New Corrosion Protection Technology for Refinery Steam Systems
GE (USA) recently announced a new corrosion protection technology specifically designed for refinery boiler and steam condensate systems. GE’s Steamate low salt amine (LSA) product series offers enhanced steam-side corrosion protection while providing greater reliability to the crude unit distillation process.
Water quality can significantly affect refinery operations, including boilers, cooling units and heat recovery systems, having a direct impact on the equipment. GE’s Steamate LSA product series is made up of proprietary blends of volatile amines in combination with GE’s unique polyamine surface corrosion inhibitor. This new technology is cost-effective and will provide corrosion protection of refinery boiler and steam-condensate systems while minimising the potential for formation of corrosive amine salts in crude distillation units where utility steam is used in crude processing.
Corrosion can threaten the reliability and safety of critical refinery equipment, raise maintenance costs, reduce process runtime and jeopardise product quality. In addition, corrosion control is becoming more important as refiners around the world turn to lower-cost "opportunity" crude oil feedstocks and often work to maximise middle distillate production. The GE Steamate LSA series offers a powerful dual corrosion protection feature with a high- performance neutralising amine package in combination with the polyamine surface corrosion inhibitor to provide enhanced corrosion protection in areas that have historically plagued refiners, such as reboilers and users of low-pressure flashed steam. More importantly, the refiner will not be restricted in operation because of crude unit distillation concerns around corrosive and unwanted amines being introduced from the utility steam treatment.
“GE’s new Steamate LSA technology will provide increased reliability and cost savings through the reduced potential for corrosion failures and production interruptions in boiler, steam condensate and crude distillation units,” said Ava Drayton-Elder, water services global product management leader—water and process technologies for GE Power & Water. “Steamate LSA is ideal for refineries, as it offers advanced corrosion protection technology.”
Shimadzu (Germany), world specialists in analytical instrumentation, has released the Hyper Vision HPV-X video camera, a top-of- the-line high-speed product. The HPV-X allows observing previously unobservable ultra-high-speed phenomena with high temporal resolution. The camera is applicable to a broad range of fields requiring high- speed video, such as research in advanced science, engineering and medicine, space technology development, product development, and the identification of the causes of defects.
As Shimadzu's flagship model, it offers: recording speeds of up to ten million frames per second (in HP mode = half pixel mode (50,000)); storage capacity for up to 256 frames (in HP mode); high resolution of up to 100,000 pixels per frame at ultra-high speeds (in FP mode = full pixel mode (100,000)).
These features mean the camera can be used to analyse ultra-high-speed phenomena in even more detail.
Just like the previous model, the simple system configuration offers a compact and highly portable design that makes on-site setup especially easy. The HPV-X camera head just has to be connected to a laptop computer by cable. The camera also retains the same HPV software that has been so popular with current users, with intuitive features and easy-to-understand setting screens making it easy to capture ultra-high- speed video.
The HPV-X can record 128 frames, which is 20 % more than the previous HPV-2 version. In the HP mode (50,000 pixels), a double- memory function enables recording 256 consecutive frames for recording even longer periods. This gives the user the choice to either prioritise resolution or recording time.
Typical high-speed cameras require lower resolutions as recording speed increases, but the HPV-X maintains the same high resolution even if the recording speed is increased. That means ultra-high-speed phenomena can be analysed in far more detail than when using a regular high-speed video camera. This proprietary feature is included in all Shimadzu’s Hyper Vision high- speed video cameras, but is not available from any other manufacturer. The HPV-X is able to record five million 100,000 pixel images per second or ten million 50,000 pixel images per second.

Utilising the latest advancement of GE’s LoSalt simulator software, the proven neutralising amines in Steamate LSA were chosen for both optimum cost performance in the boiler and steam system and compatibility with the refinery crude distillation process. Specifically, they were selected to minimise the potential for formation of corrosive chloride salt deposits throughout the refining process where boiler steam is used in crude processing.

Handheld Infrared Oil Analyser Provides Direct, Immediate Measurement of Lubricant Condition
Lubrication abnormalities are a major cause of equipment downtime and failure. To prevent those costly occurrences, the FluidScan Q1100 handheld infrared oil analyser from Spectro Inc. (USA) enables users to determine when oil is no longer fit for use due to liquid contamination or degradation. The compact instrument provides direct, immediate measurement of water, total acid number (TAN), oxidation, glycol, total base number (TBN) and other parameters via Spectro’s patented Direct Infrared Spectroscopy (DIR) technology. DIR operates without wet chemistry and requires no solvents; only one drop of oil is needed for analysis. In addition, the unit’s patented flip-top design speeds test preparation and cleanup.
Routes, similar to thermography or vibration routes, can be downloaded from the Emerson AMS Suite’s OilView software to the Q1100. Results can be uploaded back into OilView. Oil data can be analysed, along with data from other predictive maintenance techniques, in the Emerson AMS software for Machinery Health Management. The Q1100 includes a large and expandable reference library of industrial mineral and synthetic lubricants for gearboxes, turbines, compressors, and hydraulic systems.
Spectro president and CEO Brian Mitchell says, “The FluidScan Q1100 provides a compact, easy to use and powerful entry product for customers seeking to adopt or expand their onsite oil analysis activities. It also extends the oil analysis capability for existing users of the Spectro 5200 TriVector Oil Analyser by enabling route-based oil analysis and an interface with OilView and AMS Suite Asset management software.”
