| 摘要: |
| 根据胱氨酸生产工艺流程,在中和工艺前用减压蒸馏法回收HCl,回收的盐酸再用于生产,此法不会破坏胱氨酸,同时反应前后胱氨酸含量不损失,不影响以后的粗制、精制和成品. |

| Abstract: |
| HCl recovery by pressure-reduced distillation before neutralization was tested in cystine-producing procedure. The retrieved HCl could be used again to the production and harmless to cystine preparation. |
| Key words: hydrochloric acid recovery pressure-reduced distillation |
