Natural Gas Pre-Treatment And Purification System Including
Desulphurization decarbonization system
Process: (MDEA+MEA) mixed method (MDEA+ activator) MDEA method.
Dehydrating system
Dehydration by using 4A molecular sieve Process by using three towers (or two towers): less regenerative gas is needed; more stable in operation.
Molecular sieve dryer: It is designed in accordance with GB150 and tested by fatigue analysis.
Mercury removal system
The sulfur-loaded activated carbon is used to adsorb mercury, which can be used for 3-5 years. It is one tower or two towers, no need for regeneration. A filter is set behind the mercury removal system.
Aromatic hydrocarbon and heavy hydrocarbon removal system
From heavy hydrocarbon separator in the cold box, the heavy hydricarbon is separated and then adsorbed by scrubbing solution. After that, it goes out from tower bottom, gets separated, and at last gets stored in the storage tank.
Technical features
Low energy consumption for liquefaction, and low energy consumption mixed coolant refrigeration process (MRC) is preferred.
The process is mature and reliable, the process organization is advanced, and the operation and maintenance is simple. Only 3 operators are needed in one shift, and the start-up time is fast, and the time from start-up to product production is less than 3 hours.
High degree of integration. All of them are skid mounted, with small number of skids and small floor area.
Independent mechanical and electrical connection technology is adopted for the connection between skids, which is convenient and fast for installation, without welding on site, with good mobility and short installation period (20-50 days). Advanced system configuration, complete functions, priority to reliability, and reliable products are used for pipe fittings.
With remote diagnosis function, the response to user fault can be reduced to 1 hour through remote real-time data transmission.
The control cabin is adopted. The instrument and electric control cabinets are all placed in the cabin. The air conditioner is equipped in the cabin to meet the use requirements of electronic components. It is explosion-proof and easy to move.
DCS control technology and TCP / IP communication protocol are adopted. Compared with modbus, TCP / IP communication protocol has the advantages of wide utilization range, long communication distance and high speed.
Split skid mounted design, it has advantage of convenient installation and short construction period.
Standardized, modular plant design, the plant has advantage of compact structure, less land occupation, save investment, according to terrain and flexible layout, good stability and regional adaptability.
Use MDEA absorbing and removing acid gas (CO2).
Use molecular sieve and PSA dewatering process.
Removing mercury by activated carbon soaked in sulfur.
Liquefying natural gas with single level MRC refrigeration process.
The plant adopts DCS control system.
Packing & Delivery
Sound packaging and timely delivery. We take different packing approaches according to specific requirements. Wrapped bags and wooden boxes are commonly used for waterproof, dust-proof and shock-proof purposes, ensuring that every equipment remains in perfect condition after delivery.
