Oil sand fluid coking system and method

Abstract

The invention discloses an oil sand fluid coking system and method. The fluid coking system includes a spiral heating and stirring feeder, a raising pipe fluid coking reactor, a settler and a regenerator; the spiral heating and stirring feeder includes a steam heating shell layer; the steam heating shell layer includes a gas inlet and a gas outlet; a spiral conveyer is arranged in the steam heating shell layer and provided with a feeding groove; the steam heating shell layer is connected to a motor and a frequency converter; the lower part of the raising pipe fluid coking reactor is connectedto the spiral conveyer, and the bottom of the raising pipe fluid coking reactor is provided with a spiral agitator and a pre-lifting steam inlet; the settler sleeves the upper part of the raising pipefluid coking reactor, and the bottom of the settler is provided with a stripping steam inlet; and the lower part of the regenerator is connected to the lower part of the settler through a to-be-generated inclined tube, the mid-upper part of the regenerator is connected to the mid-lower part of the raising pipe fluid coking reactor through a regeneration inclined tube, and the bottom of the regenerator is provided with an air inlet.

Description

technical field [0001] The invention relates to an oil sand fluidized coking system and an oil sand fluidized coking method, in particular to a method and device for an oil sand riser fluidized coking method. Background technique [0002] Oil sand, also known as tar sand or tar sand, belongs to unconventional petroleum resources. It is a kind of sand or sandstone containing bitumen or tar. It is a mixture composed of bitumen / tar, sand, minerals, clay and or water. The asphalt content is 3% to 20%, sand and clay account for 80% to 85%, and water accounts for 3% to 6%. Oil sand resources are widely distributed in the world, and the reserves are abundant. Oil sand resources account for 30% of oil reserves. my country is one of the countries with rich oil sand resources. [0003] Therefore, the effective processing and utilization of oil sands has great significance in energy strategy. There are currently two main types of oil sands processing options. One is to first separat...
