White Papers

The modern combustion gas turbine is one of the most reliable machines in use and a workhorse of the electric power generation industry. It can be on-site and running in a relatively short period, providing quick additional power capability when needed.

At times, it can seem to be a daunting task – reduce operating costs and increase efficiencies to reduce carbon footprint, all while maintaining peak performance. But new technologies exist that can help optimize efficiency and sustainability. Ship owners who apply this technology to their fleet can see significant operating savings, enhanced uptime, reduced carbon footprint and an increase in profitability.

The impetus for the development of the Babbitt lined steel rotor housing has its roots with the U.S. Navy, back in the late 1960s/early 1970s. It was at this time that the Navy undertook a major fuel conversion, from Navy Special Fuel Oil (NSFO) - an approximate blend of 60 percent Bunker C/40 percent distillate fuel - to a 100 percent distillate fuel.

New technology – smart technology – is available that enables vessel and fleet operators to achieve substantial energy savings by running pumps more efficiently via a sophisticated control system. Such a system can be applied to both newbuild and retrofit situations.

For more than 70 years, CIRCOR has been working with the commercial marine industry to keep pace with changing compliance and regulation demands, as well as helping the industry meet evolving environmental issues.  This white paper highlights one of our latest efforts:  the search for pumping equipment that can meet the demands of low-viscosity, low-sulfur fuels.

CIRCOR factors efficiency gains into their solutions that look beyond initial investment costs and ongoing ownership costs. They use the concept of total savings of ownership (TSO) to create value across an organization. Ship managers no longer need to think of “equipment suppliers,” rather they are choosing a pump technology partner – an organization that provides the people that will integrate their solutions in the most timely and efficient manner.

Two screw pumps are one of the most versatile and functional pump types, yet they remain largely unknown in the chemical process industry. This white paper highlights best practices and offers design tips for engineers evaluating their pump system and reactor vessels.

The term 'screw pump' is often used generically.  However, this generalization can be a pitfall as it fails to recognize the different products or 'screw' configurations, as well as the uses, advantages and design considerations for each.  The design differences of each screw configuration and pump type make each suitable for different applications and handling fluids with varying characteristics.

For years, rotary pumps have been the standard in delivering high-efficiency, low-maintenance fluid handling solutions for critical applications. However, there's often been a perception that screw pumps are expensive, which prevents many crude oil transport companies from taking full advantage of the built-in benefits for energy savings and reduced environmental impact they offer. The fact is positive displacement screw pumps deliver tremendous cost advantages.
