EDGE Desalters/Dehydrators History

Howe Baker Engineers originally developed their proprietary electrostatic separation processes in about 1950. During the period of 1950 to 1975 , Howe Baker developed their Two‐Grid electrostatic separation systems and completed many successful installed desalter plants. About 1975 and continuing through 1995, Howe Baker improved the electrostatic design of their Two‐Grid systems with the advancement of the Tri‐Grid process. After many fit for purpose installations utilizing the new Tri‐Grid process, in 1995, Howe Baker once again added advances too their proprietary processes and developed the EDGE™ [Enhanced Deep‐Grid Electrical] system.

In 2000, Howe Baker Engineers was purchased as a whole by Chicago Bridge & Iron [CB&I]. The electrostatic separation group was a portion of that acquisition.

In 2005 CB&I exited the electrostatic market when Cameron purchased the electrostatic separator product line of business entirely from CB&I. This transaction included all electrostatic processes previously developed by Howe Baker Engineers including the latest developments of the EDGE™ desalter lines of products and equipment.

On January 19, 2010, Allied Technology closed on the transaction to purchase the entire Howe Baker electrostatic separator line including the EDGE™ desalter lines of products and equipment from Cameron – precisely what Cameron had purchased from CB&I. This sale also included exclusive rights to Natco’s dual frequency technologies.

August 2, 2010, Forum Energy Technologies (FET) announced the merger of five separate companies, Forum Oilfield Technologies, Triton Group, Subsea Services International, Global Flow Technologies, and Allied Technology, to form Houston Based FET.

In 2011 Forum developed the EDGE II as a next generation, between the grid style, electrostatic separator.

2012 Forum delivers its EDGE II technology to a major gulf coast refiner to better process opportunity crudes. It continues to meet and exceed performance specification.

There are currently hundreds of units in operation worldwide with at least one half of those in refinery downstream applications.
