Floating valve design for small air separation units
The valve is designed to move in the only opposite direction during operation, specifically during start-up so that the valve contracts downwards with the pipeline and just above the centre of the valve barrel. The floating valve design makes the valve and piping system a moving whole, effectively reducing the stress on the entire piping system and improving the safety of the liquid air separation plants.

  After refrigeration, of course, liquid air can be used as the cooling source to provide the condenser with cold quantity to organize the deep cooling air separation process. However, it is difficult to choose heating to reboiler. Most of the commonly known substances are solid state and cannot be used as heat carrier under the condition of deep cooling. Of course, electric heating is not available,...

Water circulation, whether it's new or old, requires system cleaning and pre-filming before dosing. The pretreatment of circulating water systems for chemical treatment includes cleaning work and pre-film work. For new systems, small air separation units and piping can sometimes have debris, debris and dust left in the system during installation, and sometimes cooling equipment can be heavily rusted and oiled. If these debris and oil are not cleaned, they will affect the next step of the pre-fil...
