For instance, with a KBR Dense-Based Catalyst Cooler, you can control the regenerator bed temperature by adjusting the catalyst circulation rate using the TIC very carefully. There are two other primary ways to do this: reduce the feed temperature or reduce the CO2-to-CO ratio for units operating in partial-burn.

In the present study, detailed microstructure of the crack-tip region of a failed tube was examined using SEM, TEM and EBSD to clarify the relaxation crack mechanism.The second part of the question has to do with how you pick the regenerator temperature or how you pick your cat cooler duty. Details of the microstructural findings and a proposed mechanism of stress relief cracking will be discussed. To quote the great Bruce Lee again, " The key to immortality is first living a life worth remembering.

Welcome back, my most thirsty readers, and let's get going with another cocktail paired with useless information. Throw that in the blender with some ice, and it's said to bring out the drinker's "power," in a very biblical sense, if you know what I mean. The TP304H aeration system failed after three years in-service and the TP347H aeration system after six months in-service.Analysis of the most recent and a past failure determined the metallurgical and mechanical degradation mechanism(s) that led to these failures. While thinking about wild octopus tentacles in relation to wasted talent, my mind went to so many different examples. Until the telescope tube and the optics it houses reach a temperature close to that of the surrounding environment, it will not give the best images. This fast and zero backlash stepper motor has the required torque to focus of your SCT telescope with great precision.

During winter in temperate climates, well, you need some very good cooling indeed to get to ambient and stay there. I tend to keep as much of the ice pack directly over the primary mirror end thinking it has the most mass and would respond best to the direct cooling. A piece of filter material will go over the fan to filter out any particulates, however I'm having a serious problem.This paper explores the various degradation mechanisms experienced by a refinery’s RFCC catalyst cooler aeration piping system. Trying to concentrate the airflow from a larger axial fan into a tiny tube will only result in a minuscule amount of airflow. So I wanted to try my hand at creating a CAT cooler from a large PC case fan and various PVC couplings (pictures below). Designed for the durable and rigorous needs of the job site, this cooler will take the abuse of the construction industry. The most common approach for full-burn cat cooler operations we have experience with is to allow the heat removal duty be an operating variable at a cat circulation limit and/or an air blower limit.
