·MODERN DELAYED COKING PROCESS The delayed coker is the only main process in a modern petroleum refinery that is a batch continuous process The flow through the tube furnace is continuous The feed stream is switched between two drums One drum is on line filling with coke while the other drum is being steam stripped cooled decoked pressure
·Final consumption of coal Apart from power generation coal is also used directly in high heat industrial processes notably steelmaking and in some countries is used to heat homes and buildings In non energy applications coal can be used to produce the industrial chemicals needed to make plastics and fertilizers
·1 Introduction Direct coal liquefaction is a promising approach for producing clean liquid fuels and valuable chemicals Noticeably direct coal liquefaction residue DCLR is the main by products which accounts over 30 wt% of raw coal [1] [2] [3] [4] One key problem in direct coal liquefaction process is the solid liquid separation methods of hydroliquefaction
·By contrast the increase in the addition of fluff to the coal resulted in a reduction in sulfur as shown in Fig 4 which is a direct consequence of the higher sulfur content in the coal from % for MGC coal than in the fine fluff % The values obtained indicate a clear behavioral trend for the studied conditions R 2 = The reduction in sulfur is
As discussed in Chapters 19 and 22 pyrolysis processes could be run to make gases or liquids rather than solids as the primary product Carbonization more narrowly defined refers to conversion of a starting material into carbon or a carbon rich solid Note you can select to save to either the or variations
·The blends of multiple coals with distinct properties were heated to temperature exceeding 1100 °C in coke oven in order to produce metallurgical coke [1] during which a multitude of chemical reactions took place [2] [3] [4] The evolution of coking properties was contingent upon the coal structure transformation during carbonization as previously
·The maceral composition surface oxidation and particle liberation are the factors that affect coal flotation The oxidized coal requires more collectors than the freshly ground coal The flotation process modeling and optimization of − mm coal fraction was carried out using response methodology and central composite rotatable design CCRD
The quality and cost of coke are directly affected by the proportion of different categories of coal while the coal blending in coking process is a complex one with multiple objectives and constraints In this study a multi objective simulated annealing algorithm MOSA based coal blending optimization approach in coking process is proposed The objective function which
Main differences between conventional and non recovery/heat recovery processes are shown in figure 1 In conventional process the coal charged receives the heat indirectly through the furnace walls by combustion of external gas; inside the oven positive pressure develops Gas generated in the coking process is sent to the by products plant
