ArrMaz’ SandTec Silica Dust Control for Hydraulic Fracturing

ArrMaz is a specialty chemicals manufacturer and innovator of SandTec®, a silica dust control proppant coating technology that reduces respirable silica dust by up to 99%, to within OSHA’s new permissible exposure limit. SandTec is a U.S. Department of Agriculture (USDA) Certified 100% Biobased Product under the BioPreferred® Program.

  • Field results show effectiveness in reducing silica dust to within the Occupational Safety and Health Administration’s (OSHA) new permissible exposure limit.

    MULBERRY, FL – ArrMaz’s SandTec®, a silica frac sand coating technology, reduces respirable silica dust generated during hydraulic fracturing by up to 99%. In March 2016, the Occupational Safety and Health Administration (OSHA) issued a final rule requiring industries that generate respirable silica dust to reduce the amount of silica dust their employees are exposed to by 50% within five years. ArrMaz is already helping hydraulic fracturing operations quickly and easily meet the new silica dust exposure limit with SandTec.

    Since 2011, the use of silica sand proppant per well in hydraulic fracturing has been steadily increasing. Exploration and production companies have discovered that if they use more sand when performing hydraulic fracturing, they are able to increase well production. The sand helps prop open the formation, allowing hydrocarbons to flow more freely. The transfer of sand proppant, however, generates respirable silica dust which, when inhaled, can impact worker health if not handled properly.

    Since September 2013, OSHA has been evaluating new proposed regulations for respirable crystalline silica which it estimates affects almost 17,000 workers engaged in support activities for oil and gas operations. On March 23rd, 2016, OSHA announced their final rule on occupational exposure to respirable crystalline silica. The new rule reduces the permissible exposure limit for respirable silica dust to 50 micrograms per cubic meter of air effective June 23rd, 2016. The hydraulic fracturing industry has until June 23rd, 2018, two years after the effective date, to comply.

    The rule also requires that hydraulic fracturing operations use engineering controls as the first line of defense to protect workers against silica dust. The compliance deadline for engineering controls is June 23rd, 2021. As an engineering control, SandTec is more efficient than bulky mechanical systems (such as vacuum trucks and ventilation equipment) which are difficult to mobilize onsite, require significant space, present handling risks, and are time consuming and expensive to set up, maintain and break down. Mechanical systems also do not provide protection at all transfer points. SandTec solves these challenges by applying a microscopic coating to frac sand proppant to control and minimize silica dust generation whenever and wherever proppant is transferred.

    “SandTec provides continuous protection from silica dust starting from the sand mine all the way to the hydraulic fracturing wellhead. It is easy to apply with no drying or curing required, and is biorenewable and biodegradeable addressing environmental concerns. Field results show that it is effective in reducing silica dust to within OSHA’s new exposure limit. These characteristics make it the ideal solution for hydraulic fracturing operations to quickly and cost-effectively comply with OSHA’s final rule” said John Suldickas, Commercial Manager for Oil and Gas at ArrMaz.

    ArrMaz’s engineers and technical experts continue to work with companies in the oil and gas sector to customize the SandTec system to meet their specific hydraulic fracturing needs.

  • Mulberry, FL (June 15, 2017) — ArrMaz announced today that it has earned the U.S. Department of Agriculture (USDA) Certified Biobased Product label for its SandTec silica dust control proppant coating, which, when applied to frac sand, results in significant reductions in respirable silica dust across the hydraulic fracturing supply chain. The test result for SandTec indicates that its biobased content is an impressive 100%, earning ArrMaz the privilege of displaying a unique USDA label on the product that highlights its biobased content.

    The USDA Certified Biobased Product label displays a product’s biobased content, which is the portion of a product that comes from a renewable source, such as plant, animal, marine, or forestry feedstocks. Utilizing renewable, biobased materials displaces the need for non-renewable petroleum-based chemicals. Biobased products, through petroleum displacement, have played an increasingly important role in reducing greenhouse gas emissions that exacerbate global climate change. They are cost-comparative, readily available, and perform as well as or better than their conventional counterparts.

    “We are honored to have earned the USDA’s approval to use its Certified Biobased Product Label for SandTec,” said Paul Williams, VP of Technology and Innovation at ArrMaz. “SandTec’s certification under the BioPreferred program demonstrates ArrMaz’s commitment to working with the oil and gas sector to innovate environmentally friendly silica dust control solutions for hydraulic fracturing.”

    “We applaud ArrMaz Products, LP for earning the USDA Certified Biobased Product label,” said Kate Lewis, USDA BioPreferred Program. “Products from ArrMaz Products, LP are contributing to an ever expanding marketplace that adds value to renewable agriculture commodities, creates jobs in rural communities, and decreases our reliance on petroleum.”

    Third-party verification for a product’s biobased content is administered through the USDA BioPreferred Program, an initiative created by the 2002 Farm Bill (and most recently expanded by the 2014 Farm Bill). One of the goals of the BioPreferred Program is to increase the development, purchase and use of biobased products.

    According to a report that USDA released in 2015, biobased products contributed $369 billion to the U.S. economy in 2013 and support, directly and indirectly, 4 million jobs. The same report found that biobased products also displace approximately 300 million gallons of petroleum per year in the U.S., which is the equivalent of taking 200,000 cars off the road. The increased production of renewable chemicals and biobased products contributes to the development and expansion of the U.S. bioeconomy – where society looks to agriculture for sustainable sources of fuel, energy, chemicals, and materials.

    About the USDA BioPreferred Program and Certified Biobased Product Label

    The BioPreferred Program is a USDA-led initiative that assists the development and expansion of markets for biobased products. The BioPreferred Program is transforming the marketplace for biobased products through two initiatives: mandatory purchasing requirements for Federal Agencies and Federal contractors and voluntary product certification and labeling.

    Biobased products span a diverse range of applications, such as lubricants, cleaning products, chemicals and bioplastics. The USDA Certified Biobased Product label communicates a product’s biobased content.

    Expressed as a percentage, biobased content is the ratio of non-fossil organic carbon (new organic carbon) to total organic carbon in a product. New organic carbon is derived from recently-created materials. The total organic carbon in a product consists of new organic carbon and old organic carbon that originates from fossil carbon materials, such as petroleum, coal, or natural gas. Approximately 2,800 products have earned the USDA Certified Biobased Product label as of August 2016.
