At Rama Phosphates Ltd, our mission is to be a major source for Fertilizer products where farmers can get multiple solutions and services.


Sulphuric Acid is considered to be the backbone of chemical industry and basic raw material and generally Acid means Sulphuric Acid. The elemental Sulphur fed and thus Sulphuric Acid is manufactured by using DCDA (Double conversion, Double absorption) system, which is the most modern method.

During the process, solid Sulphur is melted and that molten Sulphur is burnt in presence of excess dry air that ultimately passed through vanadium penta oxide catalyst in four stages. Sulphuric Acid is supplied in tanker loads and major consuming industries are pharmaceutical, soap, dye intermediates, industrial chemical, ammunition factory, fertilizers.

    OLEUM 23%

    This is variant of Sulphuric Acid and less corrosive in nature than Sulphuric Acid. In general Oleum is assessed according to the free SO3 content by mass. It can also be expressed as a percentage of sulfuric acid strength and commonly this is 123% of Sulphuric Acid.

    The main use of Oleum is in T N T (explosives) and also for manufacture of water based resins. Oleum is an important intermediate in the manufacture of sulfuric acid due to its high enthalpy of hydrogen. This also supplied in tankers load.


    The commissioning of Linear Alkyl Benzene Sulphonic Acid (LABSA) plant with 50 PD capacity is conceived at Udaipur unit in view of proximity of basic raw material 98% Sulphuric Acid availability in the vicinity from Hindustan Zinc Ltd. The another raw material is LAB [Liner Alkyl Benzene].

    LABSA is manufactured by sulphonation of LAB with Sulphuric Acid 98% in a continuous process and the reaction is highly exothermic which are controlled closely. Every process occurs automatically without human error to get better quality product & also sufficient quantity.

    LABSA is an intermediate chemical and practically all detergent formulations contain it as the active ingredient.

    The Spent Sulphuric Acid, a bye-product generated during the process of this manufacturing will be consumed for SSP fertilizer. Thus, this LABSA plant is a well laid-out strategy for vertical integration as a new product as well as forward integration for our SSP fertilizer.

    Moreover, this product has huge demand in sulphonation industries in Rajasthan, and nearby States like, U.P.,Uttarakhand, Haryana, HP, Punjab, MP, Gujarat etc.

    During our scintillating journey thus far we bagged Overall Best Performances Award instituted by Fertilizer Association of India for three years consecutively.
