Description

从原油中除钙的方法
发明背景
本发明涉及一种从原油中除去某些金属的方法。具体而言，金属为钙。
存在于原油中的钙会导致加热器和换热器结垢，并使得原油加工中采用的催化剂中毒。因而，与低钙原油相比，高钙原油价值较低。除钙的方法可增加这种原油的价值。本发明对于在耐腐蚀环境下加工高钙原油显得更有价值，其中，在实施本发明的方法时酸度增加不构成一种缺陷。
发明概述
本发明提供了一种从石油原料中除去带2价正电荷的金属的方法。该方法包括使原料与一种树脂接触，所述树脂包含羧基、磺酸基和/或膦酸基。在优选的实施方案中，金属为第Ⅱ族金属，特别是钙。发明详述
本发明提供了一种从石油原料中除去带2价正电荷的金属的方法。这些金属包括：钙、镁、锰和锌。钙是特别重要的。本发明的方法包括使原料与一种树脂接触，所述树脂包含羧基、磺酸基和/或膦酸基。这些金属可以是以下的几种形式，包括环烷酸盐、酚盐、氯化物或硫酸盐。
树脂可包含羧基、磺酸基和/或膦酸基。优选所述树脂为交联树脂，因而其不溶于原油中。适宜的树脂为磺化的苯乙烯-二乙烯基苯共聚物、甲基丙烯酸-二乙烯基苯共聚物、聚丙烯酸、聚乙烯基磺酸、磷酸化苯乙烯-二乙烯基苯共聚物、聚甲基丙烯酸和连接有亚氨基二乙酸基团的苯乙烯-二乙烯基苯共聚物。
树脂可以是所述石油原料通过其的树脂床形式；或者，树脂可悬浮于原油中，并在处理的最后阶段通过过滤或离心进行分离。处理过程的温度应足够高以降低原油的粘度，但应足够低以避免树脂分解。通常温度在50-150℃是令人满意的。
使用后，树脂可通过酸处理进行再生。
下述实施例用于对本发明进行阐明，但它们并不构成对本发明的限定。实施例1
反应装置为备有搅拌器和回流冷凝器的玻璃容器，该装置被浸在油浴中。向反应器中加入50g的Kome 6/1原油，其包含930ppm的钙、42ppm的锰和2.6ppm的锌。再向反应器中加入15.6g的磺化苯乙烯-二乙烯基苯共聚物，其商业名称为Amberlite IR-120，其容量为1.9毫当量/ml。
将混合物在70℃下搅拌7小时。然后，通过离心分离出固体，将处理过的原油中的金属进行分析。钙、锰和锌的含量分别降至107、4.9和0.9ppm。
红外光谱表明，在1708cm-1处相应于羧基的谱带的强度比未处理过的原油强，而在1600cm-1处相应于环烷酸盐的谱带的强度比未处理过的原油弱。这表明，金属为羧酸盐形式，金属除去后游离出羧酸。
我们相信发生了下述反应：实施例2
反应装置与实施例1相同，向反应器中加入50g的Kome 6/1原油。再向反应器中加入2.15g的甲基丙烯酸与二乙烯基苯的共聚物，其商业名称为Amberlite IRP-64，其容量为10毫当量/g。
将混合物在70℃下搅拌6小时。然后，通过离心分离出固体，对原油进行分析。钙、锰和锌的含量分别降至66、2.2和0.7ppm。
我们相信发生了下述反应：
Figure A9719851700061
实施例3
反应装置与实施例1相同，向反应器中加入50g的Kome 6/1原油。再向反应器中加入7.6g的磺化苯乙烯-二乙烯基苯共聚物，其容量为3.3毫当量/g，公知的商品名为Amberlyst XN 1010。
将混合物在70℃下搅拌7小时。离心分离出固体后，油包含147ppm的钙、9ppm的锰和0.7ppm的锌，即远小于未处理的Kome 6/1。
