Very small amounts of crude oil (7 – 100 ml) can be distilled with the B/R micro crude oil distillation system. The spinning band with a maximum of 15 theoretical plates can collect a number of fractions with good separation. Spinning band has low hold up and very high free space. This makes spinning band […]
True boiling point distillation distills crude oil from the initial boiling point up to 370-400 °C. D2892 is the ASTM test number. It is most commonly used to test crude oil and crude oil blends. It is sometimes used to distill condensate although that is outside the scope of D2892. The distillation typically takes […]
Not all Crude Oil is the Same. How can you do Quality Control? Refineries buy large volumes of crude oil. But when a 500,000 barrel tanker arrives, how do they know they are getting what they paid for? How do they know that it hasn’t been mixed or “cut” with low value compounds to increase […]
Butane Collection for True Boiling Point Distillation – ASTM D2892 Butane is a component of crude oil that boils well below room temperature. Its low boiling point requires special receivers to prevent loss of butane from the system. The receivers are cooled with dry ice or a cold finger style cooling system. There will either […]
True boiling point distillation has distillation column packing that has 15 theoretical plates of efficiency. Many different types of packing are currently available. There are two main categories of packing. Structured and random packing. Pro-Pak The most popular type of distillation column packing used is called Pro-Pak. Pro-Pak is made by the Cannon Instrument […]
