1 Making Crystal Slurry and Dry Crystals: cleaning fracture water for Oil and Gas drilling 1

2 Tyrone Environmental is involved in recycling water, plastics and rubber. We have teamed up with equipment suppliers of patented and proprietary systems to efficiently clean and recycle fracture water and salts in gas drilling. 2

3 You can choose whether you wish to remove and recycle as much water as possible, but before salt crystals form, which is called making saturated brine; or You can choose to remove even more water such that the you make a slurry with salt crystals; or You can choose to remove and recycle the maximum amount of water and dry the salt crystals 3

4 Recap: The amount of water you remove depends on what you wish to do with the water and contaminates in the water. Do you wish to create a … Saturated Brine or Crystal Slurry or Dry Crystal 4

5 Different equipment is required in the making of either a saturated brine, or a crystal slurry, or a dry crystal output Our focus here is on crystal slurry, or a dry crystal output 5

6 Recovering brine crystals require the solution to be processed in a Forced Circulation Crystallizer. (see slide #8) The Vapor Compression Cycle is integrated making an Ultra-Efficient Process. (see PowerPoint: Making Saturated Brine for details) 6

7 Vessel is designed for collecting and growing crystals. The solution containing both saturated brine and crystals is force-circulated downward through a stand-pipe where crystals have resident time to grow. The co-mingled solution is force-circulated through a centrifugal separator where brine and crystals are separated 7

10 The Co-Mingled solution has two components having different mass: Brine Liquid…lighter component circulates back to the vessel and Brine Crystals…heavier component discharges the system as a Wet Slurry. As Slurry cools, more crystals form and separate from the remaining saturated liquid. This liquid can be sent back to the Distillation & Recovery system for more dewatering, if practical. 10

11 Depending on desired dryness, Slurry can be post-processed by conventional means and equipment. 11

16 PRE-TREATMENT PROCESS Removes oil /grease, organics and iron Removes trace organics and non-desired inorganic constituents RESULTS: Effluent is clear and organic free High purity brine stream 16

17 Proprietary treated granular activated carbon 17

18 Features and Advantages: 1/2 penny a gallon or less in operating costs Ultra efficient energy consumption Closed loop system - water can be reused Closed loop system - no air emissions No membranes or no chemicals required Concentrate often has a commercial value Minimizes or eliminates sewer discharge Output surpasses EPA / Municipal requirements Fully automated, user friendly control panel Production materials can be recovered / reused 18 For more Details on this Technology see PowerPoint: Making Saturated Brine

19 a revolutionary and proprietary technology that efficiently separates large volumes of solids and liquids with different specific gravities The Voraxial® Separator acts as an in-line, continuous flow separator that can conduct a two-way or three-way separation Used to separate the salts from the slurry Voraxial

22 It is mobile and can be operated in the field You choose how much water you wish to remove, recycle, or dispose It eliminates the need to dispose of large volume of brine contaminated waste It provides resource recovery of brine combined with water recycling 22

23 Ecological Benefits Recycling Clean Water and Brine prevents contaminating the ground, ground water, or local POTW. Recovers valuable commodities that are otherwise contaminants. 23

24 24 D&R = DISTILLATION & RECOVERY Example #1

25 25 Only 3¢ to make sellable salt Tyrone D&R System is engineered to be more efficient than most Evaporation Systems

26 26 Example #2

27 27

28 28 COMMENTS: At each stage, (saturated brine, crystal slurry, and dry crystals) successive amounts of water is removed. 99% of the water is removed in the 15% Brine example (slide #26) If there is a market for clear brine, the more clear brine you can sell, the more revenue you generate and perhaps you will choose to stop at making clear saturated brine If there is no market for clear brine, you may wish to reduce your disposal costs by de-water to the maximum

31 CRYSTAL SLURRY LEASING $0.07 / GALLON PURCHASE $6.0 MILLION 31 SALT CRYSTAL LEASING $0.08 / GALLON PURCHASE $6.8 MILLION

32 32 Conclusion: With Crystal Slurry sales, the operator has new revenue of $3 - $4 Million. Under either scenario, there is either no, to minimum, deep well disposal.

33 33

34 Crystal Slurry, with sale value, ROI: ± 1 year Crystal Slurry, without sale value, Extends deep well life by a factor of 4 $2 Million well cost plus $4 Million System cost = $6 Million 500 bls vs daily disposal translates into Extended well life by a factor of 4 Dry Crystals, no deep well required, ROI: ± 27 years 34
