Hick Hargreaves products integrated into Edwards portfolio
CRAWLEY,
UK (5 January 2010) - Following its acquisition of the well-known Bolton,
UK based engineering company Hick Hargreaves & Co Ltd in 2001, leading
vacuum technology business Edwards has integrated the Hick Hargreaves range
of steam ejector systems, water injection deaerators and high pressure feed
heaters into its product portfolio.
The well proven products, which are widely used in the petrochemical, oil production and power generation industries worldwide, are now available through Edwards' Bolton, UK office. All aspects of sales, engineering, contract management and procurement activities relating to these products are undertaken by a dedicated process vacuum team, which maintains a large core of Hick Hargreaves staff and is independently ISO 9000 accredited in its own right.
Ejector systems
Hick Hargreaves has been instrumental in the development of steam ejector
systems since their introduction in the early 20th century. Today's complex
and highly sophisticated systems are designed and validated using data accumulated
from the Hick Hargreaves steam test bed and from extensive site tests on
operational units.
Steam ejector systems are used in a wide range of industrial applications, including refinery vacuum systems, vacuum distillation units, flash evaporation for seawater desalination, turbine condenser air extraction, edible oil processing, polymerisation, crystallisation and evaporative cooling. Each Hick Hargreaves ejector system is individually designed to suit the customer's specific requirements.
Proprietary heat transfer software has also been developed through research programmes with leading UK universities and operating results from commissioning work and from plant operators. This is used to model the condensation processes within the condensers, which may include complex hydrocarbon and water vapour mixtures in association with non-condensable gases. As a result, the Hick Hargreaves ejector systems can be designed to maximize condenser efficiency and hence ensure size and operating costs are kept to a minimum.
Water injection deaerators
Edwards also provides the complete range of Hick Hargreaves deaeration equipment,
including seawater deaeration packages for use in water injection systems.
Designs include conventional packed column vacuum deaerators and the unique
spray packed vacuum deaerator, which uses patented spray distributor technology
in conjunction with high mass transfer efficiency packed beds to reduce
column height and weight and increase efficiency on floating installations
such as FPSOs (floating production, storage and offloading vessels) and
semi-submersibles.
Hick Hargreaves vacuum deaeration packages have been widely used upstream of sulphate removal packages, an application which requires a deaerator design capable of operating successfully without any requirement for antifoam dosing.
Proven designs of inert gas stripping, steam stripping and trace gas assisted deaerators are also available and can be used in applications where a Hick Hargreaves vacuum deaerator may not be the optimum choice.
There are over 160 Hick Hargreaves water injection deaerator units in operation throughout the world, with many units having been in continuous service for more than twenty five years. The company's reference list includes most leading oil companies.
Feedwater heaters
Hick Hargreaves high pressure feedwater heaters have been used in central
power generating stations around the world for over seventy years. They
use back face welded tube to tubesheet joints, which enable each critical
joint to be fully radiographed during manufacture of the heater to ensure
longevity once installed. The flows within the heater and the condensate
collection are carefully arranged to maximize the efficiencies of the desuperheating,
condensing and drains cooling sections.
"Hick Hargreaves products have proved themselves in applications worldwide over almost 100 years, and we are delighted that these have been included in the Edwards portfolio," said Peter Raynerd, Business Manager - Process Vacuum at Edwards. "We encourage engineering contractors to contact us to discuss their specific requirements, and our experienced team will be happy to provide a design tailored to their needs."

Produkte von Hick Hargreaves in Portfolio von Edwards aufgenommen
CRAWLEY, UK. (28. Juni 2010) — Edwards, führendes Unternehmen im Bereich Vakuumtechnologie, hat die Dampfstrahlsysteme, Wasserstrahl-Entgaser und Hochdruck-Vorschubheizer des von Edwards übernommenen Maschinenbauunternehmens Hick Hargreaves & Co Ltd in sein Produktprogramm übernommen
Die bewährten Produkte, die weltweit vielfach in der petrochemischen Industrie und bei Energieerzeugern eingesetzt werden, sind jetzt über die Niederlassung von Edwards in Bolton, GB, erhältlich. Alle Aspekte des Vertriebs, der Technik, der Vertragsabwicklung und der Beschaffung dieser Produkte werden von einem speziellen Team für Vakuumprozesse übernommen, zu dem viele Mitarbeiter der Kernbelegschaft von Hick Hargreaves gehören und das nach ISO 9000 zertifiziert ist.
