  • Butane overhead condenser returned to original operating efficiency case study

    A Canadian energy company had fouling issues with cooling water at one of its plants that caused severe scaling in a butane overhead condenser. A 50% RYDLYME solution was recommended to dissolve the accumulated scale within the condenser. RYDLYME approach 330 gallons circulated for 6 hours at ambient temperature, reversing flow every half hour using a pumper truck. ...

  • RYDLYME improves efficiency on cooling tower case study

    A 35-ton cooling tower at a major college had compressors operating at more than 260psi just to maintain a 70°F water temperature due to heavy water scale. RYDLYME was put into the system to dissolve the scaling. RYDLYME approach 55 gallons circulated for 4 hours via inline pumps and then flushed with water. Cleaning was done while system was in ...

  • TB 48: Wolsung nuclear power plant uses liqui-cel membrane contactors for dissolved oxygen removal to prevent corrosion

    Dissolved oxygen is a leading source of corrosion in water systems. The Korean Electric Power Institute (KEPRI) has installed Liqui-Cel Membrane Contactors in the Wolsung nuclear power plant in South Korea. The membranes have been in operation since 2000 and have successfully met the rigorous demands of the nuclear power industry. The Wolsung unit 1 plant is a pressurized heavy water type reactor ...

  • How to choose a cooling bath and maintenance points

    The so-called refrigeration thermostat, as its name suggests, is a device that provides a constant temperature. In general, everyone also calls it an incubator, a thermostat, and so on. Only know enough to use the cooling bath better. Refrigeration thermostats are widely used in petrochemical, chemical and pharmaceutical, bioengineering, life sciences, light industrial foods, sample testing and ...

  • Look at How Much Electricity a Returner of the 100-Watt Water Wastes in A Month.

    Our daily electricity consumption counting is calculated by "kilowatt-hour". One kilowatt-hour is one kilowatt-hour. We first convert the power into kilowatt-hour, then multiply it by time. Take the above 100-watt as an example, 100-watt is 0.1 kilowatt-hour, and there are 24 hours in a day, 0.1 kilowatt multiply 24 hours is 2.4 degrees (kilowatt-hour), which can come to conclude that it is 72 ...

  • East coast power plant realizes 95% water recovery

    The Facility Bechtel Power Corporation builta power plant in Northampton, Pennsylvania for U.S. Generating Company. The power plant burns culm, a lower quality coal rejected from use in previous decades. By using culm as the fuel, U.S. Generating will clean up a solid disposal site. The power plant contains the usual systems including cooling towers and demineralizers that produce waste ...

  • Manufacturer of Water Treatment Chemicals and Water Additives

    Water treatment is a process for treating sewage or modern wastewater and converting it into more acceptable form for a specific end-use. The end utilization of this treated water might be drinking, mechanical water supply, water system, waterway stream support, water diversion or numerous different uses, including being securely returned to nature. Water treatment expels ...

  • It’s Time to Rethink Cooling Tower Filtration

    ABSTRACTThe dissipation of ambient or process heat in large HVAC systems, manufacturing facilities, power generation plants, refineries, metal mills and forges, chemical plants and food processors is most often accomplished by cooling towers. These simple structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. The bane of cooling ...

  • TCU temperature control model selection and technical parameter description

    TCU temperature control is also a two-cycle unit single-fluid temperature control system. When selecting the model, it is very important for the whole temperature control reaction. Only the appropriate reaction system is used to exotherm and absorb the whole reaction process. The heat responds to the entire control, so ...
