Abstract
There are many oil and gas fields in Indonesia which contain high CO2 that need to be treated. The Acid Gas Removal Unit (AGRU) is installed to remove the CO2. The AGRU will release the CO2 gas from the regeneration column. It still contains a high concentration of CO2 (higher than 80%). The accumulation of CO2 emission to the atmosphere will impact the environment. To promote environment-friendly technology, the process can be improved with conversion of CO2 into methanol. It will provide a relatively closed loop of the carbon cycle and as a renewable energy alternative. This study aims to provide packed bed reactor design which can be implemented in the small-scale methanol production plant utilizing high CO2 feed gas. The reactor temperature was varied from 200°C to 250°C and pressure were operated in the range of 40 Bar up to 75 Bar. These variations were used to analyze the effects of methanol production. The simulation results showed that peak methanol production rate was achieved at the temperature around 230°C. As the conclusion, the reactor showed better performance at the higher pressure and higher temperature although the reaction is exothermic including the recycling process can reduce the cost of hydrogen.
Highlights
In oil and gas industry, the well fluid is processed to remove unnecessary impurities such as CO2[1] from the natural gas prior to deliver the sales gas to the gas buyer to meet the quality as required by the gas sales specification.The sour gas which contains high CO2 component is mostly removed from the gas stream utilizing acid gas removal unit (AGRU)
The regeneration columns in AGRU will release a high concentration of CO2 that removed from the feed gas stream including water and some non-condensables to the atmosphere
This study aims to propose a packed bed reactor design for the small-scale methanol production plant utilizing high CO2 acid gas released from typical AGRU in oil or gas industries
Summary
In oil and gas industry, the well fluid is processed to remove unnecessary impurities such as CO2[1] from the natural gas prior to deliver the sales gas to the gas buyer to meet the quality as required by the gas sales specification. The sour gas which contains high CO2 component is mostly removed from the gas stream utilizing acid gas removal unit (AGRU). The membrane-based gas liquid contactor recently studied as the alternative technology for removing CO2 from natural gas[2]. AGRU used in coal gasification process to capture CO2[3]. The regeneration columns in AGRU will release a high concentration of CO2 that removed from the feed gas stream including water and some non-condensables to the atmosphere. The current increasing CO2 in the atmosphere is believed to impact the environment as greenhouse gas emission affecting the global climate change[4]
