TYRONE ENVIRONMENTAL GRP.

Making Crystal Slurry and Dry Crystals:

cleaning fracture water for Oil and Gas drilling


Who we are l.jpg
WHO WE ARE:

  • 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.


Brine water choices l.jpg
BRINE WATER: CHOICES

  • 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


L evel of de watering l.jpg
Level of De-Watering

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


Equipment configuration l.jpg
EQUIPMENT CONFIGURATION

  • 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


C rystal slurry important l.jpg
Crystal Slurry: Important

  • 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)


Crystal slurry f orced circulation l.jpg
CRYSTAL SLURRY: Forced circulation

  • 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

FLOW DIAGRAM: EXPLANATION


Forced separation l.jpg
Forced Separation

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.


Dry crystals l.jpg
Dry Crystals

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


What we offer making crystals l.jpg
WHAT WE OFFER:Making Crystals

  • Portable and Modular System

  • Automatic operation

  • Minimal labor and minimal maintenance

  • Cost effective operating System

  • Buy or Lease Options

How we do it p re treatment l.jpg
HOW WE DO IT: Pre-treatment

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


Technology p re treatment l.jpg
TECHNOLOGY: Pre-Treatment

  • Proprietary treated granular activated carbon


Technology distillation l.jpg
TECHNOLOGY: DISTILLATION

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

For more Details on this Technology see PowerPoint: “Making Saturated Brine”


Technology crystals separation l.jpg
TECHNOLOGY: CRYSTALS SEPARATION

  • 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

RESULTS: FRACTURE WATER Clean water and salt



Benefits of our system l.jpg
BENEFITS OF OUR SYSTEM:

  • 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


Benefits of our system23 l.jpg
BENEFITS OF OUR SYSTEM:

Ecological Benefits

  • Recycling Clean Water and Brine prevents contaminating the ground, ground water, or local POTW.

  • Recovers valuable commodities that are otherwise contaminants.

RESULTS: ENERGY CONSUMPTION & COSTS

Only 3¢ to make sellable salt

Tyrone D&R System is engineered to be more efficient than most Evaporation Systems

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

Financial considerations l.jpg
FINANCIAL CONSIDERATIONS:

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.



Financial considerations34 l.jpg
FINANCIAL CONSIDERATIONS:

  • 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. 2500 daily disposal translates into

        Extended well life by a factor of 4

  • Dry Crystals, no deep well required, ROI: ± 27 years
