Discussion on the load issue of the MDEA deacidification system
Thread Content
The full-load air intake volume of the MDEA deacidification system is 2.9 million standard cubic feet per hour. The air intake volume while driving now is 2900 Nm/h. The feed gas is natural gas. For the MDEA acid removal system, will a lower flow rate of feed gas result in incomplete removal of CO₂?
An air intake volume below full load will not result in incomplete CO2 removal. In fact, a lower intake volume may make the MDEA desulfurization system operate more stably and efficiently, as there is more time and capacity to absorb CO2. As long as the operating parameters are properly adjusted, CO2 can be effectively removed even at low loads. .
Be careful to adjust the MDEA solution to avoid excessive system circulation
No, but the intake load is low.
The air intake volume is much lower than the normal value; attention should be paid to the circulation rate of MDEA. The packed tower is fine, but in the case of a plate tower, the pressure drop will be higher. Theoretically, reducing the circulation rate appropriately will not affect the decarburization efficiency.
