Ccr Operation Question! - Refining, Hydrocarbons, Oil, and Gas » Ccr Operation Question! - posted in Refining, Hydrocarbons, Oil, and Gas: my name is thanh, a process Engineer. I only have 6 months to operate CCR unit. Could you help me some questions: 1. How to predict Hydrogen/hydroccbon ratio by your experiences (we have H2 recycle gas flow, h2 net gas flow, and feed flow). 2. How to predict the catalyst age. thanks a lot Cheresources.com

Hydrochloric Acid » Hydrogen chloride, anhydrous appears as a colorless gas with a sharp, pungent odor. Fumes strongly in moist air. Nonflammable. Corrosive to metals and tissues … Pubchem.ncbi.nlm.nih.gov

Hydrocarbon contains 18.18% hydrogen and 81.82% carbon. One litre of this gas has the same mass as carbon dioxide. What is the molecular formula of this hydrocarbon? | Socratic » Given the percentage composition of HC as C->81.82% and H->18.18% So the ratio of number if atoms of C and H in its molecule can will be C:H=81.82/12:18.18/1 C:H=6.82:18.18 =6.82/6.82:18.18/6.82=1:2.66~~3:8 So the Empirical Formula of hydrocarbon is C_3H_8 As the mass of one litre of hydrocarbon is same as that of CO_2 The molar mass of the HC will be same as that of CO_2 i.e 44g/"mol" Now let Molecular firmula of the HC be (C_3H_8)_n Using molar mass of C and H the molar mass of the HC from its molecular formula is (3xx12+8xx1)n=44n So 44n=44=>n=1 Hence the molecular formula of HC is C_3H_8 Socratic.org
