Energy-saving and zero-emission multipurpose molecular-sieve dewatering device

Abstract

The invention relates to an energy-saving and zero-emission multipurpose molecular-sieve dewatering device. The energy-saving and zero-emission multipurpose molecular-sieve dewatering device comprises a first filtering separator, a first molecular-sieve dewatering tower, a second molecular-sieve dewatering tower, micro-pressurizing equipment, an electric heater, a cooling device, a separator and a second filtering separator. The energy-saving and zero-emission multipurpose molecular-sieve dewatering device is reasonable in design, novel in concept, simple in structure, convenient to operate, high in treatment efficiency, low in energy consumption, applicable to multiple working conditions, small in floor space, convenient to relocate, low in investment cost and applicable to the natural gas dewatering treatment of remote gas wells and the dewatering treatment of pipe network gas.

Description

Technical field [0001] The invention relates to the field of mineral fuel gas processing, in particular to an energy-saving zero-emission multi-purpose molecular sieve dehydration device. Background technique [0002] In the existing mining and utilization of fossil fuel gas, there are many problems, such as: [0003] 1. Associated gas, conventional natural gas, coal-bed methane, shale gas and sandstone gas in remote oilfields have not been developed and utilized for a long time due to the small gas volume, no users on the spot and far from the pipeline transmission system; [0004] 2. Low-yield gas wells are shut in for a long time, and productivity cannot be formed; [0005] 3. In the process of large-scale oil and gas field development, for some remote and scattered oil and gas wells, natural gas vented and burned still accounted for a considerable proportion. [0006] The above conditions will cause the fuel gas to be ineffectively used, or even emptied and burned. In today's energ...

AI Technical Summary

Problems solved by technology

[0003] 1. Associated gas, conventional natural gas, coalbed methane, shale gas and sandstone gas in remote oilfields have not been developed and utilized for a long time due to the small amount of gas, no local users and far away from the pipeline transportation system;

[0004] 2. Long-term shutdown of low-yield gas wells, unable to form production capacity;

[0006] The above situations will cause the fuel gas to be unable to be effectively used, or even to be emptied and burned. In today's energy shortage, it will not only cause astonishing waste, but also cause extremely serious pollution to the environment.
