Tank Cleaner-20

Chemical Tank Cleaning

Spraying –

The tank should be sprayed with BSOLV, and then left for 45 minutes.  After 45 minutes the tank should be butterworthed warm 50-60 o C for 30 minutes, followed by a 4 hour hot wash 80 – 85 o C, after which fresh water rinse and dry the tank.  All safety precautions must be taken whenever handling this product.

Re-circulation –

Sufficient BSOLV should be filled into the tank so that the cargo pump and butterworth machines function properly.  Circulations  should be carried out for at least 4 and ideally 6 hours and all areas of the tanks must be rinsed.  The tank MUST be at least cleaned to a good Water White standard and must be dry, before filling the Butyl Glycol.  If another tank is to be circulated, then the product can be directly transferred.  IF not, it can be returned to drums for further use at a later date.  Following the circulations, the same washing procedure is carried out as outlined above in the spraying section.

* Use a strainer at the pumpstack when circulating any solution.Tank Lining – Stainless / Zinc / Epoxy

Procedure for Use:-RXSOL-16-1011-210 is highly concentrate

Dilute in water (always use plastic jar and RXSOL-16-1011-210 should be added to water never add water to RXSOL-16-1011-210.)

Surface should be sound clean and free from oil, grease, dirt etc.

Before Application degrease and remove oily painted area, Then apply Metals Rust stain Brites Cleaner on the metal surface to get complete reaction of rust particle with metal bright till full dry the surface area. Repeat the metal bright 2nd times to get complete reaction of rusted surface. This will help to get solid chemically treated base for NEW PAINT COATING.

CONCENTRATION of Metal Bright : 10 to 40% for removal of light rust stain, while direct and neat Metals Rust stain Brites Cleaner required to dissolved heavy rusted stains.

Diluted materials apply on rusted area for 15 to 20 minutes then wash off with water repeat if necessary. (For stubborn rusted stains.)

Spraying Direction: – Using an empty / clean 210 liter drum, fill with 190 liter of fresh water and add 20 liters of Metals Rust stain Brites Cleaner This makes a 10% solution, which can be sprayed onto areas in coated tanks where rust stains are showing and over actual rusted areas. Once spraying is completed, wait 20-30 minutes and fresh water rinse with lots of water, if possible use butterworth machines for a more efficient result. This method can be used in stainless tanks to “freshen up” the look of the stainless materials. Make sure to rinse the tank very well, as residual detergent within the Metals Rust stain Brites Cleaner will show up in a Wall Wash.

Injection– Not suitable.

Re-circulation: – When hand spraying is inadequate (too much area to cover), prepare a 2% - 5% solution in the tank using fresh water, heat solution to 50o C, then circulate the solution through butterworth machines for 3 x 45 minutes drops minimum. When using fixed machine recirculate for a minimum of 3 cycles. Rinse out the tank using hot seawater 85o C for 2 hours making sure that there is no form remaining in the water at the pumpstack drain cock. After the hot wash, the tank must be rinsed with fresh water and dried.

Spraying – Following rough washing to a good Water White or better, apply dilute RXSOL ORG DICHLOR to 1 – 3% strength.  First wet the tank surface (spray with DI water), then spray all over with Bleach, wait 30 minute (but do not allow to dry) and then rinse very well with DI water, including the tank top towards the sump.  To ensure that you have covered all areas properly, this process should be carried out at least twice with good DI water.

Injection– no.

Re-circulation– Following rough washing  to a good Water White standard or better, apply dilute RXSOL ORG DICHLOR  to 1-3% strength.  Mix sufficient Bleach with fresh water in the tank and heat this mixture to 40 – 50 0 C, circulate through the drop line if fitted and than circulate through butterworth machine for 3 hours.  After re-circulation immediately warm butterworth to (500 C) the tank for 3 hours at maximum pressure, increase the water temperature to 80-85 o C after 45 minutes.  Check (by smell) that there is no Bleach remaining, then fresh water rinse and dry.

** When there are a number of tanks requiring re-circulation, it may be significantly more efficient to make up a large batch or number of batches that can be transferred on between  tanks as required.

* Use a strainer at the pump stack when circulating any solution.
