Gas detector - Wikipedia

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.

Wall-to-Bed Heat Transfer in Bubbling Fluidized Bed

Apr 27, 2021 · Measurements were carried out to investigate the wall-to-bed heat transfer in a cross-flow bubbling fluidized bed under continuous solids exchange. The experiments were performed with different tube bundle heat exchangers immersed in a lab-scale gassolid fluidized bed cold flow model 0.4 m × 0.2 m in cross section. Geldart group B particles were used, and the gas velocity, the solids

Carbon capture and storage (CCS): the way forward - Energy

Pilot plant tests using an unpromoted 30 wt% K 2 CO 3 solution could only absorb between 2025% of the CO 2 from the flue gas. 248 To improve CO 2 mass transfer, K 2 CO 3 requires the addition of a promoter or catalyst. 247 The Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC) have developed and optimised the K 2 CO 3
