10.1.3.2 Co-processing of solid waste in the plant <BR>1. Waste alkali oxidation facility <BR>Steam cracking unit is used to build waste alkali oxidation facilities, using Siemens high temperature and high pressure wet oxidation process, with a designed processing capacity of 15t/h, responsible for the treatment of waste alkali produced in the refining part , Sulfur recovery device desulfurization wastewater and waste lye produced by steam cracking device. After oxidation treatment, the waste lye is converted into high-salt wastewater and discharged into the high-salt wastewater series of sewage treatment plant. <BR>2, the gasification furnace fine slag blended <BR>fine slag making the dry carbonaceous hydrogen gas generated in the gasifier means an amount of about 18%, there is a certain recycling value, to the power station boiler may be blended with further recovery Energy, reduce the amount of solid waste outsourcing. <BR>3. Solid waste incinerator The <BR>whole plant builds a solid waste centralized incinerator. The treatment of solid waste includes three categories: sludge from the sewage treatment plant, incinerable solid waste from the entire plant, and incinerable liquid waste from the entire plant. The incinerator includes a dehydration part, a drying part and an incineration part. The dehydration and drying are mainly for the sludge and scum produced in the sewage treatment plant. The dewatering design capacity is 500,000 t/a, and the drying design capacity is 13,000 t /a, the design capacity of incineration is 30,000 t/a.

10.1.3.2 collaborative disposal of solid wastes in the plant<BR>1. Waste alkali oxidation facility<BR>The steam cracking unit is equipped with waste alkali oxidation facilities. Siemens high temperature and high pressure wet oxidation process is adopted, with a design treatment capacity of 15t / h. It is responsible for treating the waste alkali liquid produced by oil refining, desulfurization wastewater from sulfur recovery unit and waste alkali liquid produced by steam cracking unit. After oxidation treatment, the waste alkali liquid is transformed into high salt wastewater and discharged into the high salt wastewater series of sewage treatment plant.<BR>2. Fine slag blending combustion of gasifier<BR>The dry carbon content of the fine slag produced by the gasifier of the gas and hydrogen production unit is about 18%, which has a certain recycling value. It can be sent to the boiler of the power station for mixed combustion to further recover energy and reduce the outsourcing amount of solid waste.<BR>3. Solid waste incinerator<BR>A centralized solid waste incinerator is built in the whole plant to treat solid waste, which includes three categories: sludge generated by the sewage treatment plant, incineration solid waste and incineration waste liquid of the whole plant. The incinerator includes dehydration part, drying part and incineration part. The dehydration and drying are mainly aimed at the sludge and scum produced by the sewage treatment plant. The dehydration design capacity is 500000 T / A, the drying design capacity is 13000 T / A and the incineration design capacity is 30000 T / A.

10.1.3.2 Cooperative disposal of solid wastes in the plant 1. Waste alkali oxidation facilities The steam cracking unit is equipped with a waste alkali oxidation facility, which adopts Siemens high temperature and high pressure wet oxidation process, with a designed treatment capacity of 15t/h, and is responsible for treating the waste lye produced by oil refining, desulfurization wastewater from sulfur recovery unit and waste lye produced by steam cracking unit. After oxidation treatment, the waste lye is converted into high-salt wastewater and discharged into the high-salt wastewater system of sewage treatment plant. 2. Mixing and burning fine slag in gasifier The carbon content in dry basis of fine slag produced by gasifier in gas-making and hydrogen-making plant is about 18%, which has a certain recycling value. It can be sent to power station boiler for mixed combustion to further recover energy and reduce the outsourcing amount of solid waste. 3. Solid waste incinerator A centralized incinerator for solid waste will be built in the whole plant. The solid waste treatment includes three categories, namely sludge from sewage treatment plant, incineratable solid waste and incineratable waste liquid. Comprises a dehydration part, a drying part and an incineration part of the incinerator, wherein dehydration and drying are mainly aimed at sludge and scum produced in sewage treatment plants, with a dehydration design capacity of 500,000 t/a, a drying design capacity of 13,000 t/a and an incineration design capacity of 30,000 t/a..
