Acid Gas Recovery (AGR) Units for Sale

Used 7,000 BPD Gasoline Depentanizer Unit from an Oil Refinery built in 1995. The depentanizer is intended to control the vapor pressure of finished gasoline by removing pentane from the FCC gasoline stream after heat exchange with the bottom product. Overhead gas is condensed and accumulated in a receiver. Reflux is returned to the column and pentane routed to storage. The resulting low RVP gasoline is cooled and sent to storage. The depentanizer has never been used since it was built.

Used 650,000 TPY Aromatic Plant. The Aromatic plant includes several process sections: (1) Hydrogenation. The feedstock is hydrogenated through major equipment such as furnace, hydrogenation reactor and fractionating columns. Total capacity of this section is 620,000 tons per year. (2) Aromatic extraction. Here aromatics rich stream is separated from the paraffins; subsequently the individual components of the benzene-toluene-xylene (BTX) fraction or BT are separated from each other. The capacity of this section is 500,000 tons per year. (3) Distillation. This section process detailed separation. Fractionation has capacity of 260,000 tons per year, T5 370,000 tons per year, dealkylation 70,000 tons per year, and cyclopentane 10,000 tons per year.

Used 195 MMSCFD Acid Gas Recovery Unit (AGR) from a refinery complex, built in 2000. This AGR is originally designed to remove acid gases (hydrogen sulfide H2S and carbon dioxide CO2) from the raw syngas generated from a petroleum coke or coal gasification plant. This amine-process AGR can also be used to remove H2S and CO2 from the gases generated by oil refinery processing units and natural gas production plants. Feedstock syngas, containing carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and H2S, flows to the acid gas absorber to form the rich solvent. The purified syngas leaves from the absorber onto end uses such as a power plant gas turbine, boiler or furnace. The rich solvent flows to AGR splitter and other downstream equipment before the fluid of high concentration H2S goes to a Sulfur Recovery Unit, which finally produces element sulfur from the acid gas. This AGR uses MDEA (tertiary amines) wash for acid absorption and improves its performance by increasing the H2S-CO2 selectivity of the solvent in the absorber.

Used 1.68 Million M3/Day SNG Plant built in 1977. The SNG facility was constructed in 1977 but has seen very little operational activity. The SNG Facility employs hydro gasification process to convert naptha feedstock into SNG at a design rate of 1.68 million cubic meters per day.
