The minimum volume for disengagement is set at a point in which liquid begins to carry-over. Since steam is free of solids it has a very low conductivity and other attributes that influence quality. You can find the min. volume for disengagement by raising the steam drum level and monitoring the steam outlet with a sodium analyzer or similar instrument. You will see a jump in reading when liquid is carried over.
Steam quality is set based on boiler type. All boilers should meet ASME guidelines to ensure safe operation.
