Abstract

The invention discloses a gas condensate separation device and a technical method. According to the gas condensate separation device, normal pressure tower bottom oil is subjected to pressure increasing using a pump firstly, and then is delivered into a side stripper reboiler as a heat source of the side stripper reboiler; at the same time, normal pressure tower undercooling feeding is adopted, wherein raw material gas condensate is subjected to heat exchange with fractionation products, and then is delivered into the normal pressure tower directly for heat exchanged of loaded materials in a tower, so that heat exchanged equipment is reduced, and dependence on common auxiliary heat sources is reduced, heat source concentration is capable of increasing heat efficiency, and reducing energy consumption, and equipment investment is reduced; and in addition, normal pressure tower top gas is delivered through a tower top gas heat exchanger, is cooled using a normal pressure tower top air cooler, and is delivered into a normal pressure tower top return tank directly, so that the operation temperature in the normal pressure tower top return tank is relatively high, more noncondensable gas is released, the saturated vapor pressure of tower top naphtha is reduced; a tower top water cooler is arranged on the tower top return tank, so that the operation pressure of the tower top noncondensable gas is higher, and it is more convenient for outer transportation.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a condensate oil separation device and a condensate oil separation process. Background technique [0002] Condensate oil refers to the liquid phase components condensed from condensate gas fields or associated natural gas in oil fields, also known as natural gasoline. Its main component is a mixture of C5 to C11+ hydrocarbons, which is lighter than crude oil, and its fractions are mostly at 20°C to 260°C. In addition, because the output is lower than that of crude oil, the processing scale is usually smaller and the process is shorter. Domestic condensate separation devices are mostly obtained from atmospheric distillation devices. Utilities and auxiliary systems rely on old crude oil plants, and fuel gas and steam are readily available. The existing condensate separation process is steam stripping. Such as figure 2 and heat conduction oil system heating method ...
