As industrial processing requirements in the Middle East demand unprecedented levels of thermal efficiency and corrosion resistance, Nordstone has established itself as one of the premier stripper column manufacturers in UAE.
Leveraging over 20 years of precision engineering experience, we design and manufacture heavy-duty column internals and gas-stripping systems tailored for the region’s intense Oil & Gas, petrochemical, and chemical processing sectors. Whether your operations require automated steam stripping units, hydrocarbon fractional distillation components, or high-pressure sour gas treatment columns, our facility delivers custom-engineered solutions capable of withstanding extreme pressures, toxic $H_2S$ environments, and soaring ambient temperatures.
Every vessel is manufactured in strict compliance with international safety protocols, incorporating advanced metallurgy like Duplex steel, Inconel cladding, and specialized industrial coatings.
Partner with a veteran manufacturing leader to optimize your mass transfer efficiency and minimize downstream volatile organic compound (VOC) emissions.

Technical FAQs: Stripper Column Manufacturing & Design
1. What materials of construction (MOC) does Nordstone use for manufacturing stripper columns in the UAE?
We select materials based on the specific chemical components, operating temperatures, and corrosivity of your process stream. Typically, we use high-grade Carbon Steel (with or without corrosion allowances), Stainless Steel (304L, 316L) for general chemical resistance, and advanced Alloys like Duplex 2205, Super Duplex, or Inconel cladding for highly corrosive environments involving sour gas (H2S) and high chloride concentrations common in UAE coastal regions.
2. Can Nordstone manufacture columns that meet ASME Section VIII, Division 1 and 2 standards?
Yes. Backed by our 20 years of industrial engineering experience, Nordstone specializes in custom pressure vessel fabrication adhering strictly to ASME Section VIII (Div 1 & 2) codes. This ensures that every stripper column can safely manage extreme structural loads and high internal design pressures.
3. What specific stripping mechanisms do your columns support?
Our custom-engineered columns are designed for a variety of critical separation processes, including:
- Steam Stripping: For removing volatile organics or hydrocarbons from wastewater streams.
- Air/Gas Stripping: Utilizing nitrogen or air to remove dissolved gases like carbon dioxide (CO2) or hydrogen sulfide (H2S).
- Reboiled Stripping: Implementing a bottom reboiler configuration for sharp fractional distillation profiles.
4. How does Nordstone optimize mass transfer efficiency inside the stripper columns?
Our engineering team utilizes advanced hydraulic modeling to customize column internals. Depending on your pressure drop limitations, foaming tendencies, and turn-down requirements, we equip columns with high-efficiency structured packing, random packing (such as pall rings or saddles), or custom-engineered valve/sieve trays to ensure maximum gas-liquid contact area.
5. Do you provide localized engineering support and maintenance across the UAE?
Yes. While our state-of-the-art manufacturing hub handles heavy fabrication, our field engineering team provides localized support across all emirates (Abu Dhabi, Dubai, Sharjah, etc.). This includes site testing, installation guidance, internal modifications, and emergency shut-down maintenance.
6. What quality control and non-destructive testing (NDT) protocols do you implement?
Every industrial vessel undergoes rigorous quality inspection before leaving our facility. Our internal QA framework includes:
- Radiographic Testing (RT) for weld integrity.
- Ultrasonic Testing (UT) and Magnetic Particle Testing (MT).
- Hydrostatic Pressure Testing to confirm physical design compliance.
- Positive Material Identification (PMI) to verify alloy composition.
7. Can your columns handle the sour gas environments common to UAE Oil & Gas fields?
Absolutely. Nordstone designs columns specifically compliant with NACE MR0175/ISO 15156 standards for sulfide stress cracking (SSC) and stress corrosion cracking (SCC) resistance. We use HIC (Hydrogen-Induced Cracking) resistant steels and post-weld heat treatment (PWHT) to eliminate structural vulnerability in sour environments.
8. What is the typical lead time for a custom-built stripper column?
Lead times vary depending on column diameter, height, material availability (especially for exotic alloys), and design complexity. Generally, custom engineering, detailing, procurement, manufacturing, and testing span from 16 to 26 weeks. For precise lead times on a current project, please submit your data sheet on our Contact Us page.
9. Do your designs account for the extreme environmental conditions of the Middle East?
Yes, all external mechanical designs calculate wind loading and seismic criteria specific to the UAE region, alongside severe ambient thermal expansion factoring. We apply specialized UV-resistant and high-temperature external industrial coatings to protect against marine atmospheric corrosion and sand abrasion.
10. What certifications does Nordstone hold?
Our commitment to international safety and quality standards is verified by our multi-decade industry track record and our alignment with API (American Petroleum Institute), ASME (U, UM, R stamps), and ISO 9001:2015 quality management systems.
11. Can you retrofit or debottleneck an existing stripper column onshore or offshore?
Yes. Our engineers can assess your current column internals, run process simulations based on updated feed variables, and manufacture higher-capacity trays or structured packing to dramatically improve your mass transfer output without requiring the cost or space of a completely new shell installation.
12. How do you prevent foaming issues within the stripping process?
Foaming can drastically reduce column efficiency and cause liquid carryover. We design specialized feed inlets and liquid distributors to minimize turbulence, adjust downcomer areas on tray designs, and when necessary, optimize the packing depth to handle foam-prone chemical streams effectively.
13. What options do you offer for column internals and liquid distributors?
We manufacture a wide range of proprietary and standard internals, including gravity-trough distributors, pressurized pipe lateral distributors, bed limiters, packing support plates, and multi-beam support grids, all structurally verified to withstand heavy liquid holdup.
14. Is thermal insulation provided with the column fabrication?
We engineer and install insulation support rings directly onto the vessel shell during the manufacturing phase. We can supply complete thermal insulation systems (such as mineral wool or calcium silicate with aluminum cladding) tailored to maintain high internal process stripping temperatures and ensure personnel safety on-site.
15. How do I initiate a request for quotation (RFQ) with Nordstone?
To receive a detailed technical proposal, you can share your process conditions—including feed flow rates, operating temperature/pressure parameters, required separation efficiency, and material preferences—directly with our engineering sales unit via our Contact Us portal.
