Description The chemical dose filling skid is so called dosing and injection skid, odorization skid. or corrosive inhibitor skid. The chemical dose filling skid can be used for the dose filling of oil and gas field wellhead, gas gathering unit area, gathering pipeline, user pipeline and user gate station. Most of the filling media of chemical agent filling device are highly corrosive, and zero leakage must be ensured, so as to prevent the natural gas in the process pipeline from pouring into the filling system pipeline and causing accidents. The components of dosing and injection skid are: corrosion inhibitor pump, pump inlet stop valve, strainer (strainer to remove 5 m or more solid impurities), pump outlet with stop valve, check valve, safety return valve (outlet to pump inlet), nippler, pressure gauge, reflux bypass. Main functions 1. Skid replenishment for single well mobile corrosion inhibitor injection; 2. The skid internal corrosion inhibitor injection pump forms a corrosion resistant film on the inner wall of the gas collecting main line to slow down the corrosion of the gas collecting main line. Dosing device can achieve the following functions: 1. Remote start and stop of corrosion inhibitor pump and flow regulation. 2. Pump outlet pressure display. 3. Corrosion inhibitor pump status display. 4. Tank level display. 5. Corrosion inhibitor tank body pressure display. 6. Corrosion inhibitor tank fluid level display 7. Adequate maintenance space shall be left between internal skid equipment. 8. Noise control: at 1m from the sound source, the noise generated by the equipment shall not exceed 85dB(A). 9. The valve in the skid equipment and pipeline should ensure good sealing and wear resistance at the same time. 10. Meet the standard requirements of lightning protection and anti-static in the skid.(the distribution box, distribution box and other equipment with a ground mark shall be grounded; Valves and flanges for 4 bolts must be wire bonded. 11. Equipped with explosion-proof distribution box, starting switch and current and voltmeter with corresponding functions on the skid, protection level of distribution box inside the skid is not lower than IP65; The explosion-proof grade shall not be lower than dIIBT4.
