High nitrogen purity: PSA nitrogen generator plants allow production of high-purity nitrogen from air, which membrane systems are unable to provide – up to 99.9995% nitrogen. But in most cases they do not produce more than 98.8% nitrogen with the remainder being argon that is not separated from the nitrogen by the usual PSA process.
The Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) is an initiative by the South African government aimed at increasing electricity generation through private sector investment in solar photovoltaic and concentrated solar, onshore wind power, small hydro (<40 MW), landfill gas, biomass, and biogas.
The cost of fuel to run a load following power plant may be relatively high, and the cost of fuel to run a peaking power plant is even higher—they have relatively high marginal costs. Operators keep power plants turned off ("operational reserve") or running at minimum fuel consumption [ citation needed ] ("spinning reserve") most of the time.
Around 81% of South Africa's energy needs are directly derived from coal [9] and 81% of all coal consumed domestically goes towards electricity production. [10] Historically this has given South Africa access to cheap electricity, but it is also one of the leading reasons that the country is in the top 20 list of carbon dioxide emitting countries.
With this variant of PSA developed for use in laboratory nitrogen generators, nitrogen gas is produced into two steps: in the first step, the compressed air is forced to pass through a carbon molecular sieve to produce nitrogen at a purity of approximately 98%; in the second step this nitrogen is forced to pass into a second carbon molecular ...
