Válvulas para Transporte de Pulpa Minera
En el mercado minero y metalúrgico, las válvulas deben funcionar de forma confiable durante periodos relativamente largos. Los concentrados mineros que se transportan por cañerías a grandes distancias presentan un gran desafío para las válvulas. La naturaleza abrasiva de la pulpa metálica y la acumulación de partículas asociadas a ella pueden ser una complicación para las superficies de sellado de las válvulas. La operación confiable se torna aún más crítica en zonas remotas d...
Fossil Fuel
Modern fossil fuel plants are highly complex, custom-designed systems. Emerging boiler technologies and progressive system upgrades are increasing plant capacities and changing the operating landscape. These innovations include higher temperatures and pressures found in advanced super-critica...
Compressor Protection
ProcessCompressors are a crucial part of many processes where the media requires compression in order to move along the system. These compressors are set for particular conditions where any instability in the control valve will create a system trip. In the event of a trip, the control valve must open extremely fast to ensure that the gas is recycled around the compressor to avoid internal damage to the compressor. Anti-Surge / recycle control valves should always be designed t...
Gas to Flare / Depressurization
ProcessThe objective of a flare system is to burn waste gases that are either uneconomical to recover / retain—or released during planned or unplanned over-pressuring of plant equipment. Waste gases are released to the flare via flare headers and burned as they exit the flare stackOne of the major safety issues addressed with utilizing a dependable isolation valve is flashback protection. In this situation, absolute tight shut-off is required. However if de-pr...
Dryer Sequence (Mol Sieve)
ProcessMolecular sieve dehydration (MSD) is used to remove water from natural gas. There are multiple columns filled with desiccant and the gas feed is cycled through adsorption, regeneration and cooling vessels.Engineered SolutionsMOGAS isolation valves for LNG handle high and low temperatures, entrained particulates, thermal shock and high cycling with dependable shut-off over many years of service. Valve features include:<d...
IIoT and VOM measure the bigger picture to lower costs
A few years ago, only the number of accumulated strokes and days in service were recorded during valve inspections. Today operational data already available supports end users in actively managing their equipment assets.
PTA
After 9 years with no repairs or maintenance, this MOGAS 6-inch ASME 600 Class valve was moved from PTA slurry service to another application, where it is still in service today.Purified T...
