What is Turbo Separator?

What is Turbo Separator?

Turbo Separator: Pulp Making Machine for Paper Industry Turbo Separator is a disc screen specially designed for coarse screening of primarily for pulp strainer with a high trash and flake consent like recycled paper.

How does a turbo-expander work?

The expander principle relies on converting kinetic energy to useful energy / electricity by using turbines and electrical generators. As the gas flows from the high pressure stream into the turbo-expander, the gas spins the turbine, which is coupled to a generator that produces electricity.

How does a cryogenic turbo-expander work?

The turbo-expander uses the energy removed from the gas due to the pressure drop to drive a compressor, which helps recompress the gas to sales pressure. The cold gas (− 160 °F) (− 107 °C) then enters the de-methanizer column at a pressure and temperature condition where most of the ethane-plus are in the liquid state.

What is an air expander?

Air expander is one of the key components in a CAES system because its operational characteristics determine the power conversion efficiency and the power generation during the discharge period. The performance of the expander contributes heavily to the round trip efficiency of the whole system.

What is a hot gas expander?

Hot gas expanders operate at high speeds with extreme heat differentials while being literally sandblasted by residual entrained catalytic particles. Depending upon customer requirements, expanders can deliver between 3000 hp (2.2 MW) and 60 000 hp (45 MW) of shaft power.

What is the difference between a compressor and an expander?

Expanders are the opposite of compressors. While a compressor reduces level of a signal above a set threshold, expanders reduce level of signals below a threshold.

How does a Demethanizer work?

The cooled gas and condensed liquid flow into the demethanizer tower where the gas rises and the liquid descends. The liquid product exits the bottom of the tower to be further processed as required. The cold residual gas exits the top of the tower and flows through the subcooler and into the gas/gas heat exchanger.

What is the difference between compressor and expander?

What is liquid expander?

In the liquefaction process the liquid expander turbine replaces the pressure breakdown (Jouie- Thompson) valve and converts the hydraulic energy from the cryogenic fluid into electrical power. It does so by converting the torque produced by the runners into electrical power using the shaft mounted generator.

What is a limiter used for?

In electronics, a limiter is a circuit that allows signals below a specified input power or level to pass unaffected while attenuating (lowering) the peaks of stronger signals that exceed this threshold. Limiting is a type of dynamic range compression.

What is threshold in mixing?

The threshold is the level that the signal needs to rise above in order for the compressor to begin to work. [mix, adjusting threshold] If the signal is too low or doesn’t cross the threshold, the compressor will simply allow the signal to pass through unchanged.

How does a de Ethanizer tower work?

De-ethanizer tower is the first tower in a typical fractionation train that separates ethane overhead and the heavier hydrocarbon through the bottom of the tower that are fed to the de-propanizer tower for further separation.

What is Parason Turbo separator?

Parason Turbo Separator is a disc screen specially designed for coarse screening primarily for pulp strainers with a high trash and flake content like recycled paper. The pulp stock is feed to the inlet chamber through a tangential inlet. Inlet chamber is also having a heavy reject outlet and a light reject outlet at the center of the chamber door.

What is a turboexpander and how does it work?

In a Gas Processing Plant, the purpose of the Turboexpander is to efficiently perform two (2) distinctly different, but complimentary, functions in a single machine. The primary function is to efficiently generate refrigeration in the process gas stream.

How does a turbocharger work?

Because the work comes from the expanding high pressure gas, the expansion is approximated by an isentropic (nearly constant entropy) process; the reduced pressure exhaust gas from the turbo-expander is at a lower temperature than that of the inlet gas.

What is the power rating of a turbo expander?

Typically, use of a turbo-expander makes sense only for relatively large gas flows. As a very rough indication, units currently in operation range in power ratings from about 25 kW to around 25 MW. However, some special applications have used turbo-expanders with ratings lower than 25 kW.
