2.0.1 Natural gas condensate recovery device
A device used to recover condensate from natural gas by specific technical methods. When the cold separation method is adopted, it generally includes four parts: raw gas compression, raw gas dehydration, condensation separation and condensate fractionation.
2.0.2 Condensation separation
The process of partially condensing natural gas and separating natural gas condensate by using the refrigeration process.
2.0.3 Condensate fractionation
According to the difference in relative volatility of the separated components, the natural gas condensate is separated according to the product technical requirements. bZxz.net
2.0. 4 Refrigerant refrigeration technology
The process of using the endothermic effect of liquid refrigerant during phase change to produce cold air: the natural gas is cooled and partially condensed, and the condensate is recovered. 2.0. 5 Expansion refrigeration technology
The process of adiabatically expanding natural gas under high pressure to partially condense it after cooling and recovering the condensate. The process of using equal expansion to complete the expansion process is called throttle valve refrigeration, the process of using an expander to complete the variable expansion process is called expander refrigeration, and the process of using a heat separator to complete the variable expansion process is called heat separator refrigeration. 2.0.6 Commodity ethane
A quarry product with ethane as the main component that meets the relevant technical requirements or contractual provisions.
2.0.7 Condensation rate
The ratio of the amount of condensate condensed after the natural gas flow is reduced in temperature to the total amount of the flow, expressed as a molecular quotient fraction.
2.0.8 Yield
The ratio of the amount of a certain component (or a certain product) in the recovered condensate to the amount of the component in the raw gas, usually expressed as a molar percentage. 3
