PROCESS FOR NEUTRALISING HYDROCARBON POLLUTION AND PRODUCTS THEREFOR |
| 摘要 |
18 A process for combating pollution caused by liquid hydrocarbons involves spreading partially dehydrated calcium sulphate over the slick. The calcium sulphate is prepared by dehydrating natural gypsum at between 100.degree.C, and 170.degree.C, suitably for 1 to 4 hours. It is preferably in a particulate form, the majority of particles being from 1 to 100 ? in size.
