Liquid air separation plant solutions
Most liquid air separation plant cold energy receiving stations have a peaking role, their use is generally for domestic gas or car refuelling, with high and intermittent periods of gas consumption, for example 1-2 hour peaks in the morning and midnight. If the liquid air separation plant vapourisation plant is intermittent, the plant will not operate continuously. The solution is based on the intermittent use of liquid air separation plant and is characterised by a low number of moving devices and high performance requirements for cyclic start/stop moving devices. The solution uses liquid air separation plant cold energy conversion units, which can be converted into liquid air or liquid nitrogen, and air separation make-up cold units using liquid air or liquid nitrogen. The air is pressurised by an air compressor, then adsorbed with water and CO2 through an adsorber, and then passes through a booster and an air compressor to exchange heat with LNG in a high-pressure plate, then through a liquid expander to lower the pressure into the storage tank, and then the liquefied air is concentrated in a set of air separation units for distillation.
The liquid air separation plant designed by DearAir Separation avoids interruptions during operation and also allows a significant reduction in investment.
