Siemens Water Technologies Saves Refinery $2 Million Annually

A West Coast refinery turned to Siemens for help to provide more consistent and reliable quality of purified boiler feedwater. The refinery, using up to 1,500 gpm of demineralized boiler makeup water, was experiencing a variety of problems including aging demineralizers, pending environmental legislation, excessive operation costs, wide variations of raw water quality and limited capital to address these issues.

Siemens Water Technologies Uses Proprietary Software Program to Provide Solutions for Industrial Water Treatment

Proprietary technology, WinCPD®, is utilized to help customers look at water treatment options from design stage to review of existing equipment.

Siemens Provides New Makeup System for a Midwest Fab

Siemens outsourcing capabilities prove valuable to semiconductor fab in the Midwest

Softeners Remove Hardness to Protect Downstream Reverse Osmosis (RO) Systems

A Midwestern company was experiencing frequent cleanings of their reverse osmosis (RO) system due to severe scaling on the membranes.

Southwestern Refinery Cleans Up Cooling System With Chlorine Dioxide

Intimate contact of process hydrocarbon with the cooling water through two atmospheric condensers resulted in severe fouling of this cooling system. Microbiological control, accomplished through use of chlorine tablets and liberal dosages of nonoxidizing biocides, was clearly inadequate. Fouling was so severe that throughput was limited. Mechanical exchanger cleaning was required every 3 – 4 months.

Successful Conversion Of Softeners And Two Bed Deionizers To Packed Bed Systems

The quantity and quality of water from an existing water treatment system were not meeting the expectations of plant personnel from a Midwestern power plant. Through EP&S (Engineered Parts and Services), the existing system was upgraded and retrofitted to become packed bed systems.

Trailer-Based Mobile DI Replaces Resin Vessels

Siemens Water Technologies provided MODI trailers that were able to meet all requirements, including flow rate and ZLD. At the same time, the customer got an easy-to-use, space-saving system that resulted in cost savings around $400,000 dollars a year.

Use of Chlorine Dioxide Enhances Corrosion Control Program at Major Southwestern Petroleum Refinery

This cooling system had unacceptably high corrosion rates: 8 - 10 mpy on carbon steel and 1 mpy on admiralty. The cause of the corrosion was a small, light hydrocarbon leak. Increased chlorine feedrates were required to keep the system in microbiological control, but also aggravated admiralty corrosion rates. Increased feedrates of azole copper corrosion inhibitor were also required since azole creates a demand for chlorine, further increases in chlorine feedrate were required. Chlorine reacts with azole, making it ineffective as a copper inhibitor, increasing requirements for azole.

Use of Chlorine Dioxide Increases Demineralizer Throughput

This industrial plant provides disinfected, lime softened Trinity River water, demineralized water and steam to a number of surrounding plants. The 1 million gallon clear well was open to sunlight, and algae grew despite the presence of free chlorine. The presence of ammonia in the water and degradation of the bleach used as the disinfectant resulted in a very high feedrate.
