THE PROBLEM
Foam carry-over can cause upsets in operations and severe damage to gas compressors. In production, refining, and petrochemical processes, foaming can occur in:
|
|
Common techniques for foam detection include: DP gauges, capacitance probes, guided wave radar, electromagnetic radiation, neutron-backscatter, sonic echo devices, flow meters, and sight glasses.
Most of these do not offer early foam detection. These devices only detect foam after severe foaming has occurred and often not until the foam has upset downstream operations.
