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
The invention belongs to the purification apparatus technical field of Sweet natural gas, especially relate to a kind of novel skid-mounted device removing hydrogen sulfide in natural gas.
Background technology
Sweet natural gas is the energy of cleaning, environmental protection, safety, along with Sweet natural gas is by increasingly extensive use, people is more paid close attention to the hydrogen sulfide in Sweet natural gas.The Sweet natural gas of sulfur-bearing just must can enter gas line network and use after desulfurization, a series of purification of dewatering.Due to many containing mixing in raw natural gas gas in the desulfurizer of prior art, after usually adopting more piece or the parallel connection of multiple thionizer or series connection just can reach desulfurization, sulphur content reaches requirement, complex structure, and greatly, be inconvenient to transport resettlement, running cost is higher for floor space.
Summary of the invention
The problem to be solved in the present invention is to provide the highly integrated skid of one, and process simplification, conveniently transports resettlement, reduces running cost, possesses the novel skid-mounted device removing hydrogen sulfide in natural gas of monitoring function simultaneously.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of novel skid-mounted device removing hydrogen sulfide in natural gas, comprise and be separated the drop of more than 5um and the coalescing separator of solid, realize carrying out re-heat intensification to Sweet natural gas, ensure that gas temperature is higher than water, the well heater of hydrocarbon dew point temperature, hydrogen sulfide in Sweet natural gas is carried out the membrane separation apparatus of roughing out, realize the torch that high sulfur-containing gas emptying is burnt or focused on, realize the digester to a small amount of hydrogen sulfide remaining in Sweet natural gas adsorbing and removing again, realize the under meter that the Sweet natural gas throughput after to process is monitored, to the purified gas pipe network that standard compliant Sweet natural gas is carried.
Described coalescing separator is provided with differential manometer.
Bottom described digester, gas outlet is provided with dust filter unit.
Owing to adopting technique scheme, Sweet natural gas enters coalescing separator, separates drop and the solid of more than 5um, can not there is blocking pipe valve instrument when ensureing that equipment runs.Coalescing filter arranges differential manometer, needs when pressure reduction is greater than 50kpa to change Coalescence filter core, ensure the separating effect of Coalescence filter core.The Sweet natural gas removing moisture enters well heater again, uses well heater to carry out re-heat intensification to Sweet natural gas, ensures that gas temperature is higher than water, hydrocarbon dew point temperature 5 ~ 10 DEG C.Sweet natural gas after heating enters membrane separation apparatus, and by the centrifugation of organic permeable membrane, the hydrogen sulfide of more than 90% is all penetrated into infiltration gas and arranges the torch entering emptying burning or focus on outward.Sweet natural gas containing the hydrogen sulfide of the 100 ~ 1000ppm that has an appointment enters digester as the tail gas of membrane separation apparatus, by a small amount of hydrogen sulfide in the sweetening agent that loads in digester again adsorbed gas, ensures that the hydrogen sulfide in natural gas content exported is less than 20ppm.Bottom digester, gas outlet filters out the desulfurizer powder that may carry through dust filter unit, enters under meter metering, and control desulfurization sledge pressure through Self-operated pressure control valve, Sweet natural gas enters purified gas pipe network or local use afterwards.
The invention has the beneficial effects as follows: highly integrated skid, process simplification, conveniently transports resettlement, reduces running cost, possesses the advantage of monitoring function simultaneously.
