Improved process for blending refrigerants

摘要

A method for forming a multi-component refrigerant composition comprises;
(a) introducing a first refrigerant component into a vessel at a first flow rate;
(b) introducing at least a second refrigerant component into said vessel at a second flow rate, which may be the same as or different than the first flow rate, during at least a portion of said first refrigerant introducing step; and
(c) controlling at least one of said first and second flow rates to obtain the desired relative proportions of said first and second refrigerants in the refrigerant composition.
