Description
Technical field
The present invention relates to technical field of LNG, and in particular to a kind of delivery management system towards LNG.
Background technology
LNG is English liquefied natural gas（liquefied natural gas）Abbreviation.Main component is methane, public
It is the energy most clean on the earth to recognize.Colourless, tasteless, nontoxic and non-corrosiveness, its volume is about commensurability gaseous natural gas volume
1/600, the weight of liquefied natural gas is only 45% or so of consubstantiality hydrops., Er Qiefang very little to air pollution after its burning
Go out heat big, so it has its unique advantage compared to traditional coal and petroleum derived fuels.Because imported L NG contributes to energy
Source country of consumption realizes energy supply diversification, ensures energy security, and exporting LNG contributes to natural gas producing nation effective exploitation day
So gas resource, increase foreign exchange earnings, promote national economic development, thus LNG trades are just becoming the new focus of global energy markets.
LNG industrial systems include the processes such as gas extraction, pretreatment, liquefaction, transport, receiving station, storage and dispensing, and it substantially may be used
To be divided into upper, middle and lower trip three phases, its schematic diagram is as shown in Figure 1.
At present the country has 42 LNG manufacturing enterprises, LNG receiving stations 13, and average annual yield speedup is 28%.China's Industry
The Chinese LNG market researches that investigation net is issued are reported with prediction of the development trend（2016-2022）Think, LNG project energy
Reach the not enough problem of the current China's natural gas conveying capacity of effectively solving.Current domestic 99% natural gas is entered by pipeline
Row conveying, but the pipe-line construction velocity lag of China, and pipeline course is not enough, it is impossible to meet natural gas transportation demand.And LNG
Then can be by railway, highway and ship transportation, supply is flexible, and radiation scope is wide.In the case, accumulating can in a large number be saved
The LNG of space and cost will undoubtedly become prioritizing selection.
Liquefied natural gas is commonly used at home industrial gases fuel, shipyard acetylene gas alternative fuel, urbanite's fuel, vapour
Car fuel, peak regulation of urban duct natural gas etc..Wherein country's LNG Vehicle's quantities are about 1200, although domestic automobile-used LNG
Market is at the early-stage, but its later stage demand growth is powerful.In recent years, existing enterprise invests eye from simple peak regulation gas
Using LNG as the development and Application field of the railcar of fuel, pneumatic ship and corollary equipment.It is reported that, current three barrels of oil and extensively remittance
The a collection of companies such as the energy, the combustion gas of new Austria, the combustion gas of port China, China Resources combustion gas have subsequently entered LNG new-energy automobile research fields, and phase
Should be made that 3-5 builds LNG gas stations, production LNG public transport and the planning of heavy truck.And in LNG ship field, existing lake at present
Northwest (NW) basket, Beijing oil land, the Kunlun energy, the combustion gas of new Austria, many energy enterprises such as Fujian are extensively converged in the energy, Fujian to seize LNG ship
Oceangoing ship market and carried out the running of marine fuel oil to gas demonstrative project.
But in the current situation, but there are many deficiencies in LNG dispensings link, be embodied in following aspects：
1st, the LNG demand unit such as downstream LNG filling stations, combustion gas factory can not form linkage, all be according to from domestic gas situation people
Work upstream LNG dispensings unit sends dispensing demand, causes delivery cistern car effectively to be distributed itself LNG, causes combustion
Material is wasted.
2nd, the LNG demand unit such as downstream LNG filling stations, combustion gas factory can not in real time obtain LNG delivery cistern car positional informationes
And checked by map, it is impossible to it is enough that aerating preparation is carried out in advance according to vehicle gait of march and current location.
3rd, upstream LNG dispensings unit cannot obtain the LNG demand in current dispensing region, it is impossible to have to distribution vehicle
Effect dispensing is arranged, and causes remaining if there is LNG after the dispensing task for currently dispensing object is completed, it has to emit surplus
Remaining LNG, therefore produce huge waste.
4th, upstream dispensing unit driver cannot be according to the distribution of LNG demand unit location and respective demand in dispensing region
Itself distribution route is effectively planned, for newly-built gas demand unit cannot also carry out efficient navigation, therefore is wasted big
The time of amount and energy.
5th, LNG fuel ship in sea effectively cannot send filling request to LNG filling ships, and send the real-time position of oneself
Put, LNG filling ships also cannot effectively receive aerating request and the positional information of fuel ship, cause marine aerating inefficiency.
6th, LNG supervision unit cannot obtain the real time position and operation safe condition of LNG delivery cistern cars and filling ship, it is impossible to
Effective monitoring and commander are carried out to LNG delivery cistern cars and filling ship.
