[Q&A] Catalytic Coking Reformate Blending Version 20170810
Thread Content
Starting today, a [Q&A] activity will be held in the catalytic coking reformed oil blending section; we hope everyone will give their support. What is the distillation temperature? Answer: When determining the distillation range of oil products, it is the temperature of the gas phase indicated by the thermometer at the point where the distilled liquid reaches a certain volume percentage. static/image/hrline/line7.png static/image/hrline/line9.png static/image/hrline/line7.png Petrochemical sector – New ideas for energy savings: the “Creative Thinking” campaign (the second phase is in full swing) http://bbs.hcbbs.com/thread-1666758-1-1.html 2017: “My Technical Upgrades” in the coal chemical industry http://bbs.hcbbs.com/thread-1786290-1-1.html [Daily Question] Catalyst-based coking and reformation of refined oil products – 2017 summary thread http://bbs.hcbbs.com/thread-1811219-1-1.html
The distillation temperature refers to the temperature at which the side-stream oil is distilled or extracted from the main fractionation tower.
100 mL of the oil sample is placed in a standard distillation flask and heated at a specified rate; the temperature of the gas phase at the moment the first drop of condensate appears is known as the initial boiling point. Thereafter, as the temperature gradually increased and distillation continued, the temperature of the gas phase at the points when 10 ml, 20 ml, 30 ml, and so on up to 90 ml of distillate had been collected was recorded respectively; these temperatures are referred to as the 10%, 20%, …, 90% distillation temperatures.
Distillation temperature: 100 mL of the oil sample is placed in a standard distillation flask and heated at a specified rate; the temperature of the gas phase at the moment the first drop of condensate appears is known as the initial boiling point. Thereafter, as the temperature gradually increased and distillation continued, the temperature of the gas phase at the points when 10 ml, 20 ml, 30 ml, and so on up to 90 ml of distillate had been collected was recorded respectively; these temperatures are referred to as the 10%, 20%, …, 90% distillation temperatures. The highest gas phase temperature during distillation is the dry point.
When determining the distillation range of oil products, it is the temperature of the gas phase indicated by the thermometer when the distilled liquid reaches a certain volume percentage.
The temperature observed when the condensed liquid recovered in the measuring cylinder reaches a specified volume (till) during the determination of the boiling range of petroleum products under specified conditions.
The temperature observed when the condensed liquid recovered in the measuring cylinder reaches a specified volume (ml) during the determination of the boiling range of petroleum products under specified conditions. The temperature observed at an evaporation volume of 10 ml is called the 10% evaporation temperature (since the sample volume is 100 ml), abbreviated as the 10% point. The distillation temperature can be used to indicate the fraction composition and performance of the oil. Parameters such as the initial boiling point, 10% point, 50% point, and 90% point of gasoline, as well as its final boiling point, can be used to indicate respectively the engine starting performance, acceleration performance, power output, and the degree of complete evaporation of gasoline.
