Optimization and analysis of mixed refrigerant composition for the PRICO natural gas liquefaction process

Knowledge inspired investigation of selected parameters on energy consumption in nitrogen single and dual expander processes of natural gas liquefaction

“…Fig. 7 shows that there is an optimal pressure difference for the nitrogen refrigerant that minimizes the compression energy when MITA is maintained at 3 C (Hasan et al, 2009;Xu et al, 2014). As the low pressure of nitrogen refrigerant in the cycle is increased, the overall pressure difference on which the compressors are operating is decreased.…”

Experimental and theoretical investigation on the performance of CO2/propane auto-cascade refrigerator with a fractionation heat exchanger

“…As the heart of refrigerator, the compressor is reciprocating hermetically-sealed type with a displacement of 17.69 cm 3 …”

“…Usage of natural refrigerants, such as carbon dioxide (CO 2 , R744), hydrocarbons (propane, butane, etc.) and their mixtures, is increasing [2][3][4][5][6][7][8][9][10]. Both CO 2 and propane (C 3 H 8 , R290)…”

Impact of urban and industrial effluents on the coastal marine environment in Oran, Algeria

“…Approximately 900 ha are reserved for the petrochemical manufacturers, 400 ha are kept for pipeline in the technical corridor, as well as cables between different units and oil/gas gates. The pole consists of a large number of hydrocarbon and petrochemical plants, Liquefaction Natural Gas/LNG (GL1Z, GL2Z, GL3Z, and GL4Z: non-operating since 2010) (Wooler, 1975;Woolcott, 1987;Sun et al, 2012;Xu et al, 2014), Liquefied Petroleum Gas/LPG (GP1Z and GP2Z) a Refinery RA1Z (Mercier, 1966), three units of Ammonia and Nitrogen Fertilizers production (Fertial, Al Djazaïria Al Omania LilAsmida (AOA), and Sorfert) (BAT, 2000), Methanol synthesis CP1Z, Electricity generation plant, and Seawater desalination system. On the other hand, the western region is touristic destination, famous for its beaches, hotels, landscapes, mountains and small villages.…”
