Run by Dongying Petroleum Technology Co., Ltd. is engaged depressant, diesel PPD, crude oil demulsifiers, corrosion inhibitors, oil additives, and other services, we are in front of the site to introduce diesel PPD had knowledge of, and now we talk about diesel PPD filling in the refinery.
一、Fill preparation：
As the winter the product viscosity, pasty, it must prepare a special filling equipment and processes.
Equipment :10-20 cubic need a tank, a steam room heated by a heating (6-10 barrel can be heated to a subject specialist conservatory can be omitted), a metering pump (range based on increase the amount of choice). Need process: low pressure steam heating process (through to the bottom of the heating room, blowing up), wind stirring processes (wind instrument through to the lower tank, diagonally, automatic form swirl), dosing process (plus point should be selected after drug diesel hydrogenation offloading pump inlet oil temperature is appropriate at 40-60 ℃).
二、Fill Precautions
1、Before filling diesel production should be calculated according to the dosage per unit time (the amount calculated in accordance with 1000ppm filling is 1,000 tons of diesel plus diesel PPD 1 ton).
2、Diesel fuel into the tank 10-15 times the amount of depressant dosage unit diesel (oil is appropriate at 40-60 ℃), open wind stirring.
3、The diesel PPD heating in the heating room to good liquidity, such as tanks and pumps, and then adjusted the metering pump range, stirring metering injection diesel pipeline (such as static mixer is better pipeline）。
4、Until then configure all run under a jar, the whole process non-mixed water。
For the above describes you understand it? If you have not understand, please call, we will fully introduce you, oh, we have a higher quality of workers, modern enterprise management mode, we welcome you to visit, business negotiations, let us join hands in creating a better future.
