new equipment L.A. Turbine designs and manufactures Turboexpanders for use in Hydrocarbon Gas Processing, Air Separation, Refrigeration and Energy Recovery Industries.

Expander-Compressor: High-speed rotating machines used in cryogenic applications including natural gas, petrochemical, and air separation industries. The power that the expander removes from the gas expansion is entirely transferred to the compressor’s impeller and the expander produces the process refrigeration necessary for cryogenic gas processing while recovering that power for use elsewhere in the process.

Expander-Generator: Converts the energy from the gas expansion into electric

power. These machines come in three configurations. In the first, the high speed expander shaft is coupled to a gearbox, which is then coupled to the generator. In the second, the expander wheel is directly mounted on the high-speed gearbox pinion, eliminating the high-speed coupling. In the third, the expander wheel is directly mounted on the shaft of a high-speed generator, eliminating the gearbox entirely.

Expander-Brake: Energy recovered from the gas expansion is absorbed by a brake wheel rotating in an oil stream or air stream.

geothermal power solutions L.A Turbine is the world’s most experienced manufacturing company of Turboexpander equipment to generate power from Geothermal renewable energy. Our Team built the equipment for Mammoth Pacific and Steamboat Nevada. The equipment is actually owned by Ormat and uses the binary process.

The same Team built the Turboexpander Equipment using the direct steam process for CalEnergy in Salton Sea. This is the biggest Turboexpander ever built for this application.

Since 2003, those Turboexpanders have been overhauled and redesigned by the same Team, now employed at L.A. Turbine. The Team, has over 300 years of cumulated experience with the Geothermal power generation equipment using the Turboexpander technology

redesign and reverse engineering Getting the most from your Turboexpander is critical. High efficiency is essential to success in today's process plant. If you experience low efficiency, a change in operating conditions, or process contamination, it may be time to look at a redesign.

Performance: If your unit has been in service for a while, your gas supply may be quite different than the original design conditions. Advances in engineering and design mean that additional gains in efficiency may be readily available.

Free Evaluation: L.A. Turbine will perform a free evaluation of your current Turboexpander operation at no charge. If mechanical or performance improvements can be made, we'll show you how to get there. To obtain your free analysis, call 1-661-294-8290 or email sales@laturbine.com.

Reliability: L.A. Turbine has a proven track record of improving the mechanical reliability of existing units, regardless of their original manufacturer.

BEFORE AFTER

spare parts L.A. Turbine can support you in determining the best balance between spares inventory and unnecessary inventory.

Spares Recommendations: Normally a Turboexpander may operate for many years without servicing. However, certain spare parts should always be kept on hand in case of emergency. Recommended spares fall into several categories:

Gasket sets, o-ring kits, and Teflon seals should always be •kept available.Disposable filter elements for lube oil and seal gas filters.•Repair kits for critical skid-mounted valves, actuators, •regulators, and pumps.

A spare MCS (Mechanical Center Section) is also a critical part of a complete spares inventory. The spare MCS includes all of the rotating parts of the expander. If the installed unit is damaged, the MCS can be installed in a few days rather than weeks. This dramatically reduces down time and lost production.

control systems Today's vibration analysts and mechanical engineers desire a flexible data acquisition, monitoring, and control platform to more precisely diagnose and predict machinery malfunction. With a flexible data acquisition and analysis system, you gain the ability to easily expand input channel count and analysis functionality, without expensive upgrades. Similarly, data acquisition can be applied to post-manufacturing testing and real-time monitoring in the field.
