Which tray type should I choose for my distillation column?

Sieve trays suit clean services with steady loads at the lowest cost. Fixed valve trays add fouling resistance and better turndown. Floating valve trays handle wide load variations with high efficiency. Bubble cap trays are used where very low liquid rates or positive liquid sealing are required. Our engineers recommend a tray type after reviewing your vapor and liquid loads, operating pressure and fouling tendency.

When is structured packing better than trays?

Structured packing is generally preferred for vacuum distillation, heat-sensitive products and revamps that need more capacity or efficiency within the same shell, because it offers a much lower pressure drop per theoretical stage than trays.

What materials do you manufacture column internals and wire mesh in?

Standard materials include stainless steel 304, 304L, 316 and 316L. Wire mesh is also produced in Hastelloy, Monel, Inconel, nickel, titanium, copper, brass and phosphor bronze. Other alloys can be supplied to project specification.

Do you export to buyers outside India?

Yes. Ambani Metals exports to more than 20 countries including the UAE, USA, Australia, Canada and the wider Gulf region, with export packing and shipping documentation prepared for each order.

What information is needed for an accurate quotation?

Share the column diameter, number of trays or packed bed height, material of construction, design pressure and temperature, process data sheet or drawings, required quantity and delivery destination. For wire mesh, provide alloy, mesh count, wire diameter, weave type and roll or panel size.

Frequently Asked Questions (FAQ)

1. What are the key industrial applications for wire gauze structured packing?

Wire gauze structured packing is widely deployed in fine chemical, air separation, petrochemical, and pharmaceutical industries where low pressure drop and high separation efficiency are critical, particularly during vacuum distillation, stripping, and absorption processes.

2. How do ST-CY and ST-BX structured packings differ?

ST-CY provides a higher specific surface area (700 m²/m³) and more theoretical plates (4-6 per meter), making it ideal for systems requiring stringent separation precision. ST-BX features a higher void percentage (95%) and lower pressure drop (1.5 mmHg/m), which delivers higher capacity and larger gas/liquid throughput.

3. Can you assist with column hydraulic calculations and engineering design?

Yes, our pre-sales technical team provides chemical process simulation, comprehensive hydraulic calculation, revamping designs, and custom engineering drawings tailored to your specific mass transfer challenges.

4. Do you support international on-site installation and commissioning?

Yes, STT provides global engineering support. Qualified engineers can be dispatched overseas to oversee installation, conduct commissioning, provide operational guidance, and offer on-site failure troubleshooting.

5. What international quality verifications and standards do your products satisfy?

All materials undergo rigorous chemical and mechanical material testing before shipment. We have successfully completed factory acceptance tests for prominent multinational corporations, including Alfa Laval, Mitsubishi, Perstorp Formox, and Air Liquide.
