METHOD FOR RECOVERING HEAT QUANTITY OF NAPHTHA CRACKING CENTER

摘要

PURPOSE: A calorie recovering method of a naphtha disintegration company is provided, which can reduce used amount of the steam for boiling water to the saturation temperature. CONSTITUTION: A calorie recovering method of a naphtha disintegration company comprises a step of heat-exchanging water for the steam production and condensed water exhausted from the naphtha disintegration company; a step of removing oxygen existing in the water by supplying the heat-exchanged water for steam production to a deaerator(1) and boiling the water to the saturation temperature; and a step of producing steam by transferring oxygen-removed water to the steam boiler.
