Product Definition

By efficiently and effectively removing water and salts from the

commonly used hydrate inhibitor monoethylene glycol (MEG), the

Frames MEG recovery and WISE™ desalination process helps cut

operating and maintenance costs, while keeping the producing

wellheads in peak production.

Product Description

Together with our partner Novasep, we at Frames integrated the MEG

recovery with a newly patented waste-free inhibitor salt extraction

system (WISE™) that uses proven desalination technology to efficiently

remove salt during the MEG recovery process.

Fed into the pipeline between the producing wellhead and the receiving

facility, MEG inhibits hydrate formation in the pipeline, while also

protecting the pipes from corrosion.

By incorporating our WISE™ technology, the Frames recovery process

also removes salt that can accumulate in the used MEG. By carefully

controlling MEG salt levels, WISE™ technology helps protect the

production system from salt build-up along with any potential damage

caused by salt crystals clogging the production machinery.

Designed for demanding operating conditions

With years of experience in MEG regeneration, we

have the technical know-how to design and deliver a

unit to fit your operating environment.

Our Frames systems use industry-leading

technology to maximize heat recovery and

minimize energy consumption. This includes the

use of a heat integration system that transfers heat

from the treated MEG to the cold, untreated MEG

in order to improve system efficiency and lower

operating costs.

Clean removal of monovalent and divalent salts

A major advantage of the WISE™ technology is its

ability to remove both monovalent and divalent

salts in a single process. This efficiently removes

the destructive impact of these salts during the

common boiling process.

Process Description

Wet ‘rich’ glycol, containing dissolved salts, coming from the well is

routed to the regeneration package for purification. The MEG is initially

filtered to remove any solids caused by degradation or corrosion,

before being pre-heated by heat exchange with lean-regenerated MEG.

The heated MEG is then separated into gas and glycol in a flash vessel,

before the glycol is fed into the system’s distillation tower

for regeneration.

Water is removed by reboiling the mixture in the base of the

distillation tower. Some of the condensed vapors are used to generate

reflux in the distillation process, with the overhead vapors routed out

of the system.

Once regenerated, lean MEG is used to pre-heat the incoming MEG

stream, before being pumped to the storage tanks (by client) ready

for reuse.

During this regeneration process, a slip stream of MEG is directed

to the WISE™ desalination system to remove excess salts. Using

technology developed by our partner Novasep, fresh water is added

to the MEG in desalination columns. The water takes up the dissolved

salts, which can be safely routed directly to sea. The desalinated

MEG is then returned to the distillation tower.

WISE™ Process Principle

The WISE™ process is based on Novasep’s long-lasting experience in

ion exclusion chromatographic separation. For more than 30 years,

this technology has proven to be a continuous, robust and efficient

process for salt removal at industrial scale. Novasep has successfully

developed a patent-pending process applying ion exclusion

chromatography to glycol demineralization. Glycols and salts

have different affinities for the chromatography resins specifically

developed and selected by Novasep for this application. This

enables the separation of both components when processed

through the WISE™ unit.
