Coal-to-liquid product delivery system

Abstract

The invention discloses a coal-to-oil product delivery system, which comprises a normal pressure fractionating tower and a reduced pressure fractionating tower, the side wall of the normal pressure fractionating tower is provided with a normal first line and a normal second line, the tower bottom of the normal pressure fractionating tower is provided with a normal pressure tower bottom line, the output end of the normal pressure tower bottom line is communicated with the reduced pressure fractionating tower, and the side wall of the reduced pressure fractionating tower is provided with a reduced first line; the output end of the normal line is provided with a first delivery pipe and a second delivery pipe; the output end of the normal second wire is provided with a third delivery pipe and a fourth delivery pipe; the output end of the subtracting line is provided with a fifth delivery pipe and a sixth delivery pipe; the second delivery pipe is communicated with the fourth delivery pipe through a communicating pipe, the output end of the sixth delivery pipe is communicated with the fourth delivery pipe, and the output end of the sixth delivery pipe is connected between the connecting position of the communicating pipe and the fourth delivery pipe and the input end of the fourth delivery pipe. According to the delivery system for the coal-to-liquid products, the products can be delivered in a classified and segmented mode, and economic benefits are high.

Description

technical field [0001] The invention relates to the field of coal-to-oil production, in particular to an external delivery system for coal-to-oil products. Background technique [0002] Coal-to-liquids is a technology that uses coal as raw material to produce oil products and petrochemical products through chemical processing. The produced oil will pass through the atmospheric fractionation tower before being sent out, and the normal first line and the normal second line are extracted from the side of the atmospheric fractionation tower respectively to lead out the corresponding products. The bottom oil of the atmospheric fractionation tower enters the vacuum fractionation tower, and the The first-line, second-line and third-line are respectively extracted from the side of the fractionation tower to lead out the corresponding products. When the demand for the product changes, it is impossible to classify the product and send it out in sections, and the economic benefit of t...
