Device for improving yield of neopentyl glycol in heavy oil

The utility model provides a device for improving the yield of neopentyl glycol in heavy oil. The device for improving the yield of neopentyl glycol in heavy oil comprises a heavy oil column, and a bottom end outlet of the heavy oil column is connected with inlets of column reactor pumps through a pipeline i. One part of outlets of the column reactor pumps are connected with an inlet of a reboiler through a pipeline a, and the other part of the outlets of the column reactor pumps are connected with an upper end inlet of a recycling tank through a pipeline h. A bottom end outlet of the recycling tank is connected with inlets of extraction pumps through a pipeline f, outlets of the extraction pumps are connected with a lower inlet of the reboiler through a pipeline d, and the upper portion of the reboiler is connected with a steam pipeline b. The reboiler is provided with three outlets, the lower outlet of the reboiler is connected with a lower inlet of the heavy oil column through a pipeline j, the middle outlet of the reboiler is communicated with a steam condensate collector, and the bottom outlet of the reboiler is connected with the inlets of the extraction pumps through a pipeline g. According to the device for improving the yield of neopentyl glycol in heavy oil, the bottom pipeline g of the reboiler directly enters the inlets of the extraction pumps, the content of neopentyl glycol in heavy oil can be lowered, and the yield of neopentyl glycol is improved.