Strahlersysteme
Hick Hargreaves war an der Entwicklung von Dampfstrahlsystemen seit deren Einführung zu Anfang des 20. Jahrhunderts beteiligt. Die komplexen und hoch entwickelten modernen Systeme werden auf der Basis von Computersimulationen entworfen. Die Systeme werden auf dem von Hick Hargreaves entwickelten Dampfprüfstand sowie in weiteren umfangreichen Tests vor Ort geprüft.
Dampfstrahlsysteme werden in einer Vielzahl von Industrieanwendungen eingesetzt. Dazu zählen Raffinerie-Vakuumsysteme, Vakuumdestillationsgeräte, Schnellverdampfung bei der Meerwasserentsalzung, Entlüftung der Kondensatoren von Turbinen, Speiseölverarbeitung, Polymerisation, Kristallisierung und Verdampfungskühlung. Jedes Strahlersystem von Hick Hargreaves wird individuell entworfen, um die spezifischen Anforderungen des Kunden zu erfüllen.
Zudem wurde eine eigene Software zum Wärmetransfer über Forschungsprogramme mit führenden britischen Universitäten und auf der Grundlage von Betriebsergebnissen aus Inbetriebnahmen sowie der Erfahrungen von Anlagenbetreibern entwickelt.
Diese wird dazu verwendet, ein Modell der Kondensationsprozesse in den Kondensatoren zu erstellen, die komplexe Kohlenwasserstoff- und Wasserdampfgemische in Verbindung mit nicht kondensierbaren Gasen enthalten können.
Die Strahlersysteme von Hick Hargreaves können daher so konzipiert werden, dass die Kondensatoreffizienz optimiert wird und somit sichergestellt ist, dass die entscheidenden Parameter wie Dimensionen und die Betriebskosten so gering wie möglich gehalten werden.
Wasserstrahl-Entgaser
Edwards bietet außerdem das gesamte Sortiment von Entgaserausrüstungen von Hick Hargreaves (einschließlich Bausätzen für die Meerwasserentgasung) zur Verwendung in Wasserstrahlstemen an. Im Sortiment sind sowohl herkömmliche Füllkörpersäulenentgaser als auch die einzigartigen Sprüh-Füllkörper-Vakuumentgaser enthalten, welche die patentierte Sprühverteilertechnologie in Verbindung mit effizienter Füllkörperschüttung für hohe Stoffübertragungsraten einsetzt, um Säulenhöhe und -gewicht zu verringern und die Effizienz von schwimmenden Installationen zu steigern, wie beispielsweise FPSOs (schwimmende Produktions-, Lager- und Entladebehälter) und Halbtaucher.
Vakuumentgasereinheiten von Hick Hargreaves wurden vielfach für den vorgeschalteten Betrieb vor Entschwefelungseinheiten eingesetzt, eine Anwendung, bei der ein Entgaser erforderlich ist, der ohne Antischaummitteldosierung erfolgreich betrieben werden kann.
Außerdem sind weitere bewährte Entgasermodelle für die Aufbereitung mit Inertgas, Dampf und Spurengasen erhältlich, die bei Anwendungen eingesetzt werden können, bei denen ein Vakuumentgaser von Hick Hargreaves möglicherweise nicht die beste Wahl darstellt. Weltweit sind mehr als 160 Wasserstrahlentgasereinheiten von Hick Hargreaves in Betrieb, von denen viele seit über 25 Jahren kontinuierlich ihren Dienst versehen. Die Referenzliste des Unternehmens enthält die meisten führenden Ölgesellschaften.
Hockdruck-Vorschubheizer
Hochdruck-Vorschubheizer von Hick Hargreaves werden seit über siebzig Jahren weltweit in zentralen Kraftwerken eingesetzt. Sie verwenden Verbindungen von auf der Rückseite geschweißten Rohren zu Rohrplatten. Hierdurch kann jede kritische Verbindung während der Produktion des Vorwärmers geröntgt werden, um eine lange Lebensdauer nach der Installation sicherzustellen. Die Durchflussmengen innerhalb des Vorwärmers und die Kondensatsammlung werden sorgfältig angepasst, um die Effizienz der Bauelemente für das Abführen von Überhitzungswärme, die Kondensierung und die Abwasserkühlung zu optimieren.
„Produkte von Hick Hargreaves haben sich seit fast 100 Jahren in Anwendungen weltweit bewährt, und wir freuen uns, dass sie in das Portfolio von Edwards aufgenommen wurden“, so Peter Raynerd, Business Manager – Process Vacuum bei Edwards. „Wir laden Firmen mit entsprechenden Aufgabenstellungen ein, mit uns Kontakt aufzunehmen, um ihre speziellen Anforderungen zu besprechen. Unser erfahrenes Team freut sich darauf, Ihnen einen auf Ihre Bedürfnisse zugeschnittenen Entwurf anzubieten.”
