1. System Description

The PSPI Model 45607AT Flash Point Monitor is an on-stream process monitor that measures the flash point of hydrocarbon products over a flash range of 10° to 121°C (50° to 250°F) and a viscosity range of up to 1000 SSU (220 CS). The analyzer robust design and measurement principle (no catalyst used in the measurement) delivers reliable measurements over time independently of fuel’s sulfur content. The Flash Point analyzer is completely microprocessor controlled with self-diagnostic capabilities, making it economical and simple to operate and maintain.

Applications Flash Point is one of the key final products specifications in the refineries. By having an online monitoring solution, refineries can optimize plants profitability while at the same time meeting quality requirements.

Methods Test results correlate with ASTM D-56 Tag Closed Cup test method. When measuring flash points above 79°C (175°F), analyzer results should be correlated with a laboratory analysis by ASTM D-93 Pensky-Martins Closed Cup test method or a similar laboratory test method.

Theory of Operation

Sample and air are fed to the measurement enclosure where they are mixed and fed into the Flash Cup Assembly. The mixture flows past a cartridge heater and a liquid space RTD sensor into the base of the flash cup. Excess liquid overflows to drain while the fuel-air vapors rise past a splash shield, vapor-space thermocouple, and high voltage electrodes before venting to drain.The temperature of the fuel-air mixture is slowly increased while a high voltage electrode circuit generates a spark. The vapor-space thermocouple is constantly monitored for a sudden rise in temperature. When flash occurs, the vapor-space thermocouple spikes. The sample temperature at the moment of ignition, as measured by the liquid space RTD sensor, is reported as the flash point temperature and a new measurement cycle is initiated. The flash point temperature is displayed on the monitor’s digital readout and is output as a 4-20 mADC signal.
