Turnkey EPC Delivery for a High-Performance Sulfonation Plant in Latin America
On August 24, 2026, Beijing ZJS Fine Chemical Technology Co., Ltd. successfully completed the initial commissioning of a 3.8 t/h sulfonation plant in Peru, delivered under a complete Turnkey EPC (Engineering, Procurement and Construction) model.

From process design and equipment procurement to installation, commissioning, and operational support, ZJS provided comprehensive project services throughout the entire lifecycle. The successful first-time commissioning marks another important milestone in ZJS’s international expansion and demonstrates the company’s capability to deliver advanced sulfonation technology and turnkey chemical plants to the Latin American market.
During the commissioning process, the entire production line operated smoothly and successfully produced qualified products. The project team overcame challenges involving international supply-chain coordination, on-site construction management, cross-cultural communication, and local compliance requirements.
The completed facility provides the customer with a highly automated, ready-to-operate LABSA production line, helping meet the growing demand for high-quality detergent raw materials in Peru and neighboring Latin American markets.
Excellent Test Results: High Active Matter and Ultra-Low Color
During continuous trial operation, the plant utilized ZJS’s Third-Generation Film Sulfonation Reactor together with a series of advanced process and control technologies.
On-site sampling and testing demonstrated excellent equipment stability, automation performance, reaction control, and product quality. The key product indicators exceeded the reference standards for premium-grade products.

96.92% Active Matter
The measured active matter content reached 96.92%, exceeding the premium industry reference standard of ≥96.5%.
High active matter means a higher concentration of effective surfactant, which can help improve formulation efficiency and provide greater flexibility for downstream manufacturers of liquid detergents, laundry detergents, dishwashing products, and other cleaning formulations.
Ultra-Low Color: Only 5 Klett
The product achieved a color value as low as 5 Klett, significantly better than the typical premium-grade reference range of approximately 15–20 Klett.
The exceptionally low color indicates a highly refined product with excellent appearance quality, making it particularly valuable for downstream applications where product appearance and formulation quality are important.
Low Free Oil: 1.10%
Another key performance indicator was free oil, which was controlled at only 1.10%, compared with the premium-grade reference limit of ≤1.50%.
This result demonstrates highly efficient conversion of linear alkylbenzene (LAB) during the sulfonation process and reflects the excellent reaction performance of the ZJS sulfonation system.
Low Free Acid: 1.39%
The measured free acid content was 1.39%, also below the premium-grade reference limit of ≤1.50%.
The result further validates the performance of ZJS’s Third-Generation Film Sulfonation Reactor in terms of manufacturing precision, cooling efficiency, organic-material distribution accuracy, and reaction control.
By improving the precision of material distribution and reaction conditions, the reactor helps reduce unwanted side reactions while also minimizing the potential risk of equipment corrosion.
Key Product Performance
| Quality Indicator | Measured Result | Premium-Grade Reference |
|---|---|---|
| Active Matter | 96.92% | ≥96.5% |
| Color | 5 Klett | Approx. 15–20 Klett |
| Free Oil | 1.10% | ≤1.50% |
| Free Acid | 1.39% | ≤1.50% |
These results demonstrate the ability of the 3.8 t/h sulfonation plant to achieve a combination of high active matter, low color, low free oil, and low free acid under continuous operating conditions.
