Description

A kind of ship tail gas denitration integrated device
Technical field
The present invention relates to ship tail gas process fields, it particularly relates to which a kind of ship tail gas desulfurization and denitrification integral fills It sets.
Background technique
According to MARPOL requirements of convention, in the Baltic Sea, the North Sea, in North America and the U.S., emission control area, the Caribbean, The sulfur content of marine fuel oil must not exceed 0.1% after on January 1st, 2015;After the year two thousand twenty January 1, except discharge control The maximum sulfur of other global sea area bunker oils other than area processed must not exceed 0.5%.
Currently, the effective measures of reply sulphur emissions limitation mainly have following three kinds of methods in the industry:
First is that using low-sulfur oil.It is less to ship change using low-sulfur oil, it is presently the most simple counter-measure.But Since the price of low-sulfur oil is basically stable at one times or so of heavy oil, will be caused to shipowner using expensive low-sulfur oil heavy Fuel cost burden.In addition, using heavy oil to for a long time or all using low-sulfur from low-speed diesel engine (product library wants to buy supply) Oil also needs to be transformed engine (product library wants to buy supply) related system.And since low-sulfur oil with host (ask by product library Purchase supply) there are biggish differences in physical property for the heavy oil that uses, and it be easy to cause fuel oil leakage dangerous and aggravates host Abrasion, will cause adverse effect to safety of ship operation.
Second is that using LNG fuel instead fuel oil.But equipment and corollary system are expensive, and shipbuilding cost is estimated need to be increased greatly About 30,000,000 dollars, and safety always exists dispute.Meanwhile filling facility in harbour is also universal not perfect in world wide.It adopts Use natural gas as fuels and energy, other than cost of investment is excessive, as a kind of inflammable and explosive hazardous gas, when LNG with In the presence of gaseous form, it must be conveyed in the pipeline of double wall.Annular space between the pipeline of double wall need by inerting or Person divulges information (product library wants to buy supply), and whether real-time monitoring (product library wants to buy supply) leaks.The density of LNG is heavy less than peculiar to vessel The half of oil, much bigger than fuel oil tank of the volume of LNG fuel compartment, if having the fuel tank of sufficient space arrangement bulky It is problem in need of consideration.And LNG is also faced with the difficulties such as endurance deficiency as foreign-going ship (position comment news) fuel Topic.
Third is that installing ship desulphurization denitration equipment additional.In this way, shipowner is not necessarily to carry out engine and oil supply system Transformation, can continue to use and the matched cheap heavy oil of host performance.It avoids because of the replacement various ships of low-sulfur oil bring Operation risk, and to do the huge improvement cost to be born of fuel using natural gas, while can be saved for shipowner a large amount of Fuel cost.If ship whole year traveling in " area Liu Kongpai ", 1 year or so i.e. recoverable cost, and safe and reliable nothing is looked back Sorrow.
Compared to first two solution, the third solution is said with respect to two to be easier to solve, it is therefore desirable to a kind of The reliable ship desulphurization denitration equipment of safety, the problem of can be effectively solved the desulphurization of ship and arrange nitre.
In addition, the dedusting for tail gas, is usually adsorbed using charcoal or coke, for abundant adsorbing nitride or vulcanization Object needs to provide enough charcoals or coke, but this also leads to the increase of cost, therefore also wishes to reduce charcoal or coke It uses.
