1. A plant comprising:
- a fractionator configured to receive a C5+ hydrocarbon mixture feed and to produce from the C5+ hydrocarbon mixture an overhead distillate, a mid-stream product, and a bottom product;
a first mixing device that is fluidly coupled to the fractionator and configured to mix the overhead distillate and the bottom product to form a first C5+ product having a controlled RVP;
a second mixing device that is fluidly coupled to the fractionator and a C5+ source, wherein the C5+ source is configured to provide a C5+ stream; and
wherein the second mixing device is configured to mix the mid-stream product and the C5+ stream to form a second C5+ product having a controlled RVP.

Abstract
Controlled RVP C5+ products are produced from feed gas in configurations and methods in which a heavier portion of the feed gas is fractionated into several streams having distinct RVP and in which a C5+ stream is produced from the lighter portion of the feed gas. The so formed streams are then combined to produce C5+ products with controlled RVP. Thus, RVP control is achieved without the need for external products for blending process streams derived from the feed gas.

9. A method of forming C5+ products having controlled RVP, comprising:
-
separating a feed gas in a separation unit to thereby form a gaseous fraction and a liquid fraction; processing the gaseous fraction to form a C5+ stream, and processing the liquid fraction in a fractionator to form an overhead distillate, a mid-stream product, and a bottom product; combining the overhead distillate and the bottom product to form a first C5+ product having controlled RVP; and combining the mid-stream product and the C5+ stream to form a second C5+ product having controlled RVP. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
