Dow and Johnson Matthey Davy Technologies License LP Oxo Technology to PetroChina

Gerald Ondrey

Johnson Matthey Davy Technologies (JM Davy; London, U.K. www.davyprotech.com) and The Dow Chemical Company (Midland, Mich.; www.dow.com) announced that PetroChina Guangdong Petrochemical Co., a subsidiary of PetroChina Company Ltd. (PetroChina), China's largest oil-and-gas producer and distributor, has selected LP Oxo Technology to produce 2-ethylhexanol, n-butanol and iso-butyraldehyde in its major petrochemical complex in Jieyang, Guangdong, China.

The new LP Oxo unit, with a capacity of 85,000 metric tons per year (m.t./yr) of 2-ethylhexanol, 235,000 m.t./yr of n-butanol and 33,000 (m.t./yr) of iso-butyraldehyde, will adopt JM Davy and Dow's LP Oxo Selector 10 Technology with advanced liquid phase hydrogenation which features a high conversion of propylene to alcohols, low capital investment and easy operation.

PetroChina enjoys a long history of cooperation with JM Davy & Dow and their predecessors in the field of oxo alcohols licensing, whose first technology-licensing project can be traced back to Petrochina Daqing project, which started up in Heilongjiang province in 1986. At that time, JM Davy, in collaboration with Dow, licensed PetroChina Daqing Petrochemical Company a ~90,000-m.t./yr butanol and 2EH plant, which was later retrofitted and expanded. In addition to the Daqing projects, JM Davy & Dow's LP Oxo Technology has been licensed to Petrochina projects in Jilin and Chengdu.

LP Oxo Technology is a low-pressure hydroformylation process that is most commonly used with propylene and synthesis gas (a mixture of hydrogen and carbon monoxide) to produce normal- and isobutyraldehydes. These butyraldehydes are then converted into 2-ethylhexanol (2-EH) and normal- and isobutanol. Additional applications of the LP Oxo Technology include a process for producing 2- propyl heptanol, a growing plasticizer alcohol alternative to 2-EH, from mixed butene streams and a process for producing C12 to C15 surfactant range alcohols from C11 to C14 Fischer-Tropsch olefins. The technology is also applied as a component of a process plant for converting heptene-1 that has been extracted from Fischer-Tropsch products to co-monomer grade octene-1. In 2011, JM Davy and Dow celebrated their 40th anniversary in collaborating in the field of LP Oxo Technology development and licensing. Over the course of those 40 years, JM Davy, Dow and their predecessors have licensed the LP Oxo Technology into 52 projects at 40 plants in 15 countries on four continents.
