Process and system for blending synthetic and natural crude oils and blends made thereby

摘要

A process and system are described for producing a synthetic crude oil by contacting a synthesis gas with a combination of a synthesis gas conversion catalyst and a hydroconversion catalyst in a synthesis gas reactor. The synthesis gas can be obtained from gas associated with crude oil production, i.e., associated gas, in a synthesis gas generator. The synthetic crude oil can be blended with a natural crude oil to produce a blended stabilized crude oil having 2 wt % or more of the synthetic crude oil. The resulting blended stabilized crude oil has improved flow characteristics including a pour point of 30° C. or less.

1. A process for producing a blended stabilized crude oil from a stream of produced fluids produced from a hydrocarbon containing subterranean reservoir, the process comprising:
(a) converting synthesis gas in a conversion reactor, in the presence of a synthesis gas conversion catalyst and a hydroconversion catalyst, into a tail gas and a liquid effluent stream including liquefied petroleum gas and synthetic crude oil; and (b) sending at least a portion of the liquid effluent stream to a separator and separating the liquefied petroleum gas from the synthetic crude oil; and (c) producing a blended stabilized crude oil containing natural crude oil obtained from produced fluids produced from the hydrocarbon containing subterranean reservoir and the synthetic crude oil;
wherein the blended stabilized crude oil has a pour point at or below 30° C. and comprises at least 2 wt % of the synthetic crude oil.
