John Crane Awarded Patent for Gas Seal Monitoring Technology
Reflects continued investment in new technology and potential to transform $8
billion gas seal industry
CHICAGO -- March 10, 2014
The U.S. and European patent offices have awarded John Crane a patent for a
breakthrough technology that will monitor the condition of a gas seal to
improve product performance, extend average product lifespan and aid emission
reduction in operations across the energy sector. The patented technology will
be the next step-change leading to improved gas seal reliability, equipment
uptime and lower operating costs for customers.
The patent outlines several configurations of an advanced gas seal condition
monitoring system that will provide comprehensive and continuous real time
monitoring of the status of a compressor, control panel and gas seal to
improve gas seal performance. In-house prototype testing is scheduled through
this summer, and extensive customer field tests will follow. Proprietary
information was not released.
Joseph Haas, Chief Technology Officer of John Crane said: “This new technology
is just one example of how John Crane is committed to R&D investment in
engineered solutions that address customers’ growing processing demands while
supporting environmental impact and improved energy efficiency. Because a gas
seal is critical to our customers’ operations, monitoring its performance will
further reduce chances of downtime that could cost them close to one million
dollars a day.”
John Crane is holding its next employee innovation recognition event on the
12th of March at its Slough manufacturing site near London. Twelve inventors
will be honored for a variety of recent patent awards.
In 1968, the first gas seal patent reinforced the company’s reputation as a
world leader in sealing technology. Innovation continued when the company
introduced a non-contacting, gas-lubricated seal in the 1980s, and in the
1990s, designed a next-generation gas seal for pumps that handle
environmentally sensitive liquids. Applying this latest technology to a
standard American National Standards Institute (ANSI) or American Petroleum
Institute (API) pump will assist customers to meet or exceed the U.S.
Environmental Protection Agency's (EPA) stringent regulations for hazardous
emissions. Today, the latest John Crane gas seal technology is used by
thousands of customers across the energy services sector, including mid- and
downstream oil and gas segments.
John Crane is close to marking a century of engineering solutions innovation
and leadership with the company founded in 1917 and built from multiple
inventions by Mr. John Crane. The company continues to build its legacy of
strong proprietary product technology, with more than 230 active patents and
patent applications. In total, the company holds more than 1100 patents.
