24 Claims

1. A method for the controlled production and distribution of butane enriched diluents so as not to violate pre-defined limits selected from butane content, volatility, density, and combinations thereof comprising:

a) providing a diluent stream having a flow rate, a line pressure, a butane content, a volatility and a density;

b) providing a variable rate butane injection unit in fluid connection with said diluent stream;

c) obtaining values for one or more parameters of said diluent stream selected from butane content, volatility, density, and combinations thereof;

d) adjusting a rate of injecting butane into said diluent stream based upon the one or more parameter values in step (c) so as not to violate the foregoing pre-defined limits; and

e) injecting butane into the diluent stream from the butane injection unit at a pressure greater than said diluent stream pressure, and the adjusted rate from step (d).
