Beneficial reuse of flare gas recovers freshwater

摘要

As the volume of highly saline produced water continues to rise, the industry will need to continue to innovate in order to safely, sustainably, and economically manage this towering volume of wastewater. The Heartland Concentrator demonstrated that direct-contact evaporation can be an effective part of an overall water management plan. By successfully operating in both a ZLD mode for solid waste disposal and in brine mode for a combination of beneficial reuse and deep-well volume reduction disposal, the Heartland Concentrator successfully demonstrated its operational flexibility and effectiveness across a wide range of treatment specifications. And by utilizing wellhead gas as the source of thermal energy, Heartland beneficially reused a previously wasted energy source. Along with produced water reuse and UIC well disposal, onsite evaporation should be considered as an important tool in managing increasing produced water challenges.
