I’m here to ask for advice again. I might have quite a few questions. Thank you in advance

1. In the process of transporting the generated gas to users, is it the pressure difference that drives this process? —— Yes.
2. Acetylene has a high temperature; why does it contain moisture? Is it affected directly in the calcium carbide reaction? ------It is that the raw material calcium carbide contains sulfur and phosphorus. Calcium sulfide and calcium phosphide react with water to produce hydrogen sulfide and phosphine. 3. At what liquid level in the sump does overflow begin? During this period, the liquid level in our sump has been abnormal and kept dropping, from 6 meters initially to 5 meters now. Overflow occurs when the value obtained by converting the reaction pressure into a height, adding the height of the reaction liquid level, and subtracting the height of the overflow pipe is positive. (The heights of the benchmarks must be consistent.)

Thank you very much. I’ve added you as a friend; it’s great to have met you. Acetylene has a high temperature and contains sulfur and phosphorus. Is it that during the calcium carbide reaction, when the temperature is too high, the acetylene temperature rises, the reaction becomes more intense, and thus more sulfur and phosphorus are produced? Actually, I really want to know: since acetylene gas has a high temperature, why does it contain sulfur and phosphorus?

First, let me make one thing clear: it’s not that a higher temperature leads to higher levels of sulfur and phosphorus, nor is it that lower temperatures result in no sulfur or phosphorus being present. As long as the raw material, calcium carbide, contains impurities such as calcium sulfide and calcium phosphide, hydrogen sulfide and phosphine gases will be generated. This has nothing to do with the temperature level; temperature only affects the reaction rate, but has no bearing on whether these substances are produced or not.

At higher reaction temperatures, the reaction becomes more vigorous; the solubility of gases in the slurry decreases, thereby reducing the loss of acetylene. However, the same applies to impurity gases relative to the main product, acetylene.

Excuse me, when the pressure difference and flow rate are around 8,000, the pressure differential is only about 4,000–5,000 Pa. For example, the pressure in the main pipe is 57 kPa, while that at the user end is 54 kPa. My question is: can such a small pressure difference actually be effective? Thank you

I’m a bit confused about the overflow theory. Could you please explain it in detail? Examples would be greatly appreciated. Thank you so much?

1. The cooling effect is poor; the temperature of acetylene is high. 2. The temperature of the circulating water inside the pump head is also high. I really can’t figure out how these two factors might affect Nasim’s outlet pressure. Please help analyze this, thank you

With a flow rate of around 8,000, the outlet pipe should be DN500. A small pressure difference indicates that your pipeline is unobstructed; otherwise, a large difference would be problematic.

High acetylene gas temperature and high circulating water temperature can both affect the load on the water-ring compressor. Firstly, the water-ring compressor uses water as a medium to compress acetylene gas. During this compression process, due to the contraction in volume of the acetylene gas, heat is inevitably released. If the temperature of the operating water is too high at this time, the compression ratio of the acetylene gas will decrease. Consequently, the outlet pressure of the compressor will be affected under the same load conditions. In severe cases, it becomes evident that the water-ring compressor fails to draw in sufficient amounts of gas; the liquid level in the acetylene gas holder rises, and the flow rate of acetylene gas supplied to customers becomes inadequate.
