History

1928
The Contactor™ reactor is invented by C.W. Stratford, founder of the Stratford Engineering Corp. (SEC) in Kansas City, Missouri, USA. His revolutionary equipment manufactures lubricating greases at the lowest operating cost in the industry.
1929
The first Contactor™ reactor is installed at a Kansas City grease plant.
1930’s
SEC supplied processing equipment for lubricating grease and treating crude oil distillates and lube oils. Started development of Alkylation technology and designed first experimental Alkylation Contactor™ reactors.
1940’s
Full and rapid commercialization of both Sulfuric acid and HF Alkylation tehchnology to support aviation fuel demands of WWII.
1950’s
Korean War spurs further evolution of Alkylation technology and market growth.  NEW research laboratory for Stratford Engineering opens in Kansas City. It proves to be a catalyst for future growth and home base for development of hundreds of patents.
1960’s
Aviation fuel demand diminished while use of alkylate as a gasoline blending component grew. Effluent refrigeration process is developed from an innovation in Alkylation technology that provides necessary refrigeration from the product effluent stream.
1970’s
Ward Graham becomes President and establishes a new vision and began to rebuild and expand with the new name of Stratford/Graham Engineering. Unfortunately, Mr. and Mrs. Graham passed away less than two years later.
1981
Taking on her father's dream, Diane Graham becomes Chairman/President of the company and heads up sponsorship of the first Alkylation seminar with more than 100 international customers. In 1986 she becomes Owner and CEO.
1984
Stratford/Graham Engineering becomes STRATCO®, Inc. The newly-named company is committed to strengthening its global leadership in reaction technology.
1980's
Diane becomes the sole owner of STRATCO®, Inc. STRATCO® qualifies as a woman-owned company. STRATCO® added process and mechanical improvements to existing technologies and equipment designs. Research and Development efforts were increased to include mixing products for companies in numerous industries: foods, pharmaceutical ointments, nutritional drinks, asphalt, soaps and lotions. In Alkylation, a trend toward the sulfuric acid catalyzed process occurred in this era, with STRATCO's® effluent refrigerated process as the premier option. With the global demand for safe, environmentally friendly process technologies, STRATCO® licensed 85% of all Alkylation units installed worldwide.
1990
STRATCO® leads the world in Alkylation technology and holds the largest market share in Alkylation capacity installed. STRATCO® begins research and development in polymer modified asphalts and in the manufacturing of biodiesel.
1992
Diane Graham becomes the first female President of NLGI in the organization’s 60-year history.
1997
World headquarters opens in Scottsdale, AZ.
1998
Segregation olefin patent is developed which furthers Alkylation technology. This innovative development allows for a significant improvement in product quality and operating costs by segregating feedstock.
2001
London office opens to better serve European and global customers.
2003
Akylation division was sold.
2004
STRATCO Global Company, Ecopath, is created as a member of the STRATCO® Global family of companies to provide solutions for the modified asphalt industry. Ecopath asphalt rubber blending plants are placed in service, paving the way for future growth and prosperity. Ecopath hosts AR Technology seminar in Colorado.
2005
Ecopath asphalt rubber blending equipment is now in place in North America, Europe and Russia, earning high praise for quality and efficiency as well as its environmental friendliness.
2006
STRATCO® designed and built state-of-the-art grease manufacturing plant in Alabama representing the first of its kind built outside of Japan. STRATCO® enters the roofing industry with new equipment applications in asphalt roofing shingle manufacturing.
2007
Ecopath Contracting wins the prestigious Department of Environmental Protection (DEP) Annual Recycling Award.
2008
Ecopath expands research and development in all types of modified asphalt technologies.
2009-2012
STRATCO® and ECOPATH Holdings continue to expand globally. Stratford Engineering, LLC was formed and offers equipment and services to the Alkylation Industry, including new mechanical seals.
