Case Studies

Acrodyne has published a series of Case Studies covering a number of product applications and solutions to projects across Australia and New Zealand.

Case Study – DBNGP Critical Compressor Station Upgrade

The Project Compressor Station 1 (CS01) Acrodyne was requested to provide a suitable solution to automate an existing manually operated bypass valve at this critical facility. CS01 is a critical pumping station facility, just South of Karratha being the first site after the upstream gas producers Woodside, Apache and Chevron.

Case Study – Profibus Network Upgrade

The Project The end user required Acrodyne to provide a solution to the control of the main inlet valves. Originally in order to change the channel direction of the main waste water flow the operator was required to manually fit stop boards.

Case Study – NEW WATER RECLAMATION PLANT

The Project The Reclamation Plant was a new plant that was an initiative during the drought period to reclaim water and thus required the supply of 18 x IP68 weatherproof quarter turn electric actuators mounted to butterfly valves that are principally isolation valves with some flow control valves.

Case Study – FUEL TERMINAL UPGRADE

The Project A leading petrochemical company required actuation of two critical isolation gate valves at their fuel transfer stations at two of their facilities. The solution was required to have SIL Certification 1 and operate to a specific cycle to prevent backflow of hydrocarbons into the pumphouse, that may cause an explosion leading to possible injury and asset damage.

Case Study – PLANT ENVIRONMENTAL UPGRADE

The Project Since the upgrade the actuation supplied on the dosing plant was repeatedly faulting. The cause was believed to be condensation and moisture affecting the electronics and in turn causing the actuators to drive past limits. The problem needed to be resolved and due to the trips occurring intermittently, it caused frustration and required the council electrician to travel considerable distances and be available 24/7.

Case Study – OH&S AQUEDUCT UPGRADE

The Project A valve on the aqueduct connecting the reservoir required actuation due to the safety concerns for the operator. Previously operators were required to walk down a steep hill with a torque leader actuator and a generator that is used as a mains power supply.

Case Study – ACTUATED ALLIGATOR VALVE UPGRADE

The Project Acrodyne was requested to provide a suitable solution to automate an existing manually operated Alligator valve. Previously an operator was required to commute to the pump station to manually operate the valve which presented three main problems: OH&S issues for the operator Inefficient use of resources Inability to gauge the amount of water released The valve was required to be controlled in a remote control room working seamlessly with a flow control device and their existing SCADA system.

Case Study – CRITICAL CONTROL ACTUATOR UPGRADE

              The Project The Power Station was experiencing challenges in better tuning their boilers. This was primarily attributed to the limited capability of the existing actuators. Acrodyne was approached to offer an option to replace actuators on the following: ID Fans (Induced Draft) FD Fans (Forced Draft) PA Dampers (Primary Air) TC Dampers (Temperature Control) Site Overview Located North of Brisbane the Power Station is a 1600 megawatt facility and it is one of the largest power stations in Queensland.

Case Study – NORTH SEA RETROFIT VALVESCAN VSD CONTROLLER

The Project The challenge that the End User expressed to Imtex was that, given the age of their assets, the necessary infrastructure to install new equipment was not currently available. Other solutions that had been presented to the End User, such as smart positioners, intelligent solenoids, or sophisticated on-line valve monitoring systems, would involve considerable expenditure on new cabling, I/O and potentially control system upgrades.

Case Study – CAMTORC TRIPGUARD SYSTEM

The Project As part of an upgrade to the flowlines into separator unit on a key asset, the engineers at a major Oil and Gas End User in the North Sea identified it was necessary to perform on-line testing, in the form of Partial Stroke Testing on one of the main Shut Down valves to be installed.

Case Study – WATER TREATMENT PLANT UPGRADE

The Project Acrodyne were contacted to replace two isolation valves on sedimentation basin inlets at the Water Treatment Plant. The original valves & actuators were unserviceable due to age, wear & tear and time was critical as the job had to be completed within the low water demand winter shutdown period which is between May – July each year.

Case Study – AUSTRALIA’S OLDEST WATER SUPPLY

Next Generation Limitorque MX on a butterfly valve The Project The plant is currently on standby, but recently the end user has show intent to upgrade the facility to enable continuous use of the Yan Yean Reservoir, particularly during summer months when demand is high. This well help meet Melbourne’s water demand and also provide storage for local emergency services such as firefighting.

CASE STUDY – VICTORIAN TOWN TAKES ACTION DURING DROUGHT

  The Project With an existing holding tank which held water from various suppliers, the local water authority decided to build a brand new purification plant. This was a new project that would enable the filtration and purification of local bore water via a Micro Media Filter system as a supplement to the town’s water supply.

CASE STUDY – QUICK DELIVERY PREVENTS DELAYS FOR POWER STATION

    The Project The end user needed to replace an existing actuated valve in operation on an isolation steam valve application due to general wear and tear. Isolation valves are a key component in any fluid system as they are used to stop the flow of fluid into a particular area of the system.

Case Study – SMELTER INCINERATOR UPGRADE

The Project Acrodyne recieved an enquiry for equipment to manage a pitch fume incinerator at BSL’s Wharf. The incinerator uses natural gas to burn off pitch volatilies while still contributing heat to the HTF circuit. Sector: Aluminium Smelter Category: Aluminium Production Products: Beck Group Electric Actuators Site Overview Boyne Smelters Limited (BSL) is proud to be Australia’s largest aluminium smelter.

Case Study – Liddell Power Station Upgrade

                The Project Acrodyne was requested to propose a suitable solution as a replacement actuator for a high temperature environment. The requirement was for the actuator to be capable of withstanding temperatures of upto 120°C.

Case Study – Major Gate Installation

The Project The Luggage point Treatment plant required the upgrade Slug Draw Off actuation and the actuation controlling the Rectangular Desludger Traveling Bridge. The criteria was for the equipment to be suitable to the continuous exposure to H2S and be capable of equipment reliability with precise communication to the control system.

Case Study – Critical Control Actuator Upgrade

              The Project The Power Station was experiencing challenges in better tuning their boilers. This was primarily attributed to the limited capability of the existing actuators. Acrodyne was approached to offer an option to replace actuators on the following: ID Fans (Induced Draft) FD Fans (Forced Draft) PA Dampers (Primary Air) TC Dampers (Temperature Control) Sector: Power Category: Coal Boiler Control Products: Beck 11-309 Electric Actuators Site Overview Located North of Brisbane the Power Station is a 1600 megawatt facility and it is one of the largest power stations in Queensland.
