Description
发明背景
用于地球上天然资源如石油、瓦斯和采矿提取物的生产和加工的淡水量是庞大的且仅次于用于农业的量。几乎所有的由地下自然资源产生的所得水需要某种形式的处理,之后才可以重新使用或排弃,甚至在其可被排放之前需要尽力去进行更明显的净化。目前,全世界每年产生估计为700亿桶的产出水。预计来自石油和瓦斯开采的产水量显著增加,原因是老化的油井产生更多的水/桶石油。同时,来自水力压裂和油砂的非常规能生产遇到预计将继续的强劲增长。对水短缺问题的日渐重视以及用水许可和排放要求的日渐严格的政府规章推动了努力改进产出水处理可选方法,以通过增加水再利用和有利排放来使排弃最小化。
产出水含有高水平的总悬浮固体(TSS),包括灰尘、沙子、粘土、细菌、不溶性盐、总溶解固体(TDS)、常见盐和总有机碳(TOC),包括溶解和乳化的油、脂、以及来自钻井操作的化学添加剂。TSS、TDS和TOC的相对数量根据水源、上游使用和自然生产周期在很大程度上变化。因此水处理的任何水平必须与所有三类污染物及其变化作斗争,使得无一单个单元操作能够作为一个总解决方案。因此必须设计分离单元操作的工艺系列(process train)以处理产出水,且处理程度取决于:1) 进水水质(TSS、TDS和TOC水平),和2)出水水质要求。出水水质继而通过水的下游目的决定:在水力压裂中再利用的水可能只需要去除TSS,而将产出水加工成清洁盐水需要除去TSS和TOC两者。送往市政再利用或排放的水必须针对所有三类污染物进行处理。
去除TSS通常是处理工艺中要执行的首要操作或首要操作之一。因此,该TSS的去除操作在TDS和TOC的存在下具有稳定性是有必要。虽然TDS一般都是温和的,但是产出水中发现的溶解和乳化的油/碳(TOC)可能会导致显著的污垢。因此,需要永久亲水性和疏油性(耐油性)膜,以使它们能够过滤高TSS、TDS和TOC的水,而不被游离和溶解的油弄污,因此从产出水中经济地除TSS。
发明概述
简而言之,在一个方面,本发明涉及一种用于处理含有溶解固体、悬浮固体、有机物或其组合的水的方法,所述方法包括使水与包括布置在膜基材上的涂布材料的涂覆膜接触,所述涂布材料包含衍生自式I化合物、式II化合物和式III化合物的结构单元:

在本发明的方法和膜过滤装置中与所述涂布材料一起使用的膜基材可以由聚合材料构成,包括但不限于聚四氟乙烯(PTFE)、膨胀聚四氟乙烯(ePTFE)、聚烯烃、聚酯、聚酰胺、聚醚、聚砜,聚醚砜、聚偏二氟乙烯、聚苯乙烯、聚乙烯、聚丙烯、(甲基)丙烯酸酯、聚氨酯、基于纤维素的材料及其组合。特别是,所述膜基材可以由ePTFE构成,更具体地说,为背衬有PTFE的ePTFE膜。
所述膜基材可以具有约0.01微米至约50微米的孔径。在一些示例性实施方案中,所述膜基材可以具有约0.01微米至约50微米的孔径。在其他一些实施方案中,所述膜基材的孔径可以为约0.1微米至约10微米。在某些其他示例性实施方案中,所述膜基材的孔径可以为约0.3微米至约2微米。
