Pune Techtrol had recently been approached by Transworld Furtichem Pvt. Ltd. to provide level measurement solution for storage tanks of various chemicals including 33% HCl. Transworld Furtichem Pvt. Ltd. is the manufacturer and supplier of wide range of chemical and fertilizers. Pune Techtrol had this challenging assignment, as we had to offer them an optimum and durable solution for level measurement for 33% HCl which is reliable & cost effective.

The Hydrochloric Acid (HCl) acid is highly corrosive & toxic. Concentrated HCl releases dangerous fumes also called as acidic mists which can cause damage and cause irreparable harm to human skin, eyes, tissues or internal organs. Upon oxidizing of HCl, it produces toxic chlorine gas.

HCls handling requires extra precautions and care. The acid & its fumes corrode most of the engineering MOCs in a very short duration of time. This dangerous substance is generally used for steel pickling (removing rust or iron oxide scale from iron or steel before further processing), producing organic compounds, water treatment chemical, oil well acidizing, salt purification, household cleaner & leather processing. While handling it, one has to use protective gears like rubber gloves, boots, face shield, full suit, & vapour respirator. As such, handling & storing HCl acid presents many problems and difficulties.

Pune Techtrol provided ‘G-TROL’ transmitters and ‘IN-TROL’ transmitters which have successfully been used for continuous level measurements of 33% Hydrochloric Acid.

GTROL and INTROL are the transmitters based on radar principle, used for measurement of the level of liquids and solids. GTROL is a contact type of transmitter which consists of a probe connected to an enclosure containing signal converting electronics; whereas INTROL is a non-contact type of transmitter, unaffected by conductivity & density of the liquid, enabling level measurement up to 30 meters depth.

The tanks were of varying depths from small to large. Pune Techtrol provided them ‘G-TROL’, a contact type transmitter, fitted with PTFE coated suspended probe for small tanks having a depth of 2mtrs. However, for large tanks having the depth of 10 meters, the cost of ‘G-TROL’ was becoming prohibitive, as we had to provide them with a very long sensor in PTFE.

Alternatively, Pune Techtrol installed a non-contact type radar transmitter ‘IN-TROL’ for large tanks. Being a non-contact type it was easy to handle and also there are no chances of corrosion damage of the instrument, hence it will serve for a long period of time.

Both types of transmitters have been successfully installed & commissioned. All these devices provided, are closely monitored by the employees of Transworld Furtichem Pvt. Ltd.
