Dear All..

I am working in an LNG plant, our latest results of the lube oil analysis are showing some trends of having water content (high sodium) with ppm not exceeding 120ppm. Particles exceeded the OEM's recommended levels and one of the samples had a rating of 35 on QSA.

I have been requested to select the best technology available in the market to take care of the contaminants; Actually, I have decided to go for electrostatic filtration, but unfortunately, a problem has been raised just today from one of the engineers regarding the "unsafe" condition of the "high voltage" filtration unit in an LNG plant.

Given that:
- Water is highly suspected to be in emulsified or soluble form (from coolant leak)
- QSA Rating is not "TOO" high
- Particle counts let the oil sample to indicate NAS 8 level

What is the best technology to be utilized?

What are the Technologies adopted by the following companies:
Pall
Hydac
Internormen

Hello q-love

If you want the most effective, least complicated and most cost effective system for removing and controlling fine particulate, water, and varnish you should check out the CJC filter separator. The cost of providing explosion proof equipment can get very costly with most systems, however, CJC requirements are minimal or we can supply the pump with an air motor and a manual water drain and avoid these major costs completely.

If the sodium is disolved in the water, coalescing will remove it with the water, dehydrating will leave it in the oil.

Each CJC element holds 12 -16 pounds of varnish - using 4 - 16 or more elements - do the math, thats a lot of varnish!

Dirt capacties are similar see photo

To see how effective CJC filtration actually is check out this case study

Isopur is currently selling new MR units to a company that is replacing their Oilkleen units. They found their results were bad and the units were plagued with leaks. Call my office for more information.

Kleentek is our competitor, but we respect the work they have done in electrostatic cleaning above any other competitor. We feel our units are superior, but you would expect that of any company. The two companies use a different form of electrostatic cleaning. The primary difference is Isopur uses conventional filters for particle removal. The other companies remove particles inside their electrostatic device. In an Isopur machine, you change filters, not electrostatic chambers.

Isopur also has higher flow rates than the electrostatic cleaners, so our machines reach greater particle cleanup faster and we can overcome greater amounts of contamination ingress.

Much has been said in the press about ion exchange resins as a primary method of varnish mitigation. our customers have not had the results they expected using ion exchange alone. In several cases, the oil has been compromised due to a bad resin choice.
Ray, thats a great response, ISOPur has also done a lot for the varnish removal industry. We've found that improper media selection will result in immediate stripping of the additive system and may cause damage to the system. There are two patent-pending processes available that do this without stripping additives and the results are quite outstanding. Instead of taking months to clean up a system using electrostatic/agglomeration (and risk not actually lowering the varnish potential because the particles are in solution), it takes a few days. But, you’re absolutely right, improperly applying resin technology will cause more damage than good. If you’re evaluating a resin-based technology, ensure that you’re utilizing a patent-pending technology that has been proven to be safe on the fluid. Before I switched to this industry I was an end user for over 20 years. There have been a lot of false promises over the years that make my job very difficult. One thing to remember everyone, ask other users and demand a guarantee.

Wow! I am amazed at some of the comments on this posting.

Ray - Just to clear up a comment you made about replacing an older model OILKLEEN system. I assume that you are not replacing the OILKLEEN GREEN MACHEEN series electrostatic filtration system, because no GREEN MACHEEN leaks. Period!

DAVE (davgel)- Obviously you have no clue what you are talking about and I recommend that you do some research before you make a statement like this. OILKLEEN does not use Kleentek technology, and nor did Kleentek invent the current OILKLEEN technology used in the GREEN MACHEEN electrostatic oil cleaner. OILKLEEN has 18 electrostatic fields that the oil must go through and Kleentek has only 1. OILKLEEN has a higher field strength and also uses a depth media in the electrostatic field for additional filtration. I assure you will regret making this false claim...we will be in touch.

The OILKLEEN GREEN MACHEEN 300X is our explosion proof system that has a proven track record in the Middle East. Check out these varnish stripping results for real varnish removal proof of performance.
