Efficient Frac Sand Screening

A Frac Sand Producer was looking to increase production rates at an existing production plant. The product specification goal was to produce a consistent 40 X 70 API (American Petroleum Institute) standard product.  Feed to the Stack Sizer screening machines is from a processed material stream that discharges from a hydrocyclone at a solid feed rate of 150 stph.

Material testing was preformed at the Derrick Corporation test lab to confirm equipment selection required to make the 40 X 70 product. Derrick® recommended a two stage screening process using (3) Derrick Stack Sizers® to make the primary 40 mesh separation. The – 40 Mesh fraction from the primary Stack Sizers screening machines would then feed to (3) secondary Stack Sizers to remove the – 70 mesh particles.

The final product was within specification of the API standard within a single pass. All Stack Sizer units used the Derrick patented Polyweb® Urethane screen surfaces with high open area and long life expectancy of the panel. Stack Sizers have a high separation efficiency to increase product quality while reducing the variability in the final product output. The unique design of the Stack Sizer can save floor space while the minimal dynamic loading minimizes the structural requirements.