所述涂布材料可以通过任何合适的方法例如通过辊涂、浸涂(浸没)或喷涂施用到膜基材。可通过将共聚物组合物溶解在适当的溶剂中将其涂覆到膜基材上。例如,共聚物可以溶解在四氟丙醇或六氟异丙醇中且该共聚物溶液可用于涂覆膜基材。涂料组合物还可以包括稳定剂和/或活化剂。在适当的溶剂中的涂料组合物可施用于膜基材,使得该涂料组合物通过孔并润湿膜基材的表面。包括孔表面的膜基材的至少一部分可以涂有涂料组合物而孔未被阻塞。可随后通过加热膜基材使得所述共聚物流动和聚结以在膜基材形成涂层随后蒸发溶剂来固化涂料组合物。在一个实施方案中,采用浸没过程用涂料组合物涂布过滤膜。共聚物涂料组合物可在低负载百分数下施用在膜基材上,负载百分数例如为约0.1至约1重量%,以减少孔阻塞。这也可以根据膜基材的重量而变化。在一些实施方案中,所述涂料组合物包括约0.2重量%的共聚物。
在一些实施方案中,所述膜过滤装置可另外包括背衬材料。膜基材和背衬材料可通过本领域中公知的技术结合成一体。背衬材料的非限制性实例包括具有加强过滤膜所必需的强度且具有与膜一体地结合的能力同时不干扰膜的渗透通道的织造或非织造合成材料。合适的背衬材料可包括聚四氟乙烯、聚酯、聚丙烯、聚乙烯和尼龙。在一个示例性实施方案中,背衬为聚四氟乙烯。
所述涂覆膜可为微滤膜或超滤膜。涂层可以赋予微滤膜耐油性。通过将亲水性和疏油性结合到微滤膜,共聚物涂料确保油产出水(例如在非常规瓦斯和石油生产中所发现的油产出水)的过滤。涂有共聚物的微滤器可以用来排斥含油悬浮固体(例如灰尘和其他小颗粒)。如果不存在这样的涂层,则产出水中的油(例如,乳化油)通常将膜弄污并使得经济运行变得不可能。耐油微滤器使油滴和溶解油通过而不被它们弄污。共聚涂层也可以赋予超滤膜耐油性和斥油性。疏油性的涂覆超滤膜可以排斥油滴,以避免被油弄污。
根据本发明的方法处理的水可以为来自油砂、煤层气、非常规瓦斯、增强油回收、盐水含水层或采矿工艺的产出水。水可在分散相中具有油且水是连续相。例如,水可以是来自石油工业的产出水、在常规的或非常规的天然气生产中的产出水、或页岩气产出水。水通常可能包含水和烃(例如油)的混合物,且还可以包含含油悬浮颗粒和高水平的溶解固体(例如,溶解盐)。例如,水可含有1-1000ppm之间的范围内的有机成分。此外,例如,它可能含有在1-500ppm之间的范围内的游离、未溶解油,在500-200000 ppm之间的范围内的溶解固体,以及在1-2000ppm之间的范围内的悬浮颗粒。
在又一个方面,本发明涉及一种处理水的方法,其中在使涂覆膜与水接触之前将水与水可分散聚合物混合或用水可分散聚合物对水进行预处理。所述水可分散聚合物选自凝结剂、阴离子絮凝剂、阳离子絮凝剂、非离子型絮凝剂及其组合。
聚合凝结剂通常为具有相对低分子量(低于500,000)的阳离子材料。通常用作凝结剂的阳离子聚电解质包括聚胺或聚季盐聚合物,例如在美国再颁专利RE 28,807和RE28,807中描述的那些,由仲胺(如二甲胺)和二官能环氧化物(如表氯醇)的反应形成,以及聚-(DADMACS)。阳离子丙烯酰胺共聚物可以包括基于烯丙基三烷基铵单体如氯化聚二烯丙基二甲基铵(DADMAC)、氯化烯丙基三乙基铵或(甲基)丙烯酸烷基酯铵的阳离子重复单元。阳离子凝结剂共聚物中的阳离子重复单元的摩尔百分比通常为至少50%,且其他单体(如果存在的话)为中性单体,例如,丙烯酰胺。聚阳离子凝结剂的分子量优选至少为5000,也可以为约100,000或更高至约1,000,000。
