Valves
Customized valves and safety instrumentation for underground LPG storage in India
Hindustan Petroleum’s LPG mined rock cavern project reaches a new milestone as equipment from Svanehøj Tank Control Systems has been shipped to Mangalore. Here, a new range of special ESVs will be used for the first time in an underground storage facility.
Innovations
Emerson has introduced the Fisher™ easy-Drive™ 200R Electric Actuator for use on Fisher butterfly and ball valves.
The concern of CO emissions
No refinery can operate without hydrogen (H<sub>2</sub>) because it is needed in all hydroprocessing technologies to remove sulfurous impurities and produce products at the correct specifications. With each passing day, the importance of H<sub>2</sub> in refineries is increasing as crude oil gets heavier and more sour while product specifications are simultaneously getting tighter.
Innovations: Electric Valve Actuator Achieves CSA Class 1, Div. 2 Hazardous Location Certification
Curtiss-Wright’s Actuation Division’s new Exlar Tritex® electric valve actuator (EVA) has achieved CSA Class 1, Div. 2 (C1D2) Hazardous Location certification. It also outperformed U.S. oil and gas producers’ expectations for rugged field test operations in Texas, Oklahoma and New Mexico.
Pellet handling system for polyolefin plants: Are you specifying it correctly?
Product pellets produced in polyolefin plants—such as polyethylene (PE) or polypropylene (PP)—require transportation from the unit to the end users that process these pellets to manufacture different end-use plastic products.
Directly calculate pipe diameters through valves and fittings under a turbulent flow regime
Calculating pipe diameters through long, straight pipes is executed in classic fluid flow problems using traditional trial-and-error methods or by complex equations.
Innovations: Digital Valve Controller Offers Embedded Edge Computing to Streamline Workflows, Optimize Performance
In late 2023, Emerson released its Fisher™ FIELDVUE™ DVC7K Digital Valve Controller, a new design improving upon 30 yr of field-proven innovation.
Practical examples and considerations in designing emergency depressurizing systems
Process operating facilities typically process large inventories of gas and volatile hydrocarbon liquids at high pressures, which have the potential of posing major hazards during emergency incidents—such as fire, loss of containment or operating excursion.
Maximum fill volume in propane, butane and LPG pressurized storage tanks
Large volumes of flammable hydrocarbons are stored inside different storage tanks in gas, oil and petrochemical plants. In addition to maximizing profitability, the optimum design of process units and storage facilities must consider safety concerns to avoid catastrophic accidents.
Optimizing combustion processes for safety and efficiency
Combustion processes are critical for producing heat and power in nearly every industry.
