Questions regarding gasifier investment
Thread Content
Could some kind person tell me: taking an entire gasification island for a methanol plant with a capacity of 600,000 tons per year as an example, what would be the approximate investment costs if Texaco, Shell, GSP, four-nozzle, and multi-material slurry technologies were used?

I hope everyone will speak up actively, so that we can all gather useful data to assist in investment decisions
It’s best to ask the design institute for the data on this issue.
Texaco: 600 million; Shell: 750 million; GSP: 650 million; Four-nozzle: 650 million; Multi-material slurry technology: 600 million
Are you referring to just the furnace itself, or the entire project? Our factory has currently invested 1.2 billion yuan, but it still isn’t fully equipped for production!
It’s just the vaporization furnace; if all the accompanying components are included, the cost is estimated to be 3.5 billion
It refers to the entire gasification island, including the gasifier, powder or pulp production systems, ash and water treatment systems, etc
The year before last, investigations and comparisons were conducted specifically on the four-nozzle technology and GE technology; however, steel prices were not as high back then. I’m not very familiar with the current market situation. Based on the conditions in August of last year, the investment costs for these gasification projects (including coal slurry preparation, gasification, and ash water treatment) are roughly as follows: Texaco: 900 million; Shell: 1 billion; GSP: 900 million; four-nozzle technology: 900 million; multi-material slurry technology: 800 million. The patent costs for the four-nozzle technology and multi-material slurry technology are low, but for 60WT methanol production, the coal grinding machines and ash water treatment systems required are one-to-one in quantity, which results in higher hardware investment costs.
For the 600,000 tons per year methanol production project, whose construction started in 2007 and continued until the previous year of 2009, the investment in the gasification unit was as follows: Texaco – 540 million; Four-nozzle type – 600 million; Multi-material slurry type – 520 million; Shell – 850 million (with a backup furnace)
Why is there such a big difference in the data?
