A: working pressure (also known as operating pressure) refers to the top of the vessel in the normal process operation pressure. The maximum working pressure is the highest pressure that may occur during normal process operation. When the pressure exceeds this value, the 'safety device on the vessel has to be operated. The determination of the maximum working pressure and the working medium design pressure is the corresponding design temperature to determine the calculated wall thickness of the vessel and its component size pressure. It is stipulated in the Regulations for the Technical Supervision of Pressure Vessel Safety that the design pressure of the vessel shall not be lower than the maximum working pressure. The design pressure of the pressure vessel equipped with safety relief device shall not be lower than the opening pressure or burst pressure of the safety relief device. The working temperature of the pressure vessel is the temperature of the working medium inside the vessel during normal operation, i.e. the medium temperature. Design temperature is the container in the course of normal operation, in the corresponding design pressure, shell wall or component metal may reach the highest or lowest temperature. When the shell wall or component metal temperature is lower than 20 ℃, according to the lowest temperature to determine the design temperature, in addition to this, the design temperature is always selected by the highest temperature. The working temperature of the pressure vessel is the medium temperature, and the design temperature is the design temperature of the shell.

64. Chemical toxicity of common substances:
Chlorine (Cl2): yellow-green gas, soluble in water, alkali solutions, carbon disulfide and carbon tetrachloride. With carbon monoxide can generate more toxic phosgene. Chlorine dissolved in water to generate hydrochloric acid and hypochlorous acid, resulting in local irritation. It mainly damages the mucous membrane of the upper respiratory tract and bronchial tubes, causing bronchospasm, bronchitis and peribronchitis, and in severe cases, pulmonary edema. After inhalation of high concentration of chlorine, it causes vagal reflex cardiac arrest, which is ? electric shock-like? death.
65. Sulfur dioxide (SO2): colorless gas, density of 2.3 times the air. Liquefaction under pressure, liquid relative density 1.434, boiling point -10 ℃. Soluble in water, ethanol and ether. After inhalation into the respiratory tract, it generates sulfite and sulfuric acid on the wet surface of mucous membrane, producing strong irritation. Inhalation of large quantities can cause laryngeal edema, pulmonary edema, vocal cord spasm and asphyxia.
66. Carbon monoxide (CO): colorless, odorless, non-irritating gas. Density of air 0.968 times, insoluble in water, but soluble in ammonia, ethanol, benzene and acetic acid. The flame is blue when burning. Carbon monoxide is inhaled and enters the blood circulation through the alveoli. Carbon monoxide forms carboxyhemoglobin with hemoglobin. Carboxyhemoglobin has no oxygen-carrying capacity and is not easy to dissociate, resulting in hypoxia in all tissues of the body.
67. Hydrogen cyanide (HCN): colorless, bitter almond-flavored gas, density 0.94 times that of air, melting point -13.4 ℃, boiling point 26 ℃. Soluble in water, ethanol and ether. Dissolved in water to become volatile hydrocyanic acid. Hydrogen cyanide and oxidative cytochrome oxidase in vivo trivalent iron ions have a strong affinity, with which the solid combination, the enzyme is inactive, hindering the biological oxidation process, so that the tissue cells can not use oxygen, resulting in internal asphyxia.
68. Hydrogen sulfide (H2S): colorless, rotten egg odor gas, density 1.19 times the air, boiling point -61.8 ℃. Soluble in water, ethanol, glycerol, petroleum solvents.
