Q & A

What is the primary purpose of Myet in the context of the script?

Myet is used for performance monitoring and to predict the performance of separators in an upstream oil and gas process. It helps in determining the droplet size distribution and mist fraction, which are crucial for understanding the separation problem.

How does Myet integrate with other systems for performance monitoring?

Myet integrates with other systems by allowing clients to link process data to actively trend liquid carryover parameters and operating envelopes. This integration adds value to the overall performance simulation.

What is the proprietary modeling approach used by Myet for performance prediction?

Myet uses a proprietary modeling approach called 'Myet incremental modeling'. This approach involves incrementally quantifying what is being removed at each section of the vessel before determining the overall separation performance.

Can you explain the role of the inlet device in Myet's performance prediction?

The inlet device plays a significant role in Myet's performance prediction as it affects the droplet size distribution and mist fraction entering the vessel. Myet quantifies these parameters based on the inlet device type and pipe configuration.

What are the different types of inlet devices that can be modeled in Myet?

In Myet, different types of inlet devices can be modeled, including V-type, cyclone benches, up pipes, and down pipes, among others.

How does Myet handle the separation of gas and liquid in a vessel?

Myet performs a detailed analysis of each section of the vessel, incrementally quantifying the removal efficiency of each component. It predicts the droplet size distribution and mist fraction at the outlet of each section, which helps in determining the overall separation performance.

What is Myet Studio, and what are its main features?

Myet Studio is an application that allows users to read and design individual separators. It provides features like automatic vessel sizing, vessel weight computation, motion effects analysis, and operating envelope generation. It also supports data sheet and report generation and can link to leading simulators.

What is Myet Engine, and how does it integrate with HYSYS?

Myet Engine is a runtime engine that integrates the Myet model with HYSYS Studio within the HYSYS simulation environment. It brings the rigorous gas-liquid performance computations into the HYSYS environment, allowing the separator object to use Myet correlations instead of ideal separation or carryover based specifications.

How does Myet Studio assist in the design and analysis of separators?

Myet Studio assists by providing a detailed model of the separator's geometry and internal configuration. It allows users to define parameters for each section of the vessel, such as inlet devices, liquid levels, distribution baffles, and demisting devices. It then performs performance predictions based on these configurations.

What kind of data does Myet require for performance predictions?

Myet requires process data such as pressures, temperatures, and physical properties of the individual phases (gas, hydrocarbon liquid, and water). This data can be input manually, imported from an Excel file, or connected directly from a simulator like HYSYS.

Can you give an example of how Myet quantifies separation performance?

In the script, Myet quantifies that for the current operating condition and vessel configuration, it can remove droplets of 54 microns or bigger, with smaller droplets being carried over to the subsequent vessel. It also provides an absolute number corresponding to the droplets in ratios and the vessel's separation efficiency.
