摘要： In a method of periodically heating a product separator of a plant for producing anhydride or maleic anhydride, a PA or MA product is deposited on cooling surfaces of the product separator. To melt the product, the cooling surfaces are indirectly heated by means of a heated liquid, which is circulated through the product separator. The liquid heat transfer medium is indirectly heated with steam in a heater for the heat transfer medium. At least during the time of the largest steam demand, most of that steam is taken from a steam accumulator, which is charged with steam supplied from the plant for producing PA or MA. The charging of the steam accumulator is effected to at least a substantial degree during the time in which the heater for the heat transfer medium is out of operation or is operated under a low load.

摘要： A mixture will involve a risk of explosion if a concentration limit is exceeded. For this reason only part of the liquid is admixed to the gas in a first mixing zone so that the concentration limit above which there is a risk of explosion will not be exceeded. In a second mixing zone, the remaining quantity of liquid is added to the mixture withdrawn from the first mixing zone and the explosive concentration is exceeded. That mixture, in which the gas and liquid are distributed as homogeneously as possible, is reacted in a reaction zone. The reaction zone directly succeeds the second mixing zone.
摘要翻译：如果超过浓度限制，混合物将会有爆炸危险。为此，在第一混合区域中仅将一部分液体与气体混合，从而不会超过高于其的爆炸危险的浓度限度。在第二混合区中，将剩余量的液体加入从第一混合区抽出的混合物中，并且超过爆炸浓度。气体和液体尽可能均匀分布的混合物在反应区中反应。反应区直接成为第二混合区。
