Tank Cleaner-20

Fatty Acid Oils/Fats (cleaning procedure)

Fatty acid oils/ fats will react with seawater as well as with untreated fresh water  and will format magnesium  and calcium soaps (white residues).  If possible seawater or untreated freshwater (high water hardness) should not be used for pre-cleaning.

1.  Butter worth the tanks 1-1,5 hour with a treated freshwater, which should be prepared in a separate tank.The  cleaning temperature should be approx. 20-25°C above the melting point of the product.  
For better result contact RX MARINE INTERNATIONAL. If the use of seawater cannot be avoided Butter worth the tank for 1-1, 5 hour with seawater of a temperature of 10 -15°C above the melting point of the product. After a sufficient pre-cleaning, the temperature can be increased to 20-25°C above the melting point of the product.

2.  If seawater was used in. 
3.  Flush the tank 10 minutes with fresh water to remove the residues of seawater.
4.  Prepare the following cleaning solution in fresh water:

• 0.4% RXSOL CTC-VOLC .
• 5% RXSOL AL 2005 Butter worth the tank 1.5 hours with the prepared solution. be recirculation. The temperature should be approx. 70-80°C.  

5.   Butter worth the tank for 1 hour with hot seawater (60-80°C)

6.  Flush the tank  with  fresh  water  Inspect  the  tank:  If  white residues are present  Butter  worth the  tank  with  on  of the   following solution:

• 3-5% phosphoric acid and 0.4% RXSOL CTC-VOLC ; or .
• 3-5% nitric acid and 0.4% RXSOL CTC-VOLC ; or. 
• 2-5% of a metallic brightener RXSOL  MB 1011 and 0.4% RXSOL CTC-VOLC The cleaning temperature should be moderate (50°C.) Use heating coils, not the butter worth heater.  

7.  Butter worth the tank 0, 5 hours with fresh water. 

8.   Ventilate, mop and dry the tank.

Tank cleaning operation
Slack Wax (Cleaning procedure) 

(Paraffin with a high oil content and a high melting point)

1. Steam the tank for approx. 1-1, 5 hour.The temperature should be at least 20°C above the melting point of the slack wax.
    
2. Butterworth the tank 1-1, 5 hour directly after steaming with hot seawater or hot fresh water.Let the water flow on deck until the required temperature has been reached. The temperature during the cleaning should be 20°C. above the melting point of the wax. The cleaning time should be sufficiently long to reach the melting point of the wax.
    
3. Due not interrupt the cleaning process and continue to Butterworth the tank with hotseawater or freshwater for another hour and inject the RXSOL-20-2044-210 (see method 3).Therefore mix the RXSOL-20-2044-210 into a drum with water (1 to 2 pails/100 litres water) and inject the mixture simultaneously into the Butterworth line during cleaning. The necessary amount to be injected depends on the consumption and number of Butterworth machines.Calculate for 10-15 m3 of wash water 1 pail  of RXSOL-20-2044-210
    
4. Flush the tank with fresh water
    
5. Ventilate, mop and dry the tank.

Note: during cleaning there should be no ballast water adjacent to the tank

Vegetable oils are divided in:

•   Non-drying products
•   Semi-drying products
•   Drying products ( Sun Flower 
•   Fatty acids Non Drying Products
   

Vegetable and Animal Oils (Cleaning Procedure)

 1. Butterworth the tank with seawater or freshwater with a temperature 20°C. above the melting point of the product to be cleaned. After sufficient pre-cleaning of at least 1.5 hours the temperature can be increased. Drying and Semi-drying ProductsThese are oxidising products and through reaction with oxygen they will dry and harden. Tank cleaning should be executed as soon as possible after discharge. High temperatures (e.g. cleaning or steaming) and heated cargoes in adjacent tanks should be avoided.
 2. Butterworth the tank with cold to warm seawater or freshwater.If the product has a higher melting point Butterworth the tank with seawater or freshwater with a temperature maximum 10°C above the melting point of the product. After sufficient pre-cleaning of at least 1.5 - 2 hours the temperature can be increased. Fatty Acids or  vegetable/animal oils with high free fatty acid contentsee the cleaning suggestion of Fatty Acids.
 3. If seawater was used in step 1 it is of utmost importance to flush/rinse the tank with freshwater before cleaning as per step 3 is continued.   
 4. (Final cleaning)Prepare the following solution (A) in freshwater (see table):
 

