Mixed refrigerant(MR)component is one of the most important factors that influence the performance of natural gas liquefaction process.In certain kinds of liquefied natural gas(LNG)plants
heavy hydrocarbons in MR
such as butane and pentane
are not welcome.In this paper
four kinds of MR components have been used in the single mixed refrigerant(SMR)process:MR with both i-butane(C4)and i-pentane(C5); MR without C4; MR without C5; MR without C4 and C5.The specific power consumption has been compared.The results show that compared with i-butane
i-pentane has greater contribution to the decline of power consumption and that the power required in condition 1 is 18% less than that in condition 4.Furthermore
the SMR liquefaction processes with different pre-cooling refrigerants have been proposed.Compared with condition 4
there is a 12% decline in power consumption for the process with propane pre-cooling.
