STORAGE TANKSThis resistance guide for Tank Linings covers following types of specifi cations to be used as internal linings in storage tanks:

1) CHEMICAL RESISTANCE EPOXY SYSTEMS for fuels and gasoline. The specifi cation is based on high chemical and water resistant epoxy resins. High durability with extensive proven track record. Acceptable temperature: For aqueous cargoes the maximum temperature for storage is 50C/122F. Non-aqueous cargos - the maximum temperature for storage is 65C/149F. Loading and discharging - short term - max 85C/185C Recommended specifi cation as per following: 3 x 80 micron HEMPADUR 15400 If a blast/holding primer is required HEMPADUR 15590 will be specifi ed

2) HIGH CHEMICAL RESISTANCE EPOXY SYSTEMS for fuels, gasoline, additives, and a wide range of chemicals: The specifi cation is based on special high chemical resistant phenolic epoxies and offer the widest possible chemical resistance among the epoxy linings. Acceptable temperature: For aqueous cargoes the maximum temperature for storage is 50C/122F. Non-aqueous cargos - the maximum temperature for storage is 90C/194F. Loading and discharging - short term - max 100C/212C Recommended specifi cation as per following: 3 x 100 micron HEMPADUR 85671 If a blast/holding primer is required HEMPADUR 85671 will be specifi ed

3) SOLVENT FREE - HIGH CHEMICAL RESISTANCE EPOXY PHENOLIC SYSTEM for petroleum- and bio-fuels, gasoline, additives, and a wide range of chemicals. Acceptable temperature: For aqueous cargoes the maximum temperature for storage is 45C/113F. Non-aqueous cargos - the maximum temperature for storage is 65C/149F. Loading and discharging - short term - max 85C/185C Recommended specifi cation as per following: 2 x 250 micron HEMPADUR 35760 If a blast/holding primer is required HEMPADUR 15590 or HEMPADUR 85671 will be specifi ed. 4) SPECIAL ZINC SILICATE SYSTEMS for a wide range of fuels and chemicals. Especially suited for storage of strong organic solvent. The specifi cation is based on inorganic ethyl silicate which provide the toughest base for a zinc lining. Acceptable temperature: For aqueous cargoes the maximum temperature for storage is 45C/113F. Non-aqueous cargos - the maximum temperature for storage is 90C/194F. Loading and discharging - short term - max 90C/194C Recommended specifi cation as per following: 1 x 100 micron HEMPELS GALVOSIL 15700 Use of blast/holding primer will not be possible with such system.

5) SPECIAL VINYL-ESTER SYSTEM for a wide range of liquids including organic and inorganic acids. The fi lm thickness and application details will be tailored to each individual project. Recommended specifi cations will be based on HEMPELS VINYL ESTER GF 35910 - dry fi lm thickness and number of coatings will be specifi ed on a case to case basis.

STORAGE TANKSTHE KEY TO READ THE RESISTANCE GUIDE

A fi eld marked with a plus (+) means that the lining is resistant against the cargo in its normal form at ambient temperatures. If a max. temperature is mentioned then this will be the maximum temperature at which the coating is resistant for long time exposure. If a letter is mentioned it is necessary to read and follow the corresponding notes below.The grey areas means that it is not recommended to store the mentioned cargo in a tank coated with the coresponding lining.

SPECIFIC NOTES

Note A: Hydrolysable and acid containing substances.Cargoes such as esters, anhydrides and halogenated compounds tend to hydrolyse in the presence of water and form organic and inorganic acids. Other cargoes, such as crude methanol or fermentation ethyl alcohol may contain acidic impurities. These acids can damage the Zinc silicate lining. The cargo can be stored in a zinc silicate lined tank provided:- The tank is completely dry before loading.- These substances contain less than 0.02% (200 ppm) water and their acid value is below 1 for acceptance- Water contamination during tank operations and storage is to be avoided.

Note B:Ether-alcohols and polyalcohols:These cargoes may contain impurities and may also oxidise to form acidic products. The cargo can be stored in a Zinc Silicate coated tanks provided the cargo contain less than 0.3% (3000 ppm) water and has an acid value of 0.1 or less.

Note C:Crude oils and certain derivatives:These products may contain acidic compounds, organics as well as inorganic. The cargo can be stored in a Zinc Silicate coated tank provided the cargo has an acid value of 0.4 or less and the pH of water concentrations at time of storage is above 6.

Note D:Fats, oils and derivatives:Animal or vegetable fats, oils and derivatives usually contain a certain amount of free fatty acids (FFA). At elevated temperatures or in presence of water the formation of FFA is accelerated, especially when the initial concentration of FFA is high.The cargo can be stored in the epoxy coated tanks provided no mineral acid is present, the acid value is below 20 (corresponding in most cases to a free fatty acid content below 10%) and the water content is lower than 1 % (10,000 ppm).

Note E:Zinc pick-up by sensitive cargoes:The lining is resistant to the cargo, but contamination of the cargo by metallic zinc may occur. The possible negative effect of zinc pick-up must be taken into consideration.
