Problems solved by technology

However, the actual production process is a dynamic process. The temperature, pressure, and composition in the reactor are all affected by factors such as feed, discharge, and operation. The steady-state model is not enough to solve actual production problems. Therefore, a Claus The dynamic model is particularly necessary in the process of sulfur recovery

Embodiment Construction

[0071] Such as figure 1 Shown, the object of the present invention is aimed at the reactor model in the Claus sulfur recovery process, proposed a kind of reactor dynamic modeling method in the Claus sulfur recovery process, the feed and discharge of reactor The condition is regarded as an unstable quantity, and the material composition inside the reactor at a certain temperature is solved according to the principle of atomic conservation and the minimum Gibbs free energy, and the heat loss is innovatively introduced into the energy balance equation, and the actual reactor is iterated through the balance equation temperature.

[0072] The acid gas involved in the Claus sulfur recovery process contains H 2 S, also contains CO 2 , N 2 and H 2 O, etc., acid gas from refinery gas, coke oven gas or water gas desulfurization unit may also contain NH 3 and HCN et al. Therefore, the actual reaction in the reaction furnace is very complicated, but the main reactions are as fo...

Abstract

The invention relates to a dynamic modeling method for a reacting furnace in the Claus sulfur recovery process. The method is a novel method for dynamic modeling of the reacting furnace in the Claus sulfur recovery process and firstly shows that including the heat loss into the energy conservation equation for performing iterative computation to judge whether the temperature in the reacting furnace is reasonable so as to calculate the ingredients in the reacting furnace according to the atomic material conservation, minimization of Gibbs free energy and energy conservation calculation; when calculating, the temperature in the reacting furnace and the quantity of each ingredient in the reacting furnace the Claus sulfur recovery process are assumed, the contents of the ingredients in the reacting furnace are calculated according to the material balance equation and the minimization of Gibbs free energy, and then whether the assumed temperature is reasonable can be determined according to the energy-balance equation. The dynamic modeling method for the reacting furnace in the Claus sulfur recovery process is the first time proposed, and brings a novel path for the dynamic modeling calculation of the Claus sulfur recovery process.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to a dynamic modeling method of a reaction furnace in the Claus sulfur recovery process. Background technique [0002] With the massive development of sour crude oil and natural gas resources in the world, the acid gases produced in factories and living processes have had a bad impact on the ecological environment. Therefore, sulfur recovery units have become large-scale natural gas purification plants, refineries, and petrochemical plants. It is an indispensable supporting device for processing sour natural gas and sour crude oil. Currently, the process of recovering sulfur by using the Claus process is an important part of natural gas or refinery gas processing. [0003] In recent years, the research on the Claus sulfur recovery process has mainly focused on the research of the catalyst in the catalytic process, the selection of the absorbent, the simplified calculation of...
