2. Heat Exchanger Leakage Detection

Present Scenerio

Present Technique-Shut down and visual inspection

  • Limitations in Existing Technique:-

  1. Time consuming

  2. Very costly which involves huge loss due to process shutdown.

Applications

To identify the leaking heat exchanger from the heat exchanger series

Advantages

  1. Online Technology, No Requirement of Process Shutdown

  2. Huge Savings on Shutdown Costs

  3. Faster method of Detection and Analysis

  4. Preparation for Detection Process can be Undertaken without Disturbing Plant Operations

  5. Cost Effective

3. Sediment Transport Study​

Present Scenario

Present Technique-Rough understanding based on scaled down mathematical models of the ports

  • Limitations in Existing Technique:-

  1. No accuracy

  2. Time consuming

  3. Very costly

Applications

To propose suitable site for disposal of dredged sediments from navigation channel of the port
Ports stand to advantage as sediments deposited at selected locations will not spill back into to the navigation channel
Suitable location for sediment disposal can be accurately selected as close as feasible which would result in huge saving of dredging costs

Advantages

  • High Detection Sensitivity

  • Unambiguous

  • Cost Effective

4. Pipe Scanning

Present Scenario

  • No technology available to correctly assess the exact location and nature of blockage

  • The entire pipeline requires to be closed for operation which results in heavy revenue losses

  • Vey time consuming

  • Present method require heavy manpower and transportation for removal and shifting of liquid in affected pipeline at the time of repairs

Applications

Investigate presence of blockage, its specific location and its extent both in underground and over-ground pipelines.

Advantages

  • High Detection Sensitivity

  • Unambiguous

  • Pinpoint Detection of Problem Area

  • Faster Method of Detection and Analysis

  • Cost Effective

  • Protects Environment

5. Leakage Detection From Reservoirs

Present Scenario

Present Technique-Visual inspection to assess leakage

Grouting carried out not in conformity with leakage location.

  • Limitations in Existing Technique:-

  1. No accuracy

  2. Time consuming

  3. Unnecessary heavy expenditure without confirming exact location of the leakage source

  4. Very costly

Applications

  • To pinpoint location of leakage in dams

  • On confirmation of the exact location, the same can be arrested by specific grouting (services provided by BVG) which will result in considerable cost saving and loss of water.

  • ​

Advantages

  • Accurate Pinpointing of Leakage

  • Results in saving of Water which would otherwise have wasted due to non detection of leakage source in time.

  • Faster method of Detection and Analysis

  • Cost Effective
