Abstract
A blowdown pot is provided with an inlet pressure control valve through which the pot receives unwanted residue e.g., ash from a high pressure chemical reactor, and this reactor residue can thereby be continuously or semi-continuously blown out from the high pressure, high temperature chemical reactor into the relatively low pressure blowdown pot which includes means maintaining a liquid level therein minimizing steam flashing and vessel wear. At the same time the reactor residue is removed from the pot with a liquid overflow.
