能产生氯化氫气体的化工品生产，都有哪些？

返回打印发布时间：2021/3/11 点击：11010

    在当前的化学生产领域，氯化氫气体是最大的副産品，對于大多數公司來說，排放廢氣也是頭疼的問題。能産生HCl氣體的化工品生産歸納如下：
    ⑴有机化学工业中的氯气流动反应会产生大量的HCl氣體。通常，企业利用冷却循环来吸收副产物盐酸，其含量低于33％。尾气被碱液吸收，产生盐水，最后排放污水。没有实现零排放，也没有循环经济。使用剩余的HCl氣體。
    ⑵在以盐酸为原料的有机和无机化学生产领域，众所周知，氯化氫是揮發性液體，HCl氣體在室溫下也會揮發，並與空氣中的水結合形成酸霧。特別是加熱時，揮發量是驚人的。使用鹽酸作爲原料的大多數生産過程都需要加熱。許多公司使用噴水吸收來處理含大量HCl氣體的尾氣。第二階段使用堿液吸收，最後排出鹽水。第一步吸收酸性水也無用，公司經常使用廉價的廢堿，石灰，石灰石等中和排放的廢水。
    (3)使用盐酸进行清洁和除锈的金加工公司和矿山，例如铝合金产品，铝箔产品，贵金属精炼，标准零件制造等，这些公司通常不处理任何无组织的排放，他们肯定会在将来有所改善。
    ⑷在干燥行业中，在高温下用HCl氣體或容易分解的物料干燥时所散发的尾气，这种尾气通常包含大量的水蒸气和少量的HCl氣體，一般企业也使用喷水吸收和中和废水排放，但是目前的环保要求非常严格，仅喷水吸收还远远达不到标准。如果吸收碱液的成本通常大于产品本身的利润，那么公司将负担不起。

Then suddenly all surmise and speculation was expunged from his mind, for no longer the clack of the typewriting machine came from next door. He heard the stir of a chair pushed back, and the rattle of a door handle. Norah was coming; who was of greater concern than all his thoughts about her.... And he was going to give her no quarter: she would have to introduce the subject of her feelings with regard to his niggardly hospital-subscription herself. He knew something of her pride from the affair of the book-plate, and he longed to see her take that armour off. "Found anything out, mate?" another officer asked. It is not intended to recommend writing down rules or tables relating to shop manipulation so much as facts which require remark or comment to impress them on the memory; writing notes not only assists in committing the subjects to memory, but cultivates a power of composing technical descriptions, a very necessary part of an engineering education. Specifications for engineering work are a most difficult kind of composition and may be made long, tedious, and irrelevant, or concise and lucid. From a quite small garden close to the palace a bronze gate with three medallions of lilies in high relief, of marvellous workmanship, opens on the Pearl Mosque, exquisitely white, at the end of its forecourt of immaculate pavement enclosed by a marble balustrade. Three polished and shining domes are supported by columns of snow made of a hard white marble, scarcely broken by [Pg 218]ornament, and carrying a roof hollowed into three vaults. The rings are still to be seen on the marble walls outside, to which, when the great Mogul came to prayer, curtains were attached made of gold net and spangled with diamonds and pearls. Sandy’s birthday dawned hot, but clear, with a good, steady south wind blowing. “Jeff calls it a ‘jinx’—a ‘hoodoo’,” responded Dick. “But the chef would discover it—they couldn’t be left there!” She was sitting in her room, sewing. Of late she had become domesticated, and she was fading under it. He had seen it already, and he saw it more plainly than ever just now. She looked up and smiled. Her smile had always been one of her greatest charms, because it was rare and very sweet. "Jack," she greeted him, "what have you done with the bread knife you took with you, dear? I have been lost without it." "Neither," drawled Cairness. "But Mrs. Lawton, here, has been good enough to tell me that you have known the exact truth about the Kirby massacre ever since a week after its occurrence, and yet you have shielded the criminals and lied in the papers. Then, too," he went on, "though there is no real proof against you, and you undoubtedly did handle it very well, I know that it was you that set Lawton on to try and bribe for the beef contract. You see your friends are unsafe, Mr. Stone, and I have been around yours and Lawton's ranches enough to have picked up a few damaging facts." The prince found in the Opposition in England the most unfortunate fosterers of his unfilial temper. Pulteney, Wyndham, Chesterfield, Carteret, Cobham, and, worst of all, Bolingbroke, became his associates, and the frequenters of his house. Fast ripening into a pattern of unfilial popularity under such influences, possessing some accomplishments, and a desire to stand well with the people, he married in April, 1736, Augusta of Saxe-Gotha, a princess of so much beauty and good sense, as might have reclaimed many a nature; who seems to have at least won the heart of her husband from his former romantic passion. It was an ominous circumstance, however, that the address of congratulation on this occasion was moved, not by the king's own Ministers, but by the king's own Opposition. Pulteney was the mover, and it was supported by two young men who that evening made their first speeches, and in them burst suddenly forth with that splendour which was destined to grow transcendent through many years. They were Pitt, afterwards Lord Chatham, and Lord Lyttelton. The Deacon had just remembered that he had not seen that individual for some little time, and looked around for him with some concern. It was well that he did. Shorty had come across the haversack that the Deacon had brought, and it awakened all his old predatory instincts, sharpened, if anything, by his feebleness. Without saying a word to any body, he had employed the time while the Surgeon and Deacon were in conversation in preparing one of his customary gorges after a long, hard march. He nearly succeeded. There was silence, in which a coal fell. She still stood with her arms outstretched; he knew that she was calling him—as no woman had ever called him—with all that of herself which was in his heart, part of his own being. "Why, my lord," said Luke, in reply to De Boteler's interrogatory, "there is hardly a free maiden in the parish that would not have been glad of Stephen; but, though I have never seen her, I am told this wife of his is the comeliest damsel between this and Winchcombe: and, besides, she is not like a common nief—and then, my lord, she is the sister of the good monk John."
