Problems solved by technology

The sulfur capacity obtained by the current standard evaluation method cannot represent the real situation on site, resulting in a mismatch between the selected desulfurizer and the natural gas at the production site, which in turn leads to the inability of the desulfurizer to effectively remove hydrogen sulfide in natural gas, resulting in excessive hydrogen sulfide content in natural gas. There are safety risks in exporting natural gas, which greatly reduces the development benefits of oilfields

Abstract

The invention discloses a method for testing sulfur capacity of an on-site natural gas dry desulfurizer. The method comprises the following steps of filling a filling tube with particles of the desulfurizer; vacuumizing the filling tube to negative pressure; filling the filling tube with nitrogen to positive pressure; releasing the pressure of the nitrogen in the filling tube to 0MPa; connecting an inlet pipe to a sampling port of a natural gas pipeline; making the natural gas flow through the desulfurizer; finding that hydrogen sulfide starts to emerge from a lead acetate solution tank; recording the flow parameters; and calculating the sulfur capacity of the desulfurizer. The invention modifies the existing sulfur capacity test method of the desulfurizer, and achieves the test effect onthe sulfur capacity in the filling state of the on-site gas source and the on-site desulfurizer.

Description

technical field [0001] The invention relates to the field of oil field natural gas desulfurization, in particular to a method for testing the sulfur capacity of an on-site natural gas dry desulfurizer. Background technique [0002] Hydrogen sulfide (H2S) is a by-product of oilfield development and production. Due to its strong corrosiveness and high toxicity, H2S has become an important target for risk management and control of oilfield production process. In oilfield surface treatment systems, hydrogen sulfide mainly exists in natural gas. Excessive hydrogen sulfide content in natural gas not only poses a serious threat to safe production and residential gas safety, but also causes corrosion to equipment and pipelines, bringing serious safety hazards. For this reason, natural gas must be desulfurized. [0003] Compared with wet desulfurization, dry desulfurization has a wider applicable temperature range, simple process, convenient operation, and less equipment. For low ...
