At present, the natural gas energy is widely used in our country, each big oilfield is actively exploiting the natural gas, but the natural gas contains a large number of sulfurous substances, this kind of acidic substances is harmful to the environment. In this paper, how to use the chemical method to purify the natural gas by desulfuration was studied.%当前，我国天然气能源被广泛应用，各大油田积极在开采天然气，而天然气中含有大量的含硫物质，该种酸性物质有害环境，如何利用化学方法，高效有效的脱硫，净化处理天然气，是本文主要的研究点。
