  • Crude oil composition estimation method, absorption process simulation method in absorption and liquefaction system, process simulation method in recovery system, and method of producing absorption and liquefaction system
    Patent number: 10408811
    Abstract: A crude oil composition estimation method estimates a composition of crude oil for use in simulation of a material balance in an absorption and liquefaction system that absorbs vapors emitted from the crude oil with the crude oil. The crude oil composition estimation method includes: comparing a calculated concentration of a treated gas with a measured concentration of the treated gas; estimating, when the calculated concentration agrees with the measured concentration, that the concentration included in the crude oil is a correct crude oil composition; and repeating, when the calculated concentration does not agree with the measured concentration, a process of correcting the concentration included in the crude oil and then comparing the calculated concentration with the measured concentration, until the calculated concentration agrees with the measured concentration, and when they agree, estimating that the corrected concentration in the crude oil is a correct crude oil composition.
