Regarding the selection principle of oilfield sewage treatment instrument equipment, how to do the truth can emerge out of the circle

In oilfield sewage treatment, do you know how to choose the correct flowmeter? You must know that the selection of models is based on the principle of selection, so everyone knows what to do to make the truth emerge out of the circle? Here, I hope my thoughts can help you.

Oilfield sewage treatment process medium and chemical agents have the characteristics of strong corrosiveness and complex components. This project involves hydrochloric acid, sodium hydroxide, degreaser, coagulant and coagulant aid. There are high requirements for the selection of instrumentation equipment, especially the selection of wetted materials. The selection principle is that the instrument and equipment selection are based on domestic high-quality products, which should be advanced technology, cost-effective, can meet the environment and process conditions, and have been proved to be products with mature technology in industrial applications.

(1) Temperature meter

A bimetal thermometer is used for local temperature indication, and an integrated temperature transmitter is used for remote indication of temperature detection.

(2) Pressure gauge

The pressure gauge installed at the equipment with large mechanical vibration such as the pump adopts the shock-resistant pressure gauge, and the diaphragm pressure gauge is used for the pressure measurement of corrosive media such as acid and alkali. Among them, flange diaphragm pressure transmitter is used for remote transmission indication of pressure detection, and the material of diaphragm and diaphragm is Hastelloy.

(3) Liquid level instrument

Radar liquid level gauge is used for remote indication of liquid level detection in sludge concentration tanks, sewage oil tanks, etc.; Flange liquid level transmitter is used for remote indication of liquid level detection in degreasing tanks and other water tanks; the use of tuning fork liquid level switches is used for high and low alarm interlocking of storage tank liquid level to stop the pump, and the liquid level of chemical storage pool and dosing pool. Magnetic float level gauge is selected for local indication; guided wave radar level transmitter is selected for remote indication of liquid level in sewage recovery pool and acid-base wastewater recovery pool; low liquid level in sewage recovery pool, acid-base wastewater recovery pool and dosing pool Floating ball liquid level switch is used for alarm; liquid level detection and alarm in acid and alkali storage tanks are selected as external card liquid level switch of magnetic float liquid level gauge, and magnetostrictive liquid level transmitter is bundled.

(4) Flow meter

The electromagnetic flowmeter is used for flow measurement at the outlet of the filter pump, the acid-base jet booster pump and the outlet of the acid-base wastewater export pump. The lining of the electromagnetic flowmeter is PTFE, and the electrode material used for the acid-base wastewater is Hastelloy; Double rotor flowmeter is used for sewage oil flow measurement, and glass tube rotor flowmeter is used for coagulant, coagulant, degreaser and degreaser dosing pump outlet flow measurement.

(5) Valve

Electric butterfly valve is used to cut off the inlet of the backwash water tank; pneumatic butterfly valve is used to cut off the inlet and outlet of the acid-base jet, and the valve body, valve plate and valve seat of the pneumatic butterfly valve are lined with F46. All liquid level instruments installed on acid and alkali storage tanks are lined with PTFE, and acid and alkali medium flow detection instruments are lined with PTFE.
