Method and device for determining synthesis gas production technology

Abstract

The invention puts forward a method and a device for determining a synthesis gas production technology. The method for determining the synthesis gas production technology comprises the following stepsthat: after multiple pieces of coal gasification technical data, various pieces of natural gas conversion technical data, energy consumption conversion data and basic cost data are obtained, establishing a plurality of synthesis gas production simulation model which combines various coal gasification technologies with various natural gas conversion technologies; then, according to the effective air flow, the carbon hydrogen ratio and the gasifier data of the synthesis gas, determining the simulation result of each synthesis gas production simulation model and a corresponding energy consumption index and economic index; and finally, according to the two indexes, selecting an optimal synthesis gas production scheme from various scheme combinations. By use of the method and the device, the optimal technical combination scheme can be determined, a coal-natural gas raw material matching problem in the corresponding technical combination scheme is further solved, so that a corresponding chemical project quickly, integrally and systematically realizes technical economic benefit maximization in a scheme comparison and selection stage.

Description

technical field [0001] The invention belongs to the technical field of chemical engineering, and in particular relates to a method and device for determining synthesis gas production technology. Background technique [0002] Although there are coal and natural gas reserves in some resource areas at present, the utilization methods of coal and natural gas in the prior art are relatively single, that is to say, the prior art only considers the comprehensive utilization of one resource and ignores the effects of other resources. It does not take into account the complementary characteristics of different resources, which not only causes waste of resources, but also reduces economic benefits. [0003] As we all know, when applied to various gasification and conversion technologies, there will be an optimal ratio of input resources of coal and natural gas resources; in terms of coal gasification, natural gas conversion and other technologies, different gasification technologies a...
