Thread Content
Several questions on basic chemical engineering theory are posed daily, and rewards are given for correct answers (the larger the reward for the first person to get it right). When the next set of questions is released, the correct answers for this round will be announced, and then it will be closed). 1. The main approaches to energy conservation in the chemical industry are: _______, ________, ________. 2. Pressure vessels are classified into four grades based on their pressure level; for example, the pressure value for low-pressure vessels is _______ Mpa, while that for high-pressure vessels is _______ Mpa. Answer key: 1. Rational energy use, safe energy use, full utilization of energy. 2. 0.098≤P
Low-pressure (code L) vessels: 0.1 MPa ≤ p < 1.6 MPa; Medium-pressure (code M) vessels: 1.6 MPa ≤ p < 10.0 MPa; High-pressure (code H) vessels: 10 MPa ≤ p < 100 MPa; Ultra-high-pressure (code U) vessels: p ≥ 100 MPa
Technological innovation, management innovation, industrial innovation: 1.57 MPa, 9.81 MPa. Additional information: Containers are classified into four categories based on the pressure they can withstand – low pressure, medium pressure, high pressure, and ultra-high pressure. The specific classification is as follows: (1) Low-pressure vessel p
I. Advances in process technology, structural adjustment, and management innovation II. 0.1MPa～1.6MPa, 10~100MPa
Question 1: Looking forward to your insights. Question 2: Vessels with a pressure in the range of 0.1 MPa ≤ p < 1.6 MPa are considered low-pressure vessels, while those with a pressure in the range of 10 MPa ≤ p < 100 MPa are considered high-pressure vessels.
My answer: 1. Technological innovation, management innovation, industrial innovation. 2. Vessels with a pressure range of 0.1 MPa ≤ p < 1.6 MPa are considered low-pressure vessels, while those with a pressure range of 10 MPa ≤ p < 100 MPa are considered high-pressure vessels.
Low-pressure (code L) vessels: 0.1 MPa ≤ p < 1.6 MPa; Medium-pressure (code M) vessels: 1.6 MPa ≤ p < 10.0 MPa; High-pressure (code H) vessels: 10 MPa ≤ p < 100 MPa; Ultra-high-pressure (code U) vessels: p ≥ 100 MPa； Article 1’s scope is too broad! ! ! :handshake
