Membrane unit for flow-back water treatment offshore

Offentlig prosjektsammendrag

Despite the fact that several new purification technologies have been introduced to the O&G industry - including hydrocyclones, compact flotation, hydrocyclones in combination with compact flotation, hydrocyclones combined with CTour, Macro Porous Polymer Extraction (MPPE), and hydrocyclones combined with Nutshell filter - the primary water treatment techniques have hardly changed in the last 30 years. The above methods are all space consuming, maintenance-intensive and / or very costly in purchasing. There are also significant challenges associated with adapting water treatment technologies to field-specific conditions, as well as meeting regulatory minimum requirements. The above leads to customized, costly and low scalable solutions. Sales of new technology must therefore be based on arguments that deal with both the environment awareness and the economy. The main objective of the project is to develop and demonstrate a compact and efficient prototype unit based on flat sheet ceramic membrane for the treatment of offspec produced water for offshore O&G branch. Norwegian Recycling Services's unique approach to treating produced water is based on a combination of pre-treatment, ceramic flat-sheet membranes and integration of an unique technical solution for minimization of membrane erosion. The developed unit will be able to concentrate and minimize the final waste and be sufficiently robust and flexible to deal with a wide range of water quality and operational conditions. Norwegian Recycling Services AS aims to create a robust and scalable solution that can function as the ultimate solution for the offshore treatment of produced water. Close dialogues with ConocoPhillips have led to the proposal for one innovation contract - based on both environmental arguments, cost savings and increased revenue potential.
