Embodiment
Oil refining enterprise is a primary raw material with crude oil and rock gas, produces products such as fuel, lubricating oil, paraffin, satisfies needs of society, seeks the maximum economic benefit of enterprise simultaneously.The flow process of oil refining is continuous production, and is large-scale, is made up of the unit operations module of many complex internal associations, referring to Fig. 1, forms different oil-refining chemical process flows by streams, energy stream and interconnecting of equipment between the unit module.
Device: the equipment combination that oil refining enterprise is produced products such as gasoline, diesel oil, kerosene, wax oil is referred to as device.The device of oil refining enterprise has: normal decompression, catalytic cracking, heavy-oil catalytic, hydrocracking, delayed coking, alkylation, reformation, hydrofining etc.
Time processing and secondary processing:, be divided into time processing and secondary processing usually with regard to oil refining process.Time processing refers to a crude distillation, by physical process, generates multiple finished product and these finished products such as gasoline, diesel oil, kerosene, wax oil by different boiling point cuttings, is referred to as straight run.Secondary processing refers to the cut that time processing is generated, and by chemical process, through finished products such as further processing gasoline and diesel oil, its objective is the raising light oil yield, for enterprise obtains bigger economic benefit again.
Oil product: finished products such as crude oil, gasoline, diesel oil, kerosene, wax oil, residual oil, and semi-manufacture (intermediate product), system is referred to as oil product.
Storage tank: storage tank is a container of storing oil and product.But its installation site of the classification of storage tank, use material, one-piece construction and oil product type are distinguished.
The tank field: storage tank needs by producing, and several, tens storage tanks are put together management, is referred to as the tank field.The tank field generally is divided into crude oil tank farm, tank field, centre (semi-manufacture), finished product tank field, raw material tank field, heavy oil tank field, liquefied gas tank field, petroleum gas tank field, lubricating oil tank field etc.
Receipt and payment: storage tank is given its various oil product by pipeline receiving trap or other storage tank and is referred to as " receipts ", and storage tank by pipeline oil product is picked auto levelizer or other storage tank is referred to as " paying ", and two operations are referred to as " receipt and payment " altogether.
Oil product moves: the production procedure of oil refining enterprise is continuous, and its material (liquid or gas) according to the conditions such as temperature and pressure that technological requirement provided physics or chemical change takes place in tower on the one hand, produces in pipeline again on the other hand and flows.The mobile of this material is exactly that oil product moves.
Side line: pipe laying is the important component part that the oil refining enterprise oil product moves.Pipe laying is made up of pipeline, valve, pipe support and various coupling.Between device and the device, between storage tank and the device, all be to interconnect between storage tank and the storage tank by pipeline, various oil products, as crude oil, product oil, semi-manufacture oil, petroleum gas etc., also all to carry through pipeline, thus the continuous production procedure of realization refinery.This pipe laying that links to each other with device, storage tank is referred to as " side line ".
Flow: in the pipe laying, what of the oil product (quality) that the unit interval passes through are referred to as " flow ".Special-purpose oil metering instrument is adopted in metering to oil product flow in the pipe laying, as differential pressure flowmeter (orifice plate), turbo flow meter, ultrasonic flow meter, mass flowmeter etc.Oil refining enterprise only trade settlement and significant points adopt high-precision mass flowmeter (measuring accuracy of liquid is 0.10% of a reading, the measuring accuracy of gas be reading 0.50%).
Jar amount: what of storage tank institute charge of oil product oil product (quality) are referred to as " jar measure ".Metering to the jar amount has in two, the one, adopt special-purpose tank level measuring instrument (as steel band type liquid level gauge, photoconduction electronic level instrument, radar type liquid-level gauge etc.), the 2nd, hand gauging metering (static weighing is the conventional metered dose method that oil refining enterprise metering handing-over and trade settlement are adopted).
Plan: main responsibility is to assign the production schedule (output, quality, energy consumption etc.) for each device in every month, and is responsible for each device is produced last month the statistics of (output, quality, energy consumption etc.).
Scheduling: main responsibility is the manufacturing program of a month of formulating according to planning authorities, take all factors into consideration the marketing information of production status such as crude oil, device, tank field and existing market, manufacturing program of a month is decomposed into (being generally five or a week) the scheduling of production plan of executable short period, and carries out production scheduling and scheduling of production according to this.
It is which to come where come and go how much what go in order in time to understand various components from that component is followed the tracks of, and accurately grasps the real-time status of enterprise's activity in production.The basis of oil refining chemical component tracing method of the present invention is:

(100+300/n (i-1)) * J4 (i-1): i-1 time period, the amount of contained gasoline component among the node J4 (being gasoline cistern 1).The 100th, the amount before 1 class of the gasoline cistern, the 300th, the amount of gasoline cistern 1 this class increase.
275/n * J1 (i-1): node J1 (i.e. south distillation) sends the amount of the gasoline component of J4 (being gasoline cistern 1) to.The 275th, class's output of southern distilled gasoline.
165/n * J2 (i-1): node J2 (being catalytic cracking) sends the amount of the gasoline component of J4 (being gasoline cistern 1) to.The 165th, class's output of catalytically cracked gasoline.
110/n * J3 (i-1): node J3 (being heavy-oil catalytic) sends the amount of the gasoline component of J4 (being gasoline cistern 1) to.The 165th, class's output of heavy-oil catalytic gasoline.
250/n * J4 (i-1): node J4 (being gasoline cistern 1) passes out to the amount of the gasoline component of J5 (being gasoline cistern 2).The 250th, the amount of gasoline that gasoline cistern 1 this class given gasoline cistern 2.
Carry out the calculating of each groups of nodes component of time period i by customer requirements, for example an order of classes or grades at school (8 hours) if one minute be a step-length, 480 goes on foot so totally.
The component tracking computer by working procedure, calculates " ratio " of component according to the algorithm principle of loop iteration, and then draws " amount " of component.
From above embodiment as can be seen, the foundation of oil refining chemical component tracker and the use of method can produce fairly obvious effect, obtain considerable benefit.
(1) follows the tracks of by component, in time " component " mobile quantity set becomes between handle assembly and storage tank, device and device, storage tank and the storage tank, the True Data that moves according to component (when from which, to which go when to finish, how many flows of this time period is), the total variances that is produced is decomposed each receipt and payment relation.This precision management to producing brings bigger economic benefit to enterprise.
(2) follow the tracks of by component,, make production manager can understand the logistics situation of enterprise timely and accurately,, be enterprise's enhancing efficiency by relying on tapping internal latent power so that reasonably allocate and utilize the various resources of production for the material balance of enterprise provides the support of True Data.