聚合絮凝剂可以是阴离子、阳离子、非离子或其适当组合,例如阴离子与非离子,或阳离子与非离子。絮凝剂的分子量特别是约1,000,000至30,000,000道尔顿、更特别是12,000,000至25,000,000道尔顿、并且最特别是15,000,000至22,000,000道尔顿。阴离子絮凝剂包括阴离子丙烯酰胺共聚物,具体是丙烯酰胺和丙烯酸的共聚物。阳离子絮凝剂包括阳离子丙烯酰胺共聚物,该阳离子丙烯酰胺共聚物包括基于氯化烯丙基三烷基铵的阳离子重复单元。代表性的阳离子丙烯酰胺共聚物是丙烯酰胺和氯化烯丙基三乙基铵(ATAC)的共聚物。可存在于丙烯酰胺共聚物中的其他阳离子重复单元包括衍生自烷基(甲基)丙烯酰胺铵盐、(甲基)丙烯酸烷基酯铵盐、烯丙基三烷基铵盐和二烯丙基二烷基铵盐的那些。丙烯酰胺絮凝剂共聚物通常具有约50-95%摩尔、优选70-90%摩尔、更优选约80-90%摩尔的丙烯酰胺残基。非离子絮凝剂包括聚合物如聚丙烯酰胺、聚乙烯醇、聚乙二醇、聚吡咯烷酮、聚乙烯胺和多糖如纤维素,包括如WO 2007/047481中所述的活化淀粉。
除了凝结剂或絮凝剂,待通过根据本发明的膜过滤装置处理的水可以包括已知弄污现有技术的膜的其他物质,包括天然有机物(NOM),如腐殖酸、藻类有机物和细胞碎片、生物分子(如蛋白质和细菌)以及所有类型的表面活性剂。

实施例
通用程序
制备涂覆膜的方法
在2-丙醇中制备硅烷单体和交联剂的溶液,溶液的浓度使得涂布材料为所需量,涂布材料的所需量通常通过涂覆膜重量与未涂覆膜重量之间的差来计算,记作“wt% add-on(增加的重量百分比)”,wt% add-on= 100* (涂覆膜的重量-未涂覆膜的重量)/未涂覆膜的重量。
由0.16%重量的涂布溶液提供足够的材料以赋予膜所需的物理性能(亲水性和疏油性),同时在约5 wt% add-on时保持高水平的渗透率,该涂布溶液包括0.2%的活化剂溶液。活化剂溶液由在水:2-丙醇为3:1的水和2-丙醇中的0.93%的氢氧化钾构成。在加入活化剂溶液之前将溶液急冷以降低反应性,直至固化步骤。然后对膜进行喷涂或浸涂。
喷涂:将无背衬膜固定到载体,以确保均匀的张力,并防止被涂布溶液浸湿时的收缩或其他变形。涂布溶液喷在膜上以产生均匀的湿润,该润湿足以浸透膜,但在固化时不堵塞孔。对于实验室规模的涂层,使用压力为8 psi、通过喷嘴为1.4毫米的中央气动专业HVLP(Central Pneumatic Professional HVLP) 20盎司重力喷枪,要求喷射进行三道以获得完全覆盖而不过度涂覆。随后在90℃下、在排气式烘箱中将仍然在载体中的膜加热固化至少4-6小时以确保完全聚合。在用于过滤之前,使用台式挟辊(具有可调间隙设置的MarcatoAtlas 150意大利面制作器,设定为5-6档)将无背衬膜以物理方式层合到PTFE毡上,做法是,施加压力并可逆地将这两层层合在一起。
浸涂:将2.5 x 5英寸的矩形有背衬膜浸没在涂布溶液中并彻底浸泡以去除在背衬中的空气囊泡。随后将其从涂布溶液浴中取出,并使用台式挟辊(具有可调间隙设置的Marcato Atlas 150意大利面制作器,设定为5-6档)沥除过量的涂布溶液。然后将膜样片竖立在耐热架中以使传热最大化并在90℃下在通风烘箱中过夜固化以确保完全聚合。为了未来规模化的尝试,成功地进行了浸涂无背衬膜的初步可行性研究,其中无背衬膜固定于无孔背衬。对于实验室规模涂层,约12 × 12英寸的正方形Teflon片用作背衬且用间隔约0.5英寸的0.5英寸双面胶带小片沿着边缘紧固。然后,这些“带背衬的”膜浸没在涂布溶液中并且膜朝下通过压力为10 psi且速度为3英尺/分钟的气动夹辊组。夹辊材料为:上部=涂有乙烯丙烯二烯单体橡胶的钢,下部=不锈钢。然后将仍然在无孔背衬上的膜加热固化最少4-6小时,以确保完全聚合。固化后,将这些膜小心地从Teflon片移除并如上所述层合到Teflon毡。