• Solution A(emulsification) 0. 4 % RXSOL-20-2046-210 Butterworth the tank with the prepared solution for 1, 5-2, 0 hours by recirculation. The necessary temperature can be achieved / maintained by means of heating coils, cargo heat exchanger or Butterworth heater. Depending on the amount of product residues the solution can be used for 1 to 4 tanks.On some vegetable/animal oils it is recommended to saponify additionally the product residues (see
  table): Therefore prepare one of the following solutions (B or C) in
  freshwater (see table):
   
• Solution B 0.4 % RXSOL-20-2046-210 plus 2.5% Potassium Hydroxide (KOH) or Sodium Hydroxide (NaOH)
   
• Solution C 0.4 % RXSOL-20-2046-210 plus 2 - 5% RXSOL AL 2005

 5. continued Butterworth the tank with the prepared solution for 1, 5-2, 0 hours by recirculation. The necessary temperature can be achieved /maintained by means of heating coil (service tank) cargo heat  exchanger or Butterworth heater.If RXSOL-20-2046-210 is used the  cleaning temperature should be 60-70°C If Sodium or Potassium Hydroxide is used the cleaning temperature should be 60.C.If RXSOL-20-2046-210 Marine is used the cleaning temperature can be 70-80°C. Depending on the amount of product residues the solution can be used for 1 to 3 tanks.
 6. Butterworth the tank 1 hour with hot seawater
 7. Rinse the tank with fresh water
 8. Inspect the tank; if white residues or a white film is present (calcium/magnesium soaps or carbonate) Butterworth the tank with one the following solution: 3-5% phosphoric acid and 0.4% RXSOL-20-2046-210 (stainless steel only); or 3-5% nitric acid and 0.4% RXSOL-20-2046-210 (stainless steel only); or 5-10% citric acid and 0,4% RXSOL-20-2046-210 (also suitable for Epoxy Coatings) or 2% RXSOL-16-1011-025 Marine and 0,4% RXSOL-20-2046-210 (also suitable for Epoxy Coatings) The cleaning temperature should be moderate (50°C.) Use heating coils not the Butterworth heater.
 9. Flush the tank with fresh water
10.Ventilate, mop and dry the cargo tank.

Note: for vegetable oils which can be cleaned only by the RXSOL-20-2046-210 (Solution A) the final cleaning can be carried out by recirculation or byinjection (see method 3).

Remember 
1st Point : We must initially wash these tanks with ambient seawater. Never try to use hot sea water, the palm oil will become hardened on the coating and it will not be possible to remove this from the coating.

2nd Point : On completion of oil discharging as soon as  wash these tanks. If the terminal does not allow tank cleaning at berth, we can just introduce some water in the tank and recirculate it for few seconds in every few hours to keep the tank bulkheads moist.

In short terms Initially wash the tanks containing drying or semi-drying palm oils with ambient seawater (or fresh water) for 1-1.5 hours. And Keep the tank moist till the time tank cleaning is commenced.

Our Experience Shows that perfet cleaning can be achived by adopting 2 step cleaning method-

1st by applying Physical pressure Cleaning by using high pressure machine ( 8 - 9 Bar ) with cold water.

2ndly adopt Chemical cleaning of the tank, here again pl. note temperature plays very importan role during chemical tank cleaning.

Note : 1. Avoid high temperature during initial washing of drying and semi-drying palm oils

            2. Avoid Caustic based chemicals which can make your tanks white if heated to higher temperatures.
           3. Always Use fresh water for making the cleaning solution, uses of sea water entire heating coils have chances of hard solid salt deposits and salt deposits could become difficult to remove. But if uses of sea water for making the chemical solution is only option then during cleaning operation First, stop the steam in the heating coils at least 30 minutes before stopping recirculation. Finally rinse the tank with fresh water for 5-10 minutes immediately after chemical recirculation.
