Marine fuel and offshore production platform boiler oil after combustion, can be generated containing oxysulfide (hereinafter
SOX), nitrogen oxides (hereinafter NOX) etc. substances, these substances can be discharged into air in the form of exhaust gas.And SOXIn
SO2, acid rain can be formed in an atmosphere, and harm is generated to environment and the mankind.It administers sulfur dioxide and has become global common recognition, it is international
International Maritime Organization (IMO) (IMO)《《73/78 anti-pollution convention》(MARPOL pacts) supplemental provisions VI requirements：I.e. from 2012, in high sea row
The sulphur content of fuel oil of the foreign-going ship made has to be lower than 3.5% (m/m), and 0.5% (m/m) is would fall to the year two thousand twenty, and this
Scheme completes feasibility and examines and will be carried out earlier than 2018.
Offshore production platform boiler oil is using the crude oil just exploited, and many sulfur materials are contained in the inside, at present state
Interior all offshore production platforms are all without applying any desulphurization plant, currently without a set of technology maturation and suitable for offshore oil production
The desulfurization program and product of platform, how to handle the sulfur dioxide of its generation is current problem to be solved.
Existing flue gas desulfunzation device is sprayed into lye in the form of spraying in exhaust gas using wet desulphurization is sprayed, with
Exhaust gas mixes, through chemically reacting SO in exhaust gasX、NOXIt captures and enters in liquid phase, achieve the purpose that purification.But exhaust gas is generally high
Temperature, lye spray into meeting partial gasification in exhaust gas, are discharged together with exhaust gas, it is possible to cause secondary pollution.And spray process can generate
A large amount of waste water containing a large amount of flue dust, oil, heavy metal etc. in waste water, needs to increase complicated waste water treatment system, increases energy
Consumption increases cost, and bulky spray tower systems are not advantageously mounted on production platform.
In currently used equipment, there are one liquid in-out mouths, and liquid is not completely filled in many ceramic-film tubes or is not had
There is liquid, cause desulfuration efficiency low and the waste to ceramic-film tube.Secondly it is influenced, is filled by temperature in practical applications
Deformation can be generated by putting, and lead to ceramic tube fracture or ceramic tube and outer loop pipeline Joint failure.Or in transportational process
Jolting or shaking leads to failure of apparatus.In addition, ceramic membrane is impermeable layer used by the device, membrane aperture size is on a 10nm left sides
The right side, in sweetening process, the easy fouling of ceramic vessel wall blocks ceramic membrane nano-pore, and desulfuration efficiency is caused to reduce and is even lost completely
