Description
技术领域technical field
本发明涉及化学技术领域，尤其涉及一种新型的水合物抑制剂。The invention relates to the technical field of chemistry, in particular to a novel hydrate inhibitor.
技术背景technical background
各种低沸点的烃如甲烷、乙烷、丙烷和二氧化碳、硫化氢等存在于天然气和其他石油流体中，同时水也以不同的量与这些石油流体组分混合。在低温高压下，当这样的石油流体成分或其他水合物形成物与水混合时，可以形成气体水合物，这种气体水合物是水和轻烃等小分子气体形成的笼形晶体。在开采和输送天然气和其他石油流体过程中这些笼形水合物可能堵塞管路，给石油和天然气的开采或输送带来困难。例如在约1MPa的压力下，乙烷在低于4℃的温度下可形成水合物，在3MPa的压力下乙烷在低于14℃的温度下可形成水合物。而这些温度和压力对于生产和输送天然气和其他石油流体的许多操作环境而言并非不常用。Various low-boiling hydrocarbons such as methane, ethane, propane and carbon dioxide, hydrogen sulfide, etc. are present in natural gas and other petroleum fluids, and water is also mixed with these petroleum fluid components in varying amounts. At low temperature and high pressure, when such petroleum fluid components or other hydrate formers are mixed with water, gas hydrates can be formed, which are clathrate crystals formed by water and small molecular gases such as light hydrocarbons. During the exploitation and transportation of natural gas and other petroleum fluids, these clathrate hydrates may block pipelines and bring difficulties to the exploitation or transportation of oil and natural gas. For example, under a pressure of about 1 MPa, ethane can form hydrates at a temperature lower than 4°C, and at a pressure of 3 MPa, ethane can form hydrates at a temperature lower than 14°C. And these temperatures and pressures are not uncommon for many operating environments in which natural gas and other petroleum fluids are produced and transported.
传统使用甲醇、乙二醇等热力学抑制剂是通过改变水合物生成的热力学条件来避免和防止水合物生成。但是，此类抑制剂具有浓度高(10～60wt％)、耗量大、成本高和毒性强污染环境等缺点，已经不能满足诸如海上油气开采作业等要求。从90年代起国内外开始研究用低剂量的动力学抑制剂来代替甲醇等热力学抑制剂的使用。The traditional use of thermodynamic inhibitors such as methanol and ethylene glycol is to avoid and prevent hydrate formation by changing the thermodynamic conditions of hydrate formation. However, such inhibitors have the disadvantages of high concentration (10-60wt%), large consumption, high cost, and strong environmental pollution, which cannot meet the requirements of offshore oil and gas exploration operations. Since the 1990s, domestic and foreign studies have begun to use low-dose kinetic inhibitors to replace the use of thermodynamic inhibitors such as methanol.
发明内容Contents of the invention
本发明的目的在于提供一种高效的低浓度水合物抑制剂。The object of the present invention is to provide an efficient low-concentration hydrate inhibitor.
本发明的目的是通过如下技术方案实现的：The purpose of the present invention is achieved through the following technical solutions:
本发明水合物抑制剂是聚乙烯吡咯烷酮与二乙二醇丁醚(C10H22O4)的混合物，由该两种物质混合而成的。可以在上述物质的基础上添加电解质、可溶性醇类等改变反应液热力学条件的化学剂，所述电解质和可溶性醇类没有特殊要求，可按照现有技术标准确定。The hydrate inhibitor of the present invention is a mixture of polyvinylpyrrolidone and diethylene glycol butyl ether (C 10 H 22 O 4 ), which is formed by mixing the two substances. Chemical agents such as electrolytes and soluble alcohols that change the thermodynamic conditions of the reaction liquid can be added on the basis of the above substances. The electrolytes and soluble alcohols have no special requirements and can be determined according to existing technical standards.
通过对聚乙烯吡咯烷酮抑制水合物性能的研究发现，水合物生成反应之前，在反应物中添加聚乙烯吡咯烷酮和协同剂二乙二醇丁醚(C10H22O4)，这两种添加剂组合使用相对于单独使用来说，能够显著抑制水合物的形成。The research on the hydrate inhibition performance of polyvinylpyrrolidone found that before the hydrate formation reaction, polyvinylpyrrolidone and synergist diethylene glycol butyl ether (C 10 H 22 O 4 ) were added to the reactant, and the combination of these two additives Compared with using alone, it can significantly inhibit the formation of hydrates.
本发明抑制剂使用浓度低，加入到石油或天然气管道中时，两种物质相对于水的质量浓度可以分别在0.01％～6％之间变化。聚乙烯基吡咯烷酮和二乙二醇丁醚两者的配比比例要根据现场条件、抑制时间，结合经济性综合考虑，可以在0.1∶1～5∶1之间。The inhibitor used in the invention has a low concentration, and when added to oil or natural gas pipelines, the mass concentrations of the two substances relative to water can be varied between 0.01% and 6%. The proportion of polyvinylpyrrolidone and diethylene glycol butyl ether should be in the range of 0.1:1 to 5:1 according to site conditions, inhibition time, and economic efficiency.
本发明抑制剂使用压力在1MPa到30MPa之间。The working pressure of the inhibitor of the present invention is between 1MPa and 30MPa.
本发明抑制剂可以克服现有技术的缺点，方便地以低浓度混合在生产或输送的石油流体中，降低水合物晶体的成核、生长或附聚的速度。The inhibitor of the present invention can overcome the shortcomings of the prior art, and is conveniently mixed in the petroleum fluid produced or transported at a low concentration to reduce the speed of nucleation, growth or agglomeration of hydrate crystals.
