Problems solved by technology

[0003] ① Heating methods such as heat medium furnaces, water jacket furnaces, and fire tube furnaces have low heating efficiency and high operating costs;
[0004] ②Crude oil and natural gas are directly used as fuel for dehydration and heating of crude oil, resulting in waste of energy;
[0005] ③ The crude oil heating load of the combined station varies greatly with the seasons, and the heating furnace is used for heating, so the load adjustment is not flexible enough;
[0006] ④Environmental pollution is relatively serious
[0007] At the same time, the oil field has a large amount of waste heat resources that have not been utilized, which is a pity

Embodiment Construction

[0033] figure 1 It is the process flow diagram of the first embodiment of the heat pump crude oil heating system of the present invention

[0034] The heat pump crude oil heating system of the present invention includes a water / water heat exchange device 1, an absorption heat pump unit 2, a crude oil / water heat exchange device 3, a residual hot water pipeline 4, a medium-temperature clean water circulation pipeline 5, a high-temperature clean water circulation pipeline 6, and a crude oil pipeline 7.

[0035] The oilfield sewage or geothermal water with a temperature of 25-80°C in the waste water pipeline 4 passes through the water / water heat exchange device 1, exchanges heat with the medium-temperature circulating water, and transfers part of the heat to the medium-temperature circulating water, and the medium-temperature circulating water passes through the medium-temperature circulating water. The clean water circulating water pipeline 5 enters the absorption heat pump unit...

Abstract

The crude oil heating system is a system utilizing absorption heat pump system (steam type, hot water type, direct combustion type) to recover oil field sewage or geothermal water or heat quantity ofsolar energy to heat crude oil, and is characterized by that the waste hot water pipeline is connected with input end of absorption heat pump unit directly or by means of at least a water / water heat exchanger device, and the crude oil pipeline is connected with output end of absorption heat pump unit directly or by means of at least a crude oil / water heat-exchanger device.

Description

technical field [0001] The invention relates to a new crude oil heating system, which is a system for heating crude oil by using absorption heat pump system (steam type, hot water type, direct combustion type) to recycle oilfield sewage, geothermal water or heat from solar energy. Background technique [0002] As oilfield development enters the middle and later stages, the water content of oil wells is getting higher and higher, and crude oil dehydration and transportation require heating. At present, the heating of crude oil mainly adopts heat medium furnace, water jacket furnace, fire tube furnace, etc., and there are the following problems: [0003] ① Heating methods such as heat medium furnaces, water jacket furnaces, and fire tube furnaces have low heating efficiency and high operating costs; [0004] ②Crude oil and natural gas are directly used as fuel for dehydration and heating of crude oil, resulting in waste of energy; [0005] ③ The crude oil heating load of the...
