As a zero-emission process,the acid gas injection is an alternative method for sulfur recovery and can also dispose of acid gases in a feasible,cost-effective and environmental-friendly way.In view of this,this paper first analyzes the state of the art of this process and according to case histories,makes a comparative analysis between acid injection and sulfur recovery in terms of economy,technology and environmental protection.The disposing cost of the unwanted sulfur in the acid gas injection will be US$1270 per ton;that in the sulfur recovery will be US$1400 per ton,and its cumulative cost will be more than US$1779 per ton if taking into account CO2 emission,sulfur sales,etc.Then,based on the analysis of the application need and condition of the acid gas injection,its application prospects in China are presented herein and it is also pointed out that it will be a better alternative choice in the following cases:(1) when gas quality started to change in those mature gas fields,the sulfur recovery units could not meet the need of production and need to be altered;(2) when a newly developed gas field is in a remote area or the H2S content is rather low in a gas field,the sulfur recovery is not cost-effective or the involved technologies are helpless;(3) when the component of natural gas is unstable in some newly developed gas fields,the sulfur recovery has to challenge a high cost and a high risk;(4) when the associated gas in some carbonate gas fields contains a sharply fluctuated content of H2S,it is difficult for producers to decide upon the choice of sulfur recovery process;(5) when there is a small volume of associated gas although with a high content of H2S in those dense oil fields,developed by fire flood or steam assisted gravity drainage,the sulfur recovery is never cost-effective;and(6) when the EOR measure is adopted by CO2 injection in those low-permeability oil fields.
