COLD water is recommended for drying or semi-drying oils to flush the tank as prewash. Chemical expert suggest that cold water should be carried out immediately after discharge of cargo to prevent hardening of oil residues. Otherwise if oil is nondrying then Prewash of the tank with hot water at 50˚C is good decision to achieve BEST cleaning result.
Using Procedure:-
First of all flush the system with cold water to prevent evaporation rates and polymerization then the most economical method of using RXSOL-20-2008-HCF is by direct injection followed by recirculation washing, using tank cleaning machines.
Spraying Method:-
Using HCF as delivered in drums, spray onto areas where residue remains following rough washing leave for 10-45 minutes (but do not allow to dry), then butterworth at maximum pressure and warm water 60oC for at least 3 hours, checking that there is no foam remaining in the final stages. Inspects tanks(s) and if desired result has been achieved fresh water rinse and dry.
**Make sure to take all safety precautions are followed when handling / spraying HCF**
Injection Method– not applicable.
Re-circulation Method:–
Fill tank with fresh water and heat up to warm 50oC . IF a drop line is available on the tank line system, then start to circulate the water and add the required amount of Caustic flakes and HCF to make a 2.5% solution. A stronger solution can be made, but be advised that too much Caustic and too high temperature will result in white powder all over the tank. Under normal circumstances, between 2.5% and 4.5% will be sufficient strength. If there is no drop line, then lower butterworth hoses into the tank from the pump stack header without machines attached and circulate through these hoses while you fill the solution material.
* Use a strainer at the pump stack when circulating any solution.*
Question : How to clean veg oil ?
Answer : Following step can be follows to clean VEG OIL...
Step 1
Don't expose empty tank in air. Try to keep cool temperature inside the tank. Remove any remaining oil residue by gravitational and manual stripping, If possible Dampen a soft, clean cloth or rag under cool to room temperature water. Wring the cloth. The cloth should be damp, not dripping wet.
Step 2
If posible Lay the dampened cloth over the vegetable oil. Push downward to absorb as much oil as possible. Do not rub or wipe the oil. Lift the cloth.
Step 3
Spray and Sprinkle Hydrocarbon Remover HCF over any remaining vegetable oil. HCF cleaner will emulsify the oil, Allow the product to complete reaction for approximately an hour.
Step 4
Then follow genreal tank cleaning manual of SHIP. Common addopted method for tank cleaning is as follows :::

Question : Why uses of alkaline cleaner prohibited to clean fatty acid contains substances like veg oil, Animal oil etc ?
Answer : Neutral HCF supplier and stockist at all Indian and UAE - Middle East Coastal. HCF Neutral chemical importance is to emulsify vegetable oils and animal oils and fats residue with less foaming effect. Chemically if you can understand oil and fat which contain FATTY ACID while the general cleaner is alkaline in nature which is resulting greasy mass oncoming contact with Fatty Acid and Alkali cleaning material. To avoid the formation of GREASE like substance inside the tank, it is very important to take care of an alkaline cleaner with such cargo. On the other hand HCF Neutral ( free from any kinds of alkali mixture ) emulsifying oils particle and makes water soluble to remove from zinc-silicate coated tanks surface.
HYDRAZINE TEST KIT is used for the determination of Hydrazine content level in the Boiler’s Water. The test must be performed when in the vessel’s Boiler Water Treatment used hydrazine ingredient to control rust and corrosion RXSOL-50-5022-025 / RXSOL-50-5007-025 / RXSOL-19-1541-025. This is an activated hydrazine solution (Hydrazine with a catalyst for faster reaction with Dissolved Oxygen,) and applied for marine and industrial Boilers in low, medium and high pressures.
We are Hydrazine Test Kit supplier in Ennore, Chennai, Mumbai, JNPT, Manglore, GOa, Kandla, Gandhidham, Sikka, Mundra, Kolkata, Haldia, Pirpav, Dubai, Sharjah, Fujairah.
Control of Hydarazine level in Boiler water is very important. As proper level maintenance protect metal machinery parts from corrosion, However, precautions must be taken to prevent excess dose of hydrazine chemical as excess hydrazine will begin to decompose at temperature above 200oC to form Ammonia.
Hydrazine is one of popular an alternative Oxygen Scavenger. It is very important to protect boiler components from feed boiler water corrosion.

Following the procedure above, the concentration in ppm of Hydrazine in the Boiler Water will be obtained. According to the Boiler’s working conditions, and the results obtained the dosage of Oxygen Scavenger / Hydrazine must be adjusted considering the dose chart. For effective boiler water treatment with Hydrazine and in order to avoid any problem of Oxygen corrosion, the test at the initial period of use of RXSOL Oxygen Scavenger must be performed every day. Once a small concentration of Hydrazine obtained in the Boiler water then the test could be repeated every 2–3 days.

Hydrazine Hydrate Amine used as Oxygen scavenger on ultra high pressure industrial sites
No oxygen is entering the boiler with the feed water when hydrazine is present in the water.
The objective is to maintain a hydrazine residual between 0.05-0.2 ppm depending on operating pressure and boiler designe. Actual consumption is determined under operating conditions. A normal dosage is approximately 1 ltr. per day, depending of system layout.
Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. Thus, it is used as an ANTIOXIDANT, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems.
Hydrazine is mainly used as a foaming agent in preparing polymer foams.
No oxygen is entering the boiler with the feed water when hydrazine is present in the water.

Cargo hold cleaning
For heavily soiled areas, a preliminary cleaning is required. If surface is heavily contaminated, higher concentrations of the product in water can be used. When used for spot cleaning, apply by hand spraying neat or prepare a 20% solution, and allow solution to penetrate soil for about 30 minutes before rinsing off with water. Always wash off before chemicals dry on the surface.
