Due to the company’s expansion of production, it is now necessary to design an epichlorohydrin tank farm. I’m a beginner and don’t know where to start, what issues to pay attention to, or what criteria to follow. I’d like to ask the more experienced folks for their help and guidance. Thank you!~
In other words, similar design concepts for tank areas are all acceptable; take them as a reference! Thanks~
National standard number: 61052 CAS number: 106-89-8 Chinese name: Epichlorohydrin English name: 3-Chloro-1,2-epoxypropane; Epichlorohydrin English abbreviation: ECH Other names: 3-chloro-1,2-epoxypropane; epichlorohydrin Molecular formula of epichlorohydrin: C3H5ClO ; CH2OCHCH2Cl Appearance and properties: Colorless oily liquid with a chloroform-like irritating odor Molecular weight: 92.52 Vapor pressure: 1.8 kPa at 20°C Flash point: 34°C Melting point: -25.6°C Boiling point: 117.9°C Solubility: Slightly soluble in water; miscible with alcohols, ethers, carbon tetrachloride, and benzene Density: Relative density (water=1): 1.18 at 20°C ; Relative density (air=1): 3.29 Stability: Stable Hazard symbol: 14 (Toxic substance) Main uses: Used in the production of epoxy resins; also serves as a stabilizer for oxygen-containing substances and as a chemical intermediate. [Properties]: Highly volatile, unstable liquid. It has a smell similar to chloroform, mixes with most organic solvents, and is slightly soluble in water. Specific gravity 1.1761 (20/20°C) ; Boiling point 115.2℃ ; 9.78 pounds per gallon ; Vapor pressure 12.5 mm (20°C) ; Freezing point -25℃ ; Viscosity 1.12 cp (20°C), refractive index (n25/D) 1.4358; flash point 93°F (33.9°C) (TOC). 【Preparation】Obtained by removing hydrogen chloride from dichloropropanol. Impact on the environment I. Health hazards Routes of exposure: inhalation, ingestion, dermal absorption. Health hazards: Vapors are highly irritating to the respiratory tract. Repeated and prolonged inhalation can cause damage to the lungs, liver, and kidneys. Inhalation of high concentrations can cause central nervous system depression, which may be fatal. Steam is highly irritating to the eyes, and liquids can cause eye burns. Direct skin contact with liquids can cause burns. Oral administration can cause liver and kidney damage, and may be fatal. Chronic poisoning: Prolonged inhalation of small amounts can lead to neurasthenic syndrome and peripheral neuropathy. II. Toxicological data and environmental behavior Toxicity: It belongs to the medium toxicity category. Acute toxicity: LD50 90 mg/kg (oral, rats) ; 238 mg/kg (oral, in mice) ; 1500mg/kg (rabbit, transdermal) ; LC50 500 ppm, 4 hours (rat inhalation) ; When inhaled by humans at 20 ppm, the minimum concentration that causes poisoning (eye irritation) ; The minimum lethal dose for humans when administered orally is 50 mg/kg. Subacute and chronic toxicity: In rats exposed to 60 mg/m3 for 7 hours/day, 5 days/week, for 91 days, significant enlargement of the kidneys and an increase in brown pigment in the urine were observed. Mutagenicity: Gene mutations, positive in mouse lymphosarcoma cells. Teratogenicity: In vitro cytogenetic damage, positive for chromosomal aberrations in rodent bone marrow cells. Carcinogenicity: A positive tumor response was observed at the minimum subcutaneous toxic dose of 720 mg/kg in mice (over 78 weeks with intermittent administration). Hazardous properties: Its vapor forms explosive mixtures with air, and it can undergo decomposition and explosion as well as combustion in the presence of open flames or high temperatures. In the presence of high temperatures, it can undergo intense decomposition, leading to container rupture or explosion. Combustion (decomposition) products: carbon monoxide, carbon dioxide, hydrogen chloride. I found this online for everyone’s reference! ! ! Moderate toxicity; enhance monitoring! ! Should storage tanks be equipped with internal floating roof tanks! ! !
It’s best to find similar design materials; it’s necessary to determine the volume of the tank, the size of the pump, the flow process for material entering and leaving the tank, and whether a floating roof tank is needed – these matters should be discussed with the client.
