(1) Can be based on the cold box outside the piping diagram provided by the equipment manufacturer and the relevant national standards and norms for industrial piping installation. For heavier weight valves, small lifting tools can be used to temporarily support them. When the piping is good, use fixed brackets to support. (2) Liquid discharge mains should be installed with compensation parts. (3) The aluminium pipe leading out of the cold box with its welded pressure plate and its seal ring s...

In order to reduce the air temperature in the low temperature air separation unit, various heat exchange equipment are needed for cold and heat exchange in various air separation systems, such as nitrogen water precooler, switching heat exchanger, main heat exchanger, condensing evaporator, subcooler, liquefier, vaporizer, electric heater, etc. These heat exchange equipments are installed in each system of the air separation unit, which are necessary for air liquefaction and gas separation. According to the principle of heat transfer, the heat exchanger of air separation unit can be divided into three types: 1. Dividing wall type: the cold and hot fluid is separated by the heat transfer wall, the medium does not directly contact in the heat transfer process, and the hot fluid transfers heat to the cold fluid through the heat transfer wall. For example, tube heat exchanger and plate heat exchanger. 2. Heat storage type: the cold and hot fluid alternately flows through the solid

What are the driving modes of compressors in large air separation equipment?

  Gas-liquid separation is one of the simplest and most common methods of gas pretreatment. Many process gases in industrial plants, such as steam reforming gas, conversion gas, methanol choke gas, etc., which are based on natural gas, contain only H2, N2, CH4, CO, C02, 02, H20, CH30H or some of these 'light' gases, which H20 orCH3OH, if enter the PSA unit in liquid form, this can cause damage to the performance of the adso...

The water supply source of air cooling column in precooling system equipment is cooling water pump, and water cooling column is supplied by chilled water pump. Their structures and principles are described as follows: 1. Design structure: the most basic components inside the centrifugal pump are high speed impeller and fixed volute pump case. Generally, the impeller with several (4 ~ 12) backward curved blades is fixed on the pump shaft and driven by the motor to rotate with the pump shaft at high speed. The work done by these impellers will directly act on the liquid in the pump body, which is the energy supply source device of centrifugal pump. 2. Principle: after the centrifugal pump is started, the pump shaft directly drives the reverse curved impeller to move at high speed, squeezing the pre filled liquid between the reverse curved spaces of the blade to rotate. Under the high-speed centrifugal force formed by the movement of the pump shaft, the liquid moves radially from th
