LPG Facility Design, Turnkey Supply & Support

Standby Systems provides turnkey engineering, project management and equipment supply for construction of LPG-air facilities used by gas-distribution utilities and industrial / commercial gas consumers of every size. LPG-air systems help reduce the overall cost of natural gas supply while enhancing supply security.

While propane-air peak shaving and standby systems are most common, LPG feedstocks with high butane content are also utilized. By mixing LPG with air, a fuel gas is created with burning characteristics matching available natural gas. Thus, LPG-air mixtures can substitute for some or all flowing gas-energy supply. LPG-air systems are also deployed as base-load systems prior to connection of natural gas in a developing area. Undiluted LPG is of course also widely used around the world. Standby provides a full range of LPG and natural gas products and technical services across the gas-energy spectrum.

Bring more than 300 years of gas-energy experience to your project

Standby's LPG-air experience spans low-pressure standby systems supplying a few million btus per hour through ultra-large, high-pressure, fully-automated, utility peak-shaving plants exceeding 10 billion btuh energy flows. Our engineers, technicians and support personnel bring broad experience and strong industry relationships to every project. A commitment to continuous improvement in technologies, quality, and safety is evident in everything we do.

Security of Supply for Critical Infrastructure

Hospitals, prisons, schools, and military bases are examples of critical facilities where a loss of natural gas supply can have serious consequences. Natural disasters, acts of terrorism, pipeline equipment failures and other events can cause supply disruption with little or no warning. LPG-air systems provide supply security under extreme circumstances, ensuring gas-energy keeps flowing to serve critical needs.

Pre-engineered Systems

Shipped components are clearly labeled and tagged to be assembled per included P&ID.

i-Systems are pre-engineered propane-air and propane-vapor delivery systems:

  • Packaged solutions that are simple to set up
  • Easy to integrate with your existing infrastructure
  • Support any capacity or pressure requirements.

We offer a full range of support services covering extended equipment life cycles.

When the system arrives, components can be dropped in and easily integrated into the existing infrastructure.

Underground 2000 Gallon Propane Tanks and Pump Cover

A secure and attractive enclosure for tank process valves and liquid pumps.

This enclosure houses tank process valves and a liquid pump for an underground tank configuration. Components are secured in an all aluminum enclosure (no paint, no rust) with numerous hinged and lockable equipment access panels.

The assembled enclosure was shipped to the job site as part of our pre-engineered "packaged solutions" approach.
