Liaohe Petrochemical has started construction of a hydrogen recovery unit for hydrogen-rich gas. Petroleum Chemicals Forum, 11/22, 11:00. As of November 7, 50% of the civil engineering work for Liaohe Petrochemical’s hydrogen recovery project has been completed; the next steps will involve the construction of the steel structures for the compressor building and the pipe corridors. Construction of this facility began on August 27; it utilizes membrane separation technology to recover hydrogen from hydrogen-rich gases containing high levels of the compound in question, achieving high purity and high yield. Once the facility is built, there are four advantages: first, it saves hydrogen resources and reduces waste. Secondly, it enhances the stability of the gas pipeline network, improves the calorific value of the gas, and boosts the safety of the heating furnace system. Thirdly, it can reduce the load on hydrogen production facilities, decrease the amount of naphtha or natural gas used for hydrogen production, and improve the company’s economic efficiency. Fourth, reducing the total amount of pollutant emissions is beneficial for environmental protection. Currently, Liaohe Petrochemical has 6 streams of hydrogen-rich refinery gas with high hydrogen content (mainly including the exhaust gases from hydrogenation units, light fraction gases, desorption gases, and gas oils). If these gases are burned as low-value fuel, it not only leads to waste of resources but also reduces the calorific value of the gas, causing instability in the gas distribution network and having a significant impact on the heating furnaces in various installations, thus posing certain safety risks. If the high-value hydrogen present in refinery gas is fully recovered, the hydrogen product can address the shortage of hydrogen needed for the upgrading and structural optimization of refinery oils. Additionally, it can reduce the operating load on existing hydrogen production facilities, saving hydrogen resources across the entire plant; profits can be generated by reducing the operating costs of these hydrogen production units. According to calculations, once Phase 1 of the project is completed, Liaohe Petrochemical will be able to recover approximately 6,000 tons of hydrogen per year (with a purity of 96.8%). Since the operating costs of the hydrogen recovery system are lower than those of the hydrogen production system, its use can reduce the overall cost of hydrogen production in the plant, resulting in significant economic benefits. Additionally, the approximately 30,000 tons of hydrocarbon components produced as by-products can be used as raw materials for downstream facilities. Therefore, recovering this hydrogen and light hydrocarbon resource can bring considerable economic and environmental benefits to enterprises. At the same time, by recovering hydrogen from the hydrogen-rich gas in the refinery, the calorific value of the gas increases, thereby eliminating potential risks. Installing such devices enables the efficient and high-quality recovery of hydrogen from refinery gas; it is an effective measure for Liaohe Petrochemical to reduce energy consumption, brings significant economic benefits, and also ensures the safe operation of the company.
