Temperature Prediction for High Pressure High Temperature Condensate Gas Flow Through Chokes

Temperature Prediction for High Pressure High Temperature Condensate Gas Flow Through Chokes

This study developed a theoretical model for predicting the downstream temperatures of high pressure high temperature condensate gas flowing through chokes. The model is composed of three parts: the iso-enthalpy choke model derived from continuity equation and energy conservation equation; the liquid-vapor equilibrium model based on the SRK equation of state (EoS); and the enthalpy model based ...

Scale Prediction and Inhibition for Oil and Gas Production at High Temperature/High Pressure

With the advance of new exploration and production technologies, oil and gas production has gone to deeper and tighter formations than ever before. These developments have also brought challenges in scale prediction and inhibition, such as the prevention of scale formation at high temperatures (150–200 C), pressures (1,000–1,500 bar), and total dissolved solids (TDS) (>300,000 mg/L) commonly ex...

High Temperature Gas Chromatography

Gas chromatography (GC) is generally believed to be restricted to the analysis of ‘volatiles’ and is less applicable to the analysis of so-called ‘heavy’ compounds. The introduction of persilylated glass and fused silicea columns, of thermostable stationary phases and of non-discriminative injection devices in capillary GC (CGC) have made the deRnitions of ‘volatile’ and ‘heavy’ very Sexible. H...

High-Temperature Pressure Transducers

Pressure sensing systems operating at temperatures >200 °C are required for a variety of presentand next-generation applications ranging from oil field instrumentation to turbine engine control. Quite often, part or all of the sensing system must be physically removed from the hightemperature environment. In some cases, pressure translating devices and capillary tubes are used to isolate the se...
