Plants are increasingly being employed to clean up environmental pollutants such as heavy metals; however, a major limitation of phytoremediation is the inability of plants to mineralize most organic pollutants. A key component of organic pollutants is halogenated aliphatic compounds that include 1,2-dichloroethane (1,2-DCA). Although plants lack the enzymatic activity required to metabolize th...
This study provides a global warming impact analysis of environmentally friendly refrigerants used as replacements for R134a and R245fa. R290, R1234yf, R1234ze(E), R513A R450A are considered to replace in medium temperature applications. For R245fa, there five alternative refrigerants, R1224yd(Z), R600, R1336mzz(Z), R1233zd(E) R1234ze(Z), which selected high-temperature The is done considering ...
This paper investigates the feasibility of hydrocarbon refrigerant mixtures as a replacement for HCFC-22 in residential air-conditioning and heat pump systems. The COP and the seasonal performance factor (SPF) were calculated using a UA-model for single component refrigerants and refrigerant mixtures. Simulations were run for pure propane and the mixtures of propane/i-pentane, propane/n-butane,...
The experimental investigation of applying refrigerant Rl52a and zeotropes RI52al R22, Rl52al R221 Rl 14 to replacing refrigerant Rl2 is reported in this paper. The operating characteristics have been gotten using R 12, R I S2a, R ISia I R22 and R I 52a I R22 I R I 14 in the household refrigerator. The experimental results have been analysed. It is known that the·energy consumption of the refri...
