摘要： A process, and a device system suitable therefore, for producing polycarbonates are provided. The process contains the steps of producing at least chlorine and hydrogen by the chloralkali electrolysis of alkali chloride, preferably sodium chloride, in aqueous solution; synthesizing phosgene from carbon monoxide and chlorine; reacting phosgene with diol to form polycarbonate; providing a cleaned carbon dioxide gas stream as a process product of a process containing the steps of providing a CO2 gas stream and purifying the carbon dioxide gas stream by removing secondary constituents; converting the purified carbon dioxide into carbon monoxide and hydrogen by means of an RWGS reaction, which carbon monoxide and hydrogen can be used as raw materials for the polycarbonate production.

摘要： The invention relates to a method for flexibly controlling the use of hydrochloric acid having an HCl concentration of at least 10 wt %, in particular at a volume flow rate of at least 1 m3/h, obtained from a continuous chemical production process (A). In the method, purified hydrochloric acid (54) from a hydrochloric acid store (E) is optionally fed to a dispatch station (H), an HCl electrolysis station (F) and a chloralkali electrolysis station (L), which are consumption points for the hydrochloric acid, or to a neutralisation station (G) in that if one or more of said consumption points (H, F, L) is not available or if there are bottlenecks at the consumption points (H, F, L), the hydrochloric acid (54) is fed to the neutralisation station (G) and neutralised with concentrated alkali solution (55), in particular with concentrated sodium hydroxide solution, and the resulting salt solution (56) is fed either to the chloralkali process station (L) or to a disposal station (M).
