Crude methanol refinery technology
Proprietary Technology and Plants
Technology Introdction:
Crude methanol rectification process includes single-column process, two-column process, three -column process and energy-saving three-column process. The feature of Four processes are as follows:
No.Crude methanol rectification processFeature
1single-column process1.Methonal-water regroup, separate in one column
2.Advatange: investment saving, reduce heat energy consumption
3.Disadvantage: the purity of refined methonal is not very pure.
2two-column process1.The combination of pre-recification column and main rectification column
2.Refine crude methonol including dimethyl ether and other light components and reducing impurities
3.Advantage: simple process ,user friendly, less investment
4.Disadvange: high energy consumption, low purity
3three -column process1.Three rectification column work under the same pressure. The third rectification column produces
2.Advantage: high purity
3.Disadvantage: high investment. Need more area
4energy-saving three-column process1.Two main rectification columns and final rectification column, the first main rectification column is pressure-increasing column. The second one is normal pressure column. Two columes produce 50%-50%
2.Advantage: envery saving, reduce the ethanol content of the purified methanol, product quality is better; methanol yield is higher, low operating costs
3.Disadvantage: high one-time investment
Our company's crude methanol distillation technology is based on the fourth energy-saving three-tower process, the main feature is to fully optimize the heat transfer network, so that the use of steam and circulating water to a minimum, in order to achieve energy conservation and investment optimization.
(1) High yield of the process: fine methanol recovery rate of 99.86% (refined methanol production and feed the amount of methanol contained in the ratio)
(2) Using a mature double-effect distillation method: the use of pressurized overhead gas phase for the atmospheric tower reboiler heat source.
To 300,000 tons / year 90.82% methanol distillation as an example.

Hindalco manufactures coarse alumina hydrate, metallurgical alumina, special alumina and alumina hydrate. The chemicals business focuses on special alumina and alumina hydrates, which are products of in-house technological innovation by our Research & Development team at Hindalco Innovation Centre-Alumina(HIC-A). This research centre is recognised by the Department of Scientific & Industrial Research (DSIR), Government of India. The chemicals business serves a wide range of customers across 32 countries around the world with special alumina and alumina hydrates. Alumina hydrates find use in applications like alum, poly aluminium chloride (PAC), zeolites, aluminium fluoride, and as fire-retardant filler in polymer composites. Our special alumina finds a good suit in applications like refractory, ceramics, polishing compounds, abrasives and glass. Hindalco's captive bauxite mines in the Indian states of Maharashtra, Jharkhand, Chhattisgarh, and Odisha, supply high quality raw material to our refineries located at Belagavi in Karnataka, Muri in Jharkhand and Renukoot in Uttar Pradesh, India. The alumina refineries at Belagavi, Muri and Renukoot have installed capacities of 350,000 TPA, 450,000 TPA and 700,000 TPA respectively. The state-of-the-art alumina refinery at Belagavi is dedicated to the manufacture of special alumina and alumina hydrates. Utkal Alumina International Limited (UAIL), the fully-owned subsidiary of Hindalco Industries located in Rayagada district, Odisha, operates a most modern 2.1 MTPA alumina refinery.