实施例1-15:洗涤
为了测定涂层的永久性,随后在水中浸泡1小时之后并接着在2-丙醇中浸泡1小时之后测定带背衬膜上固化的涂布材料的量。永久涂层将经历这些洗涤步骤之后保持涂层材料的初始量,而不完全固化会导致未反应的单体/交联剂或少量的低聚物,这些物质会从有背衬膜上洗去。
过滤
从有背衬膜(该膜要么未涂布并有商品背衬,要么被涂布并可逆地层合到背衬)冲压直径为4.5厘米的圆盘并加载到50毫升的Millipore Amicon Bioseparations超滤室。层合膜在安放期间以及用橡胶O形圈密封时需要格外注意以避免膜从背衬剥离。用异丙醇润湿层合膜,这样似乎减少了该风险。用异丙醇润湿未涂覆膜以确保水流过孔;涂覆膜保持被加入的异丙醇润湿以方便操作。Amicon超滤室的进料管线被两个单独的加压搅拌罐之间的阀门分流,一个搅拌罐用于去离子水,一个搅拌罐用于被测水,以快速简单地在去离子水与被测水进料之间切换。这两个罐一起加压。还布置了加压氮气的旁路管线以通过驱使进料水通过膜来排空超滤室。Amicon 超滤室的出口管线进料到在天平上的捕集容器,以便以重量分析的方式测定通量与时间的函数关系,且这些数据在通过RS232电缆与天平连接的膝上型计算机上使用Mettler Toledo BalanceLink软件收集。
临开始试验前,将两个加压进料容器加压到6 psig,天平去皮重,开始收集数据。打开去离子水进料管线并让去离子水填充Amicon超滤室。当超滤室被填充时,超滤室顶部的放空口关闭,将流引导通过膜。当500g去离子水已经流过膜且已经实现稳定的通量时,关闭去离子水进料管线并打开氮气管线,以通过经膜输送从超滤室全部排空约10ml剩余的去离子水。最后的一点水留在超滤室中以防止膜去湿。随后密封氮气管线并将超滤室放空到大气压。排空天平上的收集容器。随后将进料管线切换到被测水(合成水或油田产出水)。与去离子水一样,让被测水填充Amicon超滤室,然后关闭放空口以引发通过膜的通量。滤液为清澈的,悬浮固体不能通过阻挡层并在膜上累积成饼层。在已经收集400 g被测水滤液之后,将进料管线切换到氮气,持续时长足以在Amicon超滤室中产生一定的顶空。将超滤室放空,将剩余的被测水倾倒出超滤室,用来自挤压瓶的去离子水的轻缓流洗去膜上的饼层,直到饼被去除或直到去离子水流变得无效且没有更多的饼被去除。用去离子水冲洗进料管线以从阀门下游的管线去除被测水。关闭超滤室,再一次排空收集容器,开始第二次相同的500 g的去离子水流。一次循环的“通量恢复率(flux recovery)”定义为100*第二次去离子水通量率/第一次去离子水通量率。
进行三循环试验,包括两次400 g被测水的两次另外的过滤,两次过滤被去除饼和500 g去离子水过滤所分隔。多循环测试的通量恢复率定义为100*最终去离子水通量率/第一次去离子水通量率。
实施例16
