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.\u003c\/p\u003e\n\u003cp\u003eProcess 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 commissioning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe company has an immense reputation in applications including the following:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRefinery Vacuum Systems\u003c\/li\u003e\n\u003cli\u003eVacuum Distillation Units\u003c\/li\u003e\n\u003cli\u003eFlash Evaporation for Seawater Desalination\u003c\/li\u003e\n\u003cli\u003eTurbine Condenser Air Extraction\u003c\/li\u003e\n\u003cli\u003eEdible Oil Processing\u003c\/li\u003e\n\u003cli\u003ePolymerisation\u003c\/li\u003e\n\u003cli\u003eCrystallisation\u003c\/li\u003e\n\u003cli\u003eEvaporative Cooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSea Water Deaerators\u003c\/h4\u003e\n\u003cp\u003eSecondary 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 rates.\u003c\/p\u003e\n\u003cp\u003eThe 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 river.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eEdwards 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 chemical scavenger.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe following options are available:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpray\/pack deaerators\u003c\/li\u003e\n\u003cli\u003ePacked column deaerators\u003c\/li\u003e\n\u003cli\u003eTrace gas stripping deaerators\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEdwards 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.\u003c\/p\u003e\n\u003cp\u003eEdwards 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.\u003c\/p\u003e\n\u003ch4\u003eHigh Pressure Feedwater Heaters\u003c\/h4\u003e\n\u003cp\u003eThrough 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.\u003c\/p\u003e\n\u003cp\u003eOur 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.\u003c\/p\u003e\n\u003cp\u003eHick 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eAccess 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 efficiently.\u003c\/p\u003e","brand":"VACPRO - Vacuum Process Solutions","offers":[{"title":"Default Title","offer_id":57531312537982,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0120\/5321\/7338\/files\/image-2026-06-10T174633.673.png?v=1781093802","url":"https:\/\/vacpro.dk\/products\/custom-engineering","provider":"VACPRO - Vacuum Process Solutions","version":"1.0","type":"link"}
