【摘要】：为了满足油田三次采油对聚丙烯酰胺产品多样性的需求,满足其对产品质量的要求。在公司没有完全成熟的生产工艺的情况下,利用现有中分子量聚丙烯酰胺的生产技术,生产线不进行大的技术改造,不增加生产成本的情况下,通过优化工艺参数、更换部分新型催化剂来生产高品质高分子量聚丙烯酰胺产品。为了解决驱油用高分子量聚丙烯酰胺产品质量指标的一级品合格率偏低的问题(共有15个指标,分别是产品外观、固含量、粒度、粘均分子量、水解度、溶解速度、筛网系数、残余单体、水不溶物、过滤因子、粘度、特性粘数、剪切粘度保留率、稳定粘度保留率、静吸附粘度保留率),需要重新摸索出一套氧化还原剂配方和一套新的各个工序的工艺操作参数。从溶解配方、聚合反应、干燥工序工艺参数的调整、研磨油与分散剂的配比、研磨筛分工序操作参数的变更等方面进行优化。提高驱油用高分子量聚丙烯酰胺产品质量指标的一级品合格率,为油田提供更多更优质的表面活性剂产品,确保油田4000万吨的目标实现,也为了大庆炼化公司减少产品降等级所带来的经济上的损失。通过一系列试验,如:改变溶解液浓度、溶解液pH值、水解剂的量、氧化还原体系剂的量、聚合反应的初始温度、干燥器换热方式、干燥器风温风压、双层筛网眼的直径等11项试验,生产出的聚丙烯酰胺的分子量达到了高分子量产品的要求,产品的质量也得到了较大的提升,达到了本次试验预计的效果。
[Abstract]:In order to meet the demand of polyacrylamide product diversity and product quality requirement of tertiary oil recovery in oil field.Under the condition that the company does not have a fully mature production process, using the existing production technology of medium-molecular-weight polyacrylamide, the production line does not carry out a large technical transformation and does not increase the production cost, by optimizing the process parameters.Replace some new catalysts to produce high-molecular weight polyacrylamide products.In order to solve the problem of low qualified rate of the first grade products of high molecular weight polyacrylamide for oil displacement (there are 15 indexes, they are product appearance, solid content, particle size, viscosity average molecular weight, hydrolysis degree, dissolution speed, screen coefficient, etc.Residual monomer, water insoluble, filtration factor, viscosity, intrinsic viscosity, shear viscosity retention, stable viscosity retention,It is necessary to find out a new formula of oxidizing reductant and a set of new process parameters for static adsorption viscosity retention rate.The optimization was carried out from the aspects of solution formula, polymerization reaction, adjustment of drying process parameters, ratio of grinding oil to dispersant, modification of operation parameters of grinding and screening process, etc.To improve the qualified rate of the first grade products of high molecular weight polyacrylamide for oil displacement, to provide more and more high quality surfactant products for oil fields, and to ensure the realization of the goal of 40 million tons of oil fields.Also for Daqing Refinery and Chemical Company to reduce the economic losses caused by product downgrade.Through a series of experiments, such as changing the concentration of solution, pH value of solution, amount of hydrolytic agent, amount of redox system agent, initial temperature of polymerization reaction, heat transfer mode of dryer, air temperature and wind pressure of dryer,The molecular weight of the polyacrylamide has reached the requirement of the high molecular weight product and the quality of the product has been greatly improved, and the predicted effect of this experiment has been achieved.
