Problems solved by technology

The volume of the mixed oil tank is related to the amount of mixed oil. The greater the amount of mixed oil, the larger the volume of the built oil mixed tank and the greater the construction cost of the pipeline.

Embodiment Construction

[0013] Isolator technological process of the present invention is as follows (seeing Fig. 1, Fig. 2, Fig. 3):

[0014] 1. Isolator sending system

[0015] After the current oil product exits the station through the pump station, before the subsequent oil product exits the station, the exit sequence of the separator gel must be between the two. The isolator sending system is arranged downstream of the pumping station (9) and consists of an isolator sender (12) and valves (10, 11, 13). As shown in Figure 2, the isolator transmitter is composed of a silo (14) with a bottom valve and a Venturi ejector tube connected thereto (Figure (17). When sending, the valves (10, 13) are opened first, and then the valves are closed. (11), open the feed bin bottom valve (16). The Venturi tube has an ejection effect at the throat, sucking the configured gel separator into the pipeline. The dosage of the gel separator is 5 to 15 times the pipe diameter. After sending, close feed bin bottom va...

Abstract

The present invention belongs to oil-gas storaging and transporting engineering field, relating to a blending shielding system and using method. The blending shielding system includes an isolated body transmitting system, a recovery system and a pump station system fpr connecting the above pipelines and set with valve of travel beyond destination station. The isolated body sending system includes an isolated body transmitter, a valve and an isolated body. The recovery system includes an isolated body recoverer, a valve and an isolated body detector. The isolated body adopts PAM as polymer, selecting aluminium citrate as a cross linker, selecting water as solvent for preparing elastic gel, the elastic gel is semi-solid, having a certain liquidity, free deforming. The isolated body transmitter, recoverer and over-reach process of the invention has a simple structure, easy operating. The method realizes isolated body transmitting, over-reach and recovery process, reduces 77% blending quantity.

Description

technical field [0001] The invention belongs to the field of oil and gas storage and transportation engineering, and relates to a mixed oil isolation system and a use method. Background technique [0002] Sequential delivery of oil products refers to the pipeline oil transportation process that continuously transports various oil products in a certain order in a pipeline. The oil products to be transported in sequence are mainly gasoline, kerosene, diesel and other light oil products, as well as liquefied petroleum gas and heavy oil products. Oil products of different specifications or different brands among the same oil products can also be transported in batches; crude oil of different properties in different oil fields can also be transported in batches according to refining requirements. The sequential delivery of various oil products has obvious economic benefits compared with the delivery of multiple single oil product pipelines. Therefore, sequential transportation ...
