TIORCO provides “state-of-the-art”
processing equipment for implementing all TIORCO processes. This
reflects more than 25 years of experience developing reliable
and cost effective equipment.
When polymer technologies were first developed, one of the greatest
challenges to using the new technology was overcoming frustrating
problems with mixing dry polymer. To assure necessary purity and
ease field handling, as well as reduce transportation costs and
the risk of shelf-life loss, polymers are delivered to the oil
field in dry form. The unique physical characteristics of dry
polymers, however, such as dusting and difficult particle wetting,
require special attention in field handling and processing.
POL-E-DUC®
Systems
Since 1977, TIORCO has dedicated its resources
to increasing crude oil production from the world’s oil fields
with engineered chemical recovery processes. Critical to achieving
successful results is proper field implementation of the IOR process.
The key piece of equipment to do so has become the POL-E-DUC®
Feeder for wetting and mixing dry polymers.

The POL-E-DUC Feed System
was designed in the mid-1970s to solve the problem of mixing and
metering dry polymer in the field. Since the feed system’s
introduction in the 1970s, many improvements have been made and
now mixing and injecting polymer is routine.
The reason the feed system works so effectively is the POL-E-DUC
Dispersion Device (PDD). The PDD automatically transfers the dry
polymer to a wetting zone by using a vacuum created when the water
energizes the PDD. Because of the pressure difference created
by the PDD, the dry polymer particles are instantaneously wetted
in a high energy area.
The POL-E-DUC Dry Polymer Feed System was developed for normal
installation in the waterflood plant. It continues to be fabricated
by dry polymer users who could not obtain the existing commercial
system reliability factors and dissolution performance needed
to optimize dry polymer injection. POL-E-Duc Series A models are
engineered to automatically feed and disperse difficult to wet
dry polymers, wettability agents, surfactants and biocide chemicals.
These systems can be programmed for any automated application
requirement and interfaced to plant master control panels.
POL-E-DUC Series L models are engineered specifically to feed,
disperse and activate emulsion and solution polymers. These units
are ideally suited for water treatment, wastewater treatment,
industrial processes, food processes and mining operations.
Mobile Injection
Plants
TIORCO also utilizes the POL-E-DUC®
Dry Polymer Feed system in its mobile injection plants, which
were designed specifically for on-site preparation and placement
of WATER-CUT® and CDG gel processes, and the TIOR-KOH®
clay stabilization process. The TIORCO mobile plants are complete,
self-contained chemical preparation and injection plants that
include full instrumentation and microprocessor-based controls
for integrated, automated operation of all plant systems. In addition,
TIORCO has produced and sold mobile injection plants for use in
China and Russia.

Water Quality
Control Station
The importance of water quality on TIORCO
projects can never be over stressed. Water quality monitoring
is a TIORCO service vital to the success of any improved oil recovery
program. TIORCO developed the Water Quality Control Station (WQCS)
for diagnosing problems with scale, corrosion, solids carryover,
and fluid sampling for quality control of IOR processes. Two biocides
compatible with polymer processes to control bacterial growth
and contamination were introduced by TIORCO.
By incorporating a Water Quality Control Station at waterflooding
projects, TIORCO provides continuous monitoring and reporting
of injection fluid quality. The WQCS permits detection of both
intermittent and continuous water quality problems related to
various forms of corrosion, water-formed scale precipitation,
dispersed oil carryover and other suspended solids that cause
rapid and costly injection and wellbore plugging.
