UWC Helps LNG Plant Save Water And Lower Costs

A Middle Eastern liquid natural gas (LNG) facility can conserve around 3 million gallons of treated water daily by following recommendations from a water operations audit conducted by United Water Consultants (UWC), which was completed in early 2017. The lower water demand would also decrease the plant’s seawater desalination costs.

In this project, Dr. L. Fred Roensch, a founding principal in UWC, identified strategies to save an estimated 20% of their annual water treatment costs by adjusting the plant’s operation and water treatment, including the condensate system and boiler water pretreatment. The audit also recommended adjusting the cooling water chemistry to improve corrosion and microbiological control.

Paul Puckorius, another of UWC’s founding principals, said the treatment modifications would provide the LNG facility with greater protection of its assets and improve plant reliability. He noted that the study involved a thorough examination of the facility’s overall water systems, including seawater desalination, in addition to a review of the current approach to pretreatment, boiler and cooling water treatment, and water usage.

UWC is currently assisting two large power plants in Asia to prepare for a switch from a municipal water supply to one of reuse, in the form of treated wastewater. This change will provide more drinking water for the city near the power stations. UWC also has several consulting projects underway in the United States, including a power plant and a cooling water compressor station.

These projects are examples of the domestic and international services provided by UWC, which began in late 2015. UWC’s principals are Mr. Puckorius, Dr. Roensch, Mr. Jack Bland, and Ms. Jaclynn Peterson.

UWC provides water treatment consulting services through its principals and associates, who include Bob Cunningham, Dr. Jack Kelly, Kevin Lambert, Dr. Mike Trulear, and other water experts. Mr. Puckorius said UWC’s water expertise ranges from influent to effluent, siting specific systems such as pretreatment, potable, process, boiler, cooling, waste, and reuse. Examples of types of endusers UWC will work with include chemical plants to hospitals, data centers to power plants, and breweries to refineries.

UWC’s domestic and international consulting services include Legionella prevention and Water Management Plans, diagnostic studies, third-party evaluations of treatment programs, RFQ evaluation and preparation, industry specific training, technical support and audits, water sustainability, regulatory and environmental compliance, and litigation support.

“The aim of the services we provide is to offer an unbiased and high level of consulting to the water industry,” Mr. Puckorius said.

The company’s corporate office is in Richmond, VA. UWC also has locations in Denver, CO, and Sebring, FL. For more information, visit www.UnitedWaterConsultants.com.
