Common thermometer of air separation plant

There are four kinds of commonly used thermometers in air separation plant: industrial internal standard glass thermometer, thermocouple thermometer, thermal resistance thermometer and pressure gauge thermometer. According to the principle of temperature measurement, the range of temperature measurement and whether it can be transmitted remotely, four kinds of thermometers are used in different temperature measuring occasions of air separation plant. Industrial internal standard glass thermometer is used in small air separation plant to measure the temperature of all levels of compressor gas and cooling water locally, and it is also used for temperature measurement during heating and thawing; thermocouple thermometer is used for purifier; thermal resistance thermometer is used for low temperature measurement inside cold insulation box; pressure gauge thermometer is used for measuring lubricating oil temperature.

Influence of atmospheric environmental conditions on performance of air separation plant

The environmental conditions considered by the air separation plant include: altitude, atmospheric pressure, ambient temperature, air humidity, the content of impurities such as carbon monoxide in the air, etc. These conditions vary with different regions and environments. Different environmental conditions have different effects on the performance of the same air separation plant. 1. Influence of atmospheric pressure on air separation plant: Atmospheric pressure is the pressure exerted on objects in the atmosphere by the gravity of the atmosphere itself. In general, the atmospheric pressure is about 0.1MPa. When the atmospheric pressure decreases, the compression ratio of the air compressor will increase, which will increase the energy consumption of the air separation plant. 2. Influence of ambient temperature and humidity on air separation plant: The increase of ambient temperature will reduce the air compressor's exhaust volume, increase the exhaust temperature, increas
