How much investment does it cost to build a new 100,000 cubic meters of hydrogen per hour?
Thread Content
Buy oxygen and nitrogen from outside (that is, you do not build an air separation unit yourself), and completely build a new set of 100KNM3/h hydrogen. The gasification uses GE coal-water slurry gasification, the pressure is 6.5Mpa, the desulfurization and decarbonization use low-temperature methanol washing, and finally methanation is used to remove CO from the hydrogen. How much does it cost to build such a device now? This post was last edited by lkx646 on 2008-3-5 19:30 ]
I happen to have a similar device on hand. According to the current price level, it should be 1.8-2 billion yuan.
The second floor is a bit high. Your investment should include air separation and thermal power. If it is just gasification and purification, it will be about 1.1 billion. This is the actual value of a project currently under construction.
reply: 1. This is related to the system configuration (system series settings). 2. 100kNM3/h hydrogen, calculated based on 80% effective gas (CO+H2) content in GE coal-water slurry gas (actual production is 82-83%), approximately requires 125kN3/h effective gas (CO will be converted into H2 in the conversion section). 3. According to the effective gas volume of 125kN3/h, two DN3200mmGE coal-water slurry gasifiers (operating pressure 6.5MPa) are required to provide gas. 4. Considering the continuous operation cycle of the GE coal-water slurry gasifier, a backup furnace may be needed, and daily production is carried out in a two-on-one-backup operation. 5. According to personal knowledge and the construction content mentioned by the poster, the project investment is: ·1.3 billion yuan------install two gasification furnaces, no furnace preparation. 1.9 billion yuan------ install three furnaces, open two gasifiers and prepare one. The above opinions are for reference.
I agree with the point above, the price is probably this at the moment. If you have the money, it is better to buy two open and one prepared, it is more reliable. Although the GE one is more reliable than the SHELL one at present, but it is better to be prepared. :lol
:lol Oh, we have also graduated from the first grade, so I am very excited. :victory: Thank you liuze78 for the reminder and everyone’s generous contribution. Thank you. :handshake
The investment in the gasifier upstairs is too high. Ours is 6.5MPa, 2+1 mode, conversion, low-temperature methanol washing, methanation, and equipped with 45,000 air separation, 3* 210 ton boiler and 3 * The total investment for a 25MW turbine generator is only over 2.1 billion. The current investment in the GE gasification island with a coal capacity of 3,000 tons is only 350 million yuan. ； Other: Two 2800 GE gasifiers with 100,000 cubic meters of hydrogen are enough (6.5MPa gasification pressure), and the coal input per unit is about 750~800 tons. ； This post was last edited by yanghq on 2008-3-10 09:08 ]
is the current price. At present, the project has basically been completed and has entered the "three checks and four determinations" phase. The construction period of the project began in 2005. The peak equipment procurement period for the boiler part was from the end of 2005 to the end of 2006, and the peak equipment procurement period for the gasification part was from mid-2006 to the end of 2007. The total investment must exceed 2.1 billion, but it will not exceed too much. It is estimated that 2.3 billion can be obtained. The purchasing specifications of the equipment are relatively high, and the domestic equipment is all first-class equipment. There is no land acquisition cost for the entire project. Just to add: 1. The gasifier with an inner diameter of 2800mm may seem a bit too small at present, and the potential for overloading of the gasifier may be basically gone. 2. The operating mode of the gasifier with two openings and one standby is very necessary. 3. It is correct to choose the 1-to-1 model for the gray water treatment system. Although the investment in pipelines and valves has increased a lot, it will create great convenience for future operations. 4. The selection of gasification pressure needs to be discussed. If there are no strict pressure requirements downstream, I personally tend to choose three gasifiers with a diameter of 3200mm and a gasification pressure of 4.0Mpa. Under low pressure, the investment in pipelines, valves, flanges, instruments, etc. of the entire system should decrease significantly.
What is the approximate cost of hydrogen for this kind of hydrogen production device?
What are the supporting public works?
