Rivertrace launches wash water monitor for scrubbers


Smart ESM monitor measures PAH, turbidity, temperature and pH on open-loop, closed-loop and hybrid scrubber systems.

Rivertrace, a company with over 30 years' experience of oil-in-water monitoring, has launched its Smart ESM monitor at the Sulphur Cap 2020 Conference, Awards and Exhibition, being held in Amsterdam this week.

With the pending sulphur cap regulations in sight, one solution for shipowners to ensure compliance will be to install an exhaust gas cleaning system (EGCS), also known as scrubbers. Wet scrubber systems use wash water to remove the pollutants from the exhaust gas, and the wash water being discharged must be monitored at all times to ensure it is within the limits set by the regulating body.

The Smart ESM developed by Rivertrace is a wash water monitor designed for both the inlet and outlet of a wet exhaust gas cleaning system, measuring and recording PAH, turbidity, temperature and pH on open-loop, closed-loop and hybrid scrubber systems.

Rivertrace says the Smart ESM is fully compliant with IMO MEPC 259(68) guidelines for exhaust gas cleaning systems, whilst also provides reliable information to ensure compliance with worldwide sulphur oxide (SOx) limits.

The Smart ESM has a large 10-inch touch screen display. Data is relayed to the ship's main control system via an ethernet connection and 4-20 mA analogue outputs and has the ability to interact with other systems using Modbus protocols. The monitor provides onscreen graphs showing either live data or historic hourly, daily or weekly figures. Data can be emailed automatically anywhere in the world for accurate record keeping. The monitor also provides automatic cleaning of the optical path to ensure continual accuracy.

The Smart ESM has been developed to support all scrubber systems and includes a broad selection of inbuilt analogue and digital outputs.

Mike Coomber, Managing Director of Rivertrace said: "We are excited to launch the Smart ESM, which is the latest in our innovative range of monitoring products. The 2020 global sulphur limit is an important milestone for our industry and we are delighted that we are able to offer such a positive contribution to ensuring the ongoing compliance to new regulations which will reduce harmful impacts of shipping on the environment. We are working in partnership with a number of OEMs ensuring we supply a complimentary and complete solution."