喷涂有具有表2所示组成的涂布材料(约19% 3-[羟基(聚亚乙基氧基)-丙基]七甲基三硅氧烷、约10% (十七氟-1,1,2,2-四氢癸基)三甲氧基硅烷和约71% N-(三乙氧基甲硅烷基丙基)-O-聚氧乙烯氨基甲酸酯)的膜用于过滤含油脏水(1000 ppm总悬浮固体;102,500ppm中溶解固体和250 ppm总有机碳)持续三个过滤循环。一个循环由以下组成:过滤400 g含油脏水,洁净水冲洗膜和去离子水通量测定。获得初始去离子水通量测定结果,“恢复率”定义为相对于初始去离子水通量在最后循环之后去离子水通量。使用最优选的涂覆膜时含油脏水三循环的过滤曲线证明回收率为94%,而使用未涂布的膜时证明回收率为62%。采用涂覆膜观察到,在每个循环400 g含油脏水的每个循环平均通量的一致性方面有进一步的提高。
实施例17-20
用烷氧基硅烷SIA0200.0的溶液和由90wt% SIA0200.0和10 wt% SIH5841.5组成的混合物(基于溶液总重量计算总硅烷浓度为0.25wt%)喷涂无背衬膜并在60℃下固化。在固化之后,将膜可逆地层合到PTFE毡背衬。对于实施例19和20,随后将实施例17的层合膜浸没在SBMA甲基丙烯酸酯单体或者SBMA和FMA单体的1:1的混合物(wt/wt)和引发剂VAZO-52在异丙醇/水混合物中的溶液中。将溶液加热至65℃保持2小时以引发聚合反应。在聚合之后,用水洗涤膜层合物1小时,随后用异丙醇洗涤1小时,以去除未反应的单体和游离于溶液的低聚物。结果示于表3。
实施例21-27、对照实施例1-7:用凝结剂和絮凝剂预处理
被测水(TSS = 1000 ppm,TOC = 250 ppm和TDS = 102,500 ppm)在 300-500 rpm下混合,随后加入聚电解质且将该水在300-500 rpm下继续搅拌1分钟,然后在50 rpm下继续搅拌20分钟,然后倾入搅拌的压力罐中用于过滤测试。罐压力保持在6 psi。测试膜为孔径为1.5 µm的ePTFE/PTFE单道膜,未涂布或如实施例16中涂布,用异丙醇将膜预润湿。在测试期间,首先使约500 mL去离子水通过膜以进行通量测定,随后过滤该经化学处理的产出水。流速由滤液重量随时间的增加来测定。之后,通过使用去离子水喷射瓶从膜表面轻缓地去除累积的饼层来恢复。最后,再次使500 mL去离子水通过恢复的膜。膜恢复率百分数用产出水过滤之后与之前去离子水通量的比率来计算。
比较实施例1-7的结果汇总于表4,实施例21-27的结果汇总于表5。在所有测试剂量下,使用未涂覆膜或涂覆膜在平均通量率方面无显著变化。出人意料的是,在所有测试中,与非涂覆膜相比,涂覆膜表现出高得多的恢复率%。在0.5 ppm的阳离子絮凝剂(丙烯酰胺和AETAC共聚物)剂量下膜恢复率%为88%,在1ppm下为57%,与未涂覆膜的恢复率%相比高30%-40%。采用0.1 ppm的阴离子絮凝剂(丙烯酰胺和丙烯酸的共聚物)时,亲水-疏油涂层的膜恢复率从17%提高到96%,采用0.5 ppm的非离子型絮凝剂(聚丙烯酰胺)时从27%提高至72%,采用250ppm的凝结剂(基于丹宁的胺)时从1%提高至37%。上述结果表明,该亲水疏油涂层大大地减少了聚合物分子与膜表面之间的吸引力,使涂布的膜更耐聚电解质凝结剂和絮凝剂。
虽然本文仅仅说明和描述了本发明的某些特征,但是本领域会想到许多修改和变化。因此,应当理解,所附权利要求旨在覆盖所有落在本发明的真正精神内的这些修改和变化。
