Los Angeles (March 3, 2014) - Ronald F. Ambrosini, an engineer with over 40 years’ experience with major process technology projects, has joined OnQuest as Senior Project Manager in its San Dimas office, announced firm president and CEO Randy Kessler.

Ambrosini is an accomplished project manager with an extensive background in process design and development for hydrocarbon refining facilities, natural gas treatment plants, and refineries for petrochemicals and minerals processing.

In his new role, Ambrosini will primarily focus on managing OnQuest's growing number of projects providing turnkey engineering, procurement and construction supervision (EPC) for small to mid-scale natural gas liquefaction plants in the United States.

"We are extremely pleased to welcome Ron to OnQuest," says Kessler. "With his decades of industry experience and an exemplary record of successful project management, he amplifies our turnkey project management capabilities as OnQuest wins more process engineering work in the LNG and renewables sector."

Prior to joining OnQuest, Ambrosini was a principal project engineer at WorleyParsons, where he was project lead for technical peer reviews of ExxonMobil projects in Saudi Arabia and Australia, BP projects in Alaska, and Shell and THUMSCO projects at natural gas treating facilities throughout Southern California.

Before that, Ambrosini held project management roles of increasing responsibility with several engineering firms, where he led projects in diverse technologies, including residential fuel cell reformers, industrial hydrogen generation systems, post-combustion nitrogen oxides reduction systems, CLG hydrocracker units, ethylene plants, fluid-bed technology, and secondary oil recovery processing.

Ambrosini earned a B.S. in Chemical Engineering from New York University, and completed an M.S. in Chemical Engineering at City College of New York. He also received an M.A. in Education from Azusa Pacific University. He is a senior member of the American Institute of Chemical Engineers (AIChE) and holds several patents in natural gas treating processes, and he has taught college-level courses in mathematics and the sciences.
