Speaking at Gastech 2018, Nancy Ballout, Vice President Process Engineering and Operations, AG&P, said that application of the new technologies to regasification modules would help provide commercially compelling solutions and therefore options for customers to access gas.

Water-bath type vaporization (WBV) technology

AG&P has developed a standardized WBV technology that utilizes fire tubes to transfer heat to a bath of water by convective and conductive heat transfer. The combustion gas never directly contacts the water. To minimize emissions and improve efficiency, the design can also include low NOx burner technology and a waste heat recovery economizer providing high efficiency without the complexity associated with other systems.

The benefits of this unique design are:

  • Flexible: suitable for offshore and onshore applications where space is limited
  • Adaptable: ideal for cold climate and environmentally regulated sites, including sites where an open loop system utilizing seawater is not feasible
  • Efficient: comparable to submerged combustion vaporizers (SCVs) normally used onshore in cold climates but designed to be used in offshore/floating applications
  • Value-adding: ensures a highly competitive footprint that maximizes space and assets

Fan ambient air vaporization (FAV) technology

AG&P has also developed an advanced and highly cost-efficient FAV technology for sub-tropical and tropical locations with ambient air temperatures greater than 15°C with adequate available space. AG&P’s FAV technology offers a significant improvement as it simplifies the design of the regasification train, its operations and maintenance.

The unique benefits are:

  • Reduced size: AG&P’s FAV regasification trains have been carefully designed to minimize size and complexity, allowing for a faster build and easier installation
  • Flexible: the technology enables the module to be split into two or stick-built and installed onsite, making it suitable for sites that cannot be accessed with a single, pre-fabricated module
  • Optimized operations: a suite of integrated features that maximize space, improve flow and increase utilization to improve overall operational efficiencies

“These two new technologies complement AG&P’s water-glycol shell and tube (STV) standard technology for regasification modules, which was introduced in 2017. All three technologies use the right combination of onshore and offshore assets, that can be scaled to meet current demand with the flexibility to expand to match future growth and investment,” said Ms. Ballout.

“Our technologies allow us to configure hybrid terminals which is extremely cost-effective and allows for installation in locations that are currently constrained or inaccessible. Modularization ensures faster fabrication and easier transportation, so facilities are up and running sooner.”

The three technologies will be deployed at AG&P’s LNG import terminal at Karaikal Port in India and at two facilities currently under development in Latin America.
