2 ENERVAC SEAL OIL Vacuum Purification System Dehydrates Fiters Purifies De Aerates Degasifies Miions of gaons of good grade turbo-compressor ubricating oi are ost each year through rotary compressor seas. The Lubrication and Pant Engineers face today probems reated to suppy of new oi, increasing oi prices, and disposa of contaminated sea oi which represents an environmenta hazard. Picture a Pant Engineer who has just been advised a sea on one of his 27,000 HP Centrifuga Compressors is eaking abnormay. What makes the situation particuary aggravating was that the Compressor had just undergone a major overhau and another one wasn t due for at east eighteen months. We expect seas to eak, of course and have earned to ive with eakage rates of 5 to 10 gaons per hour. I guess no one reay thought too much about the cost invoved, regarding them simpy as the cost of doing business. They just bought new oi on a steady basis, both to accommodate norma eakage and to repace contaminated oi at frequent intervas. They certainy were going to protect their expensive Turbines and Compressors. The cost of a re-buid is so high that no one begrudged the cost of new oi. However, this new sea was eaking 30 gaons an hour and this caused the Pant Engineer to do some arithmetic. Figuring the cost for just this singe new eak, he came up with some astounding cost figures. With today s oi prices and the cost of paying a deaer to hau sour oi away, this singe eak was going to cost him more than $1, a day. When this is mutipied by the number of days in a year, it became apparent he had a six figure probem. This set him thinking about the norma 5 to 10 gaon an hour eakage he had become accustomed to. That was the eye-opener. They were pouring an enormous number of doars down the drain every year. To one degree or another, every Pant Manager faces this diemma and ike the foregoing Engineer, most pant men probaby don t cacuate the exact doars invoved unti a specia probem brings it to their attention; The obvious answer to this profit drain, of course, is to recaim the contaminated ois. The economics of the situation are so cear cut that the question naturay arises as to why the move by industry to recyce Sea Ois has been so sow in coming. The answer is equay cear. Unti recenty, avaiabe Recamation Systems have simpy not been abe to do the whoe job.

3 Fow Diagram VACUUM BREAK VACUUM VALVE COLLECTOR TANK OPTION A Description Of Process & Fow (See Fow Diagram) Oi is drawn to the inet ine due to pressure difference between atmospheric pressure and ow absoute pressure in the vacuum chamber. In the inet ine, oi passes through a strainer and an eectric heater. In instaations where the foregoing is not practica because of ocation of Purifier in reation to oi suppy, we provide Option S an inet pump and reief vave. Oi enters the vacuum chamber through specia chemicay-inert acceerator cartridges where soids are removed and retained. Water and voatie contaminants are boied off in vapour form. Dissoved air, ight hydrocarbons and other gases are aso removed and are drawn off with water vapours at the top of the vacuum chamber into the vacuum ine, and are discharged by the vacuum package. Purified oi fas to the bottom of the vacuum chamber to be removed by the discharge pump. The oi eve is controed by a direct operated foat vave in the vacuum chamber. In the event of faiure of the discharge pump, the contro vave shuts off at its maximum eve. The key to the process is the specia chemicay-inert acceerator cartridges in the vacuum chamber: First, their in-depth design structure aows free water to be rapidy separated from oi by coaescence even before it reaches the evaporation stage. Second, miions of gass fibers 3-10 micrometer diameter provide a arge tota surface area for exposure of the thin oi fim to the vacuum. Third, sharp points of the gass fibers promote fast reease of gases and vapors from oi. Fourth, the eements act as a fine fiter soid contaminants. The cartridges are easiy repaced and disposabe.

4 Fitration equipment, for exampe, is effective at removing soid partices, but can t remove water and gases. Coaescing Systems can remove water and soids partices, but are disarmed by the surface active additives found in most ois on the market today. Centrifuge Systems remove free water and heavy soids, but require frequent and expensive maintenance. Eary recamation systems then, simpy weren t cost-effective. The Purification industry kept working on the probem, spurred by the stakes invoved and the tremendous increase in payoff, caused by soaring oi prices. The breakthrough came as a resut of ogica reasoning, that since a singe technoogy can t do the whoe job, what about combining technoogies? Hence, the Enervac Sea Oi Purifier, combining the genesis of vacuum fash distiation with fitration and coaescent technoogies, to remove both heavy and ight soids, free and souabe water and free and soube gases... Recaim Costy a Sea Ois with VACUUM PROCESS without removing incorporated additives The most common contaminants of the sea ois, depending on the type of gas being compressed are: 1. Particuate matter which may originate from many sources. Residua system dirt, wear of the seas and other moving parts of machinery, corrosion, atmospheric dust and carbon generated on hot spots. 2. Water is a major contaminant, present in the majority of gases compressed and in steam turbine driven systems. 3. Products of oxidation resut from high temperature operation in presence of water, oxygen and meta partices acting as cataysts. Gums, varnishes and sudge are symptomatic of this contamination, high acid number (Neut No.) confirms it. Oxidized oi aso changes coor becoming darker. 4. Diution by ighter hydrocarbons, the range C through C6, is quite common in sea ois for natura and synthetic gas compressors. Sampes from some oi traps indicate diution content as high as 15-22% of ighter fractions by weight. This resuts in a marked reduction of oi viscosity and fash point. 5. Chemicay active gases. In compressor seas where oi is in direct contact with Ammonia, Chorine, and Hydrogen Sufide there is adsorption of gas in oi depending on: time of contact, gas pressure and percentage of active gas in the compressed mixture of gases. 6. Inert gases, Carbon Dioxide, Carbon Oxide, Hydrogen and Hydrocarbon gases are usuay harmess to oi, however if not extracted may cause fire hazard or in combination with water some system corrosion. Oi Sampe For Anaysis: We recommend you provide ENERVAC with a sampe of your contaminated Sea Oi for anaysis and processing. We wi return to you a processed sampe so you can do your own anaysis. Let us prove to you what the Enervac Vacuum Purifier can do. A minimum of 5 gaons is required for our aboratory work and processing.
