LOW PRESSURE COMPRESSION SYSTEM

“Unplanned maintenance or shutdowns put my personnel and process at risk. High operating costs and declining production prevent me from reaching the target return on our production assets.”

As offshore exploration activities continue to increase and drilling deepens, the risks to your assets compound. If your equipment isn’t running at its best in remote and extreme environments, you put your personnel at risk. Common process upsets caused by inefficient control valves can negatively impact your production uptime, increasing operational costs and the chances of a safety incident.

MAXIMIZE PRODUCTION

A lot goes into the sizing and selection of a control valve. A procedure based on sound engineering principles, coupled with real-world knowledge of your process, helps determine the valve selections that are most appropriate for your production requirements. Total comprehension of this procedure, your process, and the engineered specifications of your applications are critical to helping you reach your production targets.

By partnering with Emerson, you can work alongside a team of application experts who are dedicated to solving your toughest offshore challenges. Our engineers carry out the sizing and selection of your control valve equipment with precision for detail. This helps you reach your production targets and gain confidence in your process.

Reduce Noise and Improve Output

Gas-to-flare systems are an integral part of many deepwater offshore assets. They safeguard against the overpressure of critical equipment and are vital to the start-up, shut-down, and short-duration upsets of your offshore production platform.

Like any critical application, the gas-to-flare application comes with its challenges. Significant pressure drops and high flow rates across the valve are the primary concerns. If these issues are not taken into account during the valve sizing and selection process, excessive noise levels and even damaging vibration can occur, resulting in production interruptions, safety incidents, or environmental fines.

Emerson engineers use aerodynamic noise modeling and prediction technology to account for independent trim and valve body noise, leaving you with a customized valve solution that best fits your large pressure drop applications. This comprehensive approach incorporates field-proven, noise-attenuating valve trims, like Fisher Whisper III trim, to reduce noise and prevent damaging vibration. When you’re able to control noise effectively, you can keep production running smoothly and safely.

Laser shadowgraphs show jet independence from three properly spaced holes (left). The same three holes spaced too closely (right) show jet interaction, which leads to additional noise. Being able to predict and control jet interaction can reduce the noise produced by up to 40 dBA.

A top-down look at flow through Fisher WhisperFlo™ trim (left) using computational fluid dynamics illustrates the independence of fluid jets as they exit the cage. In contrast, the exit jets of some tortuous path trims (right) impinge upon one another in pairs, creating an additional noise source.
