Frequently Asked Questions

Common Industry Questions

What requirements need to meet if using the chemical packings?

Chemical packing is a type of solid filler widely used due to its ease of material sourcing, simple manufacturing, and low cost. Its primary function is to provide sufficient contact surface area between gas and liquid phases to enhance mass transfer efficiency in towers and columns.

How to choose tower packing?

The selection of tower packing should consider the requirements of the evaporation process. Key factors include high mass transfer efficiency, low pressure drop, high capacity, and good mechanical strength. Common types include Pall Ring, Raschig Ring, Intalox Saddle, Super Saddle, Tri-Pack, and IMTP, each suited for specific operating conditions.

What are the seven common petroleum refining processes?

From crude oil to final products, refining involves multiple processes such as distillation, cracking, reforming, alkylation, isomerization, hydrotreating, and coking. Each process converts raw materials into valuable products like gasoline, diesel, jet fuel, and petrochemical feedstocks.

What is the difference between activated alumina and molecular sieve?

Activated alumina is a porous form of aluminum oxide used primarily for drying gases and removing contaminants. Molecular sieves are synthetic zeolites with uniform pore sizes that selectively adsorb molecules based on size and polarity, offering higher adsorption capacity for specific applications like deep drying.
