Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical production, and in particular to an apparatus for producing carbon black and methanol from methane. Background Technology
[0002] Currently, carbon black production commonly employs high-temperature cracking of petroleum coke. However, this process has several significant drawbacks: it involves a long process route, huge investment, high technological risks, high energy consumption, large carbon dioxide emissions, and a resource utilization rate of only 60%, resulting in resource waste and environmental pollution. If carbon could be fixed through catalytic cracking of methane, and the byproduct hydrogen could be used to produce green methanol, this would reduce investment and resource and energy waste, achieving comprehensive resource utilization and meeting energy conservation and emission reduction requirements. However, no relevant public reports have been found to date. Utility Model Content
[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a device for producing carbon black and methanol from methane, which can effectively solve the problems of high energy consumption, large investment, resource waste and environmental pollution of existing carbon black production equipment.
[0004] To achieve the above objectives, the technical solution provided by this utility model is a device for producing carbon black and co-producing methanol using methane, comprising a methane heat exchanger and a compressor. The hot outlet of the methane heat exchanger is connected to the inlet of a methane cracking reactor via a pipeline. The outlet of the methane cracking reactor is connected to the inlet of the methane heat exchanger via a pipeline. The cold outlet of the methane heat exchanger is connected to the inlet of a waste heat boiler via a pipeline. The outlet of the waste heat boiler is connected to the inlet of a carbon black separator via a pipeline. The hydrogen outlet of the carbon black separator is connected to the inlet of a scrubbing tower via a pipeline. The outlet of the scrubbing tower is connected to the inlet of the compressor via a pipeline. The outlet of the compressor is connected to the inlet of a methanol synthesizer via a pipeline. The outlet of the methanol synthesizer is connected to the inlet of a crude methanol distillation tower via a pipeline.
[0005] This utility model is scientifically and rationally designed, easy to operate, and makes full use of methane and waste carbon dioxide resources to produce carbon black products with low energy consumption, low investment, no pollution, and no carbon emissions, while also producing green methanol as a byproduct, which has significant social and economic benefits. Attached Figure Description
[0006] Figure 1 This is a system block diagram of this utility model. Detailed Implementation
[0007] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings and specific circumstances.
[0008] As shown in the accompanying drawings, an apparatus for producing carbon black and co-producing methanol using methane includes a methane heat exchanger and a compressor. The hot outlet of the methane heat exchanger 1 is connected to the inlet of the methane cracking reactor 2 via a pipeline. The outlet of the methane cracking reactor 2 is connected to the inlet of the methane heat exchanger 1 via a pipeline. The cold outlet of the methane heat exchanger 1 is connected to the inlet of the waste heat boiler 3 via a pipeline. The outlet of the waste heat boiler 3 is connected to the inlet of the carbon black separator 4 via a pipeline. The hydrogen outlet of the carbon black separator 4 is connected to the inlet of the scrubbing tower 5 via a pipeline. The outlet of the scrubbing tower 5 is connected to the inlet of the compressor 6 via a pipeline. The outlet of the compressor 6 is connected to the inlet of the methanol synthesizer 7 via a pipeline. The outlet of the methanol synthesizer 7 is connected to the inlet of the crude methanol distillation tower 8 via a pipeline.
[0009] To ensure better implementation results, the waste heat boiler 3 and the washing tower 5 are each equipped with a water inlet.
[0010] The pipeline between the washing tower 5 and the compressor 6 is equipped with a tee, and the bypass hole of the tee is connected to the carbon dioxide inlet.
[0011] In practical use, methane is fed into a methane heat exchanger 1 for heating, and then enters a methane cracking reactor 2 through the hot outlet. After reacting in the methane cracking reactor 2, it enters another methane heat exchanger 1 for cooling, and then enters a waste heat boiler 3 through the cold outlet. The waste heat boiler 3 adds water through the water inlet to cool the gas. The cooled gas is then sent to a carbon black separator 4 to separate carbon black products. The hydrogen gas after carbon black separation is sent to a scrubbing tower 5, where it is washed and purified by adding water through the water inlet. The washed hydrogen gas and the added carbon dioxide are then mixed through a three-way valve and sent to a compressor 6. The compressed mixed gas is sent to a methanol synthesizer 7, and the synthesized crude methanol is sent to a distillation tower 8 for distillation to obtain the product methanol.
[0012] It should be noted that all of the above-mentioned components are existing technologies and commercially available products. The contribution of this utility model lies in the scientific design and layout of these known components, which effectively solves the defects of existing technologies and meets production needs.
[0013] This utility model is scientifically and rationally designed, easy to operate, and makes full use of methane and waste carbon dioxide resources. It achieves the goal of continuously producing carbon black products by consuming methane and using by-product hydrogen and carbon dioxide to co-produce green methanol, thus achieving the purpose of carbon reduction and disposal. It completely changes the situation where the products produced by traditional coal gasification processes generate a large amount of unusable carbon dioxide emissions. At the same time, the use of methane catalytic cracking technology in the production process also greatly reduces energy consumption. It produces carbon black products with low energy consumption, low investment, no pollution, and no carbon emissions, while also producing green methanol as a by-product. It achieves green, energy-saving, and negative carbon emissions, with significant social and economic benefits.
[0014] It should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any person skilled in the art who can make changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution shall fall within the protection scope of the present utility model.
