The results of minor improvements and reforms should also be included
Thread Content
Everyone is welcome to come and share the small improvements and innovations they have made in their production processes, as well as the results of their QC efforts. Specific measures were taken to address the problems existing in production. Let’s bring them all out and talk about them. Brainstorm. Let me start with one point: The refrigerant oil accumulated in the two ammonia coolers of the synthesis system is discharged into an oil collection tank through a drain line; after being boiled in a steam coil, it is filtered and reused. You can save around 20,000 yuan on fuel costs over the course of a year.
By utilizing the urea vapor condensate, newly installed lithium bromide chillers produce 7-degree cold water for cooling the gas before the compressors, resulting in a significant increase in production.
Our plant’s ammonia cooler has been in operation for over 3 years without any oil being drained at all!! It seems like there isn’t any problem either. Is there really that much oil?
Check his syngas compressor and the oil leakage from the chiller!
The oil separator of an ice machine cannot completely remove the oil. Ammonia coolers will definitely accumulate oil, as liquid ammonia in these coolers evaporates more easily than oil. But you don’t have to schedule it either. It’s just that the temperature difference for ammonia cooling is a bit greater. The chiller has a higher load, that’s all. It also increases consumption. Perhaps you at Dahuah don’t notice small changes, but we at Xiao Fehua can only reduce consumption by working more meticulously. Personal opinion. :handshake :handshake :handshake
Agreed; we schedule 3 sessions per week, which is about half a tank’s worth. The issue with ammonia cooling is also quite apparent. We’ve been using it for 3 years now, and we still installed an oil separator at the outlet of the circulation pump – more oil is needed there as well.

Due to the dual-high-pressure renovation of the system, the condensate tank needs to be relocated. After the relocation, the layout of the pump inlet pipeline differs significantly from the original one. When the liquid level in the condensate tank is low, the mechanical seal of the condensate pump often gets damaged; it is necessary to replace it at least three times a week, resulting in extremely high maintenance costs. By adding a feed line for seal water with dimensions of Φ14×2.5 at the mechanical seal of the condensate pump, allowing this water to flow directly into the pump body, the operating cycle of the condensate pump was increased to 60 days. This minor modification yielded very significant results. Share it.
Frequency conversion technology is used to adjust the outlet flow rate of the centrifugal pump, resulting in a reduction in current of about 20% compared to before
A dimethyl liquid preheater was added, and the steam pressure of the first-stage evaporation heater was reduced from 0.8–0.9 MPa before the modification to 0.6–0.7 MPa
By adding a condenser and a separator in front of the first absorption tower for urea, the load on that tower is significantly reduced, making it easier to operate.
Our low-pressure hermetic water coolers have been changed from series to parallel configuration, improving the cooling effect.
Evaporative condensers can save water, while pressure swing adsorption for carbon removal helps save electricity
Due to increased system load, the heat exchange area of the high-pressure water heat exchanger is insufficient. Originally, it was necessary to install another heat exchanger to increase this area; now, instead, a high-flow pump will be added, with one pump in use and the other as a backup. When the load decreases, the high-flow pump is used, which not only solves the heat exchange problem but also provides an additional backup pump. Kill two birds with one stone.
