"Leak Detection Guarantees Pipeline Safety as Your Business Grows"

 

Introduction

Risk management is crucial when expanding your business. For example, when adding or expanding long range pipelines for LNG or liquid ammonia, ethylene, sulfur, compressed gas, or other hazardous substances, it is essential to form a risk prevention plan not only for inside the facilities but also for the surrounding areas. Failing to assemble the requirements for guaranteeing safety makes it impossible to add or expand plants, and potentially rules the company out from major business opportunities. The DTSX distributed temperature optical fiber sensor is a pipeline leak detection solution whose core value lies not only in avoiding risk during operations, but also in guaranteeing safety when adding or expanding plants. In certain projects, adding the safety instrumented systems that are key to those same applications wins approval from independent government agencies to install pipelines for liquid ammonia near residential areas. Pipelines that connect factories to shipping yards approximately 5 km away help customers expand their export businesses. And pipeline leak detection applications play a major role in developing new business.

What is the DTSX Distributed Temperature Optical Fiber Sensor?

The DTSX is a module that can be used as an optical fiber sensor to enable temperature monitoring over wide areas.

Customer Benefits

  • Identifies Even Minor Leaks in 1-meter Units, and Triggers Shutdowns
  • Avoid Risk while Keeping Running Costs Down

Solution and Benefits

Monitors the Entire are 24 Hours a Day, 365 Days a Year

Optical fiber sensors along the surface of the pipeline notify you of leaks by detecting temperature changes. One DTSX and its software application cover up to 50 km of pipeline. Since it monitors 24 hours a day, 365 days a year with no blind spots, it is an ideal component of a risk prevention system.

Identifies Even Minor Leaks in 1-meter Units, and Triggers Shutdowns

Slight leaks in pipelines can grow to large disasters. However, detection through pressure drops, mass balance, modeling, and other techniques is difficult, and it is tricky to pinpoint a location. The DTSX leak detection application captures changes in the surface temperature of the pipeline in 1-meter units at least every 10 seconds. That means it can immediately detect leaks of any size, and even makes it easy to find the location of a leak. And as part of a total Yokogawa solution, you can install a safety system that links up with the leak detection function to shut down the pipeline.

Avoid Risk while Keeping Running Costs Down

Pipeline sensor installations only require optical fiber, so no control of power system lines are needed. Also, optical fiber sensors require almost no maintenance. You can decrease risk while minimizing running costs.

DTSX200 Distributed Temperature Sensor

The DTSX200 is a standard version that is ideal for temperature measurement, for medium-sized areas, and for areas where the distance of fiber optic sensor cables is short. It has excellent environmental resistance because it consumes less power and is less dependent on the temperature measurement environment.

DTSX3000 Distributed Temperature Sensor

The DTSX3000 is a distributed temperature sensor developed in response to the demand that “one unit be used to monitor temperature distribution a longer distance and a wider area”. A flagship model that meets the expectations for long-distance temperature measurement and high temperature resolution.

Distributed Temperature Sensor

We adopt technology that the optical fiber cable itself functions as a temperature sensor.
Since it measures temperature distribution over a long distance and a wide range, partial temperature change is not overlooked. Therefore, it is effective not only in the plant but also in fields requiring temperature monitoring.
