Product details
Product Line Basic Information
Our sulfur trioxide SO₃ production line is a complete industrial plant unit for manufacturing sulfur trioxide. The full‑set system includes sulfur melting & filtration, sulfur burning, heat recovery system, catalytic conversion, absorption unit, cooling & condensation, finished product collection, tail‑gas treatment and auxiliary modules. We support customized capacity from small pilot‑scale plant to large‑tonnage commercial production plant. Adopt mature sulfur‑burning catalytic oxidation process according to customers’ raw material and utility conditions to realize continuous automatic production. All equipment meets strict chemical industry safety, anti‑corrosion and environmental protection standards, suitable for new‑built factory construction, old‑plant renovation and capacity expansion projects.
Core Advantages of Production Line
- Customized process solution: Optimize technical flow according to client’s sulfur raw material quality and local utility conditions to cut comprehensive production cost.
- High automation level: Realize automatic feeding, temperature and pressure closed‑loop control, reduce manual intervention, stable SO₃ product concentration and quality.
- High‑efficiency energy recovery: Multi‑stage waste heat recovery system generates steam, improves overall energy utilization rate of the whole plant.
- Reliable anti‑corrosion design: Key reaction and absorption sections adopt anti‑corrosion material configuration, extend equipment service life.
- Complete tail‑gas treatment system: Strict tail‑gas purification device to satisfy local environmental emission requirements.
- Modular equipment layout & rich overseas EPC experience: Shorten site installation cycle, convenient for maintenance and spare‑parts replacement. We own abundant practical experience in sulfur‑based chemical plant projects for global customers.
Main Applications of Sulfur Trioxide
- Sulfonation industry: Core raw material for sulfonation reaction, widely used in detergent raw material production.
- Chemical manufacturing: Used for producing concentrated sulfuric acid, oleum and other sulfur‑series chemical products.
- Fine chemical field: Applied in synthesis of dyes, surfactants, pharmaceutical intermediates.
- Other industries: Used in petrochemical processing and inorganic salt production processes.
