You could do it like this:

function clean(str) {
    var expressions = {
        '@~rb~@': '',
        '}':      '@~rb~@',
        // ...
    };

    for (var key in expressions) {
        if (expressions.hasOwnProperty(key)) {
            str = str.replace(new RegExp(key, 'g'), expressions[key]);
        }
    }

    return str;
}

Keep in mind that the order of object properties is not reliably determinable (but most implementations will return them in order of definition). You will probably need multiple constructs like this if you need to ensure a specific order.
