Abstract Bioenergy combustion with Carbon Capture and Storage (BECCS) is a key technology to achieve carbon negative emissions power generation. This can be achieved by coupling the biofuels CO 2 capture storage (CCS). The lowest cost for CCS corresponds at moment Chemical Looping Combustion (CLC) process. use which gaseous (biomethane, biogas or syngas etc.), liquid (biodiesel, bioethanol, bio...

Turbo-expanders are used in industries for cooling, liquefaction and also power generation. An important part of these turbines is the variable angle nozzle causing a nonlinear behavior that is not well recognized among the prime movers of the dispersed generators. In this paper, at first, the turbo expander system is evaluated in details and its nonlinear behavior is investigated. Then, the sy...

A CGS is of the most important parts in natural gas transmission pipelines in which the high inlet natural gas (NG) pressure is reduced to much lower value by employing a throttling valve. This pressure drop causes hydrate forming, preventing stable NG flow through the pipeline. To prevent hydrate forming, NG is usually preheated by heaters which burns remarkable amount of NG. In this work, a n...

Over these years, people paid more attention to using renewable energy such as geothermal decrease the dependency on fossil fuel energy. Organic Rankine Cycle (ORC) can generate electricity by low-temperature heat sources, and is an ideal pollution-free source that provide continuous stable Meanwhile, turbo expander, one of essential components in ORC, has advantages high speed single-stage exp...

Low-density parity-check (LDPC) codes were introduced in 1962, but were almost forgotten. The introduction of turbo-codes in 1993 was a real breakthrough in communication theory and practice, due to their practical effectiveness. Subsequently, the connections between LDPC and turbo codes were considered, and it was shown that the latter can be described in the framework of LDPC codes. In recent...
