Abstract
The diesel oil condensation point improver can lower the condensation point of diesel oil greatly. It is prepared by using naphthenic acid, acetic acid and triethanolamine in the weight ratio of 1 to 2-4 to 0.2-0.5 as material and through stirring to mix at normal temperature. It can lower the condensation point of 0# diesel oil by over 20 deg.c, that is, make 0# diesel oil improved into -10#, -20# and -35# diesel oil.
Description
The present invention relates to a kind of diesel flow improver, particularly relate to a kind of reduction diesel oil condensation point improver.
At present, the diesel pour inhibitor of domestic production has T (803) pour point depressant of Lanzhou oil-refining chemical head factory additive factory production, the T-1805 diesel pour inhibitor that No.2 Petroleum Factory, Fushun Petro-chemical Corp produces, and all makes diesel oil reduce 5-10 ℃ of condensation point.The T-1804 diesel flow improver that Beijing Organic Chemical Plant produces is an ethylene-vinyl acetate copolymer, and diesel oil can reduce about 10 ℃ of condensation points.Be considered to the most effective a kind of diesel flow improver, in-No. 10 ,-No. 20 ,-No. 35 diesel oil of homemade various crude oil processing, be extensive use of.Abroad, the PARADYNE-25 of Exxon Neftegas Limited, ECA-5920 also make diesel oil reduce about 10 ℃ of condensation points.At present, the diesel flow improver of development and production both at home and abroad, it is all less to reduce the condensation point of diesel oil amplitude.
The purpose of this invention is to provide a kind of diesel oil condensation point improver that can reduce No. 0 condensation point of diesel oil by a relatively large margin, make No. 0 diesel oil be improved to diesel oil-No. 10 ,-No. 20 ,-No. 35.
The object of the present invention is achieved like this: diesel oil condensation point improver is to be raw material with naphthenic acid, acetic acid, trolamine, at normal temperatures, makes through stirring thorough mixing.Naphthenic acid: acetic acid: trolamine=1: 2-4: 0.2-0.5 (weight).This agent is made in No. 0 diesel oil of mother liquor interpolation.
The mother liquor preparation is that diesel oil condensation point improver is added in the kerosene, is made under heating.Diesel oil condensation point improver: kerosene=1: 15-20 (weight ratio), Heating temperature 50-60 ℃.
The diesel oil condensation point improver that adds 0.05-0.10% in No. 0 diesel oil is modulated into diesel oil-No. 10 ,-No. 20 ,-No. 35.
Diesel oil condensation point improver provided by the invention is improved to the pour point depressant of-No. 10 ,-No. 20 ,-No. 35 diesel oil mainly as No. 0 diesel oil.With No. 0 diesel oil and add agent diesel oil for No. 0 and send the check of Tianjin quality monitoring testing station, send out (1997) No. 82 documentation requirements (Tianjin) quality supervision (008) number survey report of reading according to GB252-94 " solar oil " standard and State Bureau of Technical Supervision's prison and show: No. 0 diesel oil adds adding agent diesel oil and making condensation point descend below 20 ℃ of thousandth condensation point improver.The pour point depression effect is better than the T-1804 diesel flow improver of Beijing Organic Chemical Plant and PARADYNE-25, the ECA-5920 of Exxon Neftegas Limited.
This diesel oil condensation point improver has carried out industrial amplification test,-No. 10 ,-No. 20 ,-No. 35 diesel oil that in No. 0 diesel oil, add the diesel oil condensation point improver furnishing, through refinery quality test section assay, its every index meets national standard fully, proves its use properties and do not add agent diesel oil suitable through cold start-up, cold district road test.This condensation point improver raw material is easy to get, and makes simply reliable in quality.20,000 yuan/ton of costs.It is big to add agent-No. 20 ,-No. 35 diesel oil and No. 0 diesel oil price differential, and economic benefit improves.
Below in conjunction with embodiment, the invention will be further described.
To make 1000 kilograms of diesel oil condensation point improvers is example, with 286 kilograms of the naphthenic acid of 584 kilograms of the acetic acid of content 98%, acidity 240, acid number 180, in adding equipment, under stirring at normal temperature, make respectively by thorough mixing for 167 kilograms of three kinds of raw materials of the trolamine of content 85%.The diesel oil condensation point improver outward appearance: light yellow liquid, density (20 ℃) 0.85, condensation point are less than 8 ℃.Kinematic viscosity 70mm
2s
-1Get 1 kilogram of this diesel oil condensation point improver, add 20 kilograms of kerosene, heat 50 ℃, under agitation, add 1000 kilograms of No. 0 diesel oil, thorough mixing is promptly made diesel oil-No. 20.This diesel oil and No. 0 diesel oil that adds 1/1000 kilogram of diesel oil condensation point improver send the Tianjin quality monitoring testing station the 41st station survey report: No. 0 condensation point of diesel oil-3 ℃, add agent diesel oil-25 and ℃ do not coagulate.
Claims (2)
1, a kind of diesel oil condensation point improver is characterized in that: diesel oil condensation point improver is to be raw material with naphthenic acid, acetic acid, trolamine, at normal temperatures, makes naphthenic acid through stirring thorough mixing: acetic acid: trolamine=1: 2-4: 0.2-0.5 (weight).This agent is made in No. 0 diesel oil of mother liquor interpolation.
2, by the described diesel oil condensation point improver of claim 1, it is characterized in that: the mother liquor preparation is that diesel oil condensation point improver is added in the kerosene, is made under heating.Diesel oil condensation point improver: kerosene=1: 15-20 (weight ratio), Heating temperature 50-60 ℃.
