I. Project Background: The Challenge of Mega-Scale
As coal-to-methanol plants scale up to the 600,000 tons/year level, the main distillation column faces unprecedented challenges. Diameters exceeding φ4000mm introduce severe fluid distribution issues. FXSINO (Pingxiang Fangxing) was commissioned to optimize the distillation system for a major energy base in Ordos, Inner Mongolia.
Certification Authority
This project was executed under our ISO 9001:2015 Quality Management and ISO 14001:2015 Environmental Management Systems.
II. Pain Point Analysis: Limitations of Conventional Design
Distributor Bottleneck: Difficulty achieving uniform liquid distribution at φ4300mm.
Inter-stage Interference: Turbulence at packing junctions disrupting mass transfer.
Stripping Section Load: High-boiling components accumulating at the base.
III. Customized Solution: Precision Internal Combinations
To maximize efficiency, FXSINO utilized 14 meters of 420X Metal Wire Gauze Packing (304 SS). With a specific surface area of 420 m2/m3, it offers superior wettability. To mitigate wall flow, we embedded 0.4~0.5m of TJH25 Sheet Metal Packing between segments.
2. Stripping Section: Hybrid Robust Design
The upper stripping section used 7 meters of Alcohol/Water Specialized Packing plus 0.8m of TJH25. Crucially, we retained 13 layers of TF3 Guided Float Valve Trays at the bottom. This leverages the design (Patent No. ZL 2005 3 0048634.6) to handle high temperatures (~120°C).

V. Conclusion & Technical Services
The success of the Inner Mongolia project proves that high-efficiency mass transfer requires a combination of advanced internals and deep process understanding. FXSINO provides turnkey solutions from simulation to installation.
"In our industry, steam consumption is everything. We were skeptical about retrofitting, but FXSINO guaranteed a drop in steam usage. Six months post-installation, the data shows a reduction of 0.07 tons per ton of methanol. That translates to millions in savings annually. The payback period was faster than expected."
