[0034] Example 1 like Figure 1As shown in the figure, this embodiment provides a rapid evaluation method for an offshore platform waste heat recovery (ORC) system, including the following steps: (1) Obtain the basic data of the waste heat ORC system of the offshore platform, and calculate the net power generation and power generation revenue of the ORC system within the economic life and the whole life cycle, and then calculate the economic benefits of the ORC system. (2) Based on the net power generation of the ORC system, the equivalent carbon emission value and carbon emission reduction environmental value are calculated; (3) The economic benefits and carbon emission reduction environmental value of the ORC system are evaluated based on the preset evaluation criteria to obtain the evaluation results of the ORC system.

[0035] Furthermore, step (1) above includes the following steps: (1.1) Obtain the basic data of the ORC system and divide it into two categories: operational data and cost data; (1.2) Based on the acquired power data, calculate the net power generation and power generation revenue of the ORC system within the economic lifespan and throughout its entire life cycle; (1.3) Based on the acquired cost data, calculate the investment cost of the ORC system over its economic lifespan and throughout its entire life cycle; (1.4) The economic benefits of the ORC system are calculated based on the power generation revenue and investment costs of the ORC system within its economic lifespan and throughout its entire life cycle.

[0036] Furthermore, in step (1) above, the ORC system in this embodiment is applicable to various large-scale equipment in the offshore oil and gas production field, such as offshore production platforms, drilling platforms, unmanned platforms, ship-type FPSOs, cylindrical FPSOs, and FLENG vessels. The heat sources utilized by the ORC system include various turbine generator flue gas, crude oil generator set flue gas, and waste heat from production water in the process flow.

[0037] Furthermore, in the above step (1.2), the operating data of the ORC system mainly includes power generation, power consumption of the working medium pump, and load rate; among which, the working medium pump includes the heat medium circulation pump, the organic medium circulation pump, and the seawater lift pump; therefore, when calculating the ORC power generation revenue, firstly, the annual net power generation of the ORC system is calculated based on the ORC system power generation, the power consumption of the working medium pump, and the load rate; then, considering the annual operating time and electricity price of the ORC system, the annual power generation revenue of the ORC system is calculated.

[0038] The net power generation of the ORC system is:

[0043] In particular, when converting ORC power generation into power generation revenue, it can be equivalently replaced by the natural gas, crude oil and other fuels consumed by the corresponding power plant.

[0044] Furthermore, in the above step (1.3), the cost data of the ORC system mainly includes equipment costs, maintenance costs, steel costs required for adding the ORC system, and hoisting costs required for installing the ORC system. Among them, the equipment includes waste heat boilers, heat medium circulation systems, ORC systems, heat medium circulation pumps, seawater lift pumps, instrument valve assemblies, control cabinets, etc.; maintenance costs include the operating costs of maintenance personnel, the impact of downtime caused by the unique operating time fluctuations of offshore platforms and extreme sea conditions, the power generation losses caused by ORC equipment downtime during maintenance and repair, and the economic costs brought about by starting the backup power generation scheme.

[0048] Furthermore, in step (1.4) above, when calculating the economic benefits of the ORC system, the economic benefits are mainly divided into the economic lifespan benefit and the life-cycle benefit. The calculation method involves discounting the annual power generation revenue of the ORC to the investment year and summing the results, then deducting the investment cost to obtain the economic lifespan benefit and the life-cycle benefit. Specifically, the economic lifespan benefit of the ORC system... Benefits throughout the entire life cycle for:

The economic lifespan and full lifespan are consistent with the economic lifespan and full lifespan of the offshore platform or FPSO to which the ORC system belongs.

[0051] Furthermore, step (2) above includes the following steps: (2.1) Convert the net electricity generation based on the ORC system into the equivalent value of carbon emissions; Based on the net power generation of the ORC system, the annual fuel savings in the production process are calculated. for:

[0057] Example 2 This embodiment is used to evaluate the economic benefits of an organic Rankine cycle power generation system on an offshore platform. The method in this embodiment includes the following steps: 1) ORC power generation revenue calculation: The net power generation of the ORC system is calculated based on the power output of the ORC system's generator, the power output of the heat medium circulation pump, the power output of the organic medium circulation pump, and the power output of the seawater lift pump. The calculation formula is as follows:

[0058] Because the operating load rate of offshore platform power plants varies from year to year, the amount of flue gas produced also varies, resulting in different annual net power generation of the ORC system. The annual net power generation of the ORC system can be obtained by combining the annual operating time. Based on the calorific value of fuel oil and the annual electricity price, the equivalent value of fuel savings and ORC power generation revenue can be calculated.

[0059] 2) ORC investment cost calculation: The investment cost of an ORC system includes equipment costs, maintenance and repair costs, steel costs for adding the ORC system, and hoisting costs for installing the ORC system. This example considers maintenance and repair costs of approximately 200,000 RMB per year, with the economic life ending in 2039. The discounted NPV over the economic life is 1.06 million RMB, and the discounted NPV over the entire life cycle is 1.36 million RMB.

[0060] 3) ORC economic benefit calculation: The economic returns of the ORC system are mainly divided into returns within the economic lifespan and returns over the entire lifespan. In this example, the economic lifespan extends from 2028 to 2039, while the lifespan extends to 2047. Based on the discount formula, the annual net present value (NPV) can be obtained. Calculations show that the total discounted return of the ORC system within the economic lifespan is 20.46 million yuan, and the discounted return over the entire lifespan is 26.31 million yuan. Considering the investment cost, the ORC system can generate a profit of 5.8 million yuan within the economic lifespan and 11.35 million yuan over the entire lifespan.

[0061] 4) ORC Carbon Reduction Environmental Value Calculation: This example project has an average carbon emission intensity of 0.24 tCO2e / a during its economic lifespan (2028-2039) without the addition of an ORC system. The total carbon emission cost of the project is approximately RMB 189.5747 million, with an average annual carbon emission cost of RMB 15.7979 million.

[0062] After adding the ORC system, the average carbon emission intensity of this project during its economic life (2028-2039) is 0.2341 tCO2e / a, a decrease of 2.46%. The total carbon emission cost of the project is approximately RMB 181.569 million, saving approximately RMB 8 million in carbon emission costs; the average annual carbon emission cost is RMB 15.1308 million. The total carbon emissions of the project are 1,364,354.99 tCO2e, a reduction of approximately 36,576 tCO2e.
