Lange Containment Systems, Inc.

Profile 20 - National Cooperative Refinery Association Brine Ponds #1 and #2 Conway, Kansas

The oil and gas fields of southwest Kansas provide high quality petrochemical materials. The underlying natural salt domes provide large storage areas. Salt water is pumped in and out of the salt caverns to adjust for the fluctuating product inventory. When this super saturated brine is pumped out it must be securely stored for future use and the protection of the surrounding farm lands. Lange Containment provided the 30 mil PVC and 36 mil Hypalon for Brine Pond lining systems at the National Cooperative Refinery Association facility in Conway, Kansas. The 36 mil Hypalon acts as the primary liner. This liner contains the brine material and prevents contamination of the soils and ground water. In the occurrence that the Hypalon liner is breached, the 30 mil PVC acts as a secondary liner. A leak detection system, positioned between the primary and secondary liners, notifies the operators and they can cease the use of the pond until repairs can be made.
