| Abstract: | Corrosion inspection on 33 sets of equipment and 21 pipelines in the butadiene extraction unit showed that the main problems were as follows:main corrosion of the unit was acetic acid corrosion,there were cooling water/scale corrosion in the water cooler,and corrosion products were mainly Fe3O4 and Fe2O3.In view of these problems,reasonable anti corrosion suggestions were put forward. |
