ROCHEM ALKLEEN products are heavy duty alkaline cleaners, containing specially selected sequestrants, powerful synthetic detergents, alkaline salts and soaps, which enables rapid penetration and economical removal of oil and grease films by saponification and emulsification. Not corrosive to ferrous metals and epoxy coating, although should not be used with aluminum, magnesium and zinc silicate tank coatings.




ROCHEM ALKLEEN can be used in any of four equally effective ways depending on the availability of time, man power, heat and mechanical spray equipment. All methods require a dosage of 3 to 5 per cent Alkleen Liquid mixed in FRESH WATER, heated to a temperature of 130 oF 180 oF (55 oC to 85 oC) After surfaces are clean the tank should be drained and rinsed with either fresh or salt water.


1. Steam Soaking Method - this method will completely remove oil and fat from all tank surfaces, converting it to a milky emulsion which may be pumped overboard as it disperses freely in water. Man-hours are minimal by this method.


2. Hot Wash Down Method - this method is preferred when time is a factor. The omplete operation can be performed in about one-third the time. This method required more man-hours.

3. Hot Soaking Method - when time is not a factor this method can be used to remove oil and fat residue. Rolling motion of vessel provides agitation while on route from on port to another. Steam must be available to maintain the solution at a specific temperature.


4. Rotating Spray Method - in tanks equipped with rotating spray heads, ROCHEM ALKLEEN will greatly speed up cleaning operation, thereby reducing man-hours, steam and excessive equipment wear. Surface treated should be washed down afterwards with sea or fresh water
