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-line analysis 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
The present invention relates to a kind of diesel oil storage device with blending function.
Background technology
In " the petrochemical industry adjustment and development planning " of country's issue in 2009, quickening finished oil deposit Facilities Construction has been proposed, catch the current opportune time to increase the finished oil official reserves.With reference to the commercial deposit of crude oil way, research to develop commercial deposit way of finished oil and system as early as possible.Estimate that this storage level is expected to reach 1,000 ten thousand tons in 2011.PetroChina Company Limited. and two major oil companies of China Petrochemical Industry will be responsible for the construction of finished oil warehouse, and the operation of warehouse will be by central government's unified management.The expert represents that the foundation of finished oil deposit will produce positive role to stablizing domestic oil price and alleviating the high tank farm stock of oil refining enterprise.
China is large agricultural country, vast in territory, and the each department climate difference is big, there is evident difference in and situations each department big to the demand of diesel oil.Such as, China's southern area latitude is low, and annual temperature is substantially all below 0 ℃, and is very little even do not have to the diesel oil demand of the low trade mark; And the northern area of China latitude height, temperature is big and change fast with seasonal variation, big and trade mark switch speed is fast to the demand of low trade mark diesel oil, area, Heilungkiang for example, use No. 0 diesel oil and+No. 10 diesel oil summer, to autumn along with temperature reduces, use-No. 10 diesel oil gradually, switch to diesel oil-No. 20 along with temperature further reduces, then switch to diesel oil very soon-No. 35.Because-No. 10 diesel oil and-No. 20 diesel oil periods of service are short; generally have only 1 to 2 months; so following situation occurs through regular meeting: the refinery processes-No. 10 diesel oil and-No. 20 diesel oil when transporting to oil depot; because the unexpected variation of weather;-No. 10 diesel oil and-No. 20 diesel oil can't use; have to be stored into spring in the coming year, cause the waste of resource.
The index of most performance requriements of different trade mark finished diesel fuels is identical, and as sulfur content, ash grades; Have only part index number there are differences, as cold filter clogging temperature, so condensation point etc., oil depot can carry out simple relatively blending to some diesel oil, realizes the change of the diesel oil trade mark, reduces the kind that stores diesel oil thereby reach, and reduces the purpose of oil tank quantity.
Summary of the invention
The purpose of this invention is to provide a kind of diesel oil storage device, be fit to the northern area of China and use, can effectively reduce oil depot storage tank quantity, in time ensure market diesel oil supply with blending function.
A kind of diesel oil storage device with blending function of the present invention is made up of No. 0 diesel oil tank ,-No. 35 diesel oil tanks and blending pump house three parts, it is characterized in that:
(1) No. 0 diesel oil tank can be one or more, and at least one is built in below the ground surface ice soil layer, is for sleeping in jar of dished end, and the tank body napex is equipped with breather pipe, and breathing valve and flame trap are installed on the breather pipe; Built fireproof brickwork around the tank body; Tank base is equipped with some turnover oil pipes, and at least one oil outlet pipe and an oil inlet are furnished with the electric tracing facility; The outside pitching preservative coat of tank body, tank body steel plate inwall has anticorrosion coating.
(2)-No. 35 diesel oil tank is a vertical cylindrical tank, be built on the ground, and can be one or more, at least one storage tank outlet is furnished with the electro heat facility.
(3) the blending pump house is built in No. 0 diesel oil tank and accompanies hot exit end top, is provided with additive storage tank, additive thinning tank, static mixer, on-line analysis instrument, computer control system.
(4) described additive tank can store cold filter clogging temperature improving agent, kinematic viscosity improver, anti-oxidant stabilizer etc., wherein is mainly cold filter clogging temperature improving agent.Additive dilutes in storage tank.Additive dilutes by a certain percentage with-No. 35 diesel oil in thinning tank, and dilution ratio is 1: 10～100.The dilution temperature is 10～70 ℃, preferred 20～60 ℃, and more preferably 30～50 ℃.
(5) described on-line analysis instrument has the cold filter clogging temperature in-line analyzer, also can have to solidify and fix on line analysis instrument, kinematic viscosity in-line analyzer, cetane number in-line analyzer and flash-point in-line analyzer, wherein the cold filter clogging temperature in-line analyzer is topmost instrument, and the major control index is a cold filter clogging temperature.
Compared with prior art, the present invention has following advantage:
(1) can reduce even cancel-No. 10 diesel oil and-No. 20 diesel oil tanks, equipment investment reduces.
(2) can be according to climate and turn of the market, concoct out-No. 10 and-No. 20 diesel oil the guarantee market supply with stock's No. 0 diesel oil ,-No. 35 diesel oil and additive in time fast.
(3) No. 0 diesel fuel tank is in below the frozen soil layer, even like this under surface temperature is lower than 0 ℃ situation, No. 0 diesel oil still can not solidify, and need not can concoct its heating, has saved the blending energy consumption.
(4),, reach and improve index and make it up-to-standard purpose by simple adding additive blending occurring after No. 0 diesel oil long term storage of stock under the situation that some index (as cold filter clogging temperature, kinematic viscosity) changes.
(5) owing to have 0.06/ ton and 0.11/ ton of poor quality between No. 0 diesel oil and-No. 10 diesel oil ,-No. 20 diesel oil, can realize considerable economic by blending.Details is seen embodiment 1～2.
