abb Regeneration System separating unit

Regenerative drives are capable of recovering energy and feeding it back into the network so that it can be utilized by other equipment. Everything needed for regenerative operation, such as active supply unit and LCL line filter are included in the drive. The active supply unit allows full power flow in both motoring and generating modes.

The unit consists of R8i and L filter modules. During motoring the input current flows through diodes to the DC bus of the drive system and the supply unit works as a diode bridge. In regeneration the current flows from the DC bus through the IGBTs to the supply network. The IGBTs are switched to conduct only once during each network voltage cycle.

A fully automatic sensor regeneration system is available for ultra low sodium measurement applications to ensure sensor sensitivity. In the multiple stream version, up to 3 different sampling points can be measured by a single wet-section, with the measurement results sent digitally to the transmitter.

This supply unit is used in regenerative drive systems to convert three-phase AC voltage to DC voltage. The unit consists of R8i and L filter modules. During motoring the input current flows through diodes to the DC bus of the drive system and the supply unit works as a diode bridge. ACS880-907 regenerative rectifier modules - ABB Group

SF6 Gas Recovery Unit (GRU-7) – ENERVAC INTERNATIONAL ULC Gas Recovery Unit (GRU-7) Whether you are looking for fast processing speed, better than 99.6% SF6 recovery, a 100% oil-less system, unlimited storage capacity, easy single valve operation, or portability, you will find it with the Enervac GRU-7.

Oct 20, 2016The riser reactor is the key unit in the fluid catalytic cracking (FCC) process. As the FCC feedstocks become heavier, the product mixture of oil, gas and catalysts must be separated immediately at the outlet of the riser to avoid excessive coking. The quick separation system is the core equipment in the FCC unit. China University of Petroleum (Beijing) has developed many kinds of separation

to separate gas, hydrocarbon liquids, and the produced water and MEG mixture, commonly known as rich MEG. The produced gas and hydrocarbon liquids are routed onshore for sales and further processing. The rich MEG is regenerated by the PUREMEG* MEG reclamation and regeneration unit into a lean, high-purity, salt-free MEG for reuse.

Aug 06, 2016One key component that enables regeneration in AC drives is the insulated-gate bipolar transistor (IGBT). Traditional diodes used in the inverter bridge can only handle power in one direction (incoming to the motor) and aren’t able to transfer power back to the AC source. Including IGBTs in the bridge allows power to flow in both directions.

A process for regenerating solid particulate catalyst used in fixed bed hydrocarbon conversion processes, such as the shape selective zeolite conversion of olefins to gasoline and diesel fuel. Regeneration is achieved using a portion of a flue gas stream to regenerate catalyst and preheat feedstock. Economies in equipment and operation are realized by employing a once-through configuration for

A method and a system for reproducing a calibration certificate of an electronic instrument having at least one electronic storage means, the method involving separating the calibration certificate data into a first subset of data, which is calibration specific, and a second subset of data, which is document descriptive; defining a set of meta data about the second subset of data; storing the

The cryogenic separation process requires a very tight integration of heat exchangers and separation columns to obtain a good efficiency and all the energy for refrigeration is provided by the compression of the air at the inlet of the unit.. To achieve the low distillation temperatures, an air separation unit requires a refrigeration cycle that operates by means of the Joule–Thomson effect
