ProPure was founded on February 18, 1999 by Framo Engineering AS ("FE") and Statoil, each of which held 50% of the shares of the company. In 2002 Statoil ASA took over FE’s shares and the company became a 100% Statoil owned company, organized under Statoil's Industrial Development Group I&K.

In 2004 all of ProPure's shares were transferred to Pure Process Solutions AS (PPS), a holding company jointly owned by Statoil ASA and Energivekst (a Hitec Vision company). This company was created with the ambition to rapidly become a major supplier of advanced process technology to the oil and gas industry.

In 2006 CTour Process System AS was merged into ProPure AS and named ProPure AS. The two companies, which since 2002 have been working close together in commercialisation of the CTour technology, now joined forces.

ProPure AS has established a sound reputation for providing technical services and equipment to Statoil and other leading companies in the oil and gas business. ProPure's innovative thinking, and the transfer of these ideas into practical solutions, provides customers direct results in reducing asset capital and / or operating expenditure.
