for analyzing the flash point of a product in a process comprising a steam stripper receiving a stream of material and receiving steam includes sensors sensing the temperatures of the material the steam and the product which provide corresponding signals other sensors sense the flow rates of the material the steam and the product and provide corresponding signals the pressure in the top of the stripper is also sensed and a corresponding signal provided apparatus samples the product and provides signals corresponding to at least two predetermined parameters of the product a circuit receiving the signals from the sensors and from the apparatus provide a signal corresponding to the flash point temperature of the product in accordance with the signals from the sensors and the apparatus application_number US 80951377 A description referring to fig1 there is shown a steam stripper tower 1 having n number of trays not shown and receiving a stream from a main tower not shown by way of a line 5 superheated steam is provided to tower 1 by way of a line 8 where tower 1 strips a hydrocarbon product from the stream and provides the product by way of a line 12 which is pumped by a pump 13 to storage a line 14 vents tower 1 to the main tower conventional type temperature sensors 17 18 and 19 sense the temperatures of the stream in line.
