Report Abstract
This report presents the economics of spent sulfuric acid regeneration via wet sulfuric acid (WSA) process in the United States. In this process, spent acid is decomposed to form sulfur dioxide and water. The sulfur dioxide is oxidized to sulfur trioxide, which is then regenerated to sulfuric acid by vapor-phase reaction with water.
The report provides a comprehensive study of Sulfuric Acid production and related Sulfuric Acid production cost, covering three key aspects: a complete description of the Sulfuric Acid production process examined; an in-depth analysis of the related Sulfuric Acid plant capital cost (Capex); and an evaluation of the respective Sulfuric Acid plant operating costs (Opex).
The Sulfuric Acid 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 Sulfuric Acid 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 Sulfuric Acid 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 Overview

Product
Sulfuric Acid. Sulfuric acid is one of the most widely used industrial chemicals, serving as a key component in fertilizer production, mineral processing, and chemical manufacturing. It is also used in the refining of petroleum and metal ores. Sulfuric acid is produced via the contact process, where sulfur dioxide is oxidized and absorbed in water. It is stored as a liquid and is crucial for processes like phosphate fertilizer production and in lead-acid batteries.
Raw Material
Spent Sulfuric Acid. Sulfuric acid has a number of large-scale essential uses in the manufacture of other chemicals. Usually, it is employed as catalyst and, despite not being consumed in these processes, it is contaminated with impurities and becomes less effective over time. Therefore, the processes that employ sulfuric acid as catalyst require that the spent acid is replaced by strong sulfuric acid. The spent acid removed from this kind of processes is the feed for the spent acid recovery processes.
