West Texas Sand Supplier enjoys 16% down to 4% moisture content overnight

Moisture Reduction Systems installed a revolutionary new system to a major silica sand producer that supplies the Permian Basin’s oil and gas industry that transformed sand drying times.

BACKGROUND

The customer that operates multiple sites across Texas was conscious of the constant high operational cost of wet material requiring increased amounts of gas in the forced drying of the 100mesh material. Added to this was the high price of finding and drilling bore holes for new water to be used in the sand washing process.  The customer contacted Moisture Reduction Systems to provide a solution that will eliminate the high moisture in their material and deliver a subsequent cost reduction in the drying plant and water supply chain.

The average moisture level of the material was 14.00% moisture content with a typical natural drainage time to approximately 6.00% of up to 5 days.

CHALLENGE

  • Reduce moisture content to create significant cost reduction in the drying process
  • Provide water recycling aspect to the water removal process
  • Efficient and reliable operational use
  • Commercial viable and short time frame installation
  • Material sizing was 100 mesh

SOLUTION

Moisture Reduction Systems drew upon their significant knowledge and experience of the operational process and requirements at sand plants in order to design and install a bespoke- tailored solution that would deliver to the fast acting solution that was required. The system was installed to match exactly the stockpile footprint with individual sections installed so as to allow moisture reduction of the material to begin as soon as material had been placed on the large 270-degree radial arm area. Similarly, upon reclaiming of the material, the system could continue to operate on individual sections without compromising the yet to be reclaimed material.  The result was that the system delivered a final moisture level of 3% moisture content and in some instances 2.7% after 24 hours. This was in stark contrast to the previous 5 days to achieve 6.0%. Furthermore, the system recycled the removed water from the stockpile back into the wash plant at an average rate of 600 gallons per minute and 164m3 per hour. The customer ordered and implemented the system across its two other sites covering a total of 9 stockpiles.
