Armed with knowledge and technology, we can have both; energy security and a clean environment. Read More ›
Benefits to highlight: organize the information of the refinery energy system in one model and one environment that everyone has access to. Understand the economic impact of all the decision variables and constraints, which sometimes is hidden or ignored. Allow the centralization of the responsibilities for operating the system optimally. Involvement of operators since beginning, crucial for successful implementation and amount of benefits. Robustness of the optimizer allows operations personnel Confidence. Final user’s acceptance and widespread use, for both engineers and operators.

Energy Saving and Increase Capacity in Crude Distillation Unit by Column Implementation in Vapor Stream Preflash Drum in Tabriz Oil Refinery
Vapor from flash drum to two tray below flash zone of crude tower increase 16% atmospheric gas oil (AGO) yield: For light crude, implementation preflash column, increase efficiency; Column implementation in vapor stream preflash drum increase 11% AGO yield and decrease corrosion problems in the top of the crude column; Column implementation in vapor stream preflash drum increase steam injection to crude column and decrease pressure crude tower; With increase inlet temperature preflash drum to 210℃ and column implementation in vapor stream preflash drum increase 20% capacity in crude tower; Consider implementation flash drum after atmospheric bottom stream.
Cogeneration can be an effective means of reducing energy costs and reducing overall greenhouse gas emissions. A number of technical and economic design factors must be considered in order to produce an optimal design. Read More ›
China refining capacity continues to increase, albeit at a slowdown rate, Ratio of oil import increased. Portion of sour, acidic and heavy crude supply to increase, increased crude processing depth will lead to fast increase of gasoil/residue hydrotreating capacity; Newly added refining capacity will be mainly for refined oil products, refining and chemical integration pattern might be changed. Oil products quality standards will be tightened with the enforcement of GB IV standards, saving energy and pursuing clean production will be the solution. Read More ›
Preflash column inlet temperature was Increase by increasing the heat recovery from the preheat train network, resulting in a decrease in furnace duty and an increase of throughput. Read More ›
