Abstract
The present invention relates to liquefied gas purification. During the dry desulfurizing and declorinating process of liquefied gas, liquefied gas is fed into the desulfurizing and declorinating tank from its top and made to pass through the first ceramic ball layer, desulfurizing and declorinating agent and the second ceramic ball layer successively before discharging from the bottom of the desulfurizing and declorinating tank. The dry desulfurizing and declorinating apparatus consists of desulfurizing and declorinating tank, the first ceramic ball layer in the upper part, the second ceramic ball layer in the lower part, desulfurizing and declorinating agent in the middle part.
Description
One, technical field
The present invention is a kind of technology that liquefied gas purifies in petrochemical complex, especially a kind of technology to dry liquefied gas desulfurizing and denitrifying.
Two, background technology
Liquefied gas as one of desulfurizer product, is not more than 343mg/m except total sulfur content in its quality index
3Comprise that also the copper corruption is not higher than 1 grade outward.The reason that causes the corruption of liquefied gas copper to exceed standard mainly contains: total sulfur, hydrogen sulfide, chloride ion content is high causes, the corruption problem that exceeds standard at liquefied gas copper, and the domestic method of generally taking has at present: (1) improves the sweetening power of desulfuration of liquefied gas equipment; (2) set up the alkali cleaning flow process, liquefied gas is passed through alkali lye; (3) utilize adsorbents adsorb.State method for above-mentioned three, method (1) is owing to be by optimizing the device operation, or technological transformation carries out, and the influence factor of optimizing the device operation is a lot, be difficult to keep the continous-stable of quality product, and the fund input of device technique transformation is difficult to more greatly finish for the moment; Method (2) relates to environmental issue because of the processing of waste lye, and not only salkali waste is difficult to handle, and effluent charge are higher; Method (3) is then attended to one thing and lose sight of another, and organosulfur, hydrogen sulfide and chlorion in the liquefied gas are removed simultaneously.
Three, technology contents
1, goal of the invention:
Purpose of the present invention just provides that a kind of operating procedure is simple, constant product quality, no discharging of waste liquid, the method for the dry liquefied gas desulfurizing and denitrifying that the desulfurization dechlorination efficiency is high and device.
2, technical scheme:
The method of dry liquefied gas desulfurizing and denitrifying of the present invention is that liquefied gas is imported in the jar from the top of desulfurization dechlorination jar, liquefied gas passes through the desulfurization dechlorinating agent again through the first road porcelain ball earlier, then through the second road porcelain ball, last liquefied gas is from the bottom output of desulfurization dechlorination jar, the desulfurization dechlorinating agent is " NC-L " desulfurization dechlorinating agent, and the first road porcelain ball and the second road porcelain ball are mixed by two kinds of porcelain balls respectively and form.
The device of dry liquefied gas desulfurizing and denitrifying of the present invention is made up of desulfurization dechlorination jar, the first road porcelain ball, the second road porcelain ball, desulfurization dechlorinating agent, the inlet mouth of this device is located at the top of desulfurization dechlorination jar, the air outlet is located at the bottom that jar is taken off in desulfurization, the first road porcelain ball is positioned at the top of desulfurization dechlorination jar, the second road porcelain ball is positioned at the bottom of desulfurization dechlorination jar, the desulfurization dechlorinating agent is positioned at the middle part of desulfurization dechlorination jar, and it is that 6 millimeters porcelain ball mixes to diameter that the first road porcelain ball and the second road porcelain ball are 19 millimeters by diameter.
Working process of the present invention is: from desulfurization unit or the next liquefied gas of basin, under the pressure and temperature of himself, by pipeline, valve, enter desulfurization dechlorination jar from top, canned porcelain ball and the desulfurization dechlorinating agent of being filled with of desulfurization dechlorination, after desulfurization dechlorinating agent in liquefied gas and the desulfurization dechlorination jar reacts, removes wherein sulphur and chlorine, come out directly to send outside through pipeline valve from desulfurization dechlorination pot bottom.
3, technique effect:
This invention has than prior art: (1) is less demanding to sulphur in the feeding liquid gasification, cl content, and use range is wide; (2) technology is simple, and is simple to operation, do not have the power of increasing; (3) constant product quality, the corruption of liquefied gas product copper is stabilized in 1 grade; (4) no discharging of waste liquid, non-environmental-pollution.
Four, description of drawings
