Subsea chemical injection valve controls hydrates

Click to Enlarge

“Total control over the injection of hydrate inhibitors in oil and gas operations,” is announced to be delivered by new Roxar subsea chemical injection valve (high flow).

This new tool is designed to provide precise control over flow and chemical dosage rates of such hydrate inhibitors as Monoethylene Glycol — added to gas flow at wellheads to prevent such hydrates. It helps avoid crystals formed in high pressure and low temperature gas flows which can block pipelines and interfere with production.

Roxar valves comprise high-grade alloys and ceramics for contamination tolerance and erosion resistance in hostile operating conditions.

Models are built to operate at up to 10,000 psi and 3,000-m depths. They provide a wide adjustable flow range plus generate continuous and accurate injection rate measurements — no matter what operating conditions or pressure changes. Flow measurement accuracy at constant viscosity and temperature is better than ±5%; better than ±1% with a turbine meter version.
