Description

本発明は、連続した化学品製造プロセスから得られる、少なくとも１０重量％のＨＣｌ濃度を有する、特に少なくとも１ｍ３／ｈの体積流量での塩酸の使用を柔軟に制御するための方法を提供し、精製された塩酸は、選択的に、塩酸の引き取り場所である塩酸貯蔵所、輸送ステーション、ＨＣｌ電解ステーションまたはクロルアルカリ電解ステーションに供給され、または中和ステーションに供給され、１つまたは複数の上述の引き取り場所が故障した場合、または引き取り場所での引き取り障害の場合に、塩酸は中和ステーションに供給され、濃アルカリ金属水酸化物、特に濃水酸化ナトリウムで中和され、そして形成された塩溶液は、選択的にクロルアルカリ電解ステーションまたは廃棄ステーションに供給される。 The present invention provides a method for flexibly controlling the use of hydrochloric acid, which is obtained from a continuous chemical manufacturing process and has a HCl concentration of at least 10% by weight, particularly at a volumetric flow rate of at least 1 m3 / h. The hydrochloric acid that has been prepared is selectively supplied to a hydrochloric acid storage, a transportation station, an HCl electrolysis station or a chloralkali electrolysis station, which is a collection place of hydrochloric acid, or is supplied to a neutralization station , and one or more of the above-mentioned collections described above. In the event of a site failure, or a pick-up failure at the pick-up location, hydrochloric acid is supplied to the neutralization station, neutralized with concentrated alkali metal hydroxides, especially concentrated sodium hydroxide, and the salt solution formed. , Optionally supplied to the chloralkali electrolysis station or disposal station.

代替的に、塩化水素吸収のためにＨＣｌガス流４１をステーションＣに直接供給することもできる。 Alternatively, an HCl gas stream 41 can be supplied directly to station C for hydrogen chloride absorption.
