我厂原是生产碳酸氢铵的小氮肥厂,近几年通过一系列的技术改造,形成了20kt/a合成氨,8kt/a混甲胺和8kt/a二甲基甲酰胺的生产规模,经济效益有了大幅度的提高。
Our factory was originally a small nitrogenous fertilizer plant producing ammonium bicarbonate. In recent years, it has formed a production scale of 20kt / a synthetic ammonia, 8kt / a mixed methylamine and 8kt / a dimethyl formamide through a series of technological transformations. The economy Benefit has been greatly improved.
