Example Embodiment

[0018] In order to understand the technical solutions of the present invention more clearly, the present invention will be further described below with reference to specific embodiments.

[0019] A ferrous sulfide passivator of the present invention is made of the following components, and the mass ratio of each component is Tween 80 35%, citric acid 0.5%, sodium lauryl sulfate 20%, potassium permanganate 1%, secondary deionized water 43.5%.

[0020] A preparation method of a ferrous sulfide passivator, the preparation method adopts the following steps:

[0021] A measure the raw materials according to the mass percentage of Tween 80 35%, citric acid 0.5%, sodium lauryl sulfate 20%, potassium permanganate 1%, secondary deionized water 43.5%, check the mixer, add the secondary deionized water ionized water;

[0022] B. Slowly add citric acid into the mixer, turn on the mixer, record the mixing time, and the time required from the start of the mixer to the end of citri...

Abstract

The invention discloses a ferrous sulfide passivator and a preparation method thereof. The invention is characterized in thatThe ferrous sulfide passivator is prepared from the following components in percentage by mass: 30-40% of Tween 80, 0.4-0.6% of citric acid, 15-25% sodium lauryl sulfate, 1-2% of potassium permanganate and 40-50% of secondary deionized water. The invention has the following advantages: 1) the reaction speed is high, and no toxic or harmful gas is generated in the reaction process; 2) the reaction product is stable, can not be decomposed into toxic substances, can be directly discharged to a sewage treatment plant without damaing the active bacteria of the sewage treatment plant, and can not impact the sewage treatment plant; 3) the ferrous sulfide passivator is efficient and non-toxic, is safe to the human body before and after the reaction, and does not corrode the apparatus; 4) the ferrous sulfide passivator is packaged and transported in a high-concentration state, and used after being diluted, thereby being convenient, quick and low in cost; and 5) the application method is simple and convenient, does not change the technical process, and does not need to add any apparatus and additional material.

Description

technical field [0001] The invention relates to the technical field of passivating agents, in particular to a ferrous sulfide passivating agent and a preparation method thereof. Background technique [0002] With the increase in the amount of crude oil processed by refining and chemical enterprises and the increase in sulfur content, and the long-term, full-load operation of the device, the ferrous sulfide deposited inside the equipment is continuously increasing, which will bring great harm to the safety of the device during maintenance. big threat. Accidents of ferrous sulfide self-combustion damaging equipment and internal packing of equipment have occurred in various manufacturers, which has caused huge losses to the manufacturers. Contents of the invention [0003] In order to overcome above-mentioned deficiencies in the prior art, the invention provides a kind of ferrous sulfide passivator and preparation method thereof, this ferrous sulfide passivator is effici...
