Diverse Tower and Internals Supply

We provide a wide range of towers and internals in materials like special alloys, ceramics, graphite, plastic, and stainless steel. Liquid distributors (orifice, trough, ladder, spray nozzle types) and gas distributor spargers are designed for uniform distribution, considering scaling/foaming factors. Packing supports, bed limiters, and mist eliminators (mesh/chevron types) are offered to enhance purity and prevent equipment damage.

Comprehensive Chemical Technology Support

With an expert team, we offer full-cycle technical support and consulting for R&D, production, process optimization, supply chain management, and environmental compliance. Services include process optimization to boost efficiency, sustainability solutions for regulatory compliance, safety risk management, IP protection strategies, and supply chain integration to reduce costs.

Innovative Energy-Saving & Intelligent Solutions

We design energy-efficient chemical plants, optimizing processes with high-efficiency heat exchangers and energy-saving pumps/fans. Intelligent solutions integrate big data, AI, and IoT for real-time process control, equipment fault prediction, and remote monitoring, enabling clients to achieve dual economic and environmental benefits.

The company provides comprehensive maintenance tips to ensure optimal performance and longevity of tower and internals systems. Regular maintenance schedules should include:
- Monthly inspections: Visual check of manway openings for corrosion, gasket degradation, and loose fasteners; ultrasonic thickness measurement of tower walls (corrosion allowance monitoring).
- Quarterly maintenance: Cleaning of liquid distributors (mechanical brushing or high-pressure water jetting, 80 - 100 bar) to remove scaling; inspection of gas distributor spargers for clogging (flow velocity verification, 10 - 15 m/s).
- Annual overhauls: Removal and detailed inspection of packing supports (crack detection via dye penetrant testing); replacement of worn mist eliminator elements (mesh density check, 100 - 200 kg/m³).
For fouling-prone services (e.g., high TAN crude distillation), consider periodic chemical cleaning (solvent flushing with inhibited acids) to reduce downtime. Thermal imaging of tower shells can detect hot spots (temperature variations > 15°C) indicating internal issues. Pressure drop monitoring (differential pressure transmitters with alarm setpoints) helps predict packing flooding or distributor blockage.

Customer Reviews

Lisa Wilson

We needed tower internals for a challenging project with frequent foaming issues. The team provided tailored liquid ladder distributors that perfectly addressed our medium-to-high flow needs in the stripper column. The pressure-driven design ensures consistent distribution, and the ceramic materials withstand corrosion flawlessly. Their expertise in process factors like scaling made all the difference.

Michael Brown

The tower internals from Changzhou Sanli Tech have transformed our packed bed operations. The liquid trough distributors efficiently handle high flow rates, and the gas spargers ensure uniform steam distribution. Made from durable stainless steel and special alloys, they resist scaling even in harsh conditions. The mesh mist eliminators have significantly improved product purity while reducing equipment damage. A reliable solution for our chemical processes!
