Description

Petroleum Coke Slurry Manufacturing Equipment

The present invention relates to an automated system for manufacturing slurry using petroleum coke.

In the 21st century, hydrogen is the main energy source along with natural gas, electricity, and ultra-clean fuel oil, and high value-added gasification/fuelization of renewable energy sources, electricity and CO2, is emerging. Clean and easy-to-use gas/liquid fuel oil is used. Expansion is expected, and there is a great need to secure hydrogen energy sources at an affordable price, but technology development and demonstration are required because economic feasibility is not yet secured.

In particular, in terms of the production direction of hydrogen, gray hydrogen technology that uses by-product hydrogen generated during reforming of fossil fuels such as heavy oil and natural gas or steel mills or refining and chemical processes as an energy source, low-grade coal, petroleum coke, and bio Blue hydrogen technology produces hydrogen by using mass and waste and reforms it to produce hydrogen, and green hydrogen technology that produces hydrogen through electrolysis of water using a renewable energy source. can be classified normally.

Therefore, it is judged that it is necessary to develop blue hydrogen technology for hydrogen production required by the market before entering green hydrogen technology rather than the demonstration stage. Plant, in the short term, clean syngas plants are considered to be a key sector in the overseas export plant market. It is judged to be a suitable field for the plant technology investment policy of overseas export and creation of national wealth.

In general, in order to produce hydrogen using petroleum coke, a slurry must be prepared from petroleum coke, which is a fuel. In the case of petroleum coke, it contains a large amount of oil and has fine particles, so it does not mix well with water and floats and aggregates.

As a result of directly manufacturing a slurry using petroleum coke, petroleum coke has a characteristic that it does not mix well unless the particles suspended on the water are physically stirred.

The technology related to the plant for petroleum coke hydrogen production of the present invention can be achieved through a number of fusion technologies.
