“…The primary booster system is mainly located on the surface, providing the cooling for the oil-free cycle in the cavern 100 m underground, consisting of evaporators. The secondary loop circulates the refrigerant through the evaporators inside the detectors [65]. The space in the cavern is limited, and radiation occurs, making R744 an appropriate refrigerant on both the low-and high-pressure sides.…”

During the last decade, many industrial and medical applications have shown a requirement for low-temperature-cooling usage (from −40 to −80 °C), which cannot be efficiently obtained via the conventional refrigeration systems usually employed for medium-temperature applications (from 0 to −40 °C). A proper ultra-low-temperature (ULT) refrigeration system design is essential to achieve the desired output. The performance can be maximised via the suitable selection of the configuration and refrigerant for a specific temperature range. This work contributes a detailed overview of the different systems and refrigerants used in ultra-low-temperature applications. Different systems, such as single-stage vapour compression, multi-stage, cascade, auto-cascade, and air refrigeration cycles, are presented and discussed. An energy analysis is then carried out for these systems identifying the optimal system design and refrigerant selection to achieve the highest performance. This paper aims to provide the reader with a comprehensive background through an exhaustive review of refrigeration systems suitable for ultra-low-temperature applications. The effectiveness of these systems is proven numerically, mainly based on the temperature level and purpose of the application.

Considering that two-thirds of world oil production receive a treatment after extraction to remove water and salt contents, one of the most important processes to avoid operational problems in refinery plants corresponds to the dehydration and desalting unit. Here, live crude oil at high temperatures and pressures is processed and stabilized. Henceforth, to optimize these petrochemical plants, simulation has become an important tool. Nevertheless, due to its sequential modular nature related with mass/energy recycle steam circuits, the modelling and simulation of this process is commonly simplified. Thus, to reproduce the process behaviour of the unit under operating conditions and identify its effect on the final product, this work presents an unpublished rigorous dynamic simulation-based procedure of a complete real dehydration and desalting process using Aspen HYSYS ® . Different pieces of equipment are carefully designed based on literature review, and a specially tailored procedure is proposed to estimate the water and salt contents at any stage of the plant. Finally, to validate the simulation, the accuracy of the main flows and chemical contents along the process are compared with actual data.
