Mineral material for oil-water separation as well as preparation method and application of mineral material
The invention provides a mineral material for oil-water separation and a preparation method and application thereof. The mineral material comprises alpha-CaSO4. 5H2O, Cu-K alpha radiation is used for crystal form detection of the mineral material, the mineral material has a (110) crystal face, a (020) crystal face, a (400) crystal face and a (204) crystal face, and the relative intensity ratio of the (204) crystal face to the (110) crystal face is (0.03-0.35): 1. As the crystal face (204) has an oil-water separation effect, trace water in the emulsion can be rapidly fixed in gypsum crystal lattices, and finally efficient, rapid and stable oil-water separation is achieved through a low-speed centrifugation method. According to the preparation method, the industrial byproduct gypsum is taken as a raw material, the efficient oil-water separation material is prepared at low cost through controllable directional crystal transformation, the reaction condition is mild and green, the cost is low, the yield is high, the product purity is high, and reference is provided for high-value utilization of the byproduct gypsum and reduction of the water content of crude oil.
本发明提供了用于油水分离的矿物材料及其制备方法和应用。该矿物材料包括α‑CaSO4·0.5H2O，其晶型检测使用Cu‑Kα辐射，具有(110)晶面、(020)晶面、(400)晶面和(204)晶面，其中(204)晶面与(110)晶面的相对强度比为(0.03～0.35):1。因(204)晶面具备油水分离的作用，能够将乳液中的微量水分快速固定于石膏晶格之中，最终通过低速离心的方法实现高效、快速、稳定的油水分离。其制备方法以工业副产石膏为原料，通过可控定向转晶，低成本制备了高效的油水分离材料，反应条件温和绿色、成本低，产率高，产品纯度高，为副产石膏的高值化利用和降低原油含水率提供参考。
