How much investment is required for a 30,000-ton sulfuric acid plant?
Thread Content
There is currently a 30,000-ton sulfuric acid production plant, and the flue gas is relatively clean; a cooling tower is sufficient for purification. What is the required investment? SO2 CO2 H2O O2 6.77 14.87 6.82 6.77 Flue gas volume: 11962 Nm3/h
You can estimate the following: without a furnace or electric dust collector, with two rotations and two suction cycles, 15 million should be sufficient! This post was last edited by Peach blossoms are in bloom on 2009-2-9 18:19.]
For reference, in Yunnan, for a single plant producing 40,000 tons of sulfuric acid, the simplest and most cost-effective approach would result in an investment of 24 million. After it was done, we all found it incredible. At the current price, it should be not much different. Without electric dust, electric fog, and intercoolers, around 4 million can be saved.
Yeah, it’s around 25 million or so
Thank you all! Since the impurity content in the flue gas is very low, a cooling tower is sufficient for purification; my initial estimate was around 20 million.
It won’t exceed 15 million. My estimate is as follows: Conversion: 4.5 million (of which, heat exchangers account for 900,000; catalysts account for around 400,000–500,000; converters account for 1.47 million). Dry absorption: 3–3.5 million (of which, dry absorption towers account for 500,000–600,000 per unit, times 3). Civil engineering work: 2 million. Electrical equipment and instruments: 1.5 million.

The total cost is estimated to be around 21 million yuan, especially given the significant drop in raw material prices at present. The question is, should the 30,000-ton sulfuric acid project still be launched?
The factors affecting the investment in acid production systems include, in addition to the main process flow, the equipment and level of automatic control available in the system, as well as the requirements for inspection, shutdown, and maintenance. The quality of the equipment affects the type of materials used; the cost of automatic control systems is primarily related to the instruments used for monitoring and control. Even when all components are domestically produced, there can still be differences in cost-effectiveness. Additionally, it is necessary to consider whether an exhaust chimney is required, as this also represents a significant investment. The entire setup is estimated to cost around 20 million
The 30,000 tons mentioned by the poster refers to flue gas that contains CO2 in relatively high concentrations; however, the process is quite clean. It seems to be a flue gas recovery-based acid production method, and such projects **should be permitted**. The restrictions apply to sulfur-based acid production facilities with a capacity of less than 200,000 tons per year, as well as pyrite-based acid production facilities with a capacity of less than 100,000 tons per year – not to all sulfuric acid production projects with a capacity of less than 30,000 tons
