Separator Jetting – Slurry Dewatering and Disposal (post B-FSM-130)

Note: The subject of dewatering and disposal of produced solids will be covered in great detail in a future training module. Jetting systems are covered in Facilities Sand Management training Module M7, while Solids Dewatering, Transport, and Disposal are covered in Module M9. Below is an abridged version of the information specific to jetting system design. Further information can be obtained in whitepaper reference listed at the end of this blog post.

The purpose of Dewatering is to remove the free liquids associated with a slurry.

  • The goal is to achieve >90% volume reduction
  • The produced liquids are returned to process, instead of disposal

Keep system compact and simple – one or two step process

  • Single 6” urethane hydrocyclone at 15 psid for bulk dewatering
  • Filter-bag or filter-bin for final dewatering

Use filter-bag for open system and filter-bin for closed system

Next week I will start the discussion flowsheet design for jetting systems.
