Loss of bulk liquid petroleum products
Loss of bulk liquid petroleum products1 Subject content and scope of application
GB11085-89
This standard specifies the bulk liquid petroleum products (hereinafter referred to as (Petroleum products) unloading, storage, transportation (including railway, road, waterway transportation) retail losses.
This standard applies to market vehicle gasoline, lamp kerosene, diesel and lubricating oils, but does not include aviation gasoline, jet fuel, liquefied gas and other military oils.
When calculating the losses of various items in this standard, in addition to the containers and measuring tools must be certified and qualified, the relevant regulations of GB1884 and GB1885 should also be followed.

3 Nouns and Terminology
3.1 Loss| |tt||Loss is the general term for evaporation loss and residual leakage loss. The former refers to the phenomenon of quantity reduction due to surface vaporization of petroleum products when loading, unloading, storage, transportation and other operations are carried out in accordance with prescribed operating procedures in containers with good airtightness, or when retailing according to prescribed methods; the latter refers to the phenomenon of quantity reduction due to surface vaporization of petroleum products during storage During transportation and sales, due to the adhesion of the inner walls of containers such as vehicles and ships, the small amount of residual oil in the container cannot be discharged cleanly, and the unavoidable dripping and trace leakage cause quantitative losses.
3.2 Loss
The amount reduced due to loss.
3.3 Loss rate
The loss of petroleum products during a certain production and operation is the percentage of the weight involved in the production and operation. 3.4 Storage loss rate
During the static storage period of petroleum products, the monthly cumulative storage loss is the percentage of the average monthly storage amount. The monthly cumulative storage loss is the algebraic sum of the daily storage losses in the month; the monthly average storage is the cumulative number of daily oil storage in the month divided by the actual number of storage days in the month. When a certain oil tank has receiving and discharging operations during the storage period, the losses that occur during the receiving and discharging operations of the tank are not storage losses. 3.5 Transmission loss rate
When petroleum products are transferred between oil tanks through closed pipelines, the difference between the output volume and the received volume is the percentage of the output volume. 3.6 Loading (ship) loss rate
When loading petroleum products into a vehicle or ship, the difference between the output volume and the revenue volume is the percentage of the output volume, Note; Since there is currently no unified calibration method for the volume of oil tankers, Therefore, the measurement of shore tanks shall prevail: the loss rate of shipment is tentatively set as a fixed value. China Petrochemical Corporation approved on 1989-02-10 and implemented on 1990-03-01
3.7 Unloading truck (ship) loss rate
GB11085-89
Unloading oil from trucks and ships product, the difference between the unloaded oil volume and the revenue volume is the percentage of the unloaded oil volume. Note: Since there is currently no unified verification method for the volume of oil tankers, the measurement of shore tanks shall prevail; the loss rate of unloaded ships is tentatively set as a fixed value. 3.8 Transportation loss rate
When transporting petroleum products from place A to place B, the difference between the loading volume of the truck and ship before departure and after arrival is the percentage of the loading volume before departure. When two or more railway tank cars are transported in a batch, the loading capacity before departure is the sum of the loading capacity of each tank car before departure; the transportation loss is calculated based on one batch, which is equal to the algebraic sum of the losses of each car after arrival. 3.9 Barrel filling loss rate
The difference between the container output volume and the filling volume is the same as the percentage of the container output volume. 3.10 Retail loss rate
The difference between the reduction in inventory and the total retail volume during inventory counting is the percentage of the total retail volume. 3.11 Vertical metal tank
refers to a vertical metal fixed-roof tank built on the ground. 3.12 Floating roof tank
External floating roof and internal floating roof are approved.
3.13 Concealed fin tanks
refers to oil tanks built underground, semi-underground, soil and caves. Division of 4 regions
