Dow公司的ROMAX系列净水剂专为将油从产出水和水包油乳化液中分离而设计。它们有助于确保水中油含量足够低，从而使水可以返回到系统中重新利用。该系列产品可以将残余的水包油含量从1000 ppm降至20 ppm以下，而且不需要像常规产品那样，在加药前通常需要从烃中除去净水剂的转化过程。
Dow公司提供净水剂的解决方案，以满足各种最终配方的需求。为了定制设计适合您自己的净水剂，Dow以ROMAX™7000系列为基础，还提供基于这些公认的阴离子基质的完全配方产品。ROMAX™ 6000系列阴离子、阳离子和非离子型净水剂完全按照配方制造，到达现场即可立即使用。而对于更加寒冷的气候，我们的ROMAX™ 9000系列净水剂是抗低温稳定型配方，可在-40ºC的低温下正常使用。
采出水回注中即使将极少量石油重新注入地层环境中也可能造成污油快速累积，影响最终效益，又向环境监管机构亮出红灯。从全球范围来看，已经建立了排放水中含油标准，以确保排出水中含油量处于安全水平，便于进行处理或再利用。 规格因国而异，范围在15-50 ppm之间。
当目标是再利用而不是排放时，ROMAX™产品有助于确保油含量足够低，从而可以使水安全再利用，并集成到系统中。在使用ROMAX产品1-20 ppm加量下，可以将残余水包油含量从1000 ppm降至20 ppm以下。
ROMAX™ Water Clarifiers
Dow’s ROMAX series of water clarifiers are designed to separate oil from produced water and reverse emulsions. They help ensure that oil levels are low enough such that the water can be reused and integrated into a system, reducing residual oil-in-water from more than 1,000 ppm to below 20 ppm. The clarifiers do not require the inversion that conventional products often require to remove the water clarifier from the hydrocarbon prior to dosing.
Dow provides two series of Water Clarifiers, The ROMAX 6000 Series; fully formulated anionic, cationic and nonionic water clarifiers that are ready to use as soon as they arrive at the field and the ROMAX 9000 Series; freeze-stabilized formulations for use at temperatures as low as -40 ºF (-40 ºC).

Raising the Bar in Oil/Water Separation
Tightening environmental regulations and the limited supply of fresh water are driving the oil and gas industry to seek new solutions for reducing oil in water prior to discharge and to employ reuse schemes in water-intensive activities such as boilers and direct injection for enhanced oil recovery processes. ROMAX™ Water Clarifiers from Dow provide a valuable solution for separating oil from produced water and reverse (oil-in-water) emulsions, helping to protect both the environment and production equipment.
Building on the Basics
Dow offers water clarifier solutions to meet a wide variety of final formulation needs. To custom-design your own clarifier formulation, we offer the ROMAX™ 7000 series of bases. We also offer fully formulated products based on these well-established anionic bases. The ROMAX 6000 series of anionic, cationic and nonionic water clarifiers are fully formulated and ready to use as soon as they arrive at the field. And for colder climates, our ROMAX 9000 serie of water clarifiers are freeze-stabilized formulations for use at temperatures as low as -40 ºF (-40 ºC).
Ensure Compliance, Save Money
Re-injecting even small quantities of oil back into the environment through produced water can quickly add up, negatively impacting your bottom line and raising a red flag to environmental regulators. Globally, oil and grease specs on discharged water have been established to ensure the amount of oil in water is at a safe level for disposal or reuse. Specifications vary from country to country in a range of more than 15-50 ppm.
When the goal is reuse rather than discharge, ROMAX™ products help ensure that oil levels are low enough such that the water can be confidently reused and integrated back into the system. With dosage rates of 1-20 ppm of ROMAX products, it is possible to reduce residual oil-in-water from more than 1,000 ppm to below 20 ppm.
Aqueous-Based Chemistry Enables Field-Ready Formulations
Dow’s application expertise has allowed us to develop fully formulated ROMAX™ Water Clarifiers. Conventional products use a hydrocarbon-based solvent that requires a laborious inversion process to remove the water clarifier from the hydrocarbon prior to dosing. But our aqueous-based products require no such inversion, meaning that they are ready to use upon arrival and can be dosed immediately.
