Carbon Dioxide Removal
Define the process
The removal of carbon dioxide, CO2 which is commonly found in most natural gas fields, in concentrations of up to 80 percent volume is vital to protect against downstream corrosion and maintain fuel point value. Petro Gasgen’s offering of CO2 removal technologies include membrane removal system, fluor solvent offshore process and acid gas fractionation with methanol system that can help ensure operators’ CO2 removal reliably meets their daily production quotas and equipment protection needs.
How It Works?
In a typical CO2 removal membrane system, the feed gas is first filtered to remove anyentrained liquids and aerosols. The gas then enters the membrane filters. The CO2 as well as the H2S and H2O permeate preferably through the membrane. The non-permeated gas, mainly CH4, remains at pressure and is the product gas.This technology combines high permeability with high hydrocarbon resistance, making it an attractive option for bulk carbon dioxide removal. In addition, the operation is highly flexible, it requires little maintenance, making it ideal for remote and offshore locations.
For fluor solvent offshore process, Pulverized Coal (PC) is used as the solvent because PC unit can operate with the low solvent circulation, recovering more hydrocarbon and is lower cost option when used to process high-CO2 gases. Refrigerant can be generated through theletdown of rich solvent using hydraulic turbine, eliminating external refrigeration requirement.
The acid gas fractionation with methanol system removes high acid gas stream using refrigerated fractionation configuration.
Key Benefits
I. Achieve or exceed natural gas production quotas via reliable CO2 removal from raw natural gases
II. Protect against fouling and blockage of flow paths by entrained solids
III. On-site equipment orientations and training for client personnel
Flour Solvent Offshore Process
In this process, we use Pulverized Coal (PC) as the solvent because PC unit can operate with the low solvent circulation, recovering more hydrocarbon and is lower cost option when used to process high-CO2 gases. Refrigerant can be generated by letdown of the rich solvent using hydraulic turbine, eliminating external refrigeration requirement.
Acid Gas Fractionation with Methanol System
We offer the system that will removed high acid gas stream using refrigerated fractionation configuration
