摘　　要：在天然气开采、输送或回收中,普遍采用注入甲醇或乙二醇等热力学抑制剂的方法,以抑制或避免水化物在管线和设备中的生成。实现该工艺的关键设备是注甲醇泵。新近开发的QZB型系列气动微量注甲醇泵能有效地防止天然气中水分的低温凝结,具有节能、耐腐蚀、工作安全、运行可靠、不污染环境及操作方便等优点,既可实现天然气井井口注醇工艺,也可用于站内集中注醇,同时兼顾车载和地面固定安装两种方式,现场应用效果令人满意。In the oil and gas industry, a method for injecting such thermodynamic inhititor as methanol is applied commonly in order to inhibit or avoid hydration in pipeline and equipment. The methanol injection pump is the key equipment for carrying out this technology. The recently developed series QZB pumps, which are driven by compressed natural gas or air, can be used for preventing condensation of moisture in natural gas at low temperature. Being power saving, corrosion resistant, safe, reliable, and easy to operate, the new pump can not only carry out methanol injection at gas wellhead, but also accomplish concentrative injection of methanol in gas stations. The pump can be truck mounted or fixed on the ground. On the spot application shows that good effect has been achieved.
