Technical field
The present invention relates to a kind of mancarried device of analyzing refinery feedstock or refinery practice product.
Background technology
For example feedstock analysis such as oil in test of crude is the important analysis that raw material must carry out before the refinery refining.The many different raw materials of the common refining of refinery comprise different crude oil and blends of crudes, they every kind all have many different important performances.In order to ensure the top condition of every kind of raw material of refining and evaluation Example as the potential value of raw materials such as available product yield, quality and value and for example corrosion or deposition etc. to as described in the potential impact of refinery practice of raw material, usually need to analyze a large amount of performances.And for example in chemical examination, can not measure burn into fouling or catalyst poisoning etc. usually, but can be from other performance estimation to the influence of refinery practice.
It is time-consuming analyzing traditionally, needs relative wide variety of materials, produces part analysis (chemical examination) data and need spend 1-2 week, produces the time of an a complete set of data cost up to 6 weeks.It is not abnormal thing that the raw material of buying does not have full assay data can offer the buyer, and therefore, the buyer must make many hypothesis to the value of raw material, for example for crude oil, can suppose according to the knowledge of the existing crude oil in similar area.This is for estimating new crude oil products, and particularly the crude oil from the new production area exists special risk.
If the refinery feedstock analysis is preferably the full assay data and can promptly offers the potential buyer, this will be favourable.
In addition, the express-analysis of process for refining product also needs.This product comprises the intermediate, pitch of whole refinery practice, subsequently as the product of the whole refinery practice of industrial chemicals with subsequently as fuel or lubricating oil or act as a fuel or product and the fuel (for example aero oil, gasoline, diesel oil and bunker fuel) and the lubricating oil itself of the whole refinery practice of the blending ingredients that lubricating oil is used.
The description of refinery practice and their product are all known those skilled in the art, for example in Ullmann ' the s Encyclopedia of Industrial Chemistry that is published by Wiley, the exercise question of being write by Walther W.Irion and Otto S.Neuwirth is the Zhang Zhongyou description of " Oil Refining ".
WO 00/39561 relates to a kind of crude oil automatic analysis method that uses spectroscopy.Although use the needed performance of crude oils of the spectroscopy energy many chemical examinations of express analysis, but the method for WO 00/39561 still needs a large amount of crude oil, use conventional distillation equipment and cost to analyze over 2 days, the infrared spectrum that is used to measure does not contain the information of the common needed all properties of oil in test of crude, and some performances will be determined with the secondary that degree of accuracy reduces greatly is related like this.
