At Blair Engineering, we understand that turboexpanders are critical to your plant’s operation and provide solutions with reliability and performance in mind. We offer both fully-skidded new-unit packages custom-built for your application, as well as aftermarket parts, redesign, service and support for all turboexpander brands. Our standard delivery schedules are very competitive, and if the need should arise we also offer expedited deliveries that are significantly reduced compared to what other manufacturers are able to provide. We are known for our customer-centered approach and offer world-class service and support to keep your turboexpander operating 24/7.
New Skidded Packages
Our standardized oil bearing skidded package designs offer competitive pricing and delivery for cryogenic gas plants ranging from 25 MMSCFD to 300 MMSCFD. With custom designed aerodynamics for every job, we routinely exceed customers process performance requirements as well as the low operating noise level that is expected from modern turbomachinery design. Magnetic bearing machines are also available if desired.
System Features
Our API 610/614 support system design utilizes magnetic coupled pumps as standard, eliminating the operational issues associated with other high pressure mechanical sealed pumps. As standard, system piping is stainless steel for cleanliness, which also eliminates the need to perform a complete flush of the lube system during commissioning. IEEE-841 motors are used for the lube oil fan and pump drives as standard. ASME rated vertical cooler, simplex seal gas filter housing, duplex lube oil filter housing, and lube oil reservoir are also standard.
Control System
Blair Engineering’s standard turbo-expander package incorporates an on skid control system using an Allen Bradley PanelView 1500 plus 7 HMI with a CompactLogix PLC. Industry standard Rosemount pressure transmitters are used and are indicating to eliminate the need for additional gauges. While other area classifications are available, Blair Engineering’s standard package meets or exceeds Class 1 Div 2 Group C, D specification.
Machine Features
Designed per API-617 and equipped with a variable inlet guide vane mechanism, Blair Engineering’s turbo-expander frames operate efficiently across a wide range of conditions. A fisher actuator with an electronic HART positioner is supplied for precise inlet guide vane control and ease of field calibration. As per standard, a thrust balance valve is included on all turbo-expander designs. Impellers are milled in house from billet material, and are custom designed per application. Our typical compressor aerodynamic designs are high back sweep type, which gives the widest operating range and highest performance. Each impeller design is overspeed tested and precision balanced for years of trouble free operation.
Bearings are manufactured in house and are combination radial and thrust bearing with embedded dual element RTD for accurate bearing temperature measurement. Blair Engineering turboexpanders use a stiff shaft design, without rotor criticals, to allow for operation at any speed without mechanical risk to the rotor parts.
Whether you are looking to upgrade an existing facility or are building a new facility, Blair Engineering can support your new equipment needs. For more information, or to request a quote, please contact Blair Engineering at (805) 457-8800 or by email at Contact@Blair-Engineering.com.
Aftermarket Design, Parts and Services
Our experience spans all brands, including Texas Turbines Inc., Rotoflow, Mafi-Trench, LA Turbine, Gas Power Systems, Cryostar, Airco, Atlas Copco, GE, and more. At Blair Engineering, we can reverse engineer and supply turboexpander parts from any supplier and provide upgrades to bring your expander design into the 21st century. Blair Engineering provides a level of engineering support that you may not otherwise get from the original equipment manufacturer (OEM).
Performance Upgrades
When conditions vary beyond the original specification, a redesign is necessary to restore or enhance machine performance. We provide high-performance, cost-effective turboexpander upgrades with very competitive delivery schedules. With our wide ranging experience, we can increase the rating capacity of most machines. We also have performed a significant number of low flow redesigns which allows for the installation of a larger plant than required to allow a field’s production to grow into the facility, or in the case of an older plant to match declining field production and maintain plant recoveries.
Ready-to-Run Spares
Keeping a spare rotating assembly (SRA, or MCS) in ready-to-run condition is critical to minimize operational downtime should an issue arise with your operating turboexpander. At Blair Engineering, we can cost-effectively rebuild your machine to as-new condition or provide loose spares, with competitive price and delivery.
Environmental Upgrades
With today’s environmental standards, LDAR leaks are an increasingly common problem with older plants. Blair Engineering offers retrofit parts to upgrade your leaking guide vane actuator seals to modern types with back-up seals. Some components are kept in stock to minimize the delivery time to provide these seal retrofits.
