A C02 Controller for Greenhouses
Transactions of the ASAE, 1979ABSTRACT AC02 controller for greenhouses was designed and experiments were conducted to determine its capa-bility to control C02 enrichment under the changeable weather of the southeastern United States. The inex-pensive solid-state controller was designed to turn on a natural-gas C02 generator when solar radiation was above the setpoint of 14 W/m2 and

Experimental determination of vapor-liquid equilibria of C02 + limonene and C02 + citral mixtures
The Journal of Supercritical Fluids, 1995Abstract By using an infrared absorption method together with a synthetic method, experimental results on the phase behavior of CO 2 -limonene and CO 2 -citral binaries have been obtained. Experiments were performed in the temperature range 310–323 K and in the pressure range 7–10 MPa for the CO 2 -limonene mixture and from 310 to 330 K in the ...

C02 and climate: a missing feedback?
Nature, 1989THE potential of changes in cloud properties to modulate climate perturbations is well known1,2. Changes in cloud amount and cloud height3, cloud radiative properties4–6 and cloud condensation nuclei7 (CCN) have all been recognized as possible sources of climate feedbacks. Here we report results of simulations that indicate that the changes of state of

, 2000 The market mechanisms built into the Kyoto Protocol have the potential of significantly reducing costs of limiting greenhouse gases. But if trading proceeds on a bilateral project-by-project basis rather than on a frictionless market, the total cost saving potential of trading is unclear.

EPA HAS DENIED A 1999 PETItion from environmental groups asking the agency to regulate carbon dioxide from motor vehicles under the Clean Air Act. The agency provides two primary reasons for its Aug. 28 decision: The Clean Air Act does not give EPA authority to regulate CO 2 for climate-change purposes, and setting up emissions standards for motor ...

Geochimica et Cosmochimica Acta, 1995
Abstract In many geologic environments, dominantly aqueous solutions contain low concentrations of CO2. At ambient temperature, the typical phase assemblage in fluid inclusions which trap these solutions, consists of a CO2-rich vapor (where PrmCO2 ≈ Pinternal and an aqueous phase containing dissolved salts and CO2.

C02 Recovery by way of pH Swing [PDF]
A demand for the reduction in GHG emissions from the worldwide community has seen the energy industry pressured to address its contribution to this dilemma. In recent decades there has been a push toward research into technologies that would provide energy at an affordable price while keeping with GHG emission standards, which are rising as fast ...

On Modelling the Effects of C02 on Climate
1986The sensitivity of the Meteorological Office’s 5-layer atmospheric general circulation model to enhanced atmospheric C02 concentrations with both a uniform and a latitudinally varying increase in sea surface temperatures is assessed. The changes in atmospheric temperatures depend on the sea surface temperature increases imposed, but the geographical ...
