Sulfuric acid (H₂SO₄) is one of the most widely produced and utilized industrial chemicals globally. It is a strong mineral acid known for its high acidity, oxidizing power, and dehydrating ability. The compound consists of hydrogen, sulfur, and oxygen and is typically produced in concentrations of ninety-three to ninety-eight percent (93–98%) or in fuming form known as oleum.
Sulfuric acid plays a critical role in numerous industries including fertilizer production, chemical manufacturing, metal processing, automotive battery production, and mineral extraction. Because of its extensive application across industrial sectors, the production level of sulfuric acid is often considered a key indicator of industrial and economic development in any country.
The production of sulfuric acid depends on raw materials that can be converted to sulfur dioxide (SO₂), which is then transformed into sulfur trioxide (SO₃) and finally absorbed to form H₂SO₄.
The main raw materials include elemental sulfur, pyrite ore, and sulfur-rich off-gases from metal smelters. Elemental sulfur is the most commonly used feedstock in modern plants due to its purity and ease of handling. Pyrite, which is iron disulfide (FeS₂), is another potential feedstock, particularly in regions where the mineral is abundant.
In some industrial setups, sulfur dioxide gases from base metal smelters such as copper or zinc plants are captured and converted into sulfuric acid, creating a beneficial integration between metal smelting and chemical production. In Nigeria, where pyrite and sulfur-bearing minerals exist, these raw materials offer potential for domestic acid production if effectively harnessed.
Modern sulfuric acid manufacturing mainly follows the Contact Process, particularly the Double Contact Double Absorption (DCDA) variant, which ensures high conversion efficiency and reduced emissions. In this process, sulfur or sulfur dioxide-rich gases are oxidized to sulfur trioxide over a catalyst such as vanadium pentoxide or platinum.
The resulting sulfur trioxide is then absorbed into existing acid or water to produce sulfuric acid. The DCDA process involves multiple catalytic passes, inter-stage cooling, and two absorption stages to maximize conversion, achieving efficiencies above ninety-nine point five percent (99.5%) while minimizing sulfur dioxide emissions. The process also incorporates extensive heat recovery systems, allowing plants to produce steam or electricity as by-products, which enhances energy efficiency.
Sulfuric acid is produced in different grades depending on end-use. The standard concentrated form, containing about ninety-three to ninety-eight percent (93–98%) acid, is the most common and is widely used in fertilizer production, metal treatment, and general industrial applications. Oleum, also known as fuming sulfuric acid, contains excess sulfur trioxide and is used for specialized applications such as nitration reactions and advanced chemical synthesis. Many plants produce oleum as an intermediate before dilution to standard acid concentration or as a finished product where industrial demand exists.
The applications of sulfuric acid are extensive and diverse. It is the primary raw material in the production of phosphate fertilizers, making agriculture its largest consumer. It is also used in the manufacture and recycling of lead-acid batteries, in the cleaning and pickling of metals, in textile dyeing, and in various chemical processes such as chlorination and alkylation. In the mining sector, it is used for ore leaching and extraction of metals.
Beyond these, sulfuric acid serves as an essential reagent in water treatment, detergents, and other industrial processes. Because of its pervasive use across multiple industries, its demand is strongly correlated with the pace of industrialization.
The global sulfuric acid market size is calculated at USD 16.83 billion in 2025 and is projected to surpass around USD 33.90 billion by 2034, expanding at a compound annual growth rate (CAGR) of eight point one percent (8.1%) from 2025 to 2034.
The market value has grown into tens of billions of dollars, and projections show continued expansion driven by fertilizer production, base metal refining, and chemical manufacturing. Asia-Pacific leads global consumption, accounting for nearly half of total demand, followed by North America and Europe. The growing agricultural and industrial base in emerging economies has made sulfuric acid a vital component of economic development.
In Nigeria, sulfuric acid is used in fertilizer manufacturing, lead-acid battery production, metal processing, textiles, and mining. Despite this high demand, domestic production remains limited. Historically, most sulfuric acid used in the country has been imported, alongside its feedstocks such as elemental sulfur. The reliance on imports adds to production costs for local industries and exposes them to foreign exchange fluctuations.
However, Nigeria’s growing fertilizer sector, expansion of the mining industry, and the increasing demand for batteries and chemicals create an opportunity for investment in local sulfuric acid production.
Nigeria has several favorable conditions for developing a sulfuric acid industry. Pyrite deposits and sulfur-bearing minerals found in several regions can serve as raw material sources. The growth of fertilizer plants, lead-acid battery manufacturers, and metal-processing facilities provides a stable domestic market. Moreover, sulfuric acid production can be integrated into mining operations or recycling plants, creating efficient industrial linkages that reduce waste and enhance value addition.
However, there are notable challenges to address. Sulfuric acid plants require significant capital investment, modern catalytic systems, and strict environmental control. Reliable access to power, raw materials, and technical expertise are also essential. Environmental and occupational safety concerns, especially regarding sulfur dioxide emissions, acid spills, and handling of corrosive materials, demand rigorous compliance with national regulations.
Nigeria’s environmental regulatory framework mandates control of emissions, safe storage, and waste treatment, which must be factored into plant design and operation.
Despite these challenges, the prospects remain positive. Rising agricultural demand for fertilizers, the push for industrial diversification, and government initiatives supporting local manufacturing all point toward a promising future for sulfuric acid production in Nigeria. The availability of local feedstocks such as pyrite and the possibility of integrating acid plants with mining or battery recycling operations present viable investment pathways. In addition, adopting modern Double Contact Double Absorption technology ensures higher efficiency, lower emissions, and competitive production costs.
Sulfuric acid production represents a strategic industrial opportunity for Nigeria. Its importance across multiple industries—from fertilizers and batteries to mining and chemicals—makes it an essential component of industrial growth. Establishing local production capacity would reduce the country’s dependence on imports, conserve foreign exchange, and stimulate backward integration in related sectors.
This report is to examine the financial viability or otherwise of establishing an automated sulphuric acid (H₂SO₄) production plant in Ebonyi State, Nigeria.
