“…Ma et al [ 46 ] reported the same behaviour, where the temperature did not affect the removal of MB dye by the studied biosorbent. By contrast, Lateef Tarish et al [ 84 ] observed that MB removal was optimized at 303 K, whereas Chandarana et al [ 49 ] obtained better MB removal at higher temperatures of 303–323 K.…”

Methylene blue and safranin orange dyes, which are used in the textile and pharmaceutical industries, can severely damage the environment and human health. This study investigated the use of okara residue as an alternative biosorbent for the removal of methylene blue and safranin orange dyes. Substantial amounts of okara residue are generated daily during the processing of soy milk in the agro‐industrial sector. Dye adsorption was not affected by pH. An adsorption study identified the optimal experimental conditions as: 298 K, 0.03 g of adsorbent in 30 mL of dye solution at a concentration of 50 mg L−1, and a contact time of 300 min for methylene blue dye, and 298 K, 0.02 g of adsorbent in 30 mL of dye solution at a concentration of 50 mg L−1, and a contact time of 200 min for safranin orange dye; the maximum adsorption capacities were 93.201 ± 0.01 and 184 592 ± 0.02 mg g−1, respectively. Okara has considerable advantages over other natural materials as an alternative for the treatment of industrial effluents. Because it is easily obtained and does not require any physicochemical treatment, adsorption does not require any specific operation temperature. In addition, okara exhibited a high adsorption capacity compared to other natural materials that require chemical and physical processing for adsorbent preparation.

“…HMOOD et al 8 reported that R1234yf could be a better drop in alternative to high GWP refrigerant R134a. Tarish et al 9 perform the exergy analysis using R161 operated in split air conditioner to find an alternative to R134a and R22 in different Iraq climate and find that the exergy efficiency of R161 operated system is 8.6% and COP is 7.3% higher than the R134a and R22 operated systems. Kaushik and Arora 10 establish a computational model for calculating exergy destruction in VCR system and discover that The condenser is the part of the system where the most of exergy is lost, trailed by the compressor.…”

In this research, a split air conditioner's performance has been evaluated using exergy analysis on three different low global warming potential (GWP) refrigerants, namely R32, R447A, and R447B, to find a replacement for the GWP-high refrigerant R410A. With regard for pressure loss in the evaporator and condenser, a computational model is built to recreate the operational conditions of a split air conditioner. GENETRON Properties 1.4 software is used to calculate performance metrics such as coefficient of performance (COP), exergy destruction ratio, exergetic efficiency, and efficiency defect. Result shows that pressure drop in evaporator alone has an adverse effect on COP and total exergy destruction and it is higher at higher pressure drop. Effect of pressure drop on exergetic efficiency and exergy destruction ratio is found to be less significant with condenser pressure drop compared to evaporator pressure drop. Exergy efficiency is found to be maximum with R447A followed by R447B, R32, and R410A.
