Does the two-stage gas generator need desulfurization?
Whether the two-stage furnace needs desulfurization depends on the following conditions
1. sulfur content of coal 2. product gas requirements. If the sulfur content of the coal used in the double-stage furnace is relatively high, and the sulfide discharged after gasification exceeds the national standard, desulfurization is required; In addition, some products such as refined ceramics are greatly affected by the sulfur in the gas, and the sulfur content needs to be selected. Low gas is the heat source. In this case, the two-stage gas producer gas must be desulfurized.
What are the desulfurization methods for two-stage gas generators?
Dry desulfurization methods include: using swamp ore or artificial iron oxide as a desulfurization agent and using an activated carbon adsorption function to desulfurize.
Wet desulfurization: there are ADA method, arsenic alkali method, improved ADA method, low-temperature methanol method, and ammonia desulfurization method, as well as naphthoquinone method, polyethylene glycol methyl ether method, cyclobutane method and so on. But to sum up, wet desulfurization can be divided into three types: physical absorption method, chemical absorption method, and oxidation method. Two-stage gas generator desulfurization is commonly used for dry desulfurization.
As the first domestic manufacturer to develop two-stage gas generators, Jinan Huangtai Gas Furnace Co., Ltd boasts mature and stable two-stage furnace technology, with a market share of 70%. Hundreds of high-quality projects across the country have been running stably for many years.
