Oil & Gas Industry

With almost 25 years of experience, Synder Filtration has proven to be one of the top suppliers of membrane technology across a wide range of industries. As a manufacturer of both custom membranes and systems, we strive to provide quality products and reliable service for our customers around the world. Our nanofiltration line of elements has recently expanded to show effectiveness for applications such as desalination and sulfate removal. We strive to fully understand the needs of our customers, in order to produce membranes and systems suitable for their separation needs.


Challenge

In 2014, Synder introduced NFS, a specially formulated nanofiltration membrane that delivers superior sulfate rejection in fast growing applications such as waterflood injection processes in the oil and gas industry.

In seawater, sulfate ions interact with barium and strontium, resulting in scale formation that significantly reduces process output and efficiency. In addition, high sulfate concentrations can lead to the formation of hydrogen sulfide, which results in oil well souring.

Nanofiltration is a proven separation technology that helps prevent this type of scaling and souring in seawater environments, therefore improving the efficiency of waterflooding processes and enhancing oil recovery.

Solution

To meet the growing demand for sulfate removal methods in the oil and gas industry, Synder developed the NFS membrane, a thin-film composite nanofiltration membrane with a molecular weight cut-off of 100-250 Daltons. This membrane consistently produces greater flux vs. leading competitors, increasing efficiency and potentially reducing NF system footprint on offshore oil platforms. The average sulfate rejection of NFS is greater than 99.5%, with an observed 25-30% increase in flux compared to the leading competitor, when tested in a feed stream of synthetic sea salt at typical operating conditions.

The membrane also exhibits a high-degree of mechanical strength, as well as excellent pH temperature, and fouling resistance, making it highly suitable for enhanced oil recovery (EOR) techniques and sulfate removal application throughout the oil and gas industry.

Case Study

The objective of this study was to examine the performance of Synder’s NFS sulfate removal membrane against that of a leading competitor with an incoming feed stream representative of that found in the field. ASTM D1141-52 is a well-known, standard practice for the preparation of substitute ocean water and was therefore used in this study to simulate seawater, a common feed for waterflood injection processes.
