Embodiment Construction
[0035] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0036] 1) First, according to the ethylene production process flow, determine the type of energy medium in the power consumption part and the type of energy medium in the power delivery.
[0037] 2) as figure 1 As shown, the input and output data are determined according to the needs of this evaluation method. The calculation formulas of the comprehensive energy consumption per unit of external energy and the external energy indicators of ten thousand yuan of output value are as follows:
[0038]
[0039] Among them, m is the type of external energy. The size and symbol of the conversion coefficient are related to the destination of the external energy, which is determined by Table 1;

The invention belongs to the ethylene production energy efficiency assessment field and relates to an ethylene production efficiency dynamic assessment method considering outbound transportation energy. Dynamic analysis of comprehensive energy consumption of unit outbound transportation energy and ten thousand output value outbound transportation energy during an ethylene production process is realized. Through considering the outbound transportation energy which is output of power consumption, from a perspective of an economic value, relative effectiveness comparison of an outbound transportation energy rate is performed on real-time data through a data envelopment analysis method so that efficiency dynamic analysis considering the outbound transportation energy is realized. The method has the following advantages that through comparing the comprehensive energy consumption of the unit outbound transportation energy to the ten thousand output value outbound transportation energy, a relative ratio of an outbound transportation energy value and a product value can be acquired; whether a current energy investment is proper is analyzed and a problem that an added production value is generated because the outbound transportation energy is neglected is solved. The method in the invention can be widely used for the ethylene production energy efficiency assessment calculating field.
Description
technical field [0001] The invention relates to an energy efficiency evaluation method for ethylene production, in particular to a dynamic energy efficiency evaluation method for ethylene production considering external energy sources. Background technique [0002] Ethylene is a pillar industry of the petrochemical industry, and its output is the main indicator to measure the development level of a country's petrochemical industry. Since the 1960s, my country has been paying attention to the development of the ethylene industry. The production of ethylene has reached a considerable scale, and its output now ranks second in the world. However, there is still a big gap between my country's ethylene production technology and the international technical level. In 2006, the average comprehensive energy consumption of ethylene in my country was 709 kilograms of standard oil / ton, and the comprehensive energy consumption of ethylene at the international advanced level reached 500 k...
