Embodiment 1

[0082] In a certain year, 1 million tons of oil, 600,000 tons of coal, and 600 million Nm of natural gas (associated gas and coalbed methane) are processed 3 and 2 million tons of salt to clean fuel oil, methanol, Cl 2 , soda ash and sulfur as the main products of the polygeneration system of chemical products is a demonstration device of the present invention, all material flows in this embodiment are measured in hours.

[0083] Petroleum enters the refining unit (1) with a processing capacity of 140t (sulfur content 1.51%, mass percentage), and after being processed by the distillation subsystem, about 43.76t of light oil and 63t of heavy oil are produced, and the heavy oil is coked After further processing by the cracking subsystem (12), 37.8t of petroleum coke (2.31% sulfur content, mass percentage) and about 19.2t of light oil products are produced, and the others are low-molecular organic substances. The fuel oil produced by the distillation subsystem (11) and the cokin...

Embodiment 2

[0098] In a certain year, 2.5 million tons of oil, 700,000 tons of coal, 200,000 tons of low-temperature pyrolysis semi-coke, and 1 billion Nm of natural gas (associated gas and coalbed methane) are processed 3 and 3 million tons of salt to clean fuel oil, synthetic oil, Cl 2 , soda ash, sulfur, high-purity CO 2 A polygeneration system for chemical products as the main product is an exemplary plant of the present invention.

[0099] The process is the same as the above-mentioned embodiment 1, except that the product synthesis unit (7) is a Fischer-Tropsch synthetic oil process to produce synthetic fuel oil. In addition, this system process will also extract part of the CO produced by the process. 2 Gas, exported as product. For convenience of description, this embodiment only lists process raw material consumption / product output and emission reduction effects.

Abstract

The invention relates to a method for co-producing various chemical products by taking coal, petroleum, natural gas and salt as raw materials. The method includes the steps of petroleum processing, slurry gasification, natural gas conversion, chemical product synthesis and salt electrolysis conversion. By reasonably using the coal, the petroleum, the natural gas and the salt resources, the energyand chemical overall goals of saving non-renewable resources and relieving environmental pollution can be achieved, and construction basis, solution and technical support are provided for Chinese large and super-huge energy industry base construction.

Description

【Technical field】 [0001] The invention belongs to the technical field of chemical industry, and more specifically, the invention relates to a method for co-producing various chemical products by using coal, petroleum, natural gas and salt resources as raw materials. 【Background technique】 [0002] In today's world, energy plays an increasingly important role in human life and social development, and human clothing, food, housing, transportation and other aspects consume more or less existing resources. With the continuous exploitation and conversion of mineral resources, the global energy crisis is further aggravating. At the same time, the living environment of human beings has been gradually changed or even destroyed. How to make good use of existing resources cleanly and efficiently, especially traditional non-renewable mineral resources such as oil, coal, natural gas (coal bed methane, associated gas), inorganic salts, etc., and how to use these limited resources to bene...
