air separation energy storage patent

How can a cryogenic air separation unit save energy?

Liu et al. proposed an external compression ASU with energy storage, saving 5.13 % of the power cost. Wang et al. introduced a cryogenic distillation method air separation unit with liquid air energy storage, storing waste nitrogen to store cold energy with a payback period of only 3.25–6.72 years.

Does air separation industry have a high power consumption?

The air separation industry is a crucial foundation for various industries, but its high power consumption leads to substantial operating costs. To address these issues, this paper proposes a system of LAES-ASU and establishes a mathematical model. This model is analyzed in terms of energy, exergy, and economy. The conclusions are as follows:

Is air liquefaction similar to air separation unit (ASU)?

The air liquefaction process of LAES bears similarity to that of an Air Separation Unit (ASU). Coupling LAES with ASU has several benefits. He et al. proposed an air separation unit with energy storage and power generation, achieving a round-trip efficiency of 53.18 %.

What are the advantages of liquid air energy storage (LAEs-ASU)?

The operating costs of air separation unit are reduced by 50.87 % to 56.17 %. The scale of cold storage unit is decreased by 62.05 %. The LAES-ASU recovers expanded air, thereby eliminating energy wastage. Liquid air energy storage (LAES) emerges as a promising solution for large-scale energy storage.

What are the different types of energy storage technologies?

Currently, the technologies widely applicable for large-scale energy storage include battery energy storage (BES) [9, 10], pumped hydro storage (PHS) [11, 12], compressed air energy storage (CAES) [, , ], and liquid air energy storage (LAES) [1, 16].

Is liquid air energy storage a viable solution for large-scale energy storage?

Liquid air energy storage (LAES) emerges as a promising solution for large-scale energy storage. However, challenges such as extended payback periods, direct discharge of pure air into the environment without utilization, and limitations in the current cold storage methods hinder its widespread adoption.
