'''Freezing Point Process Analyzer''' is intended for use in the petrochemical industry. It serves to determine automatically the Freezing Point (FP) of liquid and transparent petrochemical products. Up to two product streams and a validation stream can be connected to the online analyzer. It is intended to monitor the quality of production in the process and also the compliance with mandatory specifications for aviation gasoline. For gasoils and diesel oils with Cloud Points (CP) at very deep temperatures you can use the freezing point process analyzer to detect the CP. | |||
For detection of the FP a sample is cooled down continuously under exactly defined conditions. As soon as the temperature of the sample has gone below a limit, small crystals appear. They disperse in the whole sample and make it cloudy. The temperature at a certain degree of cloudiness is called CP. By stopping the cooling process the crystals are melting. The sample becomes clear and transparent again. The temperature at which all crystals have melted is called FP. | |||
For the use of liquid hydrocarbons it is important to know their properties and characteristics at low temperatures as the fluidity of these substances greatly influences their pumping or filtering behavior. The FP is a measuring value required to control and adjust the production process and it is a necessary specification for obtaining permission to sell the product. | |||

Freezing Point Process Analyzer is intended for use in the petrochemical industry. It serves to determine automatically the Freezing Point (FP) of liquid and transparent petrochemical products. Up to two product streams and a validation stream can be connected to the online analyzer. It is intended to monitor the quality of production in the process and also the compliance with mandatory specifications for aviation gasoline. For gasoils and diesel oils with Cloud Points (CP) at very deep temperatures you can use the freezing point process analyzer to detect the CP.
For detection of the FP a sample is cooled down continuously under exactly defined conditions. As soon as the temperature of the sample has gone below a limit, small crystals appear. They disperse in the whole sample and make it cloudy. The temperature at a certain degree of cloudiness is called CP. By stopping the cooling process the crystals are melting. The sample becomes clear and transparent again. The temperature at which all crystals have melted is called FP.
For the use of liquid hydrocarbons it is important to know their properties and characteristics at low temperatures as the fluidity of these substances greatly influences their pumping or filtering behavior. The FP is a measuring value required to control and adjust the production process and it is a necessary specification for obtaining permission to sell the product.
