CASO DE ESTUDIO

RTD´s de Turbina y Termopares

Cliente: Comisión Federal de Electricidad (CFE)

Antecedentes / Operaciones:

Proporciona la generación, transmisión y distribución de energía eléctrica a más de 27.0 millones de clientes, casi 80 millones de usuarios mexicanos.

Problema:

Durante un cierre de mantenimiento programado, la planta de CFE Rosarito necesitaba reemplazar los RTD y sensores de termopares para un número específico de turbinas. Este equipo debía ser entregado en 1 semana. El proveedor original (en Alemania) tenía un plazo de entrega de 8 semanas, lo que habría retrasado su programación y dado como resultado una pérdida importante en su producción.

Consideraciones:

Además del largo tiempo de espera, se sabía que los sensores existentes tenían una vida útil relativamente corta debido a la temperatura y la vibración producidas en el entorno de la turbina.
REOTEMP en una semana logró:

• Diseñar un sensor que coincida en función, forma y ajuste a la vez que mejore la vida útil del sensor.
• Fabricación y envío de prototipos
• Obtener la aprobación del prototipo

Solución:

Se organizó una visita al sitio para ver la aplicación y reunirse con los ingenieros del plan.
Después de la visita los prototipos de los sensores fueron diseñados y fabricados en las instalaciones de REOTEMP en menos de 1 semana. Tras la aprobación, REOTEMP construyó sensores de reemplazo para 8 turbinas para su reemplazo inmediato. Los sensores fueron instalados en mayo de 2009 y han estado en servicio sin problemas hasta la fecha.

Conax en la Industria Cementera

Sensor de Horno de Cemento

Conax ha diseñado un termopar Tipo K 8 AWG con un termopozo protector hecho de una aleación resistente al calor, a la abrasión y especialmente diseñado para soportar la rotación constante y vibración dentro de un horno de cemento.

Aplicación:

Medición de la temperatura dentro de un horno rotatorio que opera a temperaturas de 330°C con alta y continua vibración. El material que se procesa es el níquel de laterita, una irregular piedra triturada aproximadamente 6 pulgadas de diámetro, con un alto contenido de humedad. Este material es muy abrasivo.
Desafío: Esta aplicación necesitaba un ensamble de termopar lo suficientemente resistente para medir la temperatura del mineral en un ambiente muy abrasivo y de alta vibración.

Desafío:

Esta aplicación necesitaba un ensamble de termopar lo suficientemente resistente para medir la temperatura del mineral en un ambiente muy abrasivo y de alta vibración.

Solución:

Un termopar Tipo K hecho de alambre 8 AWG con los bordes aislados por alúmina. El termopar se coloca en un termopozo de Acero inoxidable 446 cédula 40 para proteger la unión de detección. Después

se coloca un tubo de protección externo al termopozo hecho de una aleación resistente al calor con diámetro interno de 1.50 pulgadas y externo de 3.00 pulgadas, soldado a una brida de acero inoxidable de 5.25 pulgadas de diámetro externo.
Además, este tubo de protección tiene a su vez un recubrimiento a base de níquel, cromo y boro de 0.05 pulgadas de espesor durante las 3 primeras pulgadas para proporcionar una resistencia adicional a la abrasión.
Impacto: El diseño de Conax proporciona al cliente un monitoreo de la temperatura del producto en un área que antes se consideraba demasiado dura para un termopar. Hasta la fecha, estos sensores han estado en servicio más de 36 meses sin fallas.

Introducing Ozone to Water Purification

17/05/2016/0 Comments/in Uncategorized/by admin

InnovaMass® 240S Multivariable Vortex Mass Flow Meter

Traditionally, chlorine has been used to disinfect water for drinking. Unfortunately, chlorine produces carcinogenic by-products called trihalomethanes (THM’s) when it reacts with organic substances in surface waters. The recent adoption of the Surface Treatment Rules by the U.S. E.P.A. places strict limits on chlorine. Because ozone produces fewer disinfecting by-products, the EPA, along with the American Water Works Association, has emphasized the use of ozone as a highly desirable water treatment alternative.

Ozone has been used for more than 100 years to purify water by oxidizing minerals such as iron, manganese and hydrogen sulfide and by destroying bacteria, viruses and cysts. It is more than 3,000 times faster than chlorine and is the most powerful microbiocide commonly available for water treatment.

Man-made ozone is formed by passing dry ambient air or oxygen through a high voltage field called a corona, which is produced inside an ozone generator. The high voltage breaks apart the oxygen molecules and causes them to reform as ozone, which is up to 13 times more soluble in water than oxygen. Ozone generators require a known mass flow rate of the oxygen or air fed into the device. This measurement is required to prevent the device from becoming saturated so that the amount of ozone produced can also be measured.

SIERRA’S SOLUTION

As the EPA’s rules on disinfecting by-products get stricter, more water treatment facilities are opting to use ozone systems for water purification instead of chlorine. Sierra’s InnovaMass® helps water treatment plants precisely measure the flow rate of oxygen entering these ozone generators.

measuring the amount of ozone produced by the ozone generator is problematic since the ozone has a short lifetime. It cannot be stored and needs a short “residence time” in the piping and flow meter. The Sierra InnovaMass vortex meter is an in-line device that is fully flow-profile compensated, so that minimal straight-run piping is required. Ozone is also produced at low pressures, so pressure drop losses must be minimized. The Sierra Vortex meter does not appreciably obstruct the pipe so pressure drops are also minimal.

The generator requires a robust flow device that is well shielded from the Coronal discharge that produced the Ozone. Housed in an explosion-proof enclosure, the Sierra InnovaMass vortex meter is virtually immune to the heavy electromagnetic interference (EMI) an ozone generator can produce.

Here’s what makes Sierra’s InnovaMass 240S an ideal choice:

Provides five process variables (mass flow, volumetric flow, pressure, temperature and density) at a single measurement point
Built-in pressure, temperature and flow profile compensation
All parameters are field adjustable and include complete field diagnostics
pproved for FM, CSA and ATEX
