After more than two years working on this we are launching next week the brand new ASEL-TECH ACOUSTIC PIPELINE LEAK DETECTION & LOCATION TECHNOLOGY, the MARC ONE, requiring less hardware than the SLDS/ILDS, keeping the same performance and priced around at least 30% less! This is a perfect solution for very long pipelines, when the price could be 50% less than the SLDS / ILDS!

All this new LDS requires is an optic fiber cable installed beside the pipeline.
We developed a new concept, eliminating the intermediates FPU's, processing part of the algorithms in the new sensors and having all information transmitted through the optic fiber to the main FPU in the control room. All features of the SLDS/ILDS remain in the new MARC ONE, except the capability to keep until ten spill alarms in the memory in case of communication failure. This characteristic can be compensated by a "communication failure alarm" in the control room and the operator can provide actions to fix the problem. Anyway, if this characteristic is required by the customer it is possible to solve with an additional pair of optic fiber.

The big differentials are LESS FPU'S AND CONSEQUENTILY LESS PANELS, HOUSES, COMMUNICATIONS TOWERS (FOR RADIOS), ENERGY SOURCES, CONSTRUCTIONS, EQUIPMENT EXPOSITION IN THE FIELD, ELECTRICAL CABLES AND CALHAS AND, OF COURSE, INSTALLATIONS COSTS and COMMISSIONING.
For existing pipelines having an optic fiber cable or new pipelines with optic fiber cable this LDS will be unbeatable! NO other LDS can compete in performance and price!

ASEL-TECH is installing the ultimate version of theSLDS-Sonic Leak Detection and Location System for the biggest petrochemical complex in South America; BRASKEM.
This SLDS is being installed into two NAPHATA pipelines, 30 miles length, from the port to the Petrochemical Complex.
The system will be in operation by July 2011.

Some countries have started to institute laws mandating pipeline operators to install Pipeline Leak Detection Systems as a viable safeguard against environmental damage from pipeline failures, Brazil being the most recent. It is the general feeling that other countries will follow suit in the near future.

For the past nearly two decades, “Mass Balance” (MB) has been the leak detection technology of choice. The truth is; Mass Balance has a very limited history of success in the area of leak detection. This is not to say it does not work, it just has some very (documented) limiting operational constraints when deployed as a stand-alone leak detection system.

• MB systems are not viable for multi-phase product lines and gas lines.
• MB systems are not feasible for pipelines with varying flow and pressure or pipelines with slack-flow or blocked flow.
• MB typically will not detect leaks below 10% of the pipeline flow rate
• MB will not indicate leak location
• MB takes from many hours to several days to detect and alarm a leak

Some positive aspects of MB are its ability to detect very slow developing leaks and or pre-existing leaks. MB can also quantify a leak when detected.

Asel-Tech has substantial experience in the field of Pipeline Leak Detection. We have developed a very new and innovative system which combines Mass Balance with our Sonic Leak Detection System - ILDS, or Integrated Leak Detection System. ILDS offers pipeline operators a redundant system:

• ILDS will detect leaks with flow less than 2% of pipeline flow rate
• ILDS will alarm detection of a leak in a matter of seconds from occurrence
• ILDS is effective with liquid, multi-phase or gas products
• ILDS is effective in pipelines with varying flow, pressure & even slack-flow
• ILDS Will indicate leak location
• ILDS will quantify the leak

The Asel-Tech ILDS can be very competitively installed on your pipeline.

Asel-Tech's Sonic Leak Detection and Location System is the most reliable and sensitive leak detection system available on the market today. Our system is capable of reliably detecting incidents in a matter of seconds. Some advantages of our acoustic leak detection system can be summarized as follows:

• Very fast - detects leaks at the speed of sound, and is not dependent on the size of the leak.
• Detection is not dependent on flow parameters
• The loss of communication network does not affect the sensors ability to detect leaks. Any communication failure is immediately posted, and the field processing units have internal buffers which store any recordable event for audit in case of communication failure along with time stamps.
• Does not require third person instrumentation
• The system works with liquids, gases and multiphase products
• Easily  interfaced with SCADA systems
• Can be configured to automatically close valves in case of a leak,
• Calibration is not required
• There is no proprietary software
• There are no dead zones - 100% of the pipeline is monitored.
• Specially developed algorithms and methods for leak sensors ,
• User friendly interface
• GPS time stamping
• Acquisition of long-term data with the use of Data Loggers,
• Reprogramming of leak masks,
• Field test leak simulation without using rupture disks.

AVOID DISASTERS - ASEL-TECH's SONIC LEAK DETECTION SYSTEM (SLDS) FOR TERMINALS

We are proud to announce the creation of the ASEL-TECH INC., with headquarter in HOUSTON-TX.

The target is to enter in the USA market with our advanced ILDS-Integrated Leak Detection System, considered the most advanced pipeline leak detection, location and quantification system! We are selling this technology to several countries and targeting to apply the ILDS to the thousand kilometers of pipelines in the US!

Asel-Tech acoustic and integrated technologies are becoming recognized as the most effective for pipeline leak detection and location, granting to users confidence and safety, protecting life and the environment.
