RYDALL HD HEAVY-DUTY DEGREASER
RYDALL HD is our new biodegradable, non-hazardous, citrus based, Heavy-Duty industrial degreaser. It is a water soluble, non-butyl, non-phosphate, non-corrosive, emulsifier.
RYDALL HD Heavy-Duty Degreaser is our new biodegradable, non-hazardous, citrus-based, heavy-duty industrial degreaser. It is a water-soluble, non-butyl, non-phosphate, non-corrosive, emulsifier. This innovative product is used specifically on hydrocarbon-based derivatives that are found on the oil or process side of the equipment, simply by circulating through the equipment.
RYDALL HD HEAVY-DUTY INDUSTRIAL DEGREASER APPLICATIONS
- Heat exchangers
- Rig wash
- Tube bundles
- Oil coolers and other hydrocarbon contaminated equipment.
- Pulp and paper
- Plastics or similar industries
- Fast: Reduce process equipment downtime resulting in more profits due to increased operating time.
- Safe: Utilize metal compliant chemistries to effectively remove fouling deposits down to bare metal.
- Easy: Does not require disassembly of equipment, thus saving labor, time and money for the plant.
- Simple: Non-toxic, easy to handle, and able to be applied by your own plant personnel.
- Biodegradable: Product is expected to be readily biodegradable.
- Isolate and drain the oil or process side of the exchanger to be cleaned.
- Install valves between the isolation flanges and the heat exchanger on both the supply and return. On larger volume applications, we recommend a 2” inlet/outlet as a minimum. The larger the valves and hosing, the better the flow and performance of the RYDALL HD heavy duty industrial degreaser.
- The same principle applies for the circulation pump as with the valves and hoses. We recommend a 90-140 GPM (340-530 LPM) flow rate for the RYDALL HD heavy duty industrial degreaser circulation pump. The better the volumes and flow rates of the pump, the better the performance of the cleaning solution.
- Generally, the circulation system described above, will circulate the RYDALL HD heavy duty industrial degreaser from a tote or Baker tank, to a high flow rate pump, to a plate and frame steam heat exchanger (to elevate the temperature to between 140-160ºF (60-71ºC)), in through the bottom of the equipment and out through the top, and finally back to the circulating tank.
- Ascertain the proper quantity of RYDALL HD heavy duty industrial degreaser for this particular job. Most applications require between 25-50% aqueous dilution of the total volume of the equipment or system to be cleaned.
- Pump all of the required RYDALL HD heavy duty industrial degreaser into the exchanger. Once that is accomplished, begin to add water to the tank until a stable circulation is realized. Once the level desired to maintain circulation is reached, turn off the water supply.
- Continue circulating the solution for the recommended amount of time. The time required to completely clean your application will depend on the severity of the deposits to be removed and the system volume. As a general guideline, most applications will require between 3-6 hours of circulation. Heavy deposits or volumes over 1,000 gallons (3,785 liters) may require 6-10 hours of circulation. (Please consult with your RYDALL representative or our technical staff for the recommended circulation time). As the circulation progresses and the cleaning solution removes the deposits from inside the unit, the volume will increase. To account for the increase in volume, please add water to the circulation vessel, as needed.
- The cleaning solution exiting from the heat exchanger is filtered through a “balancing” tank, which basically holds a portion of the solution, letting the lighter hydrocarbons emerge and float on the surface, and the heavier hydrocarbons sit at the bottom of the tank. The “clean”, filtered solution that re-circulates back to the heat exchanger is drawn from the middle of the balancing tank. We occasionally use two inline industrial filters to separate the heavier particles when the infrastructure allows.
- Upon completion of the recommended circulation time, all of the solution should be pumped back into the Baker tank.
