Fouling in hydrogen recycle gas compressors
Hydrogen recycle gas compressors are one of the most significant rotating equipment in oil refineries, petrochemical plants and upgraders.
Mitigation actions to prevent vibration during factory tests of SAGD boiler feedwater pumps
The most vital information on the condition of boiler feedwater (BFW) pumps is vibration.
Calculate the MTBR of pumps in an oil refinery
Mean time between repairs (MTBR) is an index for judging the performance of a specific piece of equipment.
Dual-mechanical seal arrangement for hot pump service
Selecting mechanical seals for hot services in an oil refinery or petrochemical plant is always a challenging task—and it is a task that needs careful attention, since the wrong seal selection can have a significant impact on pump reliability and availability.
Double-suction centrifugal compressor in ethylene plant inlet piping design
Centrifugal compressors are designed with different suction nozzle orientations and impeller layouts in casing.
Connecting rod failure in a new reciprocating gas compressor
Compressor failure in an oil refinery can have severe consequences on health, safety and the environment.
Design atmospheric aboveground storage tanks for accident prevention
The design and construction of oil, gas and petrochemical facilities is continuously improving, as increasing compliance with ever-changing codes and standards, such as the American Petroleum Institute (API) and the National Fire Protection Association (NFPA), is resulting in fewer atmospheric above-ground storage tank (AAST) accidents.
