Novel skid-mounted equipment for removing hydrogen sulfide in natural gas

Abstract

The invention provides novel skid-mounted equipment for removing hydrogen sulfide in natural gas. The equipment comprises a coalescing separator used for separating droplets and solids which are 5mu m or over, a heater used for realizing complex heating on natural gas to guarantee that the gas temperature is higher than dew point temperatures of water and hydrocarbon, a membrane separator used for crudely separating hydrogen sulfide in natural gas, a torch used for conducting vent combustion or intensive treatment on high-sulfur-content gas, a desulfurization tank used for re-adsorbing and removing remained small amount of hydrogen sulfide in the natural gas, a flowmeter used for monitoring throughput of the treated natural gas and a purified gas pipe network used for delivering standard natural gas, wherein a differential pressure gauge is arranged on the coalescing separator; and a dust filter is arranged at the natural gas outlet in the bottom of the desulfurization tank. The novel skid-mounted equipment has the advantages of highly integrated skid mounting, simplified process, convenience in transportation and removal, operation cost reduction and monitoring function availability.

Description

technical field [0001] The invention belongs to the technical field of natural gas purification treatment equipment, and in particular relates to a novel skid-mounted equipment for removing hydrogen sulfide in natural gas. Background technique [0002] Natural gas is a clean, environmentally friendly and safe energy source. With the increasing use of natural gas, people are more concerned about hydrogen sulfide in natural gas. Sulfur-containing natural gas must undergo a series of desulfurization and dehydration purification before it can enter the gas pipeline network for use. In the desulfurization device of the prior art, because the raw natural gas contains a lot of impurities, usually multiple sections or multiple desulfurization towers are connected in parallel or in series to meet the requirements of sulfur content after desulfurization, the structure is complex, the floor area is large, and it is inconvenient to transport and relocate. Higher operating costs. Cont...
