High flash pressure
Thread Content
The high-vapor pressure remained above the acceptable level. Both valves leading to the flare were opened fully, but the high-vapor pressure was still high. Later, the valve of the heat exchanger in the high-vapor separator was opened, and the pressure dropped sharply; it never returned to its previous level. What could be the reason for this?
When water enters high-flash point water, the temperature is high and the water is in a saturated state; as the gases dissolved in this water precipitate, the water turns into steam and its volume increases. At this point, the high-flash point heat exchanger is activated to condense the steam, reducing its volume and thereby lowering the pressure.
Is the temperature after high-flash gas cooling (such as heat exchange with graywater) abnormally high?
Most of this high-flash vapor is water vapor; if it were to be released, the amount would be considerable. To reduce the pressure of such hot and pressurized water to such low levels, it is necessary to use a heat exchanger for proper control, so that most of the water vapor can be condensed. As a result, there will be less vapor, making it easier to manage
