The original issue with driving
Thread Content
Gentle experts, the chlorine main pipe in my chlor-alkali plant is made of new titanium tubing and is not insulated. Is there any problem with driving like this? Will it be able to start successfully? The current outdoor temperature is about 5 degrees Celsius
If the slope is well controlled, there shouldn’t be any major problems
Is the poster worried about condensation water freezing? A temperature of 5 degrees Celsius is no problem; insulation isn’t necessary. During normal production, the temperature of the liquid coming out of the electrolyzer is relatively high, so it needs to be cooled and dehydrated, which is why the pipes don’t require insulation.
No matter how low the outdoor temperature is, the temperature of the chlorine gas exiting the tank remains above 80 degrees, reducing the burden of chlorine gas washing
It seems that the chlorine pipeline does not require insulation.
It is essential to ensure that the condensate can be drained from the main pipe in a timely manner; if this is done, there will be no problems during operation
Driving the equipment should be no problem, but attention needs to be paid to the chlorine water pipelines. It’s best to provide insulation and heating for them. When my factory first started operating the equipment, I was a novice and didn’t know these things; in winter, due to the harsh weather in the north, all the chlorine water pipelines would freeze up completely~~~
It would be best to have insulation, as large temperature fluctuations (day-night differences) can affect the chlorine pressure

Lack of insulation can cause large fluctuations in chlorine pressure during sudden weather changes or when it rains, leading to frequent shutdowns. Furthermore, when the temperature is low, the condensate water may crystallize; the crystallization temperature of chlorine water is 9.6 degrees Celsius.
What was said on the 9th floor is very good; pay attention to the key points: 1) The chlorine water in the pipes must be able to flow out properly, either through a slope leading to the washing tower or through chlorine water pipes leading to the chlorine water tank. If it is discharged through chlorine water pipes, heat tracing needs to be installed on those pipes； 2) If the main chlorine pipeline is located in a rainy area, it is advisable to add insulation; it does not need to be very thick, as the main concern is to prevent sudden changes in pressure differences between hydrogen chloride due to temperature fluctuations caused by rain, which could lead to interlocks being activated.
Titanium tubes lacking insulation have both advantages and disadvantages. The advantage is that they help to reduce the water content in chlorine, thereby lowering the cooling energy required in the chlorine treatment process; they also contribute to reducing the amount of acid used； The drawback is that in cases of sudden weather changes, the chlorine pressure can experience significant fluctuations, especially during the rainy season in summer ； From the company’s perspective, as long as the operators have the necessary skills, I prefer not to use insulation
