What internal parts are used in the distillation tower for methanol distillation?

The float valve tray we use has greater operational flexibility.

Recommended vertical sieve plate tray for high efficiency and low investment!

The internal parts of the methanol distillation tower use vertical sieve plate trays, which have greater operational flexibility and better effects. You can contact the professional manufacturer Shijiazhuang Zhengyuan Tower Equipment Co., Ltd. They are relatively professional and have a lot of achievements.

Vertical sieve plates are commonly used. Many distillation towers now use vertical sieve plates, which have good mass transfer effects and are easy to maintain.

Methanol distillation tower is a typical chemical separation unit operation equipment. The gas-liquid mass transfer equipment used for distillation in industry is plate tower and packed tower. Generally, the more common plate tower is used in methanol distillation. The most commonly used trays in modern times are float valve type and sieve plate type, and those developed based on these two types of trays such as floating jet tower, floating tongue tower, inclined hole sieve plate type, inclined hole float valve type, guided sieve plate type, etc. For crude methanol distillation, these forms of plate towers can generally achieve the purpose of distillation well. The three-tower (pre-distillation tower, pressurized distillation tower and atmospheric distillation tower) processes all use floating valve towers. The main reason is that: (1) The tray structure is simple and easy to install. ； (2) The gas-liquid contact state is good and the tray efficiency is high ； (3) It can be operated under low load and has great operating flexibility. Since the valve plate can be freely raised and lowered to adapt to changes in gas volume, the allowable load fluctuation range for maintaining normal operation is wider than that of bubble cap trays and screen trays. ； (4) The allowed steam speed is large, so the production capacity is large.

Nowadays, more CTST trays are used.

Our company also uses a float valve tower for distillation. The operation effect has always been good, the product purity is high, and the operation flexibility is also great.

The introduction on the 7th floor is that now more and more CTST trays are used. In fact, the owner of zhangjingping on the 7th floor is a manufacturer of CTST trays!

At present, methanol distillation adopts three-tower distillation, which basically occupies a dominant position. The advantages and tower models are explained in detail by the brothers on the 6th floor. The three-tower distillation process is relatively energy-saving. The steam consumption can reach 1.1t/t of refined alcohol. This consumption level is unreachable by other distillation processes.

I also recommend the vertical sieve plate, which has a large kinetic energy factor, good separation effect, and is easy to maintain.
