Overview
Usage of Large-Scale Industrial Process Columns and Our Manufacturing Capabilities
Large-scale industrial process columns are critical components in numerous process-driven industries where separation, purification, absorption, or chemical reaction is required. These vertical vessels—often towering in size—are engineered to handle complex physical and chemical processes under varying conditions of temperature and pressure. Our company is a trusted manufacturer of industrial process columns, offering end-to-end solutions from design and fabrication to testing and site support. With world-class manufacturing infrastructure and engineering expertise, we deliver high-performance columns tailored to the most demanding industrial environments.
Oil & Gas Refining
- Distillation columns are central to separating crude oil into valuable fractions like gasoline, diesel, naphtha, and kerosene.
- Absorber and stripper columns are used in gas sweetening (e.g., amine treatment) and dehydration units.
- Designed to operate under high pressure and temperatures with corrosive hydrocarbons.
Petrochemical & Chemical Processing
- Used in separation and purification of chemical mixtures through distillation, extraction, rectification, and absorption.
- Tailored for continuous or batch operations, often incorporating internal components like trays, packing, and distributors.
- Materials selected to withstand acids, solvents, and highly reactive media.
Fertilizer and Ammonia Plants
- Reactor columns, synthesis towers, and urea strippers are key units in ammonia and urea production.
- Precision-designed for mass transfer and reaction kinetics under high pressures and catalytic conditions.
Pharmaceutical & Fine Chemicals
- Utilized for high-purity separation and solvent recovery with strict GMP compliance.
- Built with hygienic design principles and high-grade stainless steel for clean-in-place (CIP) compatibility.
Environmental & Gas Processing
- Packed and tray columns are deployed in CO₂ capture, gas drying, and emission treatment.
- Engineered to handle variable loads and corrosive off-gas components.
