Sulphonic acid equipment
We provide integrated engineering solutions for Sulphonic acid equipment, from process design and equipment manufacturing to installation support and commissioning.
The plant can be configured for LABSA, AOS, fatty alcohol derivatives, and other sulfonated products, depending on the customer's production requirements.
Complete Plant Configuration
A typical project may include the following systems:
SO₃ Generation Unit
This section converts sulfur into sulfur trioxide through controlled combustion and catalytic oxidation.
Air Treatment System
Dry and clean process air is essential for stable sulfonation. The air treatment section can include filtration, drying, cooling, and flow-control equipment.
Organic Feed System
The organic raw material is stored, filtered, heated, metered, and delivered to the sulfonation reactor at a controlled flow rate.
Sulfonation Reactor
A falling film sulfonator provides continuous contact between the organic feed and SO₃ gas, enabling rapid and controlled sulfonation.
Product Treatment
Depending on the final product, the system can include aging, hydrolysis, dilution, neutralization, cooling, and storage.
Tail Gas Treatment
Unreacted SO₃ and acidic gases are treated through an appropriate absorption or scrubbing system before discharge.
Engineering Scope
Our project services can include:
Process Design → Equipment Design → Detailed Engineering → Manufacturing → Factory Inspection → Shipment → Installation Guidance → Commissioning → Operator Training
We can also integrate the sulfonation plant with existing detergent powder, liquid detergent, or downstream chemical production facilities.
Customized Solutions
Sulphonic acid equipment design can be adjusted according to:
- Product type
- Production capacity
- Raw material
- Required product concentration
- SO₃/organic feed ratio
- Utility conditions
- Factory layout
- Environmental requirements
- Automation level
Whether it is a new production facility, capacity expansion, or modernization project, we can develop an integrated SO₃ sulfonation solution based on the customer's specific requirements.
