在烃类的开采、加工和储运过程中减少其损耗,不仅对靠扩大原料烃的销售来提高生产效率具有重大意义,而且对改善石油与天然气采区的生态环境也具有同样的意义。考虑到烃类损耗发生的主要原因是由罐内蒸发而引起,所以提出以下技术与工艺方案。 1、气体密闭储罐和冷却箱与原油消极稳定工艺流程图(见图1)。原油从末端分离器进入储罐9中,储罐与冷却箱3气体密闭5,冷却箱由地上卧式分离器和集管8构成,集管的下端卧入地下两米。春夏季节集管8内的温度,以及秋冬季节分
Reducing losses in hydrocarbon production, processing, storage and transportation is of great significance not only to increase production efficiency by expanding the sales of feedstock hydrocarbons, but also to improve the ecological environment of oil and gas fields. Taking into account the occurrence of hydrocarbon loss is the main reason is caused by the evaporation tank, so the following technology and process proposed. 1, gas-sealed tanks and cooling tanks and crude oil negative steady flow chart (see Figure 1). The crude oil enters the storage tank 9 from the end separator, the storage tank and the cooling tank 3 are hermetically sealed 5, the cooling tank is composed of a horizontal horizontal separator and a header 8, and the lower end of the header lies two meters underground. Spring and summer temperature within the header 8, as well as autumn and winter seasons
