Urea maintenance costs
Thread Content
Let’s discuss the maintenance cost of urea, I’ll go first. We use reciprocating compressors, and the equipment and pumps are made in China, so the maintenance cost is quite high, about 2.5-3 yuan/t.
Which section of the work does the 2.5-3 yuan/t mentioned by the poster refer to? What equipment is included? The production scale, single machine capacity, etc. seem to be affected. Can you tell me the average maintenance cost of the entire plant per ton of ammonia?
Due to the material requirements for pipes, fittings, valves and other materials used in urea, the price is expensive. If the output of urea is small, the cost estimate mentioned by the poster may not be enough. This maintenance cost can only be determined based on the actual situation of the factory.
What I am talking about is the urea workshop, which is the maintenance cost from the CO2 compression section to the finished product. The maintenance cost is the maintenance of the compressor, including the maintenance of spare parts, pumps, valves, etc. The production scale will have a certain impact, but it is equivalent to tons of urea. If I want to know the maintenance cost of the whole plant, if I convert it to urea, it is about 8-10 yuan/ton.
I think this fee should not include equipment updates and minor improvements, right? I generally feel that your factory's maintenance fees may be lower than ours. What is the capacity of your factory's single compressor? Is it 305 parties?
Our reciprocating compressors, a single unit of 115 cubic meters, four units in total
Then Koala Friend’s compressor operation method is three on and one on standby, right? If so, your compressor maintenance costs will probably not be very low.
Our company's urea production uses the aqueous solution full cycle method. The maintenance fee for urea is assessed at 6.5 yuan/t, but the cost of major and minor repairs is not included. If the quality of the imported materials is guaranteed, it is basically enough. Engine oil is separately assessed based on 0.1kg/t urea.
