Liquid air separation factory

For the pipeline with pressure, the easiest problem in the production process is the leakage at the connection flange. Once leakage is found, do not tighten the bolt under pressure. There are some reasons for the leakage in the process of operation, such as gasket damage, pipeline under thermal stress, etc. At this time, the problem can't be solved only by twisting the bolt, and often screw the Bolt hard because the leakage has not been eliminated until the bolt is broken and the high pressure gas in the pipe sprays out, causing injury accidents. There have been several factories which have suffered from the accident of Bolt fracture caused by the screw bolt with pressure and the casualty of flange plate flying out. Therefore, it is necessary to strictly abide by the regulation that the screw bolts with pressure are not allowed, and it is not allowed to hold fluke mentality and violate the operation regulations in order to seize time and catch up with tasks.

The three-point temperature of the low temperature of the air separation tower is: T3 temperature refers to the temperature before the high pressure air throttles; T2 temperature refers to the temperature of the air after expansion; t1 refers to the temperature after the first heat exchanger and before the expansion machine. The function of the three-point temperature is mainly to control the gas distribution between the expansion machine and the joint-1 valve during the start-up stage of the air separation tower. There is no need to control the normal and stable operation. If only one or two of the thermometer is out of order, we can speculate the working condition according to the intact temperature point. When the three-point temperature is completely out of order, it can be operated according to the temperature difference between the Heat end of the heat exchanger (namely the temperature difference between the air inlet device of processing air and the outlet temperature of oxyg...
