1. A hydrocarbonaceous material upgrading method comprising the steps of:
inputting a hydrocarbonaceous feedstock that has diluent therein into vaporization equipment to generate a first bottoms, wherein said first bottoms is a vaporization bottoms that is substantially unpumpable at pipeline conditions and has a first viscosity, a first density, a vaporization bottoms weight, and a pour point; inputting said first bottoms into a reactor at an input rate; heating, at an operating pressure, and with a heater that is inside said reactor, said first bottoms to a reactor temperature and for a residence time, wherein said reactor temperature is from and including 720° F. to 760° F. and at least a first hydrocarbonaceous material constituent boiling point temperature; vaporizing, under said operating pressure, at least some of said first bottoms to produce a first mass of hydrocarbonaceous material vapor; producing, through chemical reactions, a second mass of hydrocarbonaceous material vapor whose condensation point temperature is equal to or less than said first hydrocarbonaceous material constituent boiling point temperature, wherein said first and second masses of hydrocarbonaceous material vapors have a combined partial pressure; generating a second bottoms having a bottoms viscosity that is greater than said first viscosity, and a bottoms density that is greater than said first density; admitting to said reactor a sparge gas that reduces said combined partial pressure of said first and second masses of hydrocarbonaceous material vapors in said reactor; removing at least a portion of said first and second masses of hydrocarbonaceous material vapors from said reactor through action of said sparge gas; forming a hydrocarbonaceous material condensate from said at least said first and second mass of hydrocarbonaceous material vapors; and removing said second bottoms from said reactor at a second bottoms removal, wherein said operating pressure is compatible with ancillary equipment that is external of said reactor, wherein the liquid mass amount of said second bottoms in said reactor depends on said input rate, said second bottoms removal rate, and the mass amounts of each of said first and second masses of hydrocarbonaceous material vapors, wherein said residence time is sufficient to allow at least some of said chemical reactions and is related to said reactor feed rate, said second bottoms removal rate, and to said liquid mass amount in said reactor, wherein said reactor is a continuous feed, single pass reactor, wherein said hydrocarbonaceous material condensate has a second viscosity that is less than said first viscosity, and a second density that is less than said first density, wherein said hydrocarbonaceous material condensate has a lower average molecular weight and lower average boiling point temperature than said second bottoms and said first bottoms, wherein the weight of said hydrocarbonaceous material condensate, relative to said vaporization bottoms weight, is proportional to said reactor temperature, said residence time, and said operating pressure, wherein said second bottoms does not meet crude oil pipeline specification, wherein said hydrocarbonaceous material condensate weight is at least 40% of said vaporization bottoms weight, wherein said second density and said second viscosity of said hydrocarbonaceous material condensate are each substantially independent of said reactor temperature and said residence time, and wherein said hydrocarbonaceous material condensate meets crude oil pipeline specification. |
