The largest sulfur producer group in Kazakhstan has officially put into operation a 40-square-meter fully automatic Leaf filtration system designed and manufactured by our company at its refinery. This equipment will be used in the final fine filtration process of high-purity sulfur, marking a new stage of intelligence in sulfur processing technology in Central Asia.

Project Background

As one of the world's top ten sulfur suppliers, the group's original filtration system is confronted with:

• Low filtration efficiency (single processing time exceeds 8 hours)

• Unstable product purity (with large fluctuations in impurity content)

• High risk of manual operation (danger of contact with high-temperature sulfur)

Customized solutions

Our technical team has developed a special filtration system based on the characteristics of sulfur

Core configuration

Double cylinder structure: Inner cylinder SS316 (6mm)/outer cylinder SS304 (4mm)

50mm thickened insulation jacket (for maintaining 180℃ operating conditions)

15 groups of SS316 filter elements (accuracy 25μm)

Siemens fully automatic control system

Hydraulic-driven unloading device

The person in charge of the company stated, "Its design pressure of 1.0MPa has increased the filtration efficiency by 300%, while maintaining the product purity above 99.98%."

Highlights of technological innovation

Special sealing system: Made of polytetrafluoroethylene, it is resistant to sulfur corrosion

Intelligent reverse blowing function: Automatically clean the filter elements to extend service life

Three-stage temperature control: The jacket layer precisely maintains the process temperature

Intrinsic safety design: DN20 pressure relief port + explosion-proof electrical components
