CMM systems serve for inline dehydration and filtration of turbine oils for removal of free and soluble water and particulate matter.

Most frequently encountered contaminants in turbine oil are water and solids. These contaminants are detrimental to the performance and life of the oil. CMM oil purification plant are fully acceptable for removing of these contaminations.

WORKING PRINCIPLE

Input pump GP1 feeds the oil via mesh filter, heater and cartridge filter FP1 into the vacuum column VC, through oil sprayer. In the vessel, the oil flows down the filling, which consists of polyplopylene rings. The rings are supported by a mesh above the bottom of the column. The flow is adjusted by input pump bypass line and can be controlled by FM flowmeter. Oil temperature is controlled by thermistor, which provides signal to the control panel CC. The oil heater FH is equipped with a flow relay interlock, which prevents operation of the heater with no oil flow. When temperature reaches maximum, the heater automatically disengages and reengages when the temperature drops below minimal. The control panel CCalso starts and stops the pumps.

The vacuum pump VP ejects the air from the upper part of the column. Air enters the column through a trottle valve TV in its lower part. When contaminated oil flows on the rings, it forms a very thin oil film with constantly changing surface. Vacuum lowers partial pressure of water in the oil and the water in free or emulsified state quickly evaporates. The moisture is separated in the moisture separator filter FS. Purified oil accumulates at the bottom of the vessel and is sucked out through the cartridge filter FP2 by the output pump GP2.
