The invention discloses a mercury-containing natural gas fluid purification treatment device which comprises a purification tower, a feeding pipe is inserted in the side wall of the purification tower in a penetrating mode, a discharging pipe is inserted in the top of the purification tower in a penetrating mode, a purification liquid box is fixed to the outer wall of the purification tower, and a main purification pump communicating with the interior of the purification liquid box is fixed to the upper end of the purification liquid box. The invention relates to a purification treatment method of mercury-containing natural gas fluid. The purification treatment method comprises the following steps: connection and inspection of equipment, conventional mercury flow purification, circulating pretreatment and mercury liquid recovery. The purification treatment device and method have the advantages that the main purification pump and a spray head are arranged, the main purification pump transfers purification liquid in the purification liquid box into the purification tower from a main spray pipe, and the purification liquid is sprayed out of the spray head and scattered from the upper portion of the purification tower to the lower portion of the purification tower, so that effective and uniform distribution of the purification liquid in the purification tower is achieved, and mixed airflow flows upwards from the bottom of the purification tower; and therefore, the air flow is mixed with the purification liquid in the purification tower, and the mixed air flow is purified.
Description
technical field [0001] The invention relates to the technical field of natural gas treatment, in particular to a purification treatment device and method for mercury-containing natural gas fluid. Background technique [0002] With the massive development of global natural gas resources and the application of natural gas as a clean energy in industry and civil use, natural gas plays an increasingly important role in the energy field, and the natural gas mercury removal process has become an important part of natural gas processing and treatment . [0003] Mercury is a common harmful heavy metal element in natural gas. Considering environmental protection, human health, and safe development of mercury-containing natural gas, mercury in natural gas must be removed. At present, mercury removal from natural gas mainly adopts non-renewable chemical reaction adsorption Due to the large amount of adsorbent used, the price is expensive, and the waste adsorbent after demercuration an...
