Natural Gas Applications and Integrated Gasification Combined Cycle
Applications and Processing of Natural Gas
Natural gas can be used directly as a fuel or as synthesis gas for the petrochemical industry. The transformations and products available are the same as those obtained from synthesis gas derived from crude oil refining. Natural gas is the cleanest natural fuel from a pollution standpoint, as it produces the least amount of CO2 per unit of energy of all fossil fuels. However, it is more difficult to store and transport than solid and liquid fuels.

Molding Methods
Hand Molding
As its name suggests, all operations in hand molding are manual, requiring highly skilled personnel. This method is only suitable for a very small number of pieces or parts that are very complicated and cannot be produced using other methods.
Mechanical Molding
In foundries with high production volumes and series production, mechanical molding methods replace manual methods for the manufacture of molds and cores. This offers the following advantages:

Milling Cutters: An Overview
What is a Milling Cutter?
A milling cutter is a cutting tool used in milling machines to remove material from a workpiece. It has several edges or teeth and rotates about an axis to perform the cutting motion.
Classification of Milling Cutters
Based on Tooth Type:
- Milled Teeth: Characterized by straight boundaries, these teeth cut with ease and provide good performance. They are sharpened by grinding.
- Straight: Teeth are parallel to the axis, with the full edge cutting the
