Embodiment 1

[0022] This example illustrates the situation where the device is used to blend -10# diesel oil with 0# diesel oil and pour point depressant as raw materials.

[0023] process such as figure 1 As shown, in the additive proportioning tank 3, the pour point depressant 1 is diluted with -35# diesel oil 2 at a volume ratio of 1:10, the dilution temperature is 40°C, and the diluted additive 5 is pumped into 0 by plunger pump 4. #Diesel oil pipeline 6, the oil in 0# diesel storage tank 7 is output by centrifugal pump 8 and measured by mass flow meter 9. The outlet pipeline 10 adopts electric heating and heat preservation, the temperature is 20-30°C, the flow rate of 0# diesel oil 11 and The flow rate of the additive diluent 5 is set according to a predetermined ratio. The additive diluent 5 and 0# diesel oil 11 are initially stirred by the centrifugal pump 12 and measured by the mass flow meter 13, and then enter the static mixer 14. After being fully mixed by the mixer 14, The col...

Embodiment 2

[0028] This example illustrates that the device is used to blend -20# oil with 0# oil, -35# oil and pour point depressant as raw materials.

[0029] process such as figure 2 As shown, in the additive proportioning tank 3, the pour point depressant 1 is diluted with -35# diesel oil 2 at a volume ratio of 1:10, the dilution temperature is 40°C, and the diluted additive 5 is pumped into 0 by plunger pump 4. #Oil oil pipeline 6, the oil product 11 in 0# oil storage tank 7 is output by centrifugal pump 8, measured by mass flow meter 9, additive dilution 5 and 0# oil 11 are first stirred by centrifugal pump 12, mass flow meter 13 Metering, the outlet pipeline 10 adopts electric heating and heat preservation, the temperature is 20-30°C, -35# oil 19 is output by centrifugal pump 20, and is measured by mass flow meter 21, the flow rate of -35# oil 19 and 0# oil containing additive diluent 22 The flow rate is set according to a predetermined ratio. After being fully mixed by the mixer...

Embodiment 3

[0034] This embodiment illustrates the situation when the device is used to improve the indicators of oil products with quality changes.

[0035] process such as image 3 As shown, the unqualified 0# oil product 11 in the 0# oil storage tank 7 is output by the centrifugal pump (8), measured by the mass flow meter 9, and the outlet pipeline 10 adopts electric heating and insulation, and the temperature is 20-30°C , Additive 1 is diluted with -35# diesel oil 2 in the additive proportioning tank 3, and the released liquid 5 is mixed with 0# oil 11 for the first time by centrifugal pump 12, metered by metering pump 13, fully mixed by static mixer 14, and online analysis instrument 15 Measure the inspection index of the oil product 16 after blending, and the computer control system randomly adjusts the ratio of the flow rate of 0# oil 11 and additive diluent 6 until the evaluation index after blending is within the set range. The blended oil product goes to the storage tank 17 and...

Abstract

The invention relates to a diesel oil storage device with a blending function. The diesel oil storage device consists of a diesel oil storage tank No. 0, a diesel oil storage tank No.-35 and a blending pump room, wherein, the diesel oil storage tank No. 0 is built under a surface frozen soil layer; the diesel oil storage tank No.-35 is a vertical cylindrical tank and is built on the ground; and the blending pump room is built above a heat tracing outlet end of the diesel oil storage tank No. 0 and is equipped with an additive storage tank, an additive thinning tank, a static mixer, an on-lineanalysis meter and a computer control system. The diesel oil storage device has the advantages that investment on oil depot equipment is reduced; according to weather and market changes, diesel oil No.0, diesel oil No.-35 and an additive can be rapidly blended into diesel oil No.-10 and No.-20; and in the case of possible changes of certain indexes of the diesel oil No.0 after long-term storage, the additive is simply added for blending so as to achieve the purposes of improving the indexes and further obtaining qualified diesel oil product.

Description

technical field [0001] The invention relates to a diesel storage device with blending function. Background technique [0002] In the "Petrochemical Industry Adjustment and Revitalization Plan" issued by the state in 2009, it was proposed to speed up the construction of refined oil storage facilities and seize the current favorable opportunity to increase the national reserve of refined oil. With reference to the practice of commercial storage of crude oil, research and formulate measures and systems for commercial storage of refined oil as soon as possible. The reserve is expected to reach 10 million tons in 2011. The two major oil companies, PetroChina and Sinopec, will be responsible for the construction of refined oil reserves, and the operation of the reserves will be managed by the central government. Experts said that the establishment of refined oil reserves will have a positive effect on stabilizing domestic oil prices and alleviating high inventories in refineries...
