The company delivers comprehensive solutions for methanol plants, combining advanced technology with operational excellence. For natural gas-based plants, the process includes steam methane reforming (SMR) with secondary reforming for H₂/CO ratio adjustment, followed by methanol synthesis in tubular fixed-bed reactors (catalyst: Cu-Zn-Al, temperature 220 - 260°C, pressure 50 - 100 bar). Coal-based plants utilize gasification (entrained flow or fixed bed) to produce syngas, with acid gas removal (Rectisol or Selexol) before methanol synthesis. Plant capacities range from 500 to 5,000 tons per day, with energy consumption as low as 28 GJ/ton of methanol through advanced heat integration. Methanol purification systems use distillation with dividing wall columns to separate methanol from water and higher alcohols, achieving purity > 99.99%. The company also offers methanol plant revamping services, such as converting single-stage reactors to multi-stage with interstage cooling, increasing capacity by 20 - 30% while improving catalyst life (from 12 to 18 months).
