Intek Congratulates NASA on its 60th Anniversary

On October 1, 2018, the National Aeronautics and Space Administration (NASA) celebrated 60 years of discovery, exploration and innovation. Several organizations, including Intek, joined in congratulating NASA for all of their accomplishments in research and space exploration over the years that have resulted in countless advancements in our everyday technology. To view some brief videos summarizing these accomplishments, visit NASA’s 60 Years and Counting page.

Intek has a long history of successful projects working with NASA. Through our partnership with Boeing, Intek developed liquid ammonia flow meters and temperature sensors for the Active Thermal Control System on the International Space Station (ISS), which led to several other projects for the ISS. This success resulted in several projects with NASA where Intek developed monitoring and control instrumentation for the Space Shuttle program. For a complete description of the projects completed for NASA, click HERE

Intek was one of several organizations that participated in a special anniversary edition of USA Today to commemorate the anniversary. Click HERE to view the USA Today Special Edition ‘NASA at 60’ (see our ad on page 44).

Intek Earns Certification for ISO 9001:2015

Effective September 8, 2018, Intek, Inc. was certified under ISO 9001:2015 standards by the International Organization for Standardization (ISO). Intek originally earned certification under ISO 9001:2000 in 2004 and has been audited and registered since that time by MCNA (Management Certification of North America).

Intek Quality Manager Collin Eckel said, “We are excited to earn this newest certification and believe it speaks to the culture of ‘Process Excellence and Continuous Improvement’ here at Intek. We strive daily to exceed our customer’s expectations in all areas and this certification speaks to that ongoing commitment.”

Intek began the internal process of re-certification in 2015, by comparing existing procedures against the new requirements. Since the company was already certified under the 2008 standards of performance, only minor adjustments were required to the processes in place to meet the new standards.

ASME Heat Exchanger Committee selects paper presented by Dr. Tim Harpster for publication

The paper presented by Dr. Tim Harpster at the ASME 2017 Power & Energy Conference, “Instrumentation for the Advancement of Shell and Tube Heat Exchanger Design or for Implementing an Upgrade via a Retrofit Process”, was selected as the best paper for publication by the organization’s Heat Exchanger Committee.

The paper describes a new approach for designing and implementing upgrades to shell and tube condensers for improved performance using advanced instrumentation and analysis. The paper can be viewed and downloaded by clicking here: Instrumentation for the Advancement of Shell and Tube Heat Exchanger Design.

ILS-Integrated Lab Solutions Uses Rheotherm Model 210
in High-Temperature Reactor

ILS-Integrated Lab Solutions, based in Berlin, solved a difficult application challenge in their Vinyl Acetate Monomer Reactor using Intek’s Rheotherm Model 210. The process, which involves extremely high temperatures and low flow rates, could not be controlled using most commercial thermal mass or Coriolis mass flow controllers. The application required the selection and integration of both a flow sensor and a control valve capable of handling both the high temperature and the corrosive acid used in the process. They chose to use a high-temperature Intek flow meter combined with an Equilibar dome-loaded multiple orifice control valve.

Condenser Monitoring Instrumentation Identifies Abnormal Condition

This article describes how Intek’s condenser instrumentation, which was installed to monitor condenser performance at East Kentucky Power Cooperative’s Spurlock Generating Station, helped the plant to identify an abnormal condition caused by debris in the cooling water before it caused major damage to the system.

Condenser Performance Response to Air Ingress (Air In-Leak) and Exhauster Operation

In this article, Intek engineers explain how the measurement of a new parameter provided exclusively by Intek’s RheoVac Air In-Leak Monitor can help identify the source of condenser performance issues including excess back pressure, reduced heat rate and output, increased DO and other performance-stealing problems.

Power Magazine article: Improve Condenser Performance Through Better Instrumentation

This linked article discusses the value power generation plants receive from having appropriate online monitoring of plant parameters. One of the Case Studies looks at a plant’s experience with real-time air in-leakage monitoring. Read more by clicking here.

Installation of Steam Side Retrofit Results In Lower Condenser Pressure (0.6-1.0″ HgA)

Performance study by Intek on an Ingersoll Rand and a Westinghouse condenser concluded that the condensers were under performing. Intek’s advanced instrumentation subsequently identified air storage in the steam space as the main culprit for the poor performance. A condenser retrofit to both units designed by Intek and installed during a retubing outage eliminated the air storage and significantly improved condenser performance.

Circulating Water Flow and Fouling Meters: A New Tool for Reducing Back Pressure

An article originally published in Energy-Tech magazine highlighted the valuable information provided by Intek’s unique Circulating Water Flow and Fouling (CWFF) meters. Part of the Rheotherm family of precision flow instruments used in power plants, these CWFF meters gave the subject power plant a look at the water flow conditions in the circulating water system in an effort to combat microbiological influenced corrosion. In addition, a clearer picture was obtained of circulating pump operation, debris flushing efforts, and eductor plugging.

Helping a Nuclear Power Plant Solve a Problem

Based on Intek’s extensive experience with condenser operation and design, a nuclear power plant came to Intek for a solution to their unique problem. An issue encountered during outage work in the condenser needed to be accurately, and quickly, analyzed. A thorough analysis of the problem, with a specific recommendation was provided within a week.

Optimizing Condenser Performance: A Case Study

Intek undertook a project to improve the performance of a 37 year old condenser during a retubing outage. Since coming back on line after the retrofit, the plant has achieved record low condenser pressures for equivalent operating conditions, record low condenser condensate DO levels below 4 ppb, a 200% increase in polisher resin life, and a 6% heat rate reduction for the two years following the retrofit outage.
