Problems solved by technology

[0003] At present, domestic oil and gas field natural gas processing modular products are generally not highly integrated, and most of them are modularized for a single sub-function of oil and gas field processing. The process is simple, the scale of the equipment is small, and it is difficult to form a complete set of process equipment

Embodiment Construction

[0014] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0015] like figure 1 As shown, an oilfield modular treatment system includes a rectification skid, a cryogenic dehydrogenation skid, and a molecular sieve dehydration skid. The cryogenic dehydrocarbon skid is mainly divided into three areas: the low temperature area, the tower area, and the reflux tank reflux pump area. Among them, the low temperature zone mainly has multi-stream heat exchanger 1 , low temperature separator 2 and expansion compressor 3 . The tower area consists of a demethanizer 4, a deethanizer 5, and a liquefied gas tower 6 to form a combined tower platform. The demethanizer side line pump 7, the deethanizer reflux pump 8, the deethanizer top reflux tank 9, the liquefied gas tower reflux pump 10, and the liquefied gas tower top reflux tank 11 form the reflux tank reflux pump area. The multi-stream heat exchanger 1 is connected...

Abstract

The invention discloses an oilfield modular processing system. The system comprises a distillation sled, a cryogenic dealkylation sled and a molecular sieve dehydration sled; the cryogenic dealkylation sled comprises a multi-stream heat exchanger, the multi-stream heat exchanger is connected with a low-temperature separator, an expansion compressor and a demethanization tower, the demethanizationtower is connected with a demethanization tower lateral line pump and a dethanizer, the dethanizer is connected with a dethanizer top reflux tank, a liquefied gas tower and a dethanizer reflux pump, and the liquefied gas tower is connected with the a liquefied gas tower top reflux tank and a liquefied gas tower reflux pump. The system has the advantages of being simple in structure and reasonablein design, limitations that existing equipment cannot form a complete set, and the function is monotonous are overcome, the system has the advantages of being efficient, energy-saving, low in manufacturing cost, capable of achieving offsite relocation, large in treatment capacity, safe to run and the like, and good economic and social benefits can be created.

Description

technical field [0001] The invention belongs to the technical field of natural gas equipment, in particular to an oil field modular processing system. Background technique [0002] Modular manufacturing refers to the construction mode in which professional processes and products such as process engineering, automatic control, and mechanical equipment are highly integrated in the factory, and then transported to the project construction site for installation. In recent years, with the introduction of modular design and installation technology, the domestically produced large-scale oil and gas field processing modular devices have obvious cost advantages, and are increasingly recognized by domestic large-scale oil and gas field construction units. [0003] At present, domestic oil and gas field natural gas processing modular products are generally not highly integrated, and most of them are modularized for a single sub-function of oil and gas field processing. The process is s...
