What are the reasons why the main cooling liquid level of the air separation equipment is not high and how to solve it?
There are several reasons why the main cooling liquid level is not high:
1. The incomplete heat exchange loss of the main heat exchanger increases;
2. The expansion machine has a small temperature difference, low efficiency, and less expansion;
3. The temperature of the air entering the main heat exchanger is high;
4. Equipment leakage increases the loss of cold running;
5. A large amount of liquid products are taken out.
The solution is as follows:
1. Reasonably allocate cooling capacity, and if the heat exchanger is blocked, it should be fully heated and blown out;
2. Check the expander and handle it;
3. Check the air cooling system and molecular sieve adsorber and handle them;
4. Inspect cold insulation materials, detect leaks, and handle them;
5. Reduce the amount of liquid extracted.

Liquid air separation plant liquid hub area piping arrangement is mainly oxygen, nitrogen, argon liquid pipeline and pump box in the liquid pipeline arrangement. As oxygen, nitrogen, argon liquid temperature is extremely low (liquid oxygen -183 ° C ℃, liquid nitrogen -196 ° C, argon liquid -185.7C), in the liquid flow process, resulting in a certain amount of gasification, piping should pay attention to the slope of the liquid pipeline towards (no slope requirements on the process). In ...

Air cooling column is a mixed heat exchange device. The function is to make the cooling water fully contact with the air and being mixed fully to increase the heat transfer area and enhance the heat transfer, usually using "packed column" or "sieve plate". The packed column is a round steel container with packing (ceramic ring, plastic ring, etc.). Cooling water is ejected from the top of the column and mixed with air flowing upward from the bottom for heat and mass exchange. Air transfers heat to the cooling water, lowering its temperature and raising its temperature. In order to prevent the generation of water droplets in the air, the raschig ring (or stainless steel wire mesh) packing separator (also known as trapping layer) and mechanical water separator (inertial separation) are usually installed on the upper part of the column. The cooling water ejected from the spray device flows downward to the packing layer through the distributor, and an overflow ring is provided to redist
