Engineering Problem 3: Hazards (Energetic) CNG633 Process Control & Industrial Safety Synthesis gas, or "syngas, is a gaseous mixture of CO, Hz and several inert gases that may be produced from a variety of organic materials. A common method of producing syngas is coal gasification using a reactor known as a Lurgi gasifier. The reactions for coal gasification, assuming coal is pure carbon, are shown below: 1) 3C) + O2 + H2O) Hill + 3COO) 29 2) CO) + H2O) CO240 + H2 A Lurgi gasifier, the typical vessel for coal gasification, has the following operating properties: 930C 1.4 MPa Batch feed of 1.50 te of solid coal (carbon) Water is fed at a 4x molar excess for Reaction 1 The reactions occur in series (1 occurs before 2) Reaction 1 proceeds to 87% completion (molar basis) Reaction 2 proceeds to 64% completion (molar basis) a) List three (3) energetic hazards associated with the Lurgi gasifier. b) Determine the LEL (in v/v%) of the product mixture.
