Where is the investment in ammonia recovery mainly focused? How much would it cost to produce 120,000 tons of synthetic ammonia?
It mainly involves high-pressure water pumps and polymer fiber membranes, as well as ammonia washing towers and separators. For 120,000 tons of synthetic ammonia, that’s over 2 million. It depends on which company you choose; I can give you their contact information for you to get in touch
Okay, thank you. By the way, what is the system pressure? Is there a simple introduction to the manufacturing process?
The previous model of passive ammonia recovery is cost-effective, operates smoothly, is easy to handle, and saves steam; it is very popular at present.
The main manufacturers of passive ammonia recovery units do not mention hydrogen recovery any further, as the ammonia content in the gas coming out of such units is around 1%; such gas cannot be used for hydrogen recovery directly. If one wants to install a hydrogen recovery unit again, then unpowered ammonia recovery is not an option; only a pressure-based recovery tower can be used. The use of an isobaric recovery tower allows the ammonia content in the gas exiting the tower to be reduced to very low levels. Hunan Zhicheng Chemical uses an isobaric recovery tower manufactured by Tianjin Chuangju Technology Co., Ltd.; at an operating pressure of 1.9 MPa, the ammonia content in the gas after passing through this tower is 10 PPm, which is a very low level. This allows hydrogen to be extracted directly using a membrane separation unit.
Dear Mr. Guo: Your question is quite broad. Ammonia recovery takes place in several stages; for example, the integrated recovery tower in the carbonization system is part of the ammonia recovery process； The recovery of ammonia from the off-gases in the refining section falls under ammonia recovery ； Ammonia recovery from the vent gas of ammonia storage tanks can be achieved through methods such as isobaric water-washing ammonia recovery, equal-pressure central-tube ammonia recovery, and gravity-driven ammonia recovery ； The high-pressure water washing carried out before hydrogen extraction from the synthesized off-gas also falls under ammonia recovery. In short, the client wants to explain the ammonia recovery in that section. For specific issue discussions, you can send me an email and I’ll help you design a reference plan. My email address is liutaoandzdy@sina.com; I hope it will be helpful to the original poster and everyone else.
It is recommended to use a passive ammonia recovery device; the investment should be less than 100W, and the benefits are good
It mainly depends on the pressure in your synthesis system; if the pressure is high, gas can be blown out of the synthesis tower and then divided into two streams. One of these streams goes to the hydrogen recovery unit, which can meet the need to remove inert gases. The unpowered ammonia recovery unit is primarily used to recover the vent gas from spherical tanks, and the exhaust gas from hydrogen recovery can be used as a power source for ammonia recovery. It’s just my personal opinion; it mainly depends on the processing conditions
However, unpowered ammonia recovery is not easy to operate; when conditions change slightly, its operation becomes unstable. The composition changes greatly. This is also why unpowered ammonia recovery cannot be widely adopted under certain conditions.
