Process for determining the API gravity of oil by FID |
摘要 |
The API gravity of an oil is determined by vaporizing its volatile and pyrolyzable components, measuring the ratio of the amount vaporized within a range of relatively high temperatures to the total amount vaporized and determining that the gravity of the oil being tested equals that of an oil which has a similar composition and which, when a substantially equal amount is tested under substantially the same conditions, yields a similar ratio of amounts vaporized at the same temperatures.
