International Journal of Oil, Gas and Coal Technology

Abstract: Acid gas removal is an important part of natural gas processing which is designed based on the type and concentration of impurities and the final specifications for the outlet gas. The typical process for removing acid gases involves their absorption from natural gas into a regenerative solvent.

The Engineer Who Discovered Global Warming - ASME

Apr 29, 2020 · The specific contribution of carbon dioxide to this warming effect was quickly noticed. In 1856, the 37-year-old American physicist Eunice Newton Foote discovered that a glass bottle of CO 2 placed in the sun rose to a higher temperature than a bottle of air. As a woman she was not allowed to present her research, so her paper, Circumstances Affecting the Heat of the Suns Rays, was

Ventilation (architecture) - Wikipedia

Combustion (e.g., fireplace, gas heater, candle, oil lamp, etc.) consumes oxygen while producing carbon dioxide and other unhealthy gases and smoke, requiring ventilation air. An open chimney promotes infiltration (i.e. natural ventilation) because of the negative pressure change induced by the buoyant, warmer air leaving through the chimney.

Digital Mass Flow Meters & Flow Controllers by Sierra

Unaffected by upstream gas temperature and pressure fluctuations like other differential pressure devices, digital gas mass flow controllers and meters provide the most reliable, repeatable, and accurate gas mass flow for a variety of gases, including natural gas, air, nitrogen, and argon.

Gasifiers - an overview | ScienceDirect Topics

Gasifiers are classified mainly on the basis of their gassolid contacting mode and gasifying medium. Based on the gassolid contacting mode, gasifiers are broadly divided into three principal types (Table 6.1): (1) fixed or moving bed, (2) fluidized bed, and (3) entrained flow.Each is further subdivided into specific types as shown in Figure 6.1.

May 12, 2021 · 1821 - First Natural Gas Well in US Is Drilled "In 1821, the first well specifically intended to obtain natural gas was dug in Fredonia, New York, by William Hart. After noticing gas bubbles rising to the surface of a creek, Hart dug a 27 foot well to try and obtain a larger flow of gas to the surface.

Cost of electricity by source - Wikipedia

Utility-scale solar power [could in 2011] be delivered in California at prices well below $100/MWh ($0.10/kWh) less than most other peak generators, even those running on low-cost natural gas. Lower solar module costs also stimulate demand from consumer markets where the cost of solar compares very favourably to retail electric rates.

Agricultural Anaerobic Digesters: Design and Operation

Dec 01, 2016 · The manufacturer's rating for boilers indicated a boiler efficiency of 0. 7 with LP gas and 0.78 with natural gas. The value of 0.58 was used in calculating the needed boiler capacity due to intermittent and low-load operation. A boiler with a rated input value of 66,000 Btu/hr (19.5 kW) was selected for the Penn State digester installation.
