“…However, special care should be taken when the operating temperature is above 165°C. Additionally, in a more recent work [75] showed the effectiveness of Po-Mo (an organophosphonate plus Sodium Molybdate) as a corrosion inhibitor in 55 % Lithium Bromide at 240°C, with maximum corrosion rates as low as 25 µm/year. Figure 7 illustrates the data measured by the Japan Gas Association at three different locations of the generator model test sections (see figure 7(b)): (1) transfer tube, (2) separator clearance, and (3) separator welding.…”

The use of waste heat or low-exergy heat sources represents a strategic opportunity to reduce the environmental footprint and operation cost of industrial processes. The absorption heat transformer, also known as absorption heat pump type II, is a thermal machine which can boost the temperature of a heat flow by using a negligible amount of electrical power.However, owing to the lack of established technical knowledge and the absence of comprehensive recordings of successful heat transformer applications, the feasibility and reliability of absorption heat transformers have been questioned and the diffusion of this technology remained limited.Therefore, in this paper, all the industrial applications of the absorption heat transformer that are recorded in previous literature and yet unpublished reports are presented and discussed.In addition to literature research, intense knowledge exchange with three leading manufacturers of absorption heat transformers gave an accurate perspective on the technological level of commercial products and operative installations. It is shown that between 1981 and 2019, 48 absorption heat transformers have been installed in 42 plants with a total capacity of ≈ 134 MW. Two main implementation periods, separated by 25 years of infrequent heat transformer installations, have been recognised. More than 74 % of the installations were in Asia. Approximately 61 % of the heat transformer installations were applied into the chemical industry.Therefore, through the analysis of the technical challenges and their solutions, along with related economical aspects of heat transformer installations, the effective state-of-the-art of 1

“…Fe is often used as the material for the pipes conducting the flow and heat exchange of the LiBr solution. However, Fe usage has three drawbacks: the corrosion by aqueous Br – of Fe, pipe blockage by LiBr crystal deposition at low temperatures, and high flow resistance to highly concentrated, high-viscosity LiBr solutions . Some preventative measures such as anticorrosion additives or crystallization inhibitors have been adopted, but these methods may increase operating costs and environmental risk.…”

“…However, Fe usage has three drawbacks: the corrosion by aqueous Br − of Fe, 22 pipe blockage by LiBr crystal deposition at low temperatures, 23 and high flow resistance to highly concentrated, high-viscosity LiBr solutions. 24 Some preventative measures such as anticorrosion additives 22 or crystallization inhibitors 25 have been adopted, but these methods may increase operating costs and environmental risk. Since superhydrophobic surfaces can effectively realize anticorrosivity, drag reduction, and scaling resistance simultaneously, the application of such a functionalized surface to Fe could solve these three problems simultaneously.…”

LiBr refrigerating systems are frequently used in industry, but the pipelines are easily corroded or blocked by the LiBr solution with high flow resistance. Here, a superhydrophobic Fe surface was proposed and tested for applicability. After constructing a rough Fe 2 O 3 nanotube array on a Fe surface by the anodization process, a superhydrophobic Fe surface was obtained by silane modification. The as-prepared superhydrophobic surface exhibited excellent repulsion to LiBr solutions. The modified Fe foil showed a 3.35% decrease in thermal conductivity but a 99.2% improvement of anticorrosion protection efficiency. LiBr crystals deposited on this surface were easily detached. The flow resistance along the superhydrophobic surface was reduced to 50% of that along a pure Fe surface. The operation temperature of the system was broadened due to low blockage risk. The excellent thermal conductivity, anticorrosivity, drag reduction, and antifouling performance of the superhydrophobic Fe surface exhibits promise for industrial application.

The effect of benzotriazole (BTAH) on the corrosion fatigue behavior of α‐Al bronze in 1 M LiBr solution has been investigated using reverse bending technique during testing it in LiBr/H2O system. The adsorption equilibrium estimated to be 1431.25 M−1 while the free energy of adsorption to be −27.968 kJ mol−1. The BTAH feature found to improve the fatigue life to a value near to that of α‐Al bronze in air. The optical and scanning electron microscopy for the α‐Al bronze for the fatigued in air, revealed that the fracture mode was transgranular and that the initiation and propagation was transcrystalline. α‐Al bronze fatigued in 1 M LiBr showed less fatigue resistance when compared to that of α‐Al bronze fatigued in air. The addition of 0.02 M of BTAH to 1 M LiBr increased the fatigue life and fatigue strength for α‐Al bronze where its fatigue behavior curve was close to that of air. The results demonstrated obviously a reduction of the corrosion fatigue resistance of α‐Al bronze in 1 M LiBr solution but it has a considerable increase in the presence of BTAH.
