In this calculation weâll use an ethane heat content of 66,500 BTU per gallon. The top boxes in Figure #1 show the conversion of the ethane price per gallon to dollars per MMbtu. So if the price of ethane is 22 cents, divide by 66,500 and multiply by 1,000,000 to yield an equivalent gas price of $3.31/MMbtu.
3 are compared, the dew temperature of methane+ethane+butane mixture is 273.15 K at 60Ã10 5 Pa (Fig. 2) . If 100.79Ã10 â6 kg m â3 (STP) (y =0.00012) of water is added, the dew temperature of the mixture is displaced by approximately 2 K (Fig.3) .rior to the study of methane+ethane+butane and methane+ethane+butane+water mixtures, the performance of both the analytical method and the experimental procedures used for the present work was determined [2] .
