This company has developed a system of highly advanced rocking cells for testing low dosage hydrate inhibitors (LDHIs) that are designed to withstand H2S gas.
The two six-cell modules are composed of highly corrosion-resistant Hastelloy, so that LDHI testing can be conducted using H2S. According to the manufacturer, “the system is the first of its kind and offers deepwater, ultra deepwater and land based operators the first opportunity to properly and safely simulate the conditions in a sour system without causing damage to the equipment.”
The 12 test cells feature dual sapphire viewing windows and proximity sensors, as well as a center-ported configuration that is designed to eliminate the problems associated with more traditional end-ported designs where hydrate formation can occur in the inlet tubing, causing inaccurate results. This new design gives much more accurate pressure readings, essential to hydrate testing, while providing a relative viscosity measurement from the proximity sensors.
