Acetylene Plants

We are a reputed and known company for manufacturing and exporting acetylene gas plant, which are technologically very advanced and work as per the plants of international standard. In order to incorporate the latest technology, we associate with “Felice Mandressi” of Italy whose technology is proven worldwide for unmatched features. The acetylene generator plants manufactured by our company can contend the plants of international standard as we use the best manpower and raw materials from CE approved vendors. We manufacture the plants keeping in mind environment and safe.

Available in different capacities ranging from 25 m3/hour to 100 m3/hour; therefore acetylene plants are chosen by clients located all over the world. Our association with internationally approved Italian company helps us to integrate the best technology available. We take the designs & drawings of “Felice Mandressi” of Italy and modify them by experienced engineers to perfection. The whole operation of acetylene plant is accomplished perfectly to give maximum efficiency and simplicity in operation. Any type failure, whether it is of power supply, water or instruments air, is signalled visually as well as audibly to alert the operator.

We form a team of customer care executives in order to solve the day to day queries of customers. Anyone can call to get queries solved about the acetylene plants by our technical experts.

Introduction

BDM Cryofusion & Mandressi ITALIA is one of the Leading Manufacturers and suppliers of acetyelne gas plant with Société Générale de Surveillance (SGS) quality approval and ISO 9001:2000 certification.

Acetylene (C2H2), a compound of carbon and hydrogen, is a colorless, highly flammable gas. It is slightly lighter than air and has a garlic-like odor. Acetylene is stored in high pressure cylinders filled with a porous material and contains acetone, into which the acetylene is dissolved.

Unless it is dissolved in a solvent, acetylene will dissociate at pressures above 15 psig and form lamp black and hydrogen. Heat is generated with dissociation, which in turn, produces a danger of explosion. Acetylene is manufactured by the reaction of water with calcium carbide. It is also manufactured by thermal cracking of hydrocarbons, or by partial combustion of methane and oxygen.

CHEMICAL FORMULA USED:
CaC2+2H2O = C2H2 + Ca (OH) 2 + 27,000 Calories

Acetylene has become increasingly prominent as a raw material for a whole series of organic compounds, among them Acetaldehyde, Acetic gas, and Acetic Anhydride. The remaining 20% of the acetylene production is principally employed for oxy-acetylene cutting, heat treating, and welding.

The acetylene plant is fully automatic and all the operations are carried out automatically by pneumatically controlled valves along with latest sensors and temperature controller imported from USA.

Acetylene is generated as a result of the chemical reaction between the calcium carbide and water. The by-product calcium hydroxide is discharged automatically from the generator. Acetylene gas burns along with oxygen as a cutting & welding torch and it offers the highest temperature of any known oxygen gas mixture.

Process Description

Acetylene is generated as a result of the chemical reaction between the calcium carbide and water. The by-product calcium hydroxide is discharged automatically from the generator. Acetylene gas burns along with oxygen as a cutting & welding torch and it offers the highest temperature of any known oxygen gas mixture.

The entire operation is perfectly synchronised to offer maximum efficiency and simplicity in operation. Any failure, whether it is of power supply, water, instruments air, is signalled visually and also audibly when an alarm bell rings to alert the operator.

Only flame proof lights and electrical fittings according to IS2148-68 (Group II) or BSS-229 may be used in an acetylene plant building. Acetylene cylinders must be of specification IS: 7312: 1974 or ICC:8.
