Corrosion Prevention and Miscellaneous Notes of Wording Attachment: Specifications of Articles 1 1. General This code is applied to the design for the new construction project of ground steel storage tank yards in the storage and transportation system for the liquid feedstock, liquid products and the by product liquid materials of petrochemical enterprises, and it is also applicable to expanded and rehabilitation projects as a reference. For the design of ground steel storage tank yard for the oil depot, this code shall be used for reference. This code is not applicable to the design of lowtemperature and normalpressure storage tank yard for the liquid hydrocarbon. When implementing this code, the stipulations made in the relevant mandatory standards and specifications shall be plied with. 2. Selection of Tanks Capacity of tanks Number of storage days for the crude oil and various kinds of oils shall ply with the following provisions: 1. The number of storage days for the crude oil and feedstock oils shall be defined in accordance with Table . Table Number of Storage Days for Crude Oil and Feedstock Oils Ways for Delivery to Plant Number of Storage Days Remark Pipeline delivery 5 ~ 7 Railway transportation 10 ~ 15 Inland waterway and offshore water transportation 15 ~ 20 The total capacity of tanks shall satisfy the requirements for continuous operation and one cargo discharge simultaneously. Ocean transportation ? 30 Notes: ? In case there is transit storage, the capacity of its storage tanks shall be included in the total capacity. ? The number of storage days for the import materials or special materials should not be less than 30 days or more than 60 days. 2. The number of storage days for the intermediate feedstock oils shall be defined in accordance with Table 2 Table 2 Number of Storage Days for the Intermediate Feedstock Oils Category Number of storage days Feedstock oils of the units to be started up or shutdown for maintenance at the same time or those between the units of the plex plant 2 ~ 4 Feedstock oils of the units of plex plant not to be started up or shut down for maintenance at the same time or those between the units that are not in different maintenance groups 15 ~ 20 2 Category Number of storage days Feedstock oils between the units that are not started up and shut down for maintenance 7 ~ 15 Feedstock oils of the units for multiposition changingover operations Calculated on changingover period, the production time for each position should not be less than 3 days. Note: In case the feedstock of a certain unit is also the feedstock oil for the other units or it can be stored in the storage tanks used for the other oils, it is remended to take the lower limit for the number of storage days. 3. The number of storage days for the product oils shall be defined according to Table 3. Table 3 Number of Storage Days for Product Oils Designation of oils Ways for delivery from plant No. of storage days Gasoline, lamp kerosene, diesel oil, heavy oil (fuel oil) Pipeline delivery 5 ~ 10 Railway transportation 10 ~ 20 Inland waterway and offshore water transportation 15 ~ 20 Road transportation 5 ~ 7 Aviation gasoline, jet fuel, aromatics, military diesel oil, liquid paraffin, solvent oil Pipeline delivery 5 ~ 10 Railway transportation 15 ~ 20 Inland waterway and offshore water transportation 20 ~ 25 Road transportation 5 ~ 7 Lubeoils, oils for electrical appliances , hydraulic oils Railway transportation 25 ~ 30 Inland waterway and offshore water transportation 25 ~ 35 Road transportation 15 ~ 20 LPG Pipeline delivery 5 ~ 7 Railway transportation 10 ~ 15 Inland waterway and offshore water transportation 10 ~ 15 Road transportation 5 ~ 7 Petrochemical feedstock Pipeline delivery 5 ~ 7 Railway transportation 10 ~ 15 Inland waterway and offshore water transportation 10 ~ 15 Road transportation 5 ~ 7 Notes: ? The storage tanks the capacities of which shall be defined according to this table, consist of the product tanks, position tanks and blending tanks. ? In case there is transit storage, its capacity of tanks shall be included in the total capacities of tanks defined 3 according to the above table. ? When the delivery way is inland and offshore water transportation, the sum of the capacities of product tanks and blending tanks shall satisfy at the same time the requirements for the continuous operation and one cargo loading capacity. ? In case the product is delivered from the plant by the ocean transportation, it is remended the number of storage days shall not be less than 30 days but not more than 60 days. The sum of the capacities of product tanks and blending tanks shall satisfy at the same time the requirements for
