Embodiment 1

[0023] This embodiment provides a figure 1 The movable integrated treatment device for acid liquid and acid gas shown includes a skid base 13 on which a reactor 4 is installed, and the top of the reactor 4 is provided with a lye injection port 5 and a defoamer injection port 6 , the lye injection port 5 is connected to the alkali injection pump 9 through the pipeline, the defoamer injection port 6 is connected to the defoamer injection pump 10 through the pipeline, and the alkali injection pump 9 and the defoamer injection pump 10 are all installed on the skid base 13 ;

[0024] The inlet end of the reactor 4 is connected with the inlet pipeline, and the mouth of the inlet pipeline is the device inlet 8, and the inlet sampling port 7 is opened near the device inlet 8 on the inlet pipeline, and the outlet end of the reactor 4 is connected with the outlet pipeline, and the outlet pipeline The mouth of the pipe is the device outlet 1, and the outlet sampling port 2 is opened on ...

Embodiment 2

[0029] On the basis of Embodiment 1, it also includes an integrated control cabinet 11 and a tool storage room 12 installed on the skid base 13, and the alkali injection pump 9, the defoamer injection pump 10 and the tool storage room 12 are sequentially along the length direction of the skid base 13 Arranged, the integrated control cabinet 11 is located between the defoamer injection pump 10 and the tool storage room 12 and is arranged close to the long side of the skid seat 13.

[0030] The specific arrangement is as figure 1 , this arrangement makes full use of the space of the skid base 13, and the whole structure is an integrated design. At the same time, according to the actual needs of the site, a lighting system, etc. can be installed on the skid base 13, and can be controlled through the integrated control cabinet 11.

Embodiment 3

[0032] On the basis of Example 1, such as figure 2 As shown, the reactor 4 is divided into a pipeline mixing part 402 and a slow-release part 401, the slow-release part 401 is connected with the inlet pipeline, and the inner cavity of the slow-release part 401 is evenly spaced along the length direction with a plurality of anti-erosion partitions 14. The pipeline mixing part 402 is in communication with the outlet pipeline. The inner cavity of the pipeline mixing part 402 is provided with double helical blades 3 along the length direction.

[0033] The device reactor is divided into a slow release part 401 and a pipeline mixing part 402. The diameter of the slow release part 401 becomes larger to reduce the flow rate, and the anti-erosion partition 14 is used to change the flow direction of the liquid, so that the flowback liquid and the defoamer are fully mixed and reacted; The pipeline mixing part 402 uses double helical blades 3 to fully mix and react the acid liquid, acid...

Abstract

The invention provides a movable acid liquid and acid gas integration treatment device and a treatment process of the treatment device. The treatment device comprises a prizing base, wherein a reactor is mounted on the prizing base; an alkaline liquid injection port and a defoaming agent injection port are formed at the top of the reactor; an inlet sampling port is formed in an inlet pipeline of the reactor; and an outlet sampling port is formed in an outlet pipeline of the reactor. Separated treatment after gas-liquid separation is not required; acidification flowback liquid discharged by a gas well mouth is subjected to throttling and pressure reduction, directly enters the reactor, is obstructed and slowly released by a scouring protection partition plate, and reacts with a defoaming agent to defoam; acid liquid and acid gas are sufficiently mixed with an NaOH solution with the mass concentration of 10-30% at a mixer inlet, and subjected to a neutralization reaction, so that a pH (potential of hydrogen) value of the discharged liquid is 6-8, HCl content in the discharged gas is less than 1.9mg / m<3>, and HF content is less than 100mg / m<3>; gas field acidification flowback liquid gas and liquid integration treatment is realized; two-phase separation is not required; on-site pipeline connection is quick and convenient; the device is simple to operate; the treatment is high-efficiency and quick; the cost is low; and pollution of acidification flowback residual acid and acid gas to a human body and an environment is eliminated.

Description

technical field [0001] The invention belongs to the technical field of reservoir transformation and clean production in the oil and gas industry, and in particular relates to a movable integrated treatment device for acid liquid and acid gas and a treatment process thereof. Background technique [0002] In the process of gas field production, acid fracturing is one of the main measures to increase and stabilize production. The acid liquid system is generally obtained by mixing the main agent and various additives. The main agent includes hydrochloric acid, hydrofluoric acid, etc., and the additives include corrosion inhibitor, bactericidal Agents, retarders, clay stabilizers, surfactants, etc. After the acidification operation, a large amount of residual acid and acid gas will be discharged, which has the characteristics of strong acidity, strong corrosion, pungent smell, high iron content, and high salinity. It will cause huge health and safety hazards to the local environm...
