Edwards has over 90 years experience in the
design and supply of steam ejector systems. Edwards has been instrumental in
the development of the steam ejector from the relatively crude single stage
devices which evolved into today’s highly efficient multi-stage systems.
Process and mechanical design expertise is
combined with project management skills for the supply of individual items of
plant, or the execution of total projects including installation and
The company has an immense reputation in
applications including the following:
Secondary recovery by means of water injection
is frequently an essential feature of crude oil production. It is often a
crucial factor in achieving and sustaining economically viable production
The source of the water is dependant on the
location of the production facility and could be from a subsurface source such
as produced water or an aquifer, or from a surface source such as the sea or a
The latter two sources, as with most surface
waters, normally contain substantial levels of dissolved oxygen. In order to
control corrosion rates in downstream plant and to inhibit bacterial growth
this oxygen must be removed before the water is used for injection.
Edwards is able to provide extensively proven
deaeration technology to facilitate the removal of this oxygen to levels such
that the remaining residual may be economically removed by the addition of a
The following options are available:
Edwards is able to offer field proven designs for water
injection deaerators, which are required to operate upstream of sulphate
removal systems. Such installations require that the deaerator must operate
without antifoam agents since the use of such agents in incompatible with the
membranes used in the sulphate removal system.
Edwards has considerable experience in the supply of deaeration
packages for use on floating production vessels, including installations on
FPSO's, semi-submersibles and on tension leg platforms.
Through its acquisition of Hick Hargreaves,
Edwards has added the capability to design and supply replacement feedwater
heaters for central power generating plants to its product portfolio.
Our capabilities in regard to this equipment
are principally focussed on the supply of replacement vertical heaters, with
full radiographic testing of the back face welded tube to tubesheet joints
being undertaken to ensure maximum integrity of these critical joints.
Hick Hargreaves began to suppy feed heaters in
the 1930’s and the reference list now extends to several hundred units. Many of
our heaters have been in service for well in excess of twenty five years.
The designs developed by Hick Hargreaves cater
for modern power station operating practices with repeated cold and warm starts
and the stresses imposed on the heaters as a result of this type of operating
regime. Well proven baffling and shrouding arrangements maximise the efficiency
of the desuperheating and condensing sections and enable effective control of
liquid levels within the heater to ensure effective condensate drains cooling.
Access to the waterbox for inspection is provided
via an arrangement designed to allow easy removal and replacement of the cover
and to provide adequate access to permit inspection to be undertaken
