Issues related to the sharing of long-distance pipelines
Thread Content
The company has 8 storage tanks: 2 designed for phthalene, and one each for toluene, xylene, methanol, butanol, octanol, and ethylene glycol. However, there are only 4 pipelines leading to the dock. Experienced colleagues, which materials can share pipelines, and which require dedicated pipelines? Thank you!
I haven’t worked with this before, but I think that when it comes to products leaving the factory, ensuring their quality is of utmost importance. It’s best to use nitrogen to remove any oil from the pipelines after use, in order to prevent quality issues that could arise from mixing oils of different types. If the quality requirements aren’t very high, then oils with similar specifications can be used together; in that case, it’s advisable to consult with the quality control department
I have no experience, but let’s discuss it together. First, consider the material quality requirements, the amount of medium allowed to be mixed in, and the difficulty of pipeline purging. Secondly, it needs to be classified based on the operating parameters of the material and the requirements for the pipeline material; for example, benzene may require insulation and heating ； Ethylene glycol requires stainless steel pipes. Finally, the transfer volume also needs to be taken into comprehensive consideration. Massive enjoyment under specialized management.
What materials should be used for ethylene glycol storage tanks and pipelines? Is ethylene glycol corrosive?
1 For large volumes, use separate pipelines; 2 for applications with high requirements regarding impurity levels, use dedicated pipelines; 3 the reactions may not be compatible with each other. Can someone in charge provide some information?
This relates to sequential transportation, and two issues need to be considered: 1. the concentration at which a certain material specified in the standards is allowed to mix with another material； 2. Calculations or experiments are used to determine the amount of mixture formed during the sequential transportation of these two materials at a certain flow rate. Some materials require extremely high purity levels, such as **. The most important aspects in the sequential transportation process are the calculation of the amount of mixed oil, as well as the issues related to the separation and treatment of such mixed oil.
