The software package for solution of a wide range of tasks of the chemical and petrochemical industry described. The existing programs are analyzed and their advantages and shortcomings are specified. The shortcomings of these works have been taken into account at creation of the software package. Along with numerical methods for the solution of various tasks (calculation of integral, numerical methods for solving equations etc.), class for the solution of the direct and inverse problem of kinetics, calculation and a choice of the equipment from the Access database has been defined. The generated package can be used by schoolchildren, students, engineers and scientists.
