WebAtmospheric tower bottoms are injected into the vacuum tower under a pressure at about 1/20th of atmospheric pressure (typically 25 to 40 mmHg or lower). Under these low … WebAtmospheric bottoms. Also known as: atmospheric resid, atmospheric residue, reduced crude, long residue, atmospheric reduced crude, topped crude. Atmospheric bottoms is the heaviest of the distillation cuts out of the atmospheric distillation tower. It consists of all of the components of crude oil that have boiling points above about 650F (343C).

WebRefinery configurations vary, but US refineries are undeniably some of the world’s most sophisticated. ... Cracking is a highly controlled process, so cracking units exist … The first commercial use of catalytic cracking occurred in 1915 when Almer M. McAfee of Gulf Refining Company developed a batch process using aluminium chloride (a Friedel–Crafts catalyst known since 1877) to catalytically crack heavy petroleum oils. However, the prohibitive cost of the catalyst prevented the widespread use of McAfee's process at that time. In 1922, a French mechanical engineer named Eugene Jules Houdry and a French pharmacist na… kate atheist in a foxhole youtube
