What faults are likely to occur with the Hampson liquid level meter

Problems with the liquid level gauge can occur in three ways: high, low or unstable indications.First of all, check whether the liquid level meter is leaking, pass an air source into the positive pressure chamber and block the negative pressure chamber to see if there is any air leakage. The high indication is generally due to a leak in the negative pressure chamber, which increases the differential pressure; the low indication is due to a leak in the positive pressure chamber, which decreases t...

Form design of optional components for liquid air separation plants

1. Design of membrane frameThe main skeleton design uses I-beam steel, focusing on neat and solid appearance, including local strengthening design.The design of the main skeleton is made of I-beam steel, mainly focusing on a neat and strong shape, including local strengthening design. The design is mainly based on the selection of some components that are used frequently and are more critical in the liquid air separation plant, including regulators, manual valves, duplexes, needle valves and oth...

How to start the booster turbine expander for liquid air separation plant?

Steps to start the booster turbine expander for liquid air separation plants. Prepare the booster turbine expander for start-up in accordance with the requirements. The compressed air enters the lower tower in liquid air separation plant. High pressure air pressurised by the booster end of the booster turbine expander in liquid air separation plant, then cooled and throttled by the main heat exchanger into the lower tower; maintaining a lower tower pressure of around 0.35 MPa. The pressuri...

What is liquid air separation plant adsorbent？

Liquid air separation plant molecular sieve adsorbers are used to remove impurities such as moisture, carbon dioxide and acetylene from the air by adsorption. The porous solids used in the adsorption process are called adsorbents. The requirements of the adsorbent are mainly the following. 1) The adsorbent must be a porous substance. Adsorption can only be carried out on the surface of the solid, the more voids, the larger the surface area, the stronger the adsorption capacity. 2) The adsorbe...

Effective energy analysis of cold energy utilisation in liquid air separation plants

Effective energy analysis is an important analytical method for energy systems. Liquid air separation plant is a low-temperature liquid mixture with methane as the main component, including nitrogen, ethane, propane and other components, which has a large temperature difference and pressure with the outside world. Liquid air separation plants's temperature accompanied by phase change heat, so its cold energy is divided into sensible heat and latent heat. The effective energy analysis shows that ...

Liquid nitrogen separation system in liquid air separation plants

After pressurisation, it returns to the heat exchanger to recover the cold volume of liquid air separation plants and liquefy it into liquid nitrogen, part of which is warmed up to about 123°C by the heat exchanger through the eighth pipeline after a history of throttling, and is pumped out to the medium pressure circulation nitrogen press. Another part of the liquid nitrogen enters the first gas-liquid separator via the fifth pipe. Part of the separated liquid nitrogen goes through the seco...
