paraxylene from Toluene (Conventional TDP)
p-Xylene Operating Costs & Plant Construction Costs
This report presents the economics of p-Xylene production from toluene in the United States. In this study, p-Xylene is generated via a typical toluene disproportionation process (TDP).
The report provides a comprehensive study of p-Xylene production and related p-Xylene production cost, covering three key aspects: a complete description of the p-Xylene production process examined; an in-depth analysis of the related p-Xylene plant capital cost (Capex); and an evaluation of the respective p-Xylene plant operating costs (Opex).
The p-Xylene 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 p-Xylene 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 p-Xylene 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
Paraxylene. p-Xylene, or paraxylene is the most important commercial isomer among the xylenes group. Almost all of its production is converted to Terephthalic Acid and dimethyl terephthalate. p-Xylene is primarily manufactured by naphtha catalytic reforming, followed by separation of the xylenes isomers, crystallization or absorption for p-Xylene separation.
Benzene. Benzene (C6H6) is a flammable and volatile liquid. As the most simple aromatic hydrocarbon, it is used as an intermediate to produce many important chemicals, such as styrene (raw material for polystyrene and synthetic rubber), cyclohexane (used in nylon production), alkylbenzenes (used in detergent industry), aniline (used to produce dyes and polyurethanes), and chlorobenzenes. Also, benzene is used to produce pharmaceuticals, specialty chemicals, plastics, and pesticides. It occurs naturally in crude oil and coal tar.
Raw Material
Toluene. Toluene (also known as Methylbenzene) is an aromatic hydrocarbon mainly used as an industrial feedstock and as solvent. A significant part of toluene production is blended directly into gasoline pools. Other major use of this chemical is in the manufacture of the more valuable benzene, through hydrodealkylation. Most of toluene is produced via catalytic reforming of refinery streams (C6–C9 naphthas), along with benzene, xylenes, and C9-aromatics.

Paraxylene from Mixed Xylenes (Ethylbenzene Dealkylation)
It presents the economics of a process for p-Xylene production from mixed xylenes in the United States, via isomerization followed by ethylbenzene (EB) dealkylation. In this process, a mixture of C8 aromatics is sent to an adsorption unit for the recovery of p-Xylene. The remaining xylenes are isomerized to equilibrium and the EB is dealkylated to benzene by-product.
